medium and diramified, hair 8 ramified and 
very well developed; Segment VIII, hair 5 me- 
dium and simple, hair 8 multiramified, very 
well developed and spiculated. Pupal trum- 
pets longer than wide, with a triangular open- 
ing, rounded at the angular borders, tapering 
and very sinuous. Pupal paddles rounded with

which form an overlapping tuft toward the 
clypeus, and bordering the eyes. Occiput dark 
with plumous scales as on the vertex. Pro- 
thoracic lobes revetted with golden scales and 
dark hairs. Mesonotum with 3 strips of small, 
compact brown scales forming circular spots 
at the wing base, the disc revetted with small 
golden hairs, with clear spaces among the 
compact scales. Scutellum trilobate with the 
median lobe larger than the others, with gold- 
en scales as on the mesonotum, with long 
dark hairs on all the lobes. Postnotum bare 
of scales, light brown. Abdomen olive brown,

inent, short, with 3 sinuous rods, median one

tubercular bases, lobe also bearing very thin 
hair-like filament slightly curved at tip and 
shorter than rods. In addition, subterminal 
lobe with very large ovate leaf and long rod-
