336 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
forehead punctate-rugose, bifoveolate in front. Thorax very thickly and finely rugulose, 
opaque. Scutellum very thickly punctate, opaque, truncate at the apex. Elytra very 
thickly and faintly rugulose, opaque, concolorous, with almost imperceptible, small, , 
shallow surface-impressions in rows, the impressions smaller, closer together, and more 
oblong than in C. femoralis. Abdomen thickly punctate, somewhat shining. Legs 
pitchy black. 
Very closely allied to C. niger, C. femoralis, C. rufipes, and C. Mexicanus. The fol- 
lowing are some of the distinguishing points :—C. niger has the thorax much more 
coarsely punctate than any of the rest. ©. femoralis has the surface more opaque and 
not so shining, the elytra with a slightly brownish-purple tinge, and the antenne and 
legs testaceous instead of nearly black. C. rufipes is more opaque and not of so clear a 
black ; so is C. Mexicanus, which, besides, is smaller and has black legs. 
From Columbia. 
5. CONOTELUS FEMORALIS. 
Erichs. in Germ. Zeitschr. iv. 253 (1843). 
Niger, capite, thorace elytrisque opacis, antennarum basi pedibusque testaceis, femoribus 
piceis. Long. 1$ lin., lat. 4 lin. 
Habitat in Columbia. 
Black. Antenn:e testaceous, with the first article and the club piceous. Head opaque, 
faintly rugosely punctate, bifoveolate in front. Thorax very closely and faintly rugulose, 
opaque, margined, the margin continuing along the base. Scutellum very thickly 
punctate, opaque, with the apex truncate. Elytra very closely and faintly rugulose, 
opaque, brownish purplish black, with almost imperceptible, small, flat, shallow, roundish 
surface-impressions in rows, the margin well marked. Abdomen sparingly and finely 
punctate, shining. Legs testaceous, with the thighs piceous. 
Very nearly allied to C. niger, C. vicinus, C. rufipes, and C. Mexicanus. See the remarks 
on them made under C. vicinus. 
From Venezuela. 
6. CONOTELUS RUFIPES. 
C. femorali affinis; differt thorace rugoso et haud punctato, pedibus testaceis. Long. 
12 lin., lat. + lin. 
Habitat in Mexico. 
. Nearly allied to C. femoralis, and doubtless the Mexican representative of that Colum- 
bian species; rather smaller; and chiefly to be distinguished by the thorax and elytra 
having a texture like fine morocco-leather, and the thorax without punctures or nearly 
so. Head, thorax, and elytra dull. Abdomen somewhat shining. The elytra have 
slight traces of a linear arrangement of the rugosities. Abdomen somewhat shining and 
sparsely and finely punctate ; fimbriæ broader than in most of the other species. Antenne 
rufous, with the club dusky. Legs testaceous, thighs a little darker. 
Collected by M. Sallé in Mexico.
