from base to apex. First joint of the anterior tarsi set with ordinary 

 spinules on tip beneath. 



Measurements. — Males: Length, 1G.5 mm.; width, 6.5 mm. 

 Females: Length, 18.3-19 mm.; width, 8-8.5 mm. 



Genital characters. — Male characters as in earhonaria. 



Female. — As in earhonaria., except that the dorsal plate of each 

 valve is narrower, with the sides more parallel and less explanate 

 externally; the outer lobe of the apex is less broadly rounded. 



Habitat. — Texas (Eagle Pass and San Antonio, LeConte; Browns- 

 ville, Wickham.) 



Number of specimens studied, 8. 



Type, a female in the LeConte collection. 



Type-locality. — Eagle Pass; Texas. 



Salient type-charactei'x. — Thorax quadrate, slightly narrowed an- 

 teriorly and posteriorly ; sides broadly rounded; anterior angles acute, 

 the posterior obtuse. Elytra strongly striato-punctate, intervals 

 .sparsely punctate (LeConte). 



Diagnostic characters. — On ac(M«it of the form of the prothorax 

 it somewhat resembles a smooth goryi., and LeConte differentiated 

 it from that species as follows: "The thorax is more quadrate and 

 not more narroAved towards the apex than towards the base; the 

 elytra are more deeply emarginate at base, and transversely much 

 less convex, and those of the female are much less dilated; the punc- 

 tures are more regular and never have the appearance of fovea?." 



All the specimens that I have received have either been labeled 

 goryi or unidentified, and it is undoubtedly confused with that spe- 

 cies in collections generally. Tn all cases of doubt the subgeneric 

 and genital characters must be carefully studied. 



The sciiplturing of Hopor is quite like that of a typical carhoiuuia., 

 except that the serial punctures on the dorsum of the elytra are 

 smaller, although as large or slightly larger and more distinctly de- 

 fined laterally, the surface is feebly duller, the pronotum more quad- 

 rale on account of the strongly deflexed sides of the (Hm- and conse- 

 quently less strongly I'ounded when viewed from above, and usually 

 not more narrowed toward the apex than the base, but this character 

 may be va liable. 



The actual form of the pronotal margin in both sexes is like that 

 of a male <-(irl)oii(iria, Avidest at the middle and not noticeably more 

 strongly arcuate in the anterior moiety, as in the female of car- 

 honarhi. 



From the members of the qnadricolUs section of the present sub- 

 genus it is to be known by the form of the anterior spurs of the 

 anterior tibiae 



I am indebted to Professor Wickham for the specimens in my 

 collection.
