26G OEO. ri. HORN, m. d. 



a smooth line starting from the end of each basal impression and 

 convergintc forward, this line is devoid of punctures and is deBned by 

 the punctures on each side of it being rather more closely placed. 

 In color, and considerably in form, this species resembles nehras/cennin, 

 but the thorax of the latter is so much more coarsely and densely 

 punctured and the surface shining. Mr. Ulke has a variety with the 

 elytra bluish. 



One specimen 9 , collected by Belfrage, in Waco County, Texas. 



23. C obsolctus, Lee. — Body beneath black, legs pale. Head blue, 

 shining, minutely punctuiate, labruin einarginate, antennae rufous, paler at 

 base. Thorax slightly broader than long, base very little broader than apex, 

 sides arcuate in front, moderately deeply sinuate posteriorly, hind angles 

 slightly obtuse, surface subopaque, bluish, with sparsely placed, rather coarse 

 but vague punctures, sparsely pubescent. Elytra with fine striae not visibly 

 punctured except near the base, intervals flat, sparsely and finely puucturid. 

 Body beneath as in va/er. Length .42 inch; 10.5 mm. 



Chaudoir is undoubtedly correct in recognizing this as a distinct 

 species, as Dr. Leconte himself did in the first instance. 



Occurs principally in the southern portions of California, but speci- 

 mens have occurred as far north as Mariposa. 



24. C solitarius. Say. — Above bright green, moderately shining. Lab- 

 rum truncate. Antennae with third joint longer. Thorax slightly longer than 

 wide, base and apex equal, sides moderately strongly arcuate in front, sinuate 

 behind, hind angles rectangular slightly obtuse, surface rather sparsely punc- 

 tured along the base, median line and apical impression. Basal line uf elytra 

 arcuate at humeri, striae moderately impressed, |)unctured, intervals flat, sparsely 

 punctuiate and pubescent. Prosternum with feeble trace of marginal line at 

 tip, in front very sparsely punctured, side pieces with few punctures. Mcta- 

 sternal episterna feebly margined, more strongly in front, sparsely punctured. 

 Abdomen sparsely punctured and pubescent at the sides, smooth at middle, 

 last segment margined with testaceous. Legs pale. Length .43 — .56 inch; 

 12—14 mm. 



In the male the anterior femora are distinctly subangulate at b.'.sal 

 third. 



This is the only species in our fauna in which the elytra when 

 deprived of pubescence are as shining as the thorax. 



Occurs from Canada to Louisiana, Colorado and New Mexico. 



25. C". leiK'OMOelis, Chevr. — Dark violet blue. Labrum truncate. Thorax 

 as in solitarius, subopaque, sj)arsely punctured along the base, median line and 

 in front, basal impressions long, arcuate. Eiytral intervals moderately densely 

 and finely punctuiate, sparsely pubescent. Prosternum not margined at tip, 

 in front smooth, episterna obsoletely punctured. Abdomen as in soliturius, last 

 segment paler along the margin. Length .50 — .60 inch; 12.5—15 mm. 



Male with anterior femora subangulate at base.
