length of fronto-clypeo-labral area, 1.55 to 1.65 mm., width, 1.55 to 

 1.65 mm.; length of pronotum, 1.7 to 1.9 mm., width, 2.8 to 3 mm. 

 This species is easily distinguished by the large number of setae 

 on the inner hooks. The larvae were collected at Galveston, Texas, 

 on Denver Beach, a short distance back from the shore line in sandy 

 soil with scattered vegetation, the larvae occuring in the open places. 

 The holes were from 9 to 10 inches deep.

 Figs. 74, 111, aud 141. 

 Shelford, not reared, larvae in the collection of the University of Illinois. 



Color. — Head and pronotum chestnut brown with a color patten- 

 of lighter areas; setae on dorsal aspect of head and pronotum trans- 

 parent to white, the other setae brown. 



Head. — Setae on dorsal aspect long, stout, and prominent; diam- 

 eter of ocellus 2 distinctly less than the distance between ocelli 1 and 

 2; fronto-clypeo-labral area as long as broad; U-shaped ridge on 

 caudal part of f rons bearing three setae ; antenna with the proximal 

 segment slightly shorter than the second, the third one-half and the 

 distal one-fourth the length of the second, the proximal segment 

 with five or six setae and the second with nine or ten ; maxilla with 

 the proximal segment of the galea bearing four setae on the mesal 

 margin, maxillary palpus three-segmented; ligula with four fine 

 setae arranged in a transverse row at the ventro-distal end, proximal 

 segment of labial palpus with two spine-like projections on the 

 ventro-distal margin and with three setae on the mesal side and two 

 on the lateral side of these spines, the proximal segment with five 

 setae and the distal segment with one. 



Thorax. — Pronotum with the cephalo-lateral angles extending al- 

 most as far cephalad as the mesal portion, lateral margins carinate, 

 primary setae not large or prominent, setae 5 and 6 wanting, second- 

 ary setae wanting (fig. 74). 



Ahdomen. — Chitinized areas distinct, secondary setae about one- 

 half the length of the primary setae, fine and not numeous (fig. 

 Ill) ; ninth abdominal sternum with the caudal margin bearing 

 two groups of four setae each; median hooks with two setae; inner 

 hooks with four setae, the spinelike projection one-third the length 

 of the hook (fig. 141). 



Measurements. — Length of the larvae, 24 to 26 mm., width at the 

 third abdominal segment, 3.4 to 3.6 mm. ; diameter of ocellus 2, 0.33 

 to 0.34 mm. ; distance between ocelli 1 and 2, 0.39 to 0.40 mm. ; length 

 of fronto-clypeo-labral area, 2.5 to 2.6 mm., width, 2.5 to 2.6 mm.; 

 length of pronotum, 2.9 to 3 mm., width 4.2 to 4.5 mm.
