by its greeniBh-acneous colour, and the dense, cinereous 

 pubeacence intermixed with very long, erect bristly hairs, 

 these latter extending to the legs also ; th(^ head (incorrectly 

 described as subrostrate) is much piolonged behind the 

 eyes; the elytra are so densely ])unctate as to appear dull 

 and scabrous, the numerous setigerous impressions giving 

 a speckled appearance to the surface. Anthocomus sericans, 

 Er. (1840), is an Attains, and the specific name used by 

 Corham is therefore preoccupied. 



5. Attains nigritulus.

Moderately elongate, narrow (tJ), broader and more widened 

 posteriorly in ^|^, shining; black, the elytra usually with a faint 

 brassy or greonisii lustre, tlic basal joints of the antennae externally, 

 and the two basal joints of tlie anterior tarsi in <^, testaceous, the 

 logs piceous ; sparsely pubescent, the elytra with intermixed, erect, 

 longer hairs, similar to those on the exposed portion of the abdomen. 

 Head relloxed in repose, considerably jiroduced behind the eyes, 

 broader in (J' than in 9, polished, very sparsely, obsoletely punctate, 

 tlie inter-ocular portion Jlatlened or depressed; eyes large. Pro- 

 tliorax narrower than the elytra, not much broader than long, 

 convex, polished, almost smooth. Elytra moderately long, much 

 wider than the prothorax, rugulose, closely, finely punctate. 

 Legs long and slender; posterior tibiae bowed in both sexes. 



(J. Antennae elcmgate, distinctly serrate ; anterior tarsi with 

 the prolonged u])])cr portion of joint 2 reaching the apex of 3.

 longer than broad, 11 more elongate.

Not unconnnon in Mexico. (Jorham's description was 

 made from dirty female examples. The male is very like a 

 Dasyles. In one specinuMi of this sex the apices of the elytra 

 are compressed and subacuminate, but this is partly due 

 to shrinkage after death. The elytra vary a little in length, 

 and the head in one of the females named by Gorham is 

 much elongated, as seen detached from the prothorax. 

 The longer head separates A. nigritulus from various allied 

 forms.
