There is a single specimen of this genus, a. $, 12 mm. long. It is very small indeed 

 for T. trimcatus, but by comparison with that and other species in the British Museum 

 I have not been able to find any structural character separating it from T. truncatus. 

 The specimen is dark reddish-brown and strongly shining ; the frontal plate is transverse, 

 with a slight transverse carina on its lower (anterior) part, and with its upper border 

 rounded and bearing a very obsolete tubercle at the summit ; the thorax is quite 

 impunctate, with a well-marked rounded median depression anteriorly (but with no 

 tubercle behind this depression), and with the posterior portion very slightly depressed 

 medially. 



From its small size and general form this specimen bears a strong superficial 

 resemblance to the W. African 7'. repandus, which species however is at once dis- 

 tinguished by its tall narrow frontal plate emarginate at the summit.

14 males, 11 females, from cultivated places; the larvte are found in decaying stems 

 of coconut-palms. This sj)ecieK (locally spoken of as " boeuf banane ") is stated to be 

 injurious both to coconut trees and bananas (see Kolbe, I.e.). There is gi*eat variation 

 in both sexes in actual size, in relative proportion of lengtli to breadth, etc.
