Setae. — Long, whitish, either capitate or pointed, present in a rather 

 limited number on the back and sides of the larva. 



Head eaysule. — With slight depression in frons. 



Lahi^m. — About twice as wide as long, with entire front margin 

 regularly arcuate without emargination in the middle; discal setae 

 moderately long and pointed, marginal setae minute. 



Mandible. — With second, third, and fourth teeth large and claw

 same length; galea with many spinelike setae and a well-developed 

 tactile cone.

 forward. 



Prothorax (fig. 6). — Prothoracic shield with five marginal setae 

 anteriorly, one laterally, and two posteriorly. Epipleural sclerite 

 large, with two setae. Prehypopleural and posthypopleural sclerites 

 (=episternum and epimeron) well developed and of the same size. 

 Eusternal and sternellar sclerites almost fused to one plate, with 

 two setae on each side. 



Mesothorax and metathorax. — Having all the sclerites of moder- 

 ate size; compound middorsal sclerites separated sagitally by a fine, 

 white suture. Prescutal area with interior compound sclerite car-

 prescutal sclerite distinct, one seta. Compound interior scuto-scutel- 

 lar sclerite narrower than the interior prescutal sclerite, one seta on 

 each side; exterior scuto-scutellar sclerite nearer the middle line 

 than the exterior prescutal, one seta. Parascutal area with no ante- 

 rior sclerite, a distinct posterior sclerite with one seta, and no dis-
