170 THE CANADIAN ENTOMOLOGIST. 



Elaphidion, Serv. 



E. Fuchsii, n. sp. — Rufo-castaneous, shining, clothed with rather long, 

 whitish, recumbent pubescence that does not conceal the surface. Form 

 moderately elongate. Head with rather deep, longitudinal frontal impres- 

 sion, front coarsely and moderately densely punctate, the punctures 

 becoming closely cribrate in the occipital region which, with the vertex, 

 is indistinctly carinate. Antennas (male) scarcely attaining the tip of the 

 elytra, pubescent and sparsely hairy, very feebly serrate, third joint with 

 a short internal spine which is less than one fifth the length of the fourth 

 joint, fourth and fifth joints still more feebly unispinose. The third and 

 fifth joints are about equal in length and are a trifle longer than the 

 fourth; the outer edges of the third and following are compressed and 

 rather sharp, eleventh constricted and suddenly smaller near the tip. 

 Prothorax ellipsoidal, convex both ways, sides regularly arcuate, base 

 broader, than the apex, hind angles distinct ; disk coarsely and closely 

 punctate, a poorly defined median line, best marked just behind the 

 middle where it is smooth and elevated. On each side are two elevations 

 which correspond to the callosities usually found in this genus, but they 

 are not different in sculpture from the rest of the surface. Scutellum 

 rounded, finely emarginate behind and clothed with fine, dense whitish 

 pubescence. Elytra broadest across the humeri, humeral umbone limited 

 internally by a distinct impression ; sides slightly convergent towards the 

 tip, no well-defined costse, though faint traces may be seen. Punctuation 

 deep, rather coarse, well-separated, much finer towards the tip ; apices not 

 quite regularly separately rounded, with a moderately long, sharp sutural 

 spine, outside of which is a short tooth. Body beneath finely scabro- 

 punctate, punctuation closer than above. Legs paler, tibi?e carinate, 

 thighs not toothed nor spined. Length, 21 mm , =.84 inch. 



This is one of the forms connecting Elaphidion with Aneflus, and I 

 quite agree with Major Casey that the latter genus is untenable under the 

 present definition. The type is a male from Independence, California, 

 where it was captured by myself, about the middle of July, by beating 

 desert shrubs. The female is slightly larger, less slender, the antennie 

 only about two-thirds the length of the body and the apex of the elytra is 

 scarcely spinose, the spines being much reduced. 



The relationshi[)s of this species are sufficiently well indicated by the 

 characters given in description. It is evidently very distinct from all of 

 our other species in the combination of antennal and elytral characters.
