Ml'. A. Murray on Coleoptera from Old Calabar. 319 



A number of specimens have been received. They vary a good 

 deal in intensity of colour and degree of denudation of pubes- 

 cence. 



Erymanthus, Klug. 



Erymanthus horridus, Westw. Proc. Zool. Soc. 1832, p. 35. 



Erymanthus vesuvioides, Thomson, in Rev. et Mag. Zool. 1856, p. 114. 



Var. purpureo-niger. 



Three specimens. 



Prof. Westwood describes and figures his species as shining 

 black, with rufo-piceous protuberances. M. Thomson's speci- 

 mens of E. vesuvioides are described and figured as varying in 

 colour, the ground-colour being ferrugineo-testaceous encroached 

 upon by brown and black. My specimens are all three of a i-ich 

 shining dark tawny claret-colour, almost black, with rufo-piceous 

 or tawny brown shining through on the tops of the tubercles. 

 With the exception of the differences in colour, I see no distinc- 

 tion between ray specimens and the descriptions and figures of 

 these species respectively given by Westwood and Thomson. 

 They all come from West Africa: — Prof. Westwood's from Cape 

 Palmas; M. Thomson's from Grand Bassam; and mine from 

 Creek Town, Old Calabar. 



Thanasimodes, nov. gen. (See fig. 2, p. 320.) 



Elongatus; palparum maxillarium ultimo articulo securiformi. 

 Prothorace subquadrato, angulis rotundatis ; elytris longis ; 

 femoribus posterioribus hand apicem elytrorum attingentibus; 

 ceteris fere ut in Thanasimo. 



Elongate, subcylindrical, shining and metallic. Mentum 

 transverse, narrow. Ligula bilobed, the lobes diverging. Last 

 article of the labial palpi very large, transversely securiform ; 

 that of the maxillary palpi also securiform, but not half so broad. 

 Labrum emarginate. Head declined, ovular. Eyes rather large, 

 nearly on a level with the rest of the surface of the head in 

 front, but projecting a good deal behind, the head being nar- 

 rower behind them ; rather strongly emarginate on the under- 

 side, distinctly but not coarsely granulated. Antennse longer than 

 the head and thorax, rather slender, of eleven articles, the first 

 conical and bent, second to eighth flattened subcylindrical, second 

 moderately long, third longer than the second, fourth about the 

 length of the second, fourth to eighth gradually but very slightly 

 increasing respectively in length and thickness ; the ninth to 

 eleventh triangular and a little thicker than the preceding, 

 forming a loo^se slender club; the eleventh largest, unequally 

 ovate, and acuminate. Prothorax subquadrate, convex, with 

 the sides subparallel and the angles rounded, constricted at the
