POROPTERUS COMMUNIS, n.Sp. 



Clothed with minute muddy- or sooty-black scales; prothorax 

 with elontrate blackish scales, at the sides and on each side of 

 carina with muddy-brown scales forming scarcely traceable lines; 

 apex and tubercles more or less feebly fasciculate; elytra with 

 2nd interstice feebly fasciculate, usually for but a short distance 

 but sometimes to sutural thickening (^ specimens occasionally 

 have muddy-brown scales forming numerous small macular towards 

 sides and apex); under surface more densely clothed than upper, 

 scales lai'ger and paler ; head and rostrum densely squamose. 

 Ciliation feeble, dull pale yellow, slightly visible with head in 

 position. 



Convex, subcylindric, tubercles small. Head without visible 

 punctures; smaller and more convex in (^; ocular fovea small; 

 eyes round, coarsely granulate; rostrum in ^ thick, curved, in 9 

 almost straight, thinner and almost parallel-sided, coarsely and 

 irregularly punctate, with a feeble carina extending from fovea 

 almost to apex; antennse rather thick; scape in ^ inserted about 

 two-fifths from apex, in 9 a little more, in ^ slightly passing, in 

 9 not reaching apex; 1st joint of funicle almost as wide as long, 

 2nd about once and one half the length of 1st, and not as long as 

 three following combined, 3rd-6th almost transverse, 7th as wide 

 as club (which is small), and almost adnate to it. Prothorax very 

 little longer than wide, flattened; apex produced, rounded, about 

 two-thirds the width of base; ocular lobes moderately prominent;
