This species is a European form and may be distinguished from 

 its nearest forms by the four distinct setae on the median hooks, the 

 number of setae on the pronotum, and the shape of the inner hooks.

 Horn, W., reared, larvae in the collection of the University of Illinois. 



Color. — Head and pronotum bright coppery bronze with a green 

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

 other setae transparent or brown. 



Head. — Setae on dorsal aspect short and not conspicuous ; diameter 

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

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

 part of frons bearing three or more setae; antenna with the proximal 

 segment slightly shorter than the second, the third two-thirds and the 

 fourth slightly less than one-half the length of the second, the proxi- 

 mal and second segments each with twelve to fourteen 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 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. 



Tliorax. — Pronotum with the cephalo-lateral angles extending as 

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

 primary setae slightly longer than the secondary setae and not con- 

 spicuous, secondary setae short, conspicuous, slightly flattened and 

 numerous (fig. 155). 



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

 and inconspicuous (fig. 167) ; 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 spine-like 

 projection about one-third the length of the hook (fig. 176). 



Measurements. — Length of larvae, 15 to 18 mm. ; width at the 

 third abdominal segment, 1.7 to 2 mm.; diameter of ocellus 2, 0.29 

 to 0.31 mm. ; distance between ocelli 1 and 2, 0.29 to 0.31 mm. ; 

 length of fronto-clypeo-labral area, 1.7 to 1.8 mm.; width, 1.9 to 

 2.1 mm.; length of pronotum, 2 to 2.1 mm.; width, 3.2 to 3.6 mm. 



This is an European species and is given as a variety of Cicindela 

 hyhrida. It may be separated from the preceding by the larger 

 number of setae on the proximal and second segments of the antennae 

 and by the larger number of setae on the pronotum, also by the
