Translation by Sherlock:
Marilia sp. 2 = Marilia siolii n. sp.
(Pl. XXXVII; fig. 1-10.)
Adult
The debris of the broken up adult which were find in this exuvie nymphale cannot obviously provide us a complete description, however we can quote some characters of systematic importance here. The formula calcarien is not 2/4/4; the posterior femurs present towards their end an external line of 16 long sensory silks inserted in a soquet surrounded of a hyaline aureole slicing on the entirely testacée color of the appendix.
The genitalia show a ninth segment finely velvety; the gonopodes are short, statements towards the face dorsal, biarticulés, the rather thick basal segment with an external ventral peak and very many umbilicated silks; it seems, with the interruption of the external peak, divided into two; on the whole it reaches three times the distal record length; this one small, oval, is rounded with the end with very short spines below and at the end. There is a sheath with the penis, foliaceous, dilated with the end, somewhat out of broad and blunt spearhead: this sheath is not other than the tenth segment flattened and widened in wings. The penis is cylindrical and extends lengthily inside the abdomen. The préanaux appendices are lengthened, hardly narrowed with the end, extremely hairy, at node rounded, they exceed the gonopodes backwards but are a little shorter than the sheath pénienne. In spite of the insufficiency of the characters known up to now it is very probable that this species quite distinct from Marilia is known to date.
The absence of the wings does not make it possible to usefully compare them with the already known species which were especially described on the basis of wing characteristic. We are pleased to give to this new species the name of its recoltor, Dr. H. SIOLI, which always expressed for our work a great interest.
