26 MEMOIRS ON THE COLEOPTERA 



of the edge as is generally the case in that species; front coarsely, strongly 

 pubescent; prothorax very large, wider than the head, nearly similar 

 but more transverse; elytra broader but with similar markings; under 

 surface similar but more pubescent at the sides. Length (9 ) 16.0 mm. 

 width 6.5 mm. Mississippi (Vicksburg). 



Readily distinguishable by its large size, broad form and very large 

 prothorax. 



Cicindela crinifrons n. sp. Smaller and more convex than tranque- 

 barica, dull and still blacker in color above, the under surface as in that 

 species; front densely hispido-pubescent, even more densely in the female, 

 the hairs fine; prothorax, like the head, paler brown, a lateral streak and 

 the sulci blue; elytra one-half (cf ) to one-third ( 9 ) longer than wide, the 

 sculpture and ornamentation nearly similar, except that all the white 

 markings are generally finer and that the humeral lunule is much less 

 oblique posteriorly, ending at about the median line of each elytron at 

 and not behind basal third; under surface more pubescent laterally. 

 Length (cf 9 ) 11.0-13.0 mm.; width 4.7-5.7 mm. North Carolina 

 (Asheville and Southern Pines). 



This form differs so much from tranquebarica in size, convexity, 

 in its blacker color, more abundant pubescence and in the direction 

 and extent of the posterior part of the humeral lunule, that I prefer 

 to give it a specific status. 



On reading Dejean's description of obliquata very carefully, it 

 becomes evident that obliquata Dej., is merely the species named 

 tranquebarica by Herbst and vulgaris by Say. This was recognized 

 also by LeConte, who gave the name kirbyi to the obliquata of 

 Dejean as understood by Kirby. The species should therefore be: 



Cicindela kirbyi Lee. Obliquata Kirby nee. Dej. (Faun. Bor. Am., iv, 

 10) Narrower, more elongate, more convex and paler coppery-brown 

 than tranquebarica Hbst., and with the elytral markings much broader 

 though otherwise as in that species, except that the oblique part of the 

 middle band is more extended posteriorly. Colorado to Manitoba 

 (Aweme). 



The northern specimens are a little smaller than the southern as a 

 rule, but do not differ otherwise, and there are two examples from 

 Colorado before me, in which the elytra are broader and more in- 

 flated than in any others of a good series. There are a good many 

 varieties near vibex and kirbyi, but my material is not sufficient to 

 differentiate them.
