Though allied to Copelatus discoideus, this species in the female sex (which 1s 
the only one I know), is readily distinguished by the great extent of the dark colour 
on the elytra, by its rather more elongate oval form, by the scratched surface of 
the elytra, and by the entire absence of the marginal stria.

863. Copelatus africanus, n. sp.—Ovalis, sat elongatus, vix angustulus, sat 
depressus, piceus, capite anterius prothoracis elytrorumque lateribus ferrugineis, 
antennis pedibusque rufis; capite subtiliter punctulato; prothorace ad latera 
distinctius punctato ; elytris striis sex integris (suturali anterius desinente) profundis, 
aliaque marginali valde abbreviata. Long. 64, lat. 32 m.m. 
I have seen but a single male individual of this species which has lost most ot 
its tarsi, the front ones appear to be moderately dilated, and the front tibia is 
rather broad, and a little curved at the knee.

864. Copelatus pulchellus, Klug, M.C.—Oblongo-ovalis, latiusculus, haud 
elongatus, subdepressus, piceus, capite anterius, prothoracis lateribus elytrisque 
rufescentibus, his disco plus minusve infuscato, basi discrete dilutiore, antennis 
pedibusque rufis; thorace ad angulos posteriores strigoso-punctato ; elytris striis sex 
profundis, suturali prope scutellum desinente, aliaque marginali valde abbreviata. 
Long. 53, lat. 3g m.m. 
The male has the front and middle tarsi a good-deal dilated, and the front tibive 
a good deal curved, the basal portion being rather deeply bisinuate inwardly, the 
lower part of the tibia is broad: the female has a very few, not easily detected, 
scratches about the middle of the elytra. 
Though Aubé states that this species occurs in Senegal as well as in Bourbon, [ 
am inclined to think that the few specimens (in very bad condition) which I have 
seen from the former locality indicate one or two distinct allied species : I have also 
seen in the Brussels Mus. collection a specimen of a variety or closely allied species 
said to be from Cuba, and have another in my own possession said to be from N. 
America, but I consider confirmation is wanted of these localities. I may add that 
Tam not quite sure that Klug’s description of C. pulchellus really refers to this ~ 
species.
