extreme basal ones more prominent; its whole body is a trifle less 

 cylindric ; and its tibiae are less evidently pubescent along their 

 inner edge. In its habits, too, it would appear to recede from 

 that species — the unique example which has come under my 

 notice having been taken from out of a dead Euphorbia-stem at 

 Ye, in the north of Lanzarote, during our encampment there in 

 March, 1859; whereas the T. serrata has hitherto been detected 

 only about the houses of Funchal and amongst various articles of 

 commerce — leading to the supposition that it has probably been 

 accidentally introduced into the island. 



In its mode of life, indeed, the T. recta seems to be coincident 

 with the Intens ; nevertheless it may be immediately known from 

 that insect by its much smaller size, less parallel outline, and 

 reddish-brown hue (the latens being black), by its less depressed 

 upper-surface, by the straighter sides and more porrected anterior 

 angles of its prothorax, by its less deeply striated elytra, and by 

 its rather shorter and less clavated antennae — the ultimate joint 

 particularly being considerably less developed.

This insect, which is found also irt Madeira (and from the 

 characters of which I originally established the genus Europs, in 

 1854), is abundant in the dead EtipJwrbia-stems throughout the 

 Canarian archipelago, — on all the islands of which I have cap- 

 tured it, except Gomera ; though there can be but little doubt
