Coproxenus opacipennis, sp. i. 
Lato-ovatus, parum convexus, obscure rufo-brunneis ; elytris opacis, 
utrinque bicarinatis, interstitiis planis, striis 1-4 et suturali in- 
tegris, 5 basi abbreviata ; prosterno angustato, bistriato. 
L. 3 mill. 
Broadly oval, pitchy brown or dark reddish brown, shining, 
elytra opaque; the head smooth and shining, frontal strize 
complete, n narrowly straight in front, with the space behind 
deeply impressed ; the thorax clearly, not closely punctured, 
lateral stria continued behind the neck, anterior angle some- 
what acute; the elytra are somewhat parallel between the 
shoulders until before the apex, the edge is a thick raised 
keel rounded off before and behind, within this keel there is a 
sulcus, and in the suleus eight smooth little red bosses, 
within the bosses is a second carina (corresponding to a com- 
plete subhumeral internal stria) which is broken in four or 
five places, strie 1-4 and sutural are complete, sutural and 4 
joining at base, the striz are rather wide, with minutely crenu- 
late edges, 5 is shortened before the base, the interstices are 
flat and opaque; epipleure bistriate ; the propygidium is 
clearly and not densely punctulate, the punctuation of the 
pygidium is less distinct; the prosternum, lobe with scattered 
and fine points, keel narrow, strie meet in front and widen 
out slightly at the base, each stria has a regular row of about 
a dozen punctures along its course, interstice narrow ; the 
mesosternum, stria strong and complete, but without the 
second stria on the margin, transverse stria as in the last 
species ; the metasternal striz are also similar to those of 
C. Marshall, but they are regularly and conspicuously punc- 
tate, the surface is opaque, with a microscopic sculpture, and 
there is a series of irregular punctures on either side of the 
median line. 
The remarkable row of little red bosses between the two 
lateral carine of the elytra is a character seen in no other 
known Histerid.
