apicalem tectis, striisque sex in partem apicalem sat profuiidis sed inter lineas 

 anastomozantes obsoletescentibus. Long. 6, lat. 3i ni.m. 



Though allied to Copelatus discoidens, this species in the female sex (which is 

 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 pimctulato ; prothorace ad latera 

 distinctius punctato ; elytris striis sex integris (sutui'ali anterius desinente) profundis, 

 aliaque marginali valde abbreviata. Long. Gi, lat. 82 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, baud 

 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. 5§, lat. Si m.m. 



The male has the front and middle tarsi a good deal dilated, and the front tibite 

 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 Aub<^ states that this species occurs in Senegal as well as in Bourbon, I 

 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 

 I am not quite sure that K lug's description of C. pulchellus really refers to this 

 species.
