the usual 4 pairs of bristles; with a fine line outside of bristle 

 II running backward and so separating a median streak from 

 the lateral streaks; with about 11 transverse rows of extremely 

 minute triangular deuticulations in the median part of the 

 middle field, of which the four foremost rows are convex forward, 

 and the two hindmost rows consist of a double curve forward. 

 Between hairs III a pair of triangles with sharp point for- 

 ward. Horns normal, inner malae fused to form a median firm 

 triangle which ends in the two usual slips and has fringe on 

 its sides. Palps. The femur dorsally (fig. 39) with a central 

 hair and with a distal and inner transparent pin, both directed 

 inward aud forward. Ventrally (fig. 45) the trochanter with a 

 proximal inner chitinous triangular sharp pin, a distal inner 

 small sharp pin, a distal outer ditto and the usual two bristles, 

 of which the distal and inner one is distally hairy. The femur 

 with an outer bristle and an inner knife-shaped hair in the 

 middle of its length ; the sharp edge of it forward and the 

 blunt edge armed with two narrow and sharp teeth.' Genu 

 inward with the usual two knife-shaped hairs, truncate distally. 

 Tibia and tarsus normal. The palp is comparatively thicker 

 than in P. coleoptratorum (L.). 



Legs (fig. 39) slender, resp. about 1625, 1155, 1155, and 

 1735 i^ long. On femur aud genu II, femur and genu III, 

 and femur IV there is a median and distal rod-like and dis- 

 tally hairy hair (fig. 41); further there are several such hairs 

 on genu, tibia and tarsus IV, most of them standing perpen- 

 dicularly to the axis of the joints. Tarsus IV distally (fig. 46) 

 without any pins, bat provided with the two short supraprae- 

 tarsal (sence-V) hairs. Praetarsus IV (fig. 46) slender, distally 

 with a four-lobed supraunguinal sticking piece, and a single 

 flat, almost triangular sub-unguinal caruncle. Between the claws 

 a tear-shaped, light refracting thing.
