of the head set with bristly hairs. Head short, broad, about as 

 wide as the prothorax, transversely depressed in front, the eyes 

 rather large; antennae comparatively short, feebly serrate, joints 

 3-11 longer than broad. Prothorax transverse, rather convex, 

 rounded at the sides, very little narrower at the apex than at the 

 base. Elytra long, subparallel, slightly wider than the prothorax 

 at the base. Legs elongate, slender. 

 Length 3 J mm. 



Hab. Mexico {ex coll. Somnier, in Mus. Oxon.). 



One female. More elongate than A. plumbeus, greenish- 

 oHvaceous in colour, the head about. as wide as the pro- 

 thorax and transversely excavate in front, the antennae 

 shorter, the prothorax more convex, the elytra longer and 

 subparallel. A. olivaceus is very hke a Dasytes, and it 

 might be mistaken for a species of that genus. The male, 

 unfortunately, of both A. plumbeiis and A. olivaceus, is 

 unknown; but the insects unquestionably belong to the 

 Malachiides, and they are probably correctly placed in 

 Attains. 



44. Attains plicatus, n. sp. 



Moderately elongate, widened posteriorly, shining; rufo-tes- 

 taceous, the elytra with a common basal fascia (excised along 

 the suture behind) and a transverse subapical patch on the disc, 

 a broad space across the metasternum beneath, the legs, the apical 

 joint of the maxillary palpi, and joints 5-11 of the antennae, black, 

 joints 1-4 of the latter obscure testaceous ; finely pubescent, without 

 intermixed longer hairs. Head broad, transverse, minutely punc- 

 tate, obsoletely bifoveate in front ; antennae long, stout, moderately 

 serrate, joints 3-11 longer than broad. Prothorax amjile, trans- 

 verse, convex, very shining, sparsely, excessively minutely punctate. 

 Elytra moderately long, at the base scarcely wider than the pro- 

 thorax, much widened posteriorly, somewhat opalescent, trans- 

 versely depressed below the base and distinctly plicate laterally 

 from the humeral callus to about the middle ; densely, conspicuously 

 punctate. 



(J. Anterior tarsi with the prolonged pallid upper portion of 

 joint 2 reaching the apex of 3. 



Length 3 mm. (cJ.)

One male. Near A. nifiiiennis, differing from all the 

 forms of that species in the laterally plicate, more coarsely
