 Shelford, reared, larvse in the collection of the University of Illinois. 



Color. — Head and pronotum dark purple with a blue reflection, 

 setae on dorsal aspect of head and pronotum transparent or glassy, 

 the other setae brown. 



Head. — Setae on dorsal aspect long, slender and not conspicuous ; 

 diameter of ocellus 2 distinctly greater than the distance between 

 ocelli 1 and 2; fronto-clypeo-labral area as long as broad; U-shaped 

 ridge on caudal part of frons bearing two setae; antenna with the 

 proximal segment subequal in length to the second, the third slightly 

 more than one-half and the distal one-fourth the length of the second, 

 the proximal segment with seven or eight setae and the distal with 

 10 or 11; maxilla with the proximal segment of the galea bearing 

 three setae on its mesal margin, maxillary palpus three-segmented: 

 ligula with four fine setae arranged in a transverse row at its ventro- 

 distal end, proximal segment of labial palpus with three spine-like 

 projections on the ventro-distal margin and with two setae on each 

 side of these spines, the proximal segment with four setae and the 

 distal segment with one. 



Thorax. — Pronotum with the mesal portion extending distinctly' 

 cephalad of the cephalo-lateral angles, lateral margins carinate, 

 primary setae small and inconspicuous, secondary setae minute and 

 numerous (fig. 65). 



Abdomen. — Chitinized areas on abdomen indistinct, secondary 

 setae short, fine, and numerous (fig. 102) ; ninth abdominal sternum 

 with the caudal margin bearing two groups of three setae each; 

 median hooks with three setae; inner hooks with two setae; the 

 spinelike projection about one-sixth the length of the hook (fig. 132). 



Measurements. — Length of larvae, 17 to 19 mm., width at the third 

 abdominal segment, 2 to 2.3 mm. : diameter of ocellus 2, 0.30 to 0.33 

 mm.; distance between ocelli 1 and 2, 0.17 to 0.18 mm.; length of 

 fronto-clypeo-labral area, 1.35 to 1.40 mm. ; width, 1.35 to 1.40 mm. ; 

 length of pronotum, 1.5 to 1.7 mm. ; width, 2.3 to 2.5 mm. 



The larvae of this species were collected at Mobile, Ala., in a 

 sandy, dry stream bed and other sandy situations. The soil was 

 sandy and had sufficient clay in it to make it mold well. The larval 

 burrows were vertical and from 22 to 44 inches deep.
