My. A. Murray on Coleoptera from Old Calabar. 95 
tarsi black. The head impunctate, biimpressed in front. The 
thorax rather convex, impunctate, with the disk bifoveolate 
and the sides somewhat expanded and reflexed, and impressed 
near the posterior angles, which, although acute on the great 
scale, are inflexed and rounded at the tip, the anterior angles 
obtuse and rounded at the apex; base nearly straight. Scu- 
tellum mitre-shaped. Elytra very faintly impressed with a 
series of punctures in rows; but there is a sutural line or stria 
and an anterior marginal one, both of which are pretty deep 
and strongly punctate; the sides are bisinuate, and the mar- 
gins reflexed ; the shoulders and the disk near the scutellum 
and before the middle, and the disk behind the middle, all 
separately raised into prominences. Beneath fulvo-pubescent, 
the pubescence longest on the metasternum. Abdomen rather 
flat and somewhat soft. 
This species looks exceedingly like some of the tropical 
Gallerucide, as Agelocera, Rhombopalpa, &e. It does not 
appear to have been common, a few specimens only having 
been received. 
Elateride*. 
APHANOBIUS, Esch. 
Aphanobius seclusus, Cand. Elat. iv. p. 322. 
Several specimens received. 
The genus Aphanobius has hitherto been supposed to be 
peculiar to the Kast. ‘Ten species are described by Candeéze. 
Of these, four are from the Mauritius and five from other parts 
of the Indo-Malayan district—Singapore, Java, India, China, 
&c.; the occurrence of the only other species (the present) at 
Old Calabar is, as I think, an evidence either of a connexion be- 
tween Africa and India, or else of a great geological antiquity 
of the generic form. The presence of many other Indian 
forms in Africa makes the former the more probable explana- 
tion; and the greater diffusion of such Indian forms would 
seem to indicate that the connexion was probably of a much 
older date than that which seems to have existed between the 
west coast of tropical Africa and the opposite coast of Brazil. 
Craronycuust, Boisd. & Lacord. 
Cratonychus umbilicatus, Gyll., Cand. Elat. ii. p. 322. 
This is the only species in the large genus Cratonychus 
* All the Elateride which I had then received from Old Calabar were 
placed by me in Dr. Candéze’s hands at the time he was engaged on his 
great work on that family, and were therein described. A few additional 
species have since been received. 
+ Ido not agree with my friend Dr. Candéze in his reasons for aban- 
doning the old name Cratonychus and substituting Melanotus.
