third joint distinctly longer than the fourth but much shorter than the fifth. 

 Protliorax slightly wider than the head and a little wider than long, the apex 

 very slightly narrower than the base, both feebly arcuate ; sides strongly, 

 obtusely tuberculate at the middle ; disk finely, densely punctate, scarcely at 

 all impressed along the middle where the punctures are sometimes but not 

 always sparser. Elytra at base not more than one-third wider than, the 

 prothorax, about two and one-third times longer than wide ; sides distinctly 

 convergent from base to the apex, which, conjointly, is broadly and evenly 

 rounded ; disk very coarsely and sparsely punctate toward base, the punc- 

 tures becoming gradually fine toward apex and along the suture. Length 

 9.3-11.0 mm. ; width 3.2-4.0 mm.

The five specimens before me are without definite indication of 

 locality, but as they are from the Levette cabinet they were in all 

 probability taken in or near the region above stated. These speci- 

 mens are apparently all males, and the species appears to be related 

 to tenebrosa, which is described from a unique female. I do not 

 think however that subvittata can be the male of tenebrosa, for in 

 that case the general direction of the sexual differences, as shown 

 in miriftca by Dr. Horn, would be rather reversed, the elytra in 

 the male of miriftca being almost impunctate, while in the female 

 they are very coarsely so.

The series in my cabinet seem to show that A. subpilosa is a 

 species entirely distinct from lupina. The former is extremely 

 sparsely punctate, the pubescence ver} T easily removable, but denser 

 and persistent is a very narrow line bordering the elytral suture, 

 giving it a narrowly vittate appearance, while in lupina there is no 

 indication of this sutural condensation, and the discal punctures are 

 between two and three times as dense, the pubescence being much 

 more persistent. 



The species longicornis and ligata are perfectly identical, and 

 the latter should be regarded as a synonym of the former, not a 

 variety. Gibbtda is a synonym of proteus and not a variety, as it 

 is printed in our lists. 



A. variipes n. sp. — Rather slender, strongly convex, shining, deep 

 black ; antennae dark brown, with the basal joint darker and blackish ; ante- 

 rior legs throughout and the intermediate and posterior femora feebly and 

 suffusedly near the coxae only, pale rufo- testaceous ; pubescence very short 

 and sparse, longer on the anterior portions. Head about equal in width to
