Mr. A. Murray on Coleoptera from Old Calabar. 163 
punctatis; ano producto, truncato; pedibus nigris; femori- 
bus quatuor anticis medio rubris. 
Long. 5-54 lin., lat. 1-1} lin. 
Very near Euporus viridis, Serv. (madagascariensis, Dej.), 
but narrower, of a fine golden green above, and coppery below. 
. Head. narrow, sinuate alongside the eyes, covered by a close 
punctation, longitudinal groove disappearing in front. Palpi 
black. Mandibles of an indigo-blue, passing into blackish. 
Antenne of the same colour, short, thickened towards the 
apex, grooved on the outer side, with the third article very long, 
bent and slightly angular at the top. Thorax straight in front, 
transversely wrinkled on the anterior third, with a smooth 
space neither punctured nor wrinkled behind this, constricted 
and wrinkled behind and bisinuate at the base, rounded above 
and on the sides, and coarsely irregularly punctate, the pos- 
terior part of the dorsal space being partially impunctate. 
Scutellum triangular, golden. Elytra finely shagreened, dull 
blackish green, shining on the hatte and each with two 
narrow lines of a more delicate green, one on the middle of the 
elytron, and the other on the suture. Breast and abdomen 
polished golden copper and very indistinctly punctate. Legs 
of an indigo-blue, passing into blackish; thighs abruptly and 
much thickened near the knees, four anterior thighs red on 
the swollen part; soles of the tarsi covered with a thick yel- 
lowish brush of hair. 
Appears to be rather common at Old Calabar. Aes 
I can find no difference between M. Chevrolat’s description 
of Eu. disparilis and Eu. brevicornis but that the male differs . 
from the female by having all the thighs blue-black; the 
females seem to correspond exactly. It may be that this is 
nothing more than an accidental variation ; and I treat it as 
such, with a point of doubt, in the meantime. Should it not 
be so, I am then inclined to think that M. Chevrolat has had. 
under his eyes the females of Ew. brevicornis and the male of 
a new species (disparilis), the more so that he does not include 
Euporus brevicornis in his list, although it is one of the com- 
moner species at Old Calabar, and he certainly had it from me.
