and Turner. (Individnum LinneeaDum in Musaco Linnneano baud nunc invenitur.) 
This is the species upon which the genus w^as originally estab¬ 
lished by Linnseus. Its true locality was for a considerable period 
a matter of doubt, but it is now fully established as a native of 
tropical Western Africa, whence a specimen has been lately received 
by J. Turner, Esq., by whose kindness in placing it in my hands, 
I have been enabled to clear up several points in its structure, 
incorrectly described by Afzelius. 
The head is even on its upper surface, and its front margin is 
slightly emarginate; the basal joint of the antennse is terminated 
above in pale rounded vesicular tubercles, and in a living state 
the part of the antennse bearing the four minute tubercles is 
upwards, and the curved peduncle downw^ards. The parts of the 
mouth are delineated in figures 4 a —4 e; i a being one of the 
mandibles, showing the strong muscles whereby it is moved; 4 b 
one of the maxilla^ seen from beneath, and 4 c the same with the 
base of the maxillary palpi, seen laterally, showing the absence of 
the analogue of the inner maxillary palpi; 4 d tlio labium, with 
the base of the labial palpi arising from the basal scape, and having 
the anterior extremity terminated by three points; 4 e the same 
seen laterally showing the lateral continuation of the scape, and 
the thickness of the labium ; and 4 / the posterior tarsus and the 
extremity of the tibise destitute of calcaria.
