EPHALUS LeConte. 



A cosmopolitan genus with tew species, of which one occurs in the 

 United States. A single fossil lias been found in Colorado, probably belong- 

 ing here. 



EPHALUS ? ADUMBRATUS. 

 EphahiK? <xliiiiil>rii1iix Scudd., Tcrt. rhynrh. Col. V . S.. pi. L, tig. 3 (1892). 



Head la rye, apparently almost as broad as the prothorax, but all the 

 specimens give a side view only, the surface uniformly granulose; eyes 

 moderately large, nearlv circular, but a little transverse; antennae rather 

 coarse, especially the apical half, where the joints are nearly twice as long 

 as broad, the whole hardly reaching back to the elytra. Thorax granulose, 

 exactly like the head, both anterior and posterior margins straight and trun- 

 cate in most of their course, a distinct lateral plica or carina, the whole 

 much broader than long. Elytra with well-rounded humeral angle and 

 feebly punctured stria'. Legs, especially tibia', slender, the spurs small, 

 the anterior pair broader, with prolonged outer angle. 



Length, 4.(j mm.: breadth. '2 mm. 



1 have placed this species in Ephalus with some doubt, but it seems to 

 belong in the ( )patrini, and I iiud nothing nearer in point of structure. 



Florissant, Colorado; three specimens, Nos. 6506, 764(5, 14247. 



IIELOi'S Fabrieius.
