CORYMBITES Latr. 



C. teres, cylindricus, nigro piceus, fusco pubescens, fronte depressa, 

 capite thoraceque dense fortiter punctatis, punctis umbilicatis, lioc latitadine 

 longiore, convexo, lateribus rectis parallelis, angulis posticis vix obsolete cari- 

 natis, baud divergentibus ; elytris striis subtiliter punctatis, interstitiis planis 

 punctnlatis ; antennis pedibusque fuscis, illis articulo 3io 4to aequali, tnangu- 

 lari. Long. 12-5 mm. 



One female froti California, given me by Mr. Ulke. Tbis species is allied to 

 C. cylindriformis, but differs by tbe coarse and dense punctures of tbe 

 bead and tborax ; tbe latter is not channeled. The antennae scarcely attain tbe 

 base of the elytra, which are slightly tinged with brassy lustre. 



C. trapezium, niger, nitidus, vix conspicue pubescens, thorace latitu- 

 dine breviore, fortiter marginato, lateribus rectis antice convergentibus, 

 angulis posticis divarhatis, baud carinatia, disco paulo convexo, confertim 

 punctato ; elytris subtiliter punctatis, punctisque paulo majoribus striaetini 

 positis, margine latiusculo reflexo ; antennis articulis 3 11 conipressis, 

 sensim paulo angustioribus, 3io 4to aequali. Long. 21-5 mm. 



Texas ; sent to me by Mr. A. Salle. Tbis remarkable species does not 

 resemble any other seen by me, but I have found no characters to warrant me 

 in separating it as a distinct genus. The body is elongate, not convex, shining 

 black above, and almost glabrous. The head is punctured and the front is 

 broadly concave, or rather excavated ; the antennae are longer than the head 

 and thorax : the second joint small, the third equal to the fourth, triangular 

 compressed, following joints gradually a little narrower, eleventh distinctly 

 divided, terminal portion a little shorter. Thorax trapezoidal, sides straight, 

 strongly margined; hind angles divergent, not carinated; di^c only slightly 

 convex, tolerably thickly punctured. Elytra as wide as the thorax at the 

 hind angles, lateral margin strongly refiexed, disc finely punctured, with not 

 very obvious striae composed of somewhat larger punctures. Hind coxae vevy 

 narrow externally, gradually somewhat widely dilated inwards (about as in 

 C. aethiops). Front tibiae compressed, longitudinally concave on the 

 anterior face ; tarsi compressed, more densely pubescent beneath than usual, 

 not shorter than the tibiae. Front lobe of presternum very short. 



C. op a cuius, niger, subopacus, dense helvo-pubescens, capite punctato, 

 fronte concava, thorace latitudine baud longiore, convexo, obsolete canalicu- 

 lato, dense punctato, lateribus late rotundatis, angulis posticis acutis diver- 

 gentibus, carinatis ; elytris striis profunde punctatis, interstitiis angustis 

 rugose punctatis ; tibiis tarsisque obscure ferrugineis, antennis articulo 2ndo 

 parvo, 3io triangulari sequente vix angustiore. Long. 8 - 5 mm. 



Oregon; in Mr. Ulke's collection. Somewhat allied to C. divaricatus 

 Lee, but the sides of the thoiax are rounded. The antennae are broadly ser- 

 rate, and a little longer than the head and thorax in the specimen described. 



C. nicer ens, elongatus, niger, opacus, subtilissime cinereo-pubescens, 

 capite confertim punctato, fronte convexa, vage triangulariter impressa, tho- 

 race latitudine fere duplo longiore, parum convexo, dense punctato, lateribus 

 late sinuatis, angulis posticis divergentibus, apice truncatis, baud carinatis ; 

 elytris striis punctulatis, interstitiis fere planis, punctatis ; antennarum arti- 

 culo 2ndo parvo, 3io triangulari sequente paulo longiore. Long. 11 mm. 



Oregon ; in Mr. Ulke's collection. The antennae in the specimen before me 

 are as long as the head and thorax ; the third joint is as broad as the fourth, 

 and slightly longer. 



This species is allied to C. lobatus, but is larger, of a more opaque black 

 color, and tbe tborax is longer and less convex.
