The life history of this species as given by Shelford (1908) differs 

 from that of other species in that the adults do not hibernate and 

 there is only a single year required for the life cycle. The eggs are 

 laid in relatively hard, dry soil, usually humus, the latter part of 

 July, and larvae were dug from bare spaces between clumps of grass 

 in the vacant lots of Chicago. The majority of the larvae are in the 

 third instar by September, in which instar they hibernate and ap- 

 pear early the next spring. They feed until April or early June, 

 when they pupate. The adults emerge in early July, mate and lay 

 eggs. The larval burrows during the feeding reason are from 12 to 

 16 inches deep but are slightly shallower in the summer just before 

 the larvae go into the pupal stage. This species was reared by Shel- 

 ford, 1905 and 1906 at Chicago, Illinois. Criddle (1907) states that 

 the larvae are found at Aweme, Manitoba, in small, mossy places be- 

 tween clumps of grass in dry situations. The depth of the holes 

 ranged from 18 to 26 inches. The adults do not hibernate and it is 

 probable that the larval stage lasts over two winters. 



I have collected adults and dug larvae of this species from moist, 

 adobe soil at Haswell, Colorado.

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



Color. — Head and pronotum purple or purplish bronze with a blue 

 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 greater than the distance between ocelli 1 and 2; fronto- 

 clypeo-labral area as long as broad; U-shaped ridge on the caudal 

 part of f rons bearing two setae ; antenna with the proximal segment 

 slightly shorter than the second, the third one-half and the fourth a 

 little more than one-third the length of the second, the proximal seg- 

 ment with five or six setae and the second with nine or ten ; 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, proxi- 

 mal 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 cephalo-lateral angles extending as 

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

 setae large and prominent, secondary setae small and not numerous 

 (fig. 70).
