and bears a prominent hair at each anterior angle. There 

 are also three pair- <>t' hairs situate*! on (lie forward part of 

 the clypeus and t\vo pairs directly between the eye-, one 

 ])air being on the 1 cly])eus and one on the epieraniuin. 

 Antenna 1 setaceous, four jointed and ferruginoi.-. Kyes 

 conspicuous, and situate*! in groups of six each, on slight 

 elevations just behind the antenna'. The mandibles are dark 

 brown in color, long, simple, stout at base, but <|iiite pointed 

 at the tip, the left mandible often folded over the right . The 

 maxilla 1 and labium are small, ferruginous and provided 

 with well-developed palpi. Prothorax large, as long as the 

 me-o- and meta-thorax, slightly contracted and rounded 

 posteriorly. Meso-thorax slightly rounded posteriorly : 

 meta-thorax truncate. Lateral edges of the bodv segments

slightly produced. Dorsal line prominent on all the seg- 

 ments except the last. On the dorsuin of each thoracic seg- 

 ment there are ten short hairs, one on the anterior part of 

 each lateral margin, one at each angle of the segment and one 

 on each side of the dorsal line at the anterior and posterior 

 margins. Abdominal segments, nine in number, with the 

 exception of the last, truncate behind, the last segment being 

 rounded posteriorly and bearing a pair of caudal appen- 

 dages. Each segment except the last bears six hairs, one 

 on each lateral margin and two on each side of the dorsal 

 line at the posterior margin. The last abdominal segment 

 bears a pair of hairs on each lateral margin, but none on the 

 dorsuin. The caudal appendages are entire, although prob- 

 ably jointed at the base, and bear numerous hair-. The 

 spiracles are situated just below the dorsal plates. The 

 ventral portion of the body is of a yellowish white except 

 the portions which are strengthened by chit inous plates. 

 These are of the same color a- the dor-al part of the body. 

 Legs well developed, provided with -tout spine- which are 

 e-pecially prominent at the joints, the tarsi hearing two 

 claw-. The last body segment hears on the posterior 

 ventral portion an appendage which serves as a proleg and 

 aids in locomotion. The larva remains in this stage about 

 four days. Molting is accomplished by a splitting of the 

 thoracic plates along the dor-al line : the head, mouth parl- 

 aild legs are then withdrawn and the exuvia- forced back
