In the single specimen from Guatemala the median bristles of the interstices are 
more prominent than in North-American examples and the scales are shorter. There 
are no other differences of importance, and I do not regard it as distinct.

Hab. Mexico, Teapa!. 
I have received several specimens of this insect from M. Grouvelle out of imported 
bales of Mexican or Brazilian tobacco. It is rather smaller than C. icori@, and readily 
recognized by its vestiture of close ashy-grey scales, which are brown over an ill-defined 
patch on the prothoracie disc and a wide vitta covering the greater portion of the 
posterior half of the elytra, but not including the apex. ‘The interstices are set with 
rows of bristles. Chapuis describes the scales as luteous; I have had the advantage of 
seeing his type specimen, but cannot detect any such coloration in them. 
3. Chramesus tumidulus, sp. n. (Tab. VI. figg. 20; 20a, antenna.) 
Breviter ovatus, convexus, subopacus, fusco-piceus, elytris ferrugineo-brunneis, antennis subinfuscatis, squamis 
perbrevibus flavo-cinereis aspersus; prothorace semigloboso, conferte punctato, subtiliter reticulato ; 
elytris punctato-striatis, interstitiis fere planis, setis brevibus e granulis minutis egredientibus uniseriatim 
instructis. 
Long. 2 millim. 
Mas. Fronte impressa. 
Short-oval, robust, convex. Head black, subglabrous, the mouth rufescent; front (¢) broadly impressed, 
subnitid over the mouth, the side margins raised and tuberculate, the vertex dull, front ( 2) somewhat 
flattened, dull, finely punctured; antenne fusco-ferruginous. Prothorax hemispherical, widest at base, 
very slightly constricted in front, the sides and apex rounded, hind margin bisinuate and produced 
backwards in an obtuse angle; disc convex, fuscous-black, covered uniformly with minute scattered 
einereous scales, and with a few short hairs round the margins, rather dull, finely and closely reticulate, 
and rather closely punctured, the punctures submuricate towards the sides and apex. Scutellum minute, 
rugulose. Elytra as wide at the base as the prothorax, and more than one-half longer, their basal 
margins rounded, crenate, and elevated, the sides nearly straight to behind the middle, and thence 
rounded; above convex from base to apex, more strongly behind the middle, red-brown, rather strongly 
punctate-striate, the punctures rounded ; interstices very slightly convex, covered with very short and not
