852. Copelatus striatulus, Aubé, M.C.—Oblongo-ovalis, sat angustus, subde- 
pressus, sat nitidus, piceus, elytris nigricantibus, antennis pedibusque rufis; fere 
impunctatus; elytris striis quinque elongatis, stria marginali valde abbreviata,

A single female in my own collection agrees exactly with the type (in very bad 
condition) of this species from Chevrolat’s collection in the Brussels Museum. 
Africa, (Senegal). 690. 
853. Copelatus latipes, n. sp.—-Oblongo-ovalis, latiusculus, subdepressus, sat 
nitidus, piceus, elytris nigricantibus, antennis pedibusque rufis ; subtiliter punctatus, 
prothorace ad latera sat fortiter punctato; elytris striis quinque elongatis, stria 
marginali valde abbreviata, aliaque suturali ad apicem tantum exstante; prosterno 
medio mediocriter compresso-carinato. Long. 6, lat. 3 m.m. 
The male has the front and middle tarsi rather broadly dilated; the front tibize 
are very abruptly bent below the knee, the basal part being slender and bisinuate 
on the inner edge, while the apical portion is broad. The female I do not know. 
Malacca. 691. 
854. Copelatus pusillus, n. sp.—Oblongo-ovalis, sat clongatus, angustulus, subde- 
pressus, piceus, supra magis nigricans, marginibus (preesertim elytrorum lateribus) 
dilutioribus, antennis pedibusque rufo-testaceis; obsolete punctatus, prothorace ad 
latera ante angulos posteriores area parva strigulosa; elytris striis subtilibus sex, 
aliaque marginali brevissima, striis prima et externa anterius desinentibus. Long. 
+, lat. 27 m.m. 
The male has the front and middle tarsi somewhat broadly dilated, the front 
tibize are curved, the basal portion being very slender, and much emarginate below 
the knee: the female shows no difference in sculpture from the male.

latera strigulis parcissimis brevissimisque; elytris striis sex sat profundis et fere 
integris, aliaque marginali brevissima. Long. 5, lat. 2? m.m. 
The very few scattered and distant scratches on the thorax are inconspicuous, 
sometimes in fact nearly entirely absent, the striz on the elytra are all continued 
nearly to the base, the internal and the cuter ones being only very slightly
