Color. — Head and pronotum dark coppery bronze with a light 

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

 the other setae brown. 



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

 of ocellus 2 equal to the distance between ocelli 1 and 2; fronto- 

 clypeo-labral area wider than long; U-shaped ridge on caudal part 

 of frons bearing two setae; antenna with the proximal and second 

 segments sub-equal in length, the third three-fourths and the distal 

 one-half the length of the second, the proximal segment with 9 

 or 10 setae and the second with 7 or 8; 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, proximal 

 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 al- 

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

 primary setae medium in size and prominent, secondary setae small 

 and not numerous (fig. 63). 



^ &</ome7i.— Chitinized areas distinct, secondary setae very short, 

 small and not numerous (fig.lOO) ; ninth abdominal sternum with 

 the caudal margin bearing two groups of four setae each; median 

 hooks with one seta, if two are present one is much smaller than 

 the other; inner hooks with two setae, the spine-like projection about 

 one-sixth the length of the hook (fig. 130). 



Bledsurements. — Length of larva, 16 to 18 mm., width at the third 

 abdominal segment, 2 to 2.2 mm. ; diameter of ocellus 2, 0.26 to 0.28 

 mm. ; distance between ocelli 1 and 2, 0.26 to 0,28 mm. ; length of 

 fronto-clypeo-labral area, 1.50 to 1.60, width, 1.60 to 1.70 mm.; 

 length of pronotum, 1.7 to 1.9 mm., width, 2.7 to 3 mm. 



The larvae of this species are found in a greater variety of habi- 

 tats than many of the other species of Cicindela. They have been 

 collected from wet, sandy soil, wet muddy soil, moist clay, and soil 

 with considerable humus. In general, however, they are found in
