Plate XXXIX. Figures 43-45. Plate XL. Figure 41. 



Surface of body smooth. Color yellow, with odd shaped markings 

 of black. 



Head narrower than first thoracic segment, with lateral margins 

 rounded, entire. Frontal margin straight, antero-lateral angles not 

 produced, rounded. Eyes large, with many ocelli, and situated on 

 the lateral margins of the head. 



The first pair of antenna? have the basal segment of the peduncle 

 enlarged, the next two segments successively narrower, all about 

 equal in length ; the flagellum is multi-articulate, composed of about 

 fourteen joints. The second pair of antenna:; have a scale-like 

 appendage outside of the third joint ; the fourth and fifth joints are 

 long, the fifth a little longer than the fourth ; the fiagellum is much 

 longer than the body, and is composed of about one hundred joints. 



The first thoracic segment is wider than the head ; the lateral 

 margins are straight, entire. The second and third segments have 

 the lateral margins excavate, the anterior and posterior angles pro- 

 duced, with the epimeron situated in the excavation. The fourth 

 segment has the anterior angle produced, the epimeron being situ- 

 ated in the excavation of the entire posterior part of the segment. 

 The fifth, sixth and seventh segments have the lateral margins entire, 

 the epimeron showing at the posterior part of the segment.
