ClCINDELIOE 33 



obtuse apical lobe, of which there is no trace in the female of lin- 

 colniana, the apex in the latter being almost exactly as in macro, 

 and even more distinctly acute than in sperata. 



In the punctulata group it would be better to regard boulderensis 

 as one of the subordinate forms of chihuahua; it has scarcely any 

 metallic coloration above however, being as in punctulata in that 

 respect, and it differs further in having the row of foveae, forming so 

 marked a feature in chihuahua, obsolescent and barely discoverable 

 behind basal fourth; the elytral punctures, however, are lustrously 

 burred as in that species. In the two following, which I believe 

 to be species, the elytral punctures are not burred. In chihuahua 

 the elytra vary from pale green with subcupreous reflection, to a 

 very deep and rich violaceous-blue; in boulderensis this becomes 

 blackish as in the following: 



Cicindela prolixa n. sp. Form very elongate, rather convex; color 

 blackish-brown, with faint subcuprous lustre above, shining and very 

 dark steel-blue beneath; pubescence throughout as in chihuahua; head 

 and labrum as in that species, the eyes rather more prominent and 

 the antennae a little longer; prothorax similar in general form and sculp- 

 ture but less abbreviated, being nearly as long as wide even in the female; 

 elytra very much more elongate and much less obtuse at apex, parallel, 

 feebly arcuate at the sides and not quite twice as wide as the prothorax, 

 being relatively much more slender than in chihuahua, the punctures 

 differing radically, being perforate, smaller in size, sparser and without 

 anterior burring, the row of foveae entire and conspicuous throughout, 

 the foveae bright green; maculation almost obsolete, the humeral lunule 

 represented by two small points, the transverse band by a small obsoles- 

 cent discal spot, the marginal spot at apical third not distinct and the 

 apical lunule very slender, reflexed anteriorly or not. Length ( 9 ) 

 12.0-13.5 mm.; width 4.1-4.35 mm. Colorado (Akron), -Shantz. 



The very narrow elongate hind body, even in the female, gives 

 this species a very different habitus from chihuahua and the pro- 

 longed apex and different sculpture also seem to point toward a 

 true specific status. 



Cicindela fontinaria n. sp. Outline very much as in chihuahua;, dark 

 cupreous-brown, the pronotal sulci blue, the elytra pale greenish, be- 

 coming brown internally and with a still darker brown streak along the 

 entire line of large and shallow, bright blue foveee; head nearly as in 

 chihuahuas, the labral tooth very feeble; prothorax small, slightly trans- 

 verse, much narrower than the head, minutely rugulose, shining and 

 punctured at the .sides, the sulci deep; elytra in form, sculpture and macu- 

 lation nearly as in chihuahua but with the elytral punctures scarcely 

 burred, more rapidly coarse and close laterally, and with an entire pale
