ClCINDELID/E AND CARABID/E 21 



but larger, only feebly convex, white, with a sutural dark vitta which is 

 broad at base, becoming gradually narrower and extinct at apical fourth 

 or fifth, the white field having on each a single feebly arcuate dark line 

 near outer third behind the middle, oblique in direction but wholly 

 without trace of other dark maculation; tarsi very short. Length (c? 1 9 ) 

 10.5-11.3 mm.; width 4.0-4.4 mm. Canada (Aweme, Manitoba), 

 Griddle. 



Differs from limbigera in its larger size, aeneous-brown color 

 more greenish beneath and in the constant absence of the dark 

 sublateral spot before the middle, which is as constantly present in 

 that species. 



ii In the purpurea group there are many rather distinctly 

 characterized species and subspecies not as yet recorded in the 

 literature; some of these are as follows: 



Cicindela purpurea ssp. auguralis nov. Larger and with more elongate 

 hind body than in purpurea, obscure green with cupreous side margins 

 to brownish-cupreous suffused with greenish; elytral markings, when 

 complete, consisting of an entire humeral lunule, a middle band some- 

 times expanded at the margin and a complete apical lunule, but generally 

 with the humeral and apical lunules divided broadly. Length (cf 9 ) 

 13.0-15.0 mm.; width 5.2-5.5 mm. Colorado. 



The greener examples of this subspecies have been confused with 

 graminea in most collections. Graminea is a much narrower and 

 more elongate form, with less transverse prothorax, pure green 

 above, with brighter green or blue metallic side margins; it is much 

 more deficient in basal maculation, only one of my three examples 

 having even so much as a single humeral spot. From purpurea it 

 differs in its larger size, more elongate elytra and much more com- 

 plete basal maculation of the elytra, though the coloration, in the 

 prevalence of brownish-coppery shades, is similar. 



Cicindela purpurea ssp. ardelio nov. Smaller and much narrower 

 than purpurea, the elytra more elongate; color dark and obscure uni- 

 form green above, with simply slightly paler and more shining and nar- 

 rower side margins, very dark blue beneath; elytral maculation complete, 

 consisting of an entire humeral lunule, an apical lunule complete, except 

 that the outer end is detached as a discal spot, and a middle band only 

 very feebly oblique at its inner end and much expanded along the side 

 margins. Length (cf ) 12.5 mm.; width 4.7 mm.; New Mexico. 



I would have considered this to be graminea, were it not for the 

 still narrower form of the body and the fuller elytral maculation,
