DESCRIPTION OF LARVA, PUPA AND CASE 



Larva 



The length of the mature larv'a (Fig. 7) is about 12 mm., its 

 breadth is about 2.5 mm. In life the soft parts are green; the 

 heavily chitinized parts are dark brown, appearing black when 

 viewed in reflected light. The abdomen tapers gradually from the 

 first to the last segment. 



The head is black, marked with brown on the dorsum (Fig. 7) ; 

 the sides are black with a brown mark extending back from the 

 caudal margin of the eye to the caudal margin of the head as shown 

 in the side of the figure; the venter is black, except the ventral 

 mouth-parts which are brown ; the labrum is black with sets ar- 

 ranged (Fig. 2) ; its cephalic pair of setae are saber-like and are 

 directed toward the median line, their tips almost meeting, the other 

 sets are normal, the front margin is clothed with a dense fringe 

 of hairs; the frons has the markings and distribution of setae shown 

 (Fig. 13) ; other mouth-parts are shown (Figs. 4 and 5). 



The thorax is marked on the dorsum (Fig. 7) ; the prothorax 

 has a depressed crescentic mark of brown across the dorsum and ex- 

 tending down the sides; the mesothorax is armed dorsally with four 

 narrowly separated chitinous plates which are without markings, 

 but are armed with long sets (Fig. 7) ; on each side of the body 

 there is a somewhat triangular plate; the metathorax is armed above 

 with four smaller dorsal plates and a single plate on each side of 

 the body (Fig. 7) ; on the sides the chitin of the dorsum of the 

 prothorax extends to the base of the front legs; on the outside of 

 each mesothoracic coxa there is a triangular piece of heavy chitin 

 which bears a tuft of long black sets on its front and on its ventral 

 corners; the metathorax bears similar chitinous pieces, each of which 

 has a single line of long black sets around its cephalic corner and 

 a line of similar sets extending from a point on its cephalic margin 

 well above its ventral corner to a point on its venter considerably 

 below the limits of the chitinous triangle; the venter of the thoracic 

 segments is without heavy chitin. The legs (Figs. 7 and 14) are 

 all armed with powerful curved claws, the form and distribution of 

 sets is shown in the accompanying figures, the apical membranous
