Figs. 151, 163, and 175. 



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

 and the author's collection. 



Color. — Head and pronotiim coppery bronze with a light bhie 

 reflection; setae on dorsal aspect of head and pronotum white, the 

 other setae brown. 



Head. — Setae on dorsal aspect long and prominent; diameter of 

 ocellus 2 equal to the distance between ocelli 1 and 2 ; f ronto-clypeo- 

 labral area as long as wide; U-shaped ridge on caudal part of frons 

 bearing two setae; antenna with the proximal segment slightly 

 shorter than the second, the third two-thirds and the distal one- 

 half the length of the second, the proximal segment with ten to 

 twelve setae and the second with six to eight; maxilla with the proxi- 

 mal segment of the galea bearing three setae on its mesal margin, 

 maxillary palpus three-segmented; ligula with four fine setae. ar- 

 ranged in a transverse row at its ventro-distal end, proximal seg- 

 ment of the labial palpus with three spinelike 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 cephalo-lateral margins extending 

 as far cephalad as the mesal portion, lateral margins slightly cari- 

 nate, primary setae medium in size and prominent, secondary setae 

 about 10 in number, moderate size (fig. 151). 



Abdomen. — Chitinized areas distinct; secondary setae short, fine 

 and not numerous (fig. 163) ; ninth abdominal sternum with the 

 caudal margin bearing two groups of three setae each ; median hooks 

 with one seta; inner hooks with two setae, the spine-like projection 

 one-third the length of the hook (fig. 175). 



Measurements. — Length of larvae, 16 to 18 mm., width at the 

 third abdominal segment, 2 to 2.5 mm. ; diameter of ocellus 2, 0.30 

 to 0.32 mm.; distance between ocelli 1 and 2, 0.30 to 0.32 mm.; 

 length of fronto-clypeo-labral area, 1.65 to 1.75 mm., width, 1.65 

 to 1.75 mm.; length of pronotum, 1.75 to 1.85 mm., width, 2.85 to 

 3 mm. 



The larvae were collected at Pines, Indiana, by the author together 

 with Cicindela hirticollis. They were also found with two undated 

 collections of larvae of Cicindela hirticollis.
