San Diego, California, under decomposing Opuntia stems. Of a dull black color, 

 above finely granulate, without lustre except on the abdomen. Head sparsely 

 punctured, thinly clothed with short suberect hair, obtusely pointed anteriorly, eyes 

 oblong, not prominent ; antennae as long as the head and thorax, third joint a little 

 longer than the second, fourth only half the length of the third, 5 — 10 transverse, 

 gradually a little broader, sparsely pilose with verticillate hairs, 11th longer and 

 narrower than the preceding, conical, obtusely rounded at tip. Thorax a little 

 broader than long, transversely slightly convex, anteriorly broadly emarginate, sides 

 and base curved with a circular outline, anterior angles rounded, slightly deflexed, 

 finely not densely punctured, covered with short erect black hair. Elytra shorter than 

 the thorax, punctured and hairy like it, flattened, truncate with the outer angle 

 rectangular and rounded. Abdomen above shining, sparsely pubescent and punctured, 

 parallel on the sides, obtusely rounded at the tip ; anterior segments transversely 

 impressed and smooth towards the base ; sides strongly reflexed, pilose with longer 

 black hairs : anus sanguineous. Body beneath densely punctured and pubescent with 

 blackish brown hair. 



Varies much in size, but usually larger than any other species of the genus and 

 having a peculiar habit. I was at first inclined to regard it as a new genus, but after 

 a patient examination and dissection I failed to find any character by which it might 

 be separated. 



Canthon v i g i 1 a n s , rotundato-ovalis, parum convexus, ater opacus vix senescens, clypeo subtilius granulates 

 antice bidentato, sinubus ocularibus latiusculis ; tborace lateribus angulatis, margine ante medium, 

 inferne interrupto, et tuberculo minute praedito ; elytris obsolete striatis ; fossulis pedum anticorum 

 distinctis. Long. -67 — - 85. 



Texas, Georgia, Missouri : Precisely like C. 1 se v i s , and chalcitesin general 

 appearance. The granulation of the surface is finer than in the first, but much coarser 

 than in the second ; and it differs from both species by the greater breadth of the por- 

 tion of the eye which is seen in the clypeus. 



Cremastochilus s a u c i u s , rufo-castaneus, nitidus, thorace transverso, angulis anticis auriculatis, posticis 

 incisis et retrorsum acuminato-productis, disco ad angulos anticos breviter, intra posticos longe exarato, 

 parte mediana sequaliter subtilius punctata, lateralibus incrassatis, convexis laevibus, extrorsum punctatis ; 

 elytris punctis elongatis sat densis insculptis ; pygidio punctato, subcarinato : mento parum concavo, 

 margine postico subangulato, baud inciso. Long. -42. 



Lodge Pole Creek, (Nebraska,) Mr. W.Wood ; Llano Estacado, Capt. Pope. Readily 

 known by the remarkable form of the thorax, the surface of which is divided into 

 three lobes by the meeting of the long posterior, and the short anterior excavations,
