sandy situations around the margins of small ponds, lakes and 

 streams which have too much vegetation for Gicindela hirticoUis. 

 The larvae usually occur among the first rather rather scattered veg- 

 etation in such places. The burrows are about ten centimeters deep 

 and their general direction is at right angles to a sloping surface 

 and oblique to a horizontal surface. The eggs are laid in May and 

 June, and the larvae reach the third instar by fall, in which instar 

 they pass the winter. The adults emerge the following summer, 

 hibernate, and appear in May of the second year, reach sexual ma- 

 turity, lay their eggs and die. They are two years in their life 

 cycle.

Color. — Head and pronotum bronze, with a greenish-blue reflec- 

 tion; setae on dorsal aspect of head and pronotum transparent or 

 glassy, the other setae brown. 



Head.— Setae on dorsal aspect long, slender and prominent; di- 

 ameter of ocellus 2 distinctly greater than the distance between 

 ocelli 1 and 2; fronto-clypeo-labral area slightly broader than long; 

 U-shaped ridge on the caudal part of frons Avith 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 six or seven setae 

 and the second with nine or ten; maxilla with the proximal seg- 

 ment 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 the ventro-distal end, proximal segment of labial 

 palpus with two spine-like projections on the ventro-distal margin 

 and with two setae on each side of these spines, the proximal seg- 

 ment 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 not carinate, 

 primary setae not large or prominent, secondary setae small and 

 numerous (fig. 64). 



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

 third the length of the primary setae, fine and not numerous (fig. 

 101) ; ninth abdominal sternum with the caudal margin bearing 

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