The individuals of eordata and phneUoklef^ vaiy greatly, and the 

 present race appears to be but a well-marked heterotype; this rela- 

 tion is quite clearly demonstrated in the large series before me. 



In examples of hrunnipes from Pocatello, Idaho, and which agree 

 quite Avell with the description, the setae are longer and more evident 

 throughout. 



Otlierwise as in pimelioidefi. 



ELEODES CASEYI, new species. 



OA^ate, about twice as long as wide, legs reddish-brown, distinctly 

 pubescent throughout. Pronotum rather coarsely, densely, and more 

 or less rugosely punctate ; elytra rather finely and densely granulate, 

 granules submuricate laterally. 



Head about twice as wide as long, feebly convex, more or less im- 

 pressed laterally and along the frontal suture, very densely and 

 scarcely coarsely punctate. Antenmr long, very feebly compressed 

 and scarcely at all dilated in outer three or four joints, third joint 

 scarcely as long as the next two combined, fourth to the eighth inclu- 

 sive subequal, the eighth subtriangular, ninth someAvhat triangulo- 

 orbicular, tenth orbicular, eleventh ovate. 



Pronotvm transversely oblong-oval, widest at the middle, about a 

 third wider than long; disc moderately convex, declivous about the 

 apical angles, very densely, rather coarsely, and more or less con- 

 fluently rugoso-punctate, granulate laterally; apex truncate in cir- 

 cular arc, marginal bead nearly obsolete ; sides evenly and moderately 

 strongly arcuate, feebly sinuate in basal eighth and not noticeably 

 constricted, marginal bead rather fine and almost entire; hasc trun- 

 cate in circular arc, obsoletely beaded, equal in width to the apex 

 and also to the length; apical angles obtuse and slightly rounded and 

 not in the least prominent; basal angles nearly obtuse and distinct. 



PropleinYc opaque and densely granulate. 



Eh/frn oval, a fifth to a third longer than wide, widest at the 

 middle; hase subtruncate, distinctly wider tlian the contiguous pro- 

 thoracic base; humeri obtusely rounded and not in the least promi- 

 nent ; sides evenly arcuate, a])ex rather broadly rounded and not in 

 the least produced ; disc moderately convex on the dorsum, strongly 

 rounded laterally, arcuately and more or less vertically declivous 

 posteriorly; surface densely and irregularly granulate, granules more 

 or less shining, sim])le and smaller along the suture, subuuiricate lat- 

 erally and on apex, where they are larger and moi'e discrete. 



Epiphnnut' moderately narrow, not dilated beneath the humeri and 

 gradually narrowing from base to apex, superior margins nearly 

 straight l)eneath humeri when \"i('\ve(l longitudinally and not visible 

 from above; surface smooth, finely and sparsely ])unctate.
