REVISION OF ELEODIINI BLAISDELL. 151 



The prontal margin is usually obsolete and the sides of the pro- 

 notal disc are continuously convex with the flanks. Ordinarily, the 

 margin is finely crenulate. In one specimen the margin is distinctly 

 developed in the anterior two-thirds of the pronotum. where it is 

 acute and minutely reflexed. 



In the LeConte collection along with the type there is placed a male 

 and female, without locality labels and of peculiar form as follows : 

 The elytra are sculptured as in yrunosa, the thorax is very opaque 

 with rather close, coarse, and shallow punctures, as if the rugosities 

 seen in the type of granosa had been worn down. The thorax is 

 much broader, with the anterior angles more prominent, the sides 

 slightly sinuate behind ; eh'tra not qinte so convex, more elongate 

 and more attenuate posteriorly. The foregoing applies to the female 

 as compared with the female of granosa. 



The male has distinctly longer antenna?, joints four to eight in- 

 clusive being longer; elytra but little wider at middle than the pro- 

 thorax and consequently appear more convex: the anterior and mid- 

 dle tibia^ scarcely differ from those of the female. The side margin 

 of the pronotum is feebly defined anteriorly and obsolete posteriorly. 



I am indebetd to Mr. Blanchard for the above notes, and as I have 

 not seen the specimens I can only surmise that they may be a race of 

 granosa. A Coso Valley specimen is more elongate than any other of 

 the specimens before me and it is decidedly less convex, the elytra 

 being somewhat flattened on the dorsum. In one or two specimens 

 the elytra are slighth^ ventricose. 



Specimens recently collected by Mr. F. W. Xunenmacher at (lold- 

 fields. Nevada, are deep black and shining, the scidpturing coarse as 

 in the Panamint Valley specimens above referred to. 



The mentum exhibits considerable variation, being moderate in size, 

 triangular or subparabolic in outline, convex at middle and exca- 

 vated laterally. The prosternum is more or less evenly convex antero- 

 posteriorly between the coxa\ fivc^ueutly grooved; mucronate behind, 

 the mucro moderate, conical or triangular. 



Mesosternum short, very obliiiue. aiul broadly concave. 



The external borders of the anterior tibia? are distinctly carinate 

 nearly to the apex, and the middle and posterior tibia^ to a greater 

 or less extent as well. 



The tibial grooves of the femora are well defined, the margins are 

 subasperateh' punctate and the floor of each is more or less i)unctate 

 and opaque. 



The anterior tarsi are subequal in stoutness and length in the sexes.
