margine haud serrulate ; pectore opaco sparsissime piloso, ventre 

 nitido. Long. 13 mm. ^ . 



Hah. Durango {Flohr). One example. 



A small species of the obsoleta group, resembling much 

 the typical form of C. obsoleta, with which it agrees in 

 colour, form of labrum, and sculpture of elytra. It 

 differs in the rather more prominent eyes and the 

 narrower and more rounded thorax. 



Cicindela viatica, Chevr. 



Var. nigrilabris. Sericeo-nigra elytris lateribus corporeqne 

 subtus cum femoribus interdum leviter cyaneo-tinctis ; labro in 5 

 semper nigro, in (J albo interdum nigro maculis duabus albis, raro 

 fusco-nigro. Long. 10-12 mm. 



Agrees precisely with the silky green or greenish blue 

 type-form in all respects, except in the black colour of 

 the body and the labrum of the ? . The eyes seem, 

 however, to be somewhat less prominent ; the peculiar 

 sculpture of the elytra is the same, viz., large but 

 shallow punctures in one or two slight longitudinal 

 depressions, and a rather close punctuation towards 

 the apex ; the smooth apical edge of the elytra, the 

 glabrous under surface, and the longitudinally convex 

 labrum, much produced in the middle and tridentate, 

 less strongly in <? than in ? , with lateral teeth short 

 and broad, are also the same. The palpi are black in 

 both sexes, much shorter in C. viatica and its variety 

 than in the other species of the genus, without, however, 

 any dilatation of the penultimate joint of the labials. 



Hah. Refugio in Durango (Hoge). A good series of 

 examples.
