22 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.65. 



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

 and inconspicuous (fig. 161) ; ninth abdominal sternvnn with the 

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

 with three setae; inner hooks with 8 to 10 setae, the spine-like projec- 

 tion not more than one-sixth the length of the hook (fig. 173). 



Measurements. — Length of larva, 18 mm.; width at the third 

 abdominal segment about 2 mm. ; diameter of ocellus 2, 0.45 mm. ; 

 distance between ocelli 1 and 2, 0.30 mm.; length of fronto-clypeo- 

 labral area, 1.6 mm. ; width, 1.6 mm. ; length of pronotum, 1.6 nun. ; 

 width, 2.7 mm. 



The larva of this species is from India and was collected by Walter 

 Horn. The nearest American form that I have studied is Clcindela 

 dorsalis saulcyi and in many respects the two are quite similar. 

 Cicindela hiramosa is the larger of the two species and may be 

 separated from Cicindela dorsalis saadcyi by the two setae on the 

 U-shaped ridge, the ninth abdominal sternum bearing two groups 

 of four instead of three setae each, the median hooks with three setae 

 and the inner hooks with 8 to 10 setae.

Color. — Head dark purplish brown, pronotum brown with a color 

 pattern of lighter areas ; setae on head and pronotum white, the other 

 setae brown. 



Head. — Setae or dorsal aspect medium in length and prominent; 

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

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

 on the caudal part of frons bearing two setae; antenna with the 

 proximal segment slightly shorter than the second, the third two- 

 thirds and the fourth one-half the length of the second, the proximal 

 segment with nine or ten setae and the second with eight or nine; 

 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 not cari-
