LECONTE ON EOCKY MOUNTAIN COLEOPTEEA. 459 



rouuded, rather finely margined, obliquely truncate, but not sinuate 

 behind; angles rounded, base bisinuate, finely margined; surface 

 sparsely but strongly punctured, almost without punctures in front. 

 Elytra with dentiform humeral angles, striae fine, strongly punctured, 

 interspaces flat and smooth. Mesosternum densely punctured, not cari- 

 nate. Spinules of hind tibiae unequal. Length 6.4™™ (0.25 inch). 



Moriposa, Cal. ; one specimen, given me by the late Mr. J. Thevenet, 

 of Paris. This species is much less robust than A. ovipennis; the elytra 

 are not narrowed near the base, and the punctures of the prothorax are 

 less numerous. 



28. Aphodius nuMEEALis, n. sp. 



More robust and convex, shining black. Head finely alutaceous, not 

 punctulate; epis to ma feebly but broadly emarginate in front, angles very 

 much rounded, not obvious, sides oblique; gense prominent, subacute. 

 Prothorax very convex, sides feebly rounded and finely margined ; hind 

 angles obliquely and broadly emarginate (when looked at from above); 

 marginal line of base punctured ; surface with a few scattered large punc- 

 tures, smooth in front. Elytra very convex, slightly narrowed near the 

 base, humeri prominent, tuberculiform ; striae deep, marked with large 

 distant punctures : interspaces somewhat convex, smooth. Mesosternum 

 coarsely punctured, not carinate. Spinules of hind tibiae (much worn, 

 but apparently) unequal. Length 3.6^™ (0.14 inch). 



Detroit, Mich.; one specimen, sent me by Messrs. Hubbard and 

 Schwarz. This species is remarkable both for locality and characters, 

 all of its allies, whether of this group or of group G, being found in the 

 Central and Pacific districts. 



BUPRESTID^. 



29. Anthaxia deleta, n. sp. 



Of the same form, color, and size as A. viridifrons^ brown-bronze tinged 

 with olive. Head ( 3 bright green), finely reticulate, flat, perpendicularly 

 declivous. Prothorax truncate before and behind, broadly rounded on 

 the sides ; very obsoletely, scarcely perceptibly reticulate, finely rugose, 

 opake. Elytra distinctly granulate- punctate at the base, then finely but 

 obviously punctured. Beneath black-bronzed, shining, antennae and 

 legs green. Length 4.6™™ (0.18 inch). 



American Fork Caiion, Utah, (9,500 feet) ; only dififers from A. viridi- 

 frons by the head and prothorax being more finely sculptured, while the 

 elytra are more deeply sculptured. 



30. Cheysobothris caeinipennis, n. sp. 



Dark gray, slightly bronzed. Head somewhat hairy, coarsely con- 

 fluently punctured, with two small smooth calli. Prothorax very trans- 

 verse, rounded on the sides, very coarsely punctured, with irregular, 

 smooth, elevated cicatrices; an irregular rhomboidal dorsal space, limited
