148 OCELOCEPHALUS. 



4. Ccelocephalus fusco-costatus. 



C. oblongo-ovatus, robustus, pallide testaceus ; capite brevi, reflexo, 

 inter oculos transverse dej>resso, punctata, inter oculos fusco 

 suffluso ; thorace quadrato (subelongato), ad basin constricto et 

 transverse depresso, punctidato ; elytris sat robustis, paraUtlis, 

 punctato-striatis, ad basin medium circidariter rnaculatis, etiam- 

 que transverse ad medium suturam ; lateribus fusco suffusis ; 

 antennis hngis, Jiliformibus, art. 1-3 fuscis, 4 et 5 testaceis, (5 

 fusco, 7 et 8 nigro-fuscis, 9-11 testaceis ; pedibus pallide testaceis. 



Long. corp. 2 lin., lat. f lin. 



Oblong-ovate, rather more parallel than G.pygmceus, robust, pnnc- 

 tate-striate, subpubescent, pale testaceous. Head short, depressed, 

 reflected backwards at a sharp and acute angle ; eyes large, very pro- 

 minent, projecting laterally beyond the margin of the thorax, situ- 

 ated immediately at the back of the head ; the base of the antenna) 

 is prominent, and situated directly on the angle of reflection ; im- 

 mediately above it, and between the eyes, is an obsolete T-shaped 

 depression ; the surface is finely punctate, more distinctly at the 

 base, between the eyes suffused with dark fuscous. Thorax quadrate 

 (slightly elongated), distinctly constricted at the base ; the anterior 

 angles depressed ; the sides marginate ; at the base is a broad trans- 

 verse depression, which extends as far as the margination ; the sur- 

 face is finely punctate, subpubescent. Scutellum triangular, fuscous. 

 Eh/tra broad, robust, parallel, broadly punctate-striate (the punctures 

 being broad and shallow), subpubescent : at the base is a large semi- 

 circular spot common to each elytron and surrounding the scutellum 

 (this marking is equal in breadth to the base of the thorax) ; at the 

 bine of margination is a longitudinal suffused fuscous marking, ex- 

 tending from the shoulders nearly to the apex, while on the suture 

 (between the middle and the base) is a small suffused fulvous 

 marking, obliquely transverse. Antennae twice the length of the 

 elytra, filiform ; the first and second joints dilated ; the first, second, 

 and base of the third fuscous ; the fourth and fifth testaceous ; the 

 sixth fuscous ; the seventh and base of the eighth dark fuscous, in- 

 clined to black ; the rest pale testaceous. Legs pale testaceous 

 throughout; the globular inflation over the posterior claw bright 

 ferrugineous. 



This species may be distinguished from C. pygmmis (to which it 

 is very closely allied) by the different form of the thorax, the co- 

 louring of its antenna?, and the fuscous margination on its elytra. 



From the district of the River Amazon.
