1. Ceratolepis maculicornis, sp. n. (Tab. V. fig. 13.) 
Oblongo-ovalis, niger, elytris piceis, antennis et pedibus rufescentibus ; prothorace nitido ; elytris ‘subopacis, 
punctato-striatis, interstitiis subconvexis ad basin multipunctatis et rugosis, post medium rugulis elevatis 
et setis brevissimis in seriebus singulis asperatis. 
Long. 2°6 millim. 
Oblong-oval, black, the elytra deep piceous. Front dull, rugose, flattened, shortly pubescent; antenne 
testaceous-brown, the club a little darker, broadly obovate and spotted with minute tufts of light pube- 
scence. Prothorax about as long as broad, semi-elliptical, with indistinct apical contraction, the base 
bisinuate, without evident border; surface sparsely pubescent at sides, strongly and closely punctured, 
the punctures more or less conjoined by slight longitudinal strigee and much coarser at the sides, median 
line indistinct, not elevated, interspaces reticulate over the apical third. Elytra one-third longer than the 
prothorax, separately rounded and not margined at base, the sides slightly rounded to the posterior third, 
thence more strongly; surface rather dull, punctate-striate, the striz strong, the punctures small and 
indistinct, interstices subconvex, rugose and multipunctate before middle, thence with single series of fine 
transverse elevations bearing very short blunt sete. Underside piceous, finely rugose, and thinly 
pubescent. Legs piceous-red. 
Hab. Panama, Tolé (Champion). 
The three examples taken appear to be females. The species approaches Loganius 
flavicornis, Chap., from which it may be distinguished by the absence of carinate 
interstices towards the apex of the elytra. 
2. Ceratolepis errans, sp.n. (Tab. V. fig. 14, antenna, ¢.) 
Mas. Ovalis, piceus, prothorace partim, elytris pedibusque ferrugineis; fronte impressa, dense fulvo- villosa ; 
prothorace subtransverso, dense fortiter punctato; elytris punctato- striatis, interstitiis subconvexis, ad 
basin rugulis elevatis transyersis, in declivitate tuberculis setigeris ornatis. 
Long. 2 millim. - 
Male. Short oval. Head piceous, scarcely rostrate, front with a circular impression, tufted with dense fulvous 
hairs chiefly round the margins ; antenn testaceous, the funicular cirri moderately stout, the club infus- 
cate, rounded-securiform, pubescent, except for a small spot at the base. Prothorax subtransverse, 
bisinuate and finely margined at base, elliptically rounded at the sides; piceous or red-brown, with the 
disc infuscate, closely and deeply punctured, with a smooth spot on either side, the side-margins fine, 
crenate. Scutellum punctiform, piceous, rugose. Elytra one-fourth longer than the prothorax, rounded 
but not margined at the base; uniform red-brown, deeply striate, the strie obsoletely punctured, inter- 
stices convex, with a single series of elevated tubercles from base to apex, bearing short upright sete. 
Underside piceous-brown, coarsely punctured, the mesosternum rather prominent in front. Legs reddish, 
the third tarsal joint not evidently bilobed. 
Hab. t Mexico (coll. Blandford). 
Several examples have been sent me by M. Grouvelle, all collected in Paris from 
the refuse of Mexican tobacco. I have little doubt that it is a member of the Central- 
American fauna.
