punctate, subapically maculate elytra, the larger and 

 smoother prothorax, and the longer antennae. The duller, 

 densely punctate, non-carinate, subapically maculate 

 elytra separate A. plicatus from A. basalis, Er., and A. 

 carinatus, Gorh. It is very probable that the present 

 species varies in the colour of the head and prothorax. 

 The apical joint of the maxillary palpi is rather stout, and 

 obHquely truncate at the tip.

Hab. Panama, Chiriqui. 



Extremely hke the Colombian A. basalis, Er. (a co-type, 

 (^, of which has been communicated by Prof. H. J. Kolbe 

 for comparison), but larger, the head and prothorax 

 broader, smoother, and entirely rufous; the elytra with a 

 similar very prominent submarginal carina, and a large 

 black patch at the base, the puncturing a httle coarser 

 and closer; the maxillary palpi stouter. From similarly 

 coloured A. rufipennis the present species may be known 

 by its more shining surface, carinate, more strongly 

 punctured elytra, and stouter palpi. The legs and antennae 

 vary in colour. Ten specimens seen. 



46. Attains viridimicans, n. sp. 



$. Elongate, rather convex, much widened posteriorly; brilliant 

 golden-green, the mouth-parts, palpi, anterior portion of the head, 

 antennae (the infuscate six outer joints excepted), trochanters, and 

 legs (the basal half of the posterior femora excepted), fiavo- 

 testaceous; sparsely, finely pubescent, without intermixed longer 

 hairs. Head very short, broad, faintly punctulate, the clypeus 

 very broad, longer than the labrum ; antennae slender, joints 3-10 

 longer than broad, 11 elongate. Prothorax short, convex, strongly 

 rounded at the sides, hollowed laterally at the base, faintly punctu- 

 late. Elytra of the same width as the prothorax at the base, at 

 the apex nearly one-half broader, somewhat rugulose, and finely, 

 distinctly punctate. Legs long, moderately slender, the posterior 

 tibiae feebly curved. 



Length 3^ mm.
