The second section, limited in the European fauna, to the genus Odontocerum, belongs to the two species whose tubes are constructed of small stones as seen in fig. 1: and 1,5 of Est. VIII (Vol. III of the Archivos). These genera will have to constitute one new, for which I consider the name of Marilia, calling the two species Marilia major (fig. 14) and Marilia minor (fig. 15). This new genus is distinguished from Odontocerum by antennas not indented, by the enormous eyes of the males (touching in the vertice of the males of the Marilia minor, and separate for one intervallo alone narrow in the ones of the Marilia major), for the ray ("radius") and the first apical sector will confluirem in azas previous as in such a way posterior, and for other characters. The two species of Marilia, whose houses I described, frequent various brooks. a third species, to that it seems, rarer, whose larvae I found in the river Itajahy. The houses to differem of the ones of the Marilia major quasi that for being only very short; therefore it is excused to give to a figure of them; have-if-ha a idéa exacta of its form imagining itself cut to the posterior half of the houses of the Marilia major. (Est. VIII, fig. 1.1, To). Alone the house of this third species that now I have, tern 6mm of length, being diameter of the entrance of 2 and of the posterior extremity (of 1, mm5. The posterior extremity is covered, corno in the other Marilia, for a transversal wall with elliptico hole in the superior part. It fulfills to notice that it substantiates it of that this wall is made and with that others are found an ace grudadas, small stones of the house, is very pale, almost without color, in how much black or medium brown dark in the two others species.

Marilia major Fr. Mull.
(Tafel III. Fig. 91, 92,)
Basic colour of the heading dark-brown, which large black eyes stand together on the Dorsalflaeche so closely that only a narrow, space between them, covered closely with whitish hair, remains. Feeler threadlike, more than twice as long like the forward wings, brown, from fourth to for instance to the tenth member narrowly black at the Articulationen, which know the following members in the distal half; first member remarkably largely, as long as the heading, second member small. Lower surface of the heading together with the tracers likewise with close bright hair trimming; Kiefertaster strongly, second member somewhat more largely than third, fourth and the fifth bent member still more briefly, basic member briefly, thickly; at the inner edge the Behaarung of the tracer is particularly close. Lip tracer tenderly, three-membered. Pro thorax very small. Chest red-brown, Mesonotum at the pages more darkly, those whole lower surface brightly behaart, top side naked. Abdomen red-brown. Legs yellow-red, rails and Tarsen more or less darkly, everything, with exception of the thighs closely and briefly whitish behaart; Spur number of 2, 4, 4 (m); Interiorspur more largely as if externalspur, the Subapicaisporne of the central legs (these are importantly larger than those of the hind legs) be very far basalwaerts on the rail. The forward wings (Fig. 91) are narrowly and long, after that Apex few widened, the Apicalrand almost even, the Hinterfluegel very broadly (M), folding, triangular. Diaphragm of the wings somewhat clouded, which forward wings more yellowish, which rear more grey, both with blackish Behaarung, under which however, particularly on the forward wings, on mid lightyellow hair numerous beside the longitudinal veins AUDI are visible; Edge lashes show up only in the Hinterfluegel, it are mixed from blackish and gold-yellow hair. Nervatur (Fig. 91) particularly in the Hinterfluegel peculiarly, in both is available a long closed Discoidaizelle; in both the radius unites briefly before its end with the first Apicalsector; Median cell being missing, fork 1 and 2 available; in the Hinterfluegel the fifth Apicalader flows into sixth, thus to a certain extent a false median cell is formed. - abdomen red-brown. The genital appendices (m) point to relationship with Odontocerum (Fig. 92): Tergit of the last segment in the center of the Hinterrandes triangular preferred, ventralwaerts of it an extension, under which the Penis hides itself, the upper appendices strongly, curved; the lower more briefly, by the page regarded, toward the end gradually diminish becoming; Anliaenge long behaart.
Body length: 11 mm; Wing length: 30 mm.
1 time collected from Santa Catharina, of Luederwaldt (26 January), in the Stettiner museum. I believe that one belongs to the this type available in the Stettiner museum from Santa Catharina; it has also the spur number of 2, 4, 4; on the forward wings are more numerous light places. The Hinterfluegel is much diminishes as with and has somewhat deviating Nervatur (Fig. 93). A second just as large has only 2, 4, spurs and differs also otherwise, third is quite small and belonged perhaps to Marilia minor Fr. garbage. So for a long time however further does not admit is, would like I the 2 latter to describe
Body length of the F von Marilia major: 7 mm, wing voltage: 20 mm. - body length of the F von Mar. minor (?): approx.. 6 mm, F1uegeßpannung approx.. 1,7 mm; this latter has 2, 4, 2 seem-spurs.
Could general be said about the Marilia types: The spur number is alike either to 2.4.2 or 2, 4, 4, but in the types; the mm have broader Hinterfluegel than the FF. At least 4 types, of it 3, existiren each other in the colouring similar, in Santa Catharina.
