the base. The elytra are scarcely wider than the 

 base of the thorax, deeply grooved near the suture, 

 and marked with punctured lines on the sides, each 

 of them with two narrow lines of reddish yellow. 

 The anterior thighs are furnished with a small tooth 

 on the under side. Like all the other species of the 

 genus, this insect lives under bark, and is often found 

 on the stems of old trees congregated in hundreds. 



RHINA BARBIROSTRIS.

 culio barbirostris, Fabr. 



The species given as an example of this genus — 

 which may be briefly characterised by the elongate 

 shape of the terminal joint of the antennae, and the 

 length of the fore legs — is found at the Cape of 

 Good Hope. It is entirely of a black colour, ex- 

 cept the hairs on the rostrum, which are reddish 

 yellow. The rostrum or snout is longer than the 

 thorax, trifid at the point, and tuberculated above. 

 The thorax is rough with deeply impressed punc- 

 tures, and bears yellowish hairs on the sides and 

 beneath. The elytra are marked with closely placed 

 lines of deep square punctures, the spaces between 

 which have a few short hairs. The anterior legs 

 are much longer than the others, and all the tibiae 

 are armed with a few remote spines.
