Mature larva (figs. 4, 5). — About 12 mm. long. 



Head shining black with black labriim; frontal sutures fine whitish 

 lines; body somewhat varying in color, generally dull yellow, with a

 lighter on the inner side.^* 



Setae moderately long and moderately strong, pointed and yellow- 

 ish; present in considerable number on the back and the sides of 

 the larva. 



Head capsule (fig. 38). — With a large unpaired depression in the 

 middle of frons posterior to epistomal margin. 



Labrum. — Subrectangular, about twice as wide as long, with front 

 margin slightly emarginate medianly. Discal setae somewhat longer 

 than labrum itself ; marginal setae short and fine. 



Mandible (fig. 46). — With four teeth, the second of which being 

 the larger and more extended; inner margin of mandible immedi-

 carrying six setae. Prehypopleural sclerite (= episternum) light 

 colored with about four setae; posthypopleural sclerite (= epimeron)
