long, the emargination being unusually deep; the basal node of the 

 fourth joint is distinct and a little longer than wide. 



The single species is described below; it has comparatively little 

 affinity with Ampeloglypter, where it was provisionally placed by 

 LeConte. 



1 Desmoglyptus crenatus Lee. — Proe. Am. Phil. Soc, XV, p. 300 

 (Ampeloglypter) . 



Very narrow, subcylindrical, pale red-brown throughout and 

 densely opaque, the setae not distinct. Head rather convex, 

 minutely, obsoletcly punctate, the beak equal in length to the 

 prothorax in the male, robust, strongly, evenly arcuate, feebly flat- 

 tened toward apex, obsoletely punctate, the antennae inserted well 

 beyond the middle, normal in structure, the first funicular joint as 

 long as the next three, two to seven equal in length, the outer 

 gradually slightly wider, the club oval, about as long as the pre- 

 ceding five joints together, pubescent, with the basal joint constitut- 

 ing much less than one-half the mass. Prothorax nearly as long 

 as wide, the apex broadly subtubulate, the sides parallel and straight 

 in basal two-thirds ; apical margin feebly arcuate and three-fourths 

 as wide as the base ; disk without impunctate line, the punctures 

 rather coarse, deep and dense. Scutellum small, rounded. Elytra 

 three-fourths longer than wide, a little wider than the prothorax 

 and about twice as long as the latter, the humeri slightly promi- 

 nent ; sides parallel in basal three-fifths, broadly sinuate behind the 

 humeri, the apex narrowly subtruncate ; disk of each strongly urn- 

 bonate or callous in the middle near apical fourth, the striae coarse 

 deep and impressed, remotely but strongly crenate, the intervals 

 narrow, convex, each with a single series of remote minute and 

 excessively feeble punctures, which are scarcely at all observable 

 under moderate power. Abdomen not densely punctate, with a 

 very large broad and deep basal impression in the male ; in this 

 sex the thickened posterior edge of the fifth segment is deeply, 

 transversely excavated opposite the apex of the pygidium, and 

 from the bottom of this excavation there projects a small, short and 

 transverse polished tubercle. Length 2.7-3.0 mm.; width 1.0 mm. 



The two specimens before me are males and one of them is 

 labeled "Arizona." LeConte gives Virginia and Maryland as the 

 habitat of his types.
