CICINDELID.E AND CARABID^: 9 



13 Tranquebarica group. 



In this group the humeral lunule becomes greatly inflexed and 

 posteriorly oblique, most of the other characters being as in the 

 two preceding groups. It includes four evident subgroups, typified 

 by the four very isolated species tranquebarica, hyperborea, diffracta 

 and plutonica. The species and subspecies are tranquebarica 

 Herbst (vulgaris Say and obliquata Dej.), kirbyi Lee. (obliquata 

 Kirby), vibex G. H. Horn (? roguensis E. D. Harris), diffracta and 

 plutonica Csy., horiconensis and bellissima Leng and viridissima 

 Fall; also turbulenta* and crinifrons*. Sierra Leng belongs to the 

 purpurea group; it is an isolated and valid species and not by any 

 means a variety of anything. 



14 Repanda group. 



This is a very large group, characterized by a smaller and shorter 

 body than in the three preceding and a humeral lunule which is 

 only moderately inflexed posteriorly and to nearly similar a degree 

 as at base, most frequently resolved into two dots; the sculpture, 

 pubescence and other characters are nearly as in the preceding. 

 The various forms are repanda and duodecimguttata Dej., oregona 

 Lee., ancocisconensis Harris, unijuncta, depressula and scapularis 

 Csy., eureka Fall and maricopa Leng, as well as bucolica*, sterope*, 

 quadripennis* , ovalipennis* , sonoma*, and audax*. Depressula and 

 scapularis form a well characterized subgroup in having the elytra 

 more oblong, less convex, more coarsely punctured and of a vivid 

 green that does not appear in any other forms. Ancocisconensis 

 was made the type of a separate group, far removed from repanda, 

 by Leng, but I cannot appreciate the reasons for this disassociation. 

 Unijuncta is much smaller and narrower than repanda, in addition 

 to the different form of maculation, and I have little or no doubt 

 now that it is a distinct species; it has probably not been correctly 

 identified by Mr. Leng. 



15 Hirticollis group. 



The habitus here is rather different from repanda and allies, owing 

 to the more inflated body and, more especially, because the humeral 

 lunule has a distinctly different form, the posterior inflexed part 

 being much longer, straight and transverse to somewhat anteriorly
