of fronto-clypeo-labral area, 1.60 to 1.70 mm., width, 1.70 to 1.80 

 mm.; length of pronotum, 1.90 to 2.10 mm., width, 3 to 3.3 mm. 



The life history of this species has not been definitely determined, 

 but field observations would seem to indicate that it is similar to 

 Cicindela repanda. The larvae are usually found in clay or humus. 

 Criddle (1907) found the larvae burrowing in large numbers along 

 the banks of a river at Awene, Manitoba, in clayey, muddy, and 

 sandy soil. In the summer time the burrows are from 4 to 5 inches 

 deep and in the winter time from 6 to 15 inches. The holes gener- 

 ally slant obliquely into the bank.

Reitter, E., two larvae in the collection of the U. S. National Museum. 

 Bought from and determined by E. Reitter, 1922. 



Color. — Head and pronotum brownish bronze with a faint green 

 reflection ; setae on dorsal aspect of head and pronotum transparent, 

 the other setae brown. 



Head. — Setae on dorsal aspect short, fine, and inconspicuous; 

 diameter of ocellus 2 subequal to the distance between ocelli 1 and 

 2; fronto-clypeo-labral area subequal in length and width; U-shaped 

 ridge on caudal part of frons, bearing two fine inconspicuous setae; 

 antenna with the proximal and second segments subequal in length, 

 the third three-fourths and the fourth slightly more than one-half 

 the length of the second, the proximal and second segments each 

 with five or six setae; maxilla with the proximal segment of the 

 galea bearing three setae on its mesal margin, maxillary palpus 

 three-segmented ; ligula with four fine setae on the ventro-distal end 

 arranged in a transverse row, proximal segment of labial palpus 

 with three spinelike projections on the ventro-distal end 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 

 almost as far cephalad as the cephalo-mesal portion, lateral margins 

 slightly carinate; primary setae not large or prominent; secondaiy 

 setae short, few and inconspicuous (fig. 160). 



Ahdomen. — Chitinized areas indistinct; secondary setae few, fine, 

 and inconspicuous (fig. 171) ; 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 setae on the outer 

 side of the hook nearer the tip than the one on the inner side, spine- 

 like projection about one-third the length of the hook (fig. 181). 



Measurements. — Length of larvae, 15 to 17 mm.; width at the 

 third abdominal segment. 1.5 to 2 mm.; diameter of ocellus 2, 0.18 to
