POROPTERUS LUTULENTUS, n.Sp. 



Very densely clothed all over with microscopic muddy-brown 

 scales, prothorax with elongate sooty scales just showing; elytral 

 fascicles just traceable; under surface and legs sprinkled with 

 larger paler scales which are scarcely longer than wide; head, 

 rostrum and claw- joint densely, scape and pectoral canal slightly 

 squamose. Ciliation minute, pale silveiy-yellow. 



Convex, tubercles very small. Hi^Md feebly convex ; eyes 

 rounded, coarsely granulate; ocular fovea invisible; rostrum rather 

 short, almost straight and parallel; scape inserted about two-fifths 

 from apex, passing muzzle, apex a little more suddenly thickened 

 than is usual in the group; 1st joint of funicle obconie, almost as 

 wide as long, 2nd about once and one-half the length of 1st, and 

 not as long as three following combined, 3i'd-6th scarcely, the 7th 

 distinctly transverse; club short, almost free. Prothorax feebly 

 convex, distinctly longer than wide; apex produced, almost trun- 

 cate, more than half the width of base; constriction feeble; sides 

 feebly rounded in the middle, decreasing a little less to base than 

 to apex ; transverse tubercles scarcely traceable, the lateral (if 

 anything) a little more distinct, median carina just visible, sides 

 at apex with a feeble ridge; with large punctures entirely con- 

 cealed by scales. Elytra a little more than twice the length of 

 prothorax and with the base a little wider, very feebly widening 

 to apical third; declivity abrupt; sutuxe feebly thickened; apex 

 rounded, 2nd interstice and shoulders feebly but distinctly pro- 

 duced; with regular rows of fovese nearly touching, but almost 

 entirely concealed by scales. Basal segment of ahtJomen not once 

 and one-half the length of i*id, intercoxal process broad, its sides 

 very feebly raised ; 2nd flat, sloping towards intermediates, its 

 sutures almost entirely concealed ; intermediates very feebly 

 depressed below apical and not as long; apical with trace of a 

 feeble transverse impression. Posterior jemura long and rather 

 thin, reaching middle of apical segment; tibife compressed, anterior 

 very feebly curved and a little shorter than posterior; tarsi sub-
