PHLOEOSINUS KANIKSU, new species 
Male—Black, with elytra reddish brown; 2.14 to 3.1 mm. long, 
holotype 2.71 mm. long, exactly 2.0 times as long as wide; allied to 
punctatus. 
Frons moderately wide between eyes, frontal rectangle about 0.80 
as long as wide; epistomal lobe very short; surface black, shining, 
densely, moderately granulate-punctate throughout, deeply, rather 
narrowly concave between eyes, its central area impunctate and 
brightly shining, with an elevated median carina on lower third; 
hairs short, fine, inconspicuous. Eye three times as long as wide, 
more than half divided by a moderately wide U-shaped emargination. 
Antenna with club slightly less than twice as long as wide, sutures 
all oblique. 
Pronotum about 1.13 times as wide as long, widest at posterior 
angles; sides on posterior half nearly straight and feebly converg- 
ing, then strongly, arcuately narrowed to the constriction just behind 
the broadly rounded front margin; surface black, moderately shin- 
ing, strongly, transversely impressed just back of anterior margin; 
disk with deep punctures of moderate size (slightly smaller and not 
so close as in either punctatus or rubicundulus), punctures gradually 
becoming smaller and closer anteriorly on disk, very dense and small 
near anterior margin, sides not granulate, with punctures denser than 
on disk; median line feebly elevated on posterior third; lateral calli 
very small or lacking; hairs short on posterior disk, slightly longer 
on anterior disk, considerably longer on sides (but not so long as in 
rubicundulus). 
Elytra slightly wider than pronotum, about 1.31 times as long as 
wide, widest at about middle; sides nearly straight and subparallel 
on anterior two-thirds, very broadly rounded behind; surface reddish 
brown, moderately shining; striae narrower and not so deeply im- 
pressed as in punctatus and rubicundulus, with somewhat smaller 
shallow punctures, striae wider and punctures slightly larger on sides; 
interspaces considerably wider than striae, feebly convex, densely, 
confusedly granulate-punctate anteriorly, with granules less numer- 
ous on posterior part and with little indication of a uniseriate ar- 
rangement on disk; hairs moderately short and stout, more numerous 
and much more conspicuous than in punctatus and rubicundulus, 
though still rather sparse. Declivity with striae not so strongly im- 
pressed as in its near allies, with the strial punctures less distinct; 
first and third interspaces elevated and serrate, with serrations dis- 
tinctly smaller than in either punctatus or rubicundulus, first inter- 
space with three serrations nearest apex greatly reduced or lacking, 
median portion finely, rather closely punctured ; second interspace nar-
