2.5. A. periniiiiitiiin Smith.— Depressed, black; legs, antennae, beak and 

 tips of elytia yellowish or rufous; pubescence very sparse and inconspicuous. 

 Beak shorter than the head and prothorax, nearly straight, slender, cylindrical, 

 very finely strigose toward the base, impunctate, more or less shining. Antenuse 

 inserted close to the base, short, outer joints transverse, first but slightly longer 

 than the second and reaching the eye. Front rather narrow, with two more or 

 less distinct rows of punctures; eyes prominent. Prothorax wider than long; 

 both apical and basal constrictions strong, widest behind the middle ; punctures 

 rather coarse, sparse and unevenly distributed ; basal fovea large but not deep. 

 Elyti'a subparallel; humeri moderate; striae shallow; intervals rather wide, 

 slightly convex. Beneath sparsely, finely punctate ; claws nearly simple. Length 

 1.2-1.4 mm. ; .05-.06 inch. (PI. Ill, figs. 1 and la).

Widely distributed, but apparently rather scarce. An exceed-

 ever placed. The antennae are inserted nearer to the eyes than in 

 any species known to nie. There can hardly be a doubt that in the 

 fourteen examples befoi'e me both sexes are represented, but I am
