Series B. 

 These species, by the subseriate elytral punctuation, approach 

 Euryscopa gradually by their sculpture and one of them might, by 

 that alone, be placed in Euryscopa. They are as follows : 



Elytra pubescent, the punctuation relatively fine and close. 

 Elytra with distinct humeral red spot 

 Tiiorax densely punctate, the punctures much closer than their own diam- 

 eters, the smooth median line well marked axillitris. 



Thorax quite sparsely punctate, at least anteriorly. 



Elytral punctuation distinctly subseriate, the pubesceiice of surface not 



dense Oiiiiella. 



Elytral punctuation very indistinctly substriate and only so at the sides, 

 pubescence of upper surface dense, almost concealing the surface color 



and sculpture iniicoreH. 



Elytra without humeral red spot, the smooth thoracic vitta indistinct. 



seiiescens. 

 Elytra glabrous, the i>unctures coarse, subseriate and closely resembling Eury- 

 scopa; no humeral spot seiieipeiiiiis. 



In the males of all. the species of this series the mandibles are not 

 subangulate externally, and are scarcely more prominent than in 

 the female. The last ventral of the male has a smooth space, the 

 female a smooth fovea. 



C. a.Y:illari<« Lee, Trans. Am. Ent. Soc. 1868, p. 56. — Form subcylindrical. 

 scarcely at all narrowed behind tlie humeri, piceous. slightly bronzed, moder- 

 ately shining, very sparsely pubescent, humeri with a quadrate red spot covering 

 the umbone. Head moderately densely, but not deeply pun(;tate; lahrum pi- 

 ceous, yellow at the sides; thorax regularly convex, hind angles distinct, sur- 

 face densely and equally punctate, the median smooth line well marked, except 

 sometimes in front; elytra densely punctate, more coarsely than the thorax, the 

 punctures distinctly subseriately placed, the apex somewhat smoother; body 

 beneath densely punctulate and pubescent; 'legs piceous, sparsely pubescent. 

 Length .14— .20 inch. ; .3..5 — 5 mm. 



There does not seem to be any notable variation among the speci- 

 mens studied. 



Occurs from Colorado to Texas. 



C raiiella Lee, Trans. Am. Ent. Soc. 1874, p. 25; bifaria Lee, loc. cit. 



Closely resembles axillaris, and differs in having the thorax not 

 closely punctate on the disc, the punctures more distantly separated 

 than their own diameters. In the majority of specimens tlie tibia^ 

 are reddish on the outer side. 



The typical specimens of the two species are before, and I am en- 

 tirely unable to perceive why two species should have l)een described. 



Occurs in southern California and Arizona.
