16 FREDERICK BLANCHARD. 



15. C. floridie Gaud.— Elongate, rather obtuse before and narrowed heliind, 

 rufotestaceous or fuscous above and below, clothed with brownish cinereous pu- 

 bescence and short and fine bristles, the surface beneath shining. Antennae, 

 slender, feebly serrate, joints narrow, elongate, as in the preceding three .species, 

 length about equal to the head and thorax, basal two joints yellow, outer ones 

 darker. Head, with a few coarser punctures and thorax thickly punctulate, 

 punctures not evident on the latter; the thorax is convex, scarcely or not longer 

 than wide, more strongly narrowed in front, the sides strongly rounded, nar- 

 rowed and feebly sinuate behind, the angles hardly or not diverging, faintly 

 channeled posteriorly at middle, the basal plicte short. Elytra widest behind the 

 humeri thence rounded and narrowed to tip, strongly .striate, with rather closely 

 placed subquadrate punctures, intervals convex, punctulate. Body beneath 

 punctulate, sparser, coarser punctures evident on the metasternum, hind coxae 

 and middle of abdomen; prothorax with the submarginal lines distinct, im- 

 pressed, reaching nearly to the anterior third, prosternal process long, hori- 

 zontal as in the previous species, marginal lines extending to tip and contiueiit 

 anteriorly with the well marked antecoxal lines; mesosternum as in the ()re- 

 vious species, hind coxae with posterior margin transverse, the angle strongly 

 rounded. Legs slender, yellow as in the jn-eceding. Length ..33-. .35 inch ; 

 8-9 mm. 



Florida. Several specimens. 



Although the thorax is actually no wider than the elytra the en- 

 tire insect often has an appearance of being narrowed from the ante- 

 rior part of the thorax to the tip of the elytra. Very similar to 

 convexus, but the shorter thorax and rather more strongly striate 

 elytra as well as the usually paler color seem to distinguish it. The 

 sparser, coarser punctures very evident on the prothorax in some 

 specimens of convexus do not here appear The head and thorax are 

 usually a little darker than the elytra and beneath the pro- and 

 metathorax are darker than the abdomen. If it were not for the 

 existence of a typical specimen in the LeConte cabinet sent by 

 Candeze I should be inclined to refer this species to insulsus Cand. 

 and to consider the name fioridae as a synonym of convexus Say. 



16. C longior Lee. — Elongate, shining, black, clothed with fine, incon- 

 spicuous, fuscous pubescence and short curved bristles ; thorax longer than wide : 

 legs varying from black to yellow. Antennae slender, as long as the head and 

 thorax, but feebly serrate, joints narrow. Head with the front strongly mar- 

 gined and distinctly produced at middle, impressed behind the margin, faintly 

 hi impressed on the vertex, rather closely punctulate, coarser punctures not evi- 

 dent. Thorax moderately convex in the % or more strongly in the 9- longer 

 than wide, narrowed before and obliquely a little less behind, and broadly, feebly 

 rounded on the sides in the'^ .orstrongly rounded and widest in front of the middle 

 in the 9 • finely, closely punctulate with the coai'ser punctures scarcely evident to 

 more strongly with the punctures distinct, hind angles not divergent, carinate, 

 basal fissures long, a median posterior linear impre.ssion, base tridentate at middle, 

 median tooth broader and less prominent. Elytra with sides rounded and nar-
