Lato-ovatus, parum convesus, obscure rufo-brunneis ; elytris opacis,

L. 3 mill. 



Broadly oval, pitchj brown or dark reddish brown, shining, 

 elytra opaque ; the head smooth and shining, frontal stride 

 complete, 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 sulcus 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, striae 1-4 and sutural are complete, sutural and 4 

 joining at base, the striae are rather wide, with minutely crenu- 

 late edges, 5 is shortened before the base, the interstices are 

 flat and opaque ; epi pleurae bistriate ; the propygidium is 

 clearly and not densely punctulate, the punctuation of the 

 pygidium is less distinct ; the presternum, lobe with scattered 

 and fine points, keel narrow, striae 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 striae are also similar to those of 

 C. AlarsJ/alli, 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 carina3 of the elytra is a character seen iu no other 

 known Histerid.
