POROPTERUS ASTHENIATUS, n.sp. 



Sparsely clothed above with muddy-brown and sooty-scales; 

 under surface — except abdomen — rather densely clothed, scales 

 rather large; legs densely clothed, scales brown, elongate, a few 

 projecting; head densely, rostrum moderately squamose. Ciliation 

 very minute, bright silvery. 



Convex, elongate elliptic, tubercles rather small. Head with 

 ocular fovea small, usually concealed; e^^es moderately granulate; 

 rostrum almost parallel, distinctly curved, the curvature most 

 distinct at base; antennae not very elongate, scape inserted at less 

 than one-third from apex, passing muzzle for more than half its 

 length (in 9 it is inserted farther from apex and does not extend 

 so far) ; funicle with short joints, 1st obconic, 2nd not much 

 longer and not as long as three following combined ; club large, 

 subadnate to funicle. Prothorax distinctly longer than wide; 

 apex produced, narrow, acutely bifurcate, not one-third the width 

 of base; constriction rather feeble; base truncate; anterior of the 

 lateral tubercles only feebly noticeable, the sides behind it sub- 

 parallel; median carina distinct at middle, continuous almost to 

 apex and base, a depression on each side of it, a feeble ridge on each 

 side reaching from bifurcation almost to median tubercles, these 

 latter moderately distinct, elongate; a few irregular granules at 

 base. Ehjtra distinctly punctate, including tubercles a little 

 more than twice the length of j^i^othorax, and wider before the 

 middle; 2nd interstice with an elongate tubercle at base slightly 

 projecting on to prothorax; summit of declivity (which is rather 

 elongate) with a feeble tubercle, between them a still feebler 

 tubercle (noticeable to the naked eye but obscured with a lens), 

 4th with three feeble tubercles; apical tubercles large, triangular? 

 conjoined at bases, diverging interiorly about 60°, subparallel 

 outwardly. Basal segment of abdomen fully twice as long as 2nd, 

 2nd feebly convex in the middle; intermediates feebly depressed, 

 distinctly shorter than apical, Femora in ^ reaching middle of 



apical segment, in ^ the base; tibioe feebly curved on their outer
