314 Mr. A. Murray on Coleoptera from Old Calabar. 
struck me as singular was, that these threads did not all float in 
the same direction, as though drifted from the animal by wind or 
tide, but, although they were several feet long, they formed three 
or four distinct bundles, which stretched straight out in different, 
and often opposite, directions from the body of the animal, from 
which it appeared that they were propelled by a voluntary 
effort. 
In passing through Banka Strait, owing to the number of 
rivers (Palembang and others) which flow out of the island of 
Sumatra, the water had only seven-tenths of the saltness of 
the ocean; but notwithstanding this comparative freshness, I 
observed a number of large white Rhizostomas floating just 
below the surface, apparently unaffected by this peculiar con- 
dition.

Coast of Africa. By ANpREew Murray, F.LS.

Lymexylonide. 
Atractocerus, Palis. Beauv. 
Atractocerus africanus, Boh. Ins. Caffr. i. 520. 
A single specimen. 
I have not seen any typical specimen of Boheman’s A. afri- 
canus; but mine agrees perfectly with his description, and differs 
from the well-known A. necydaloides of Latreille in the parti- 
culars which Boheman points out. “At first sight,” says he, 
“‘very similar to A. necydaloides, but is well distinguished from 
it by the head being ovate, the thorax longer, narrower, oblong- 
quadrate, and without a reflexed margin behind.” 
It would appear to range across Africa, and also into Mada- 
gascar; for I have seen specimens (probably 4. madagascariensis 
of Castelnau) from that country which did not differ from this 
Old-Calabar species. 
MeuirromMa®*, nov. gen. (See fig. 1, p. 316.) 
Hyloceeto similis, sed magnis oculis sine ocellis et thorace elon- 
gato. 
Habit and facies similar to those of Hylocwtus; the antennse 
imbricated strongly in the male, subserrated in the female; the 
palpi as in Atractocerus; the head with very large eyes, as in 
Atractocerus, covering the whole sides of the head and nearly 
* From pedurra, a bee, and dupa, an eye,—bee-eyed.
