(7) 7. * Cicindela albilabris. White-lipped Cichulela. 



C. I albilabris) labro albo obsolete tridentato, medio prominulo ; supra purpurascenti-nigra : elytris excavato-punctatis : quttis 

 tribus marginalibus fasciaque fracta discoidali, albis. 



White-lipped Cicindela, with the labrum white, obsoletely tridendate, rather prominent in the middle ; elytra broadly punc- 

 tured with three marginal dots and a broken discoidal band, all white.

Length of the body 6 — 6i lines. 



Taken in Lat. 64°, and also in Canada by Dr. Bigsby. 



DESCRIPTION. 



c? 



Body underneath green or golden-green clouded with blue ; above black with a purplish tint : 

 labrum white, prominent, armed in the middle with three short teeth, the lateral ones obtuse; above 

 with an intermediate obtuse longitudinal ridge : elytra, under a powerful magnifier, covered with 

 innumerable minute granules, and also with numerous shallow impressions, a series of larger ones is 

 parallel with the suture ; the angular white discoidal band reaches neither the suture nor the lateral 

 margin ; there are also three marginal white dots, one humeral, another between it and the band, and 

 one between the latter and the apex. 



Variety. B. S. Body underneath blue, anus green; above black with the spots of the elytra 

 buff-coloured. 



C. <S . Body underneath as in B: elytra with only two marginal dots, the band and 



apical dot almost obliterated, the humeral dot distinct. 



D. ?. Body underneath blue with a black anus: elytra with no marginal white dots; 



band replaced by a faint streak and dot. Plate I. Fig. 1. ?. 

 This species, though apparently common in North America, is not noticed by Say, who perhaps 

 mistook it for C. sylvatica Linn, of which it may be regarded as the American representative, and 

 with which it agrees in its prominent upper lip, and the shallow impressions and markings of its 

 elytra, as well as nearly in its general colour. But besides its smaller size, it differs from it mate- 

 rially in having a white instead of a black upper lip with an obtuse longitudinal ridge and not an 

 acute one, terminating in three almost obsolete short teeth instead of a single longer one; and 

 likewise by the want of the silky lustre produced by granulations much more visible, which distin- 

 guishes the elytra of C. sylvatica.
