head from the anterior margin. A row of about 6 small spines extending across 
near the anterior margin dorsally and a longitudinal row on each side with 
about 6 spines. One short spine in front and 2 behind each antenna and also 2 large 
spines toward posterior edge of head medially. Ventrally a spine of moderate length 
on each side behind and mesad of base of antennse. Mouth parts slightly ventrad of 
anterior extremity, a chitinized transverse ridge 
running across the anterior margin just above the 
mouthparts. 
Thorax. —Much as in female, a few short and 
one long spine on either side of pronotum and meso- 
notum. Spiracles on pronotum and mesonotum 
prominent. Sternal plate more elongate than in 
female and slightly concave on lateral border. 
Abdomen. —Greatest width at about fourth 
segment, elongate oval. Second to eighth segments 
provided with projecting spiracles as in female, 
ninth segment with a distinct notch on either side, 
the central terminal portion being rather stout and 
bearing a number of small spines along the border. 
On the dorsal side segments armed submedially as 
follows: The first segment with two transverse rows, 
anteriorly to these 6 small spines and posteriorly 
about 8 spines, the two median being the largest; 
second segment, 8 spines; third, 6 spines; fourth, 
8 or 10 spines; fifth, 8 spines; sixth, 8 spines; 
seventh, 6 or 8 spines; eighth, from 4 to 6 spines. Near lateral margins another row 
of spines, one spine to each segment, those on seventh and eighth segments being very 
long and hairlike, those on first segment small. Ventrally, the second to seventh 
segments with a row of 4 spines submedially and the eighth with 2 spines. All ventral 
spines somewhat stronger than the dorsal ones. Near the lateral margin the second 
tp eighth.segments provided with a single spine on either side, those on seventh and 
eighth segments being long and hairlike, as on the dorsal surface. 
# Qenital frame (fig. 5) rather simple, apparently consisting of 
six parts. Basal portion forked for about one-fifth of its length 
at the posterior end where it articulates with two elongate 
plates which in turn join at their posterior end with two other 
plates of slightly greater length. These diverge posteriorly and 
bend dorsally and cross the anterior ends of a wishbonelike 
plate the posterior end of which terminates in a rather acute, 
highly chitinized point known to some as the pseudopenis. 
The penis is simple, nearly equaling in length the inclosure of 
the frame, the aperture situated well back between the legs of 
the wishbonelike plate.

First instar, color pale yellowish before feeding, except for illalus: Genital frame - 
parts of abdomen which are darker; after feeding, much as in X 
adult though somewhat paler; tarsi and claws yellowish to light brown. Later instare 
darker. 
Head. Showing slightly stronger transverse groove than in adult. 
Thorax— About as in adult, but slightly less chitinized.
