stances) both in Grand Canary and TenerifFe, in the latter of which 

 it has also been captured by the Barao do Castello de Paiva. In Lan- 

 zarote and Fuerteventm-a it was likewise met with by M. Hartimg. 

 There can be Httle doubt that it is universal throughout the archi- 

 pelago.

Though certainly distinct from it, the present Trogosita is very 

 closely related to the Madeiran T. scrrata. It is, however, a Httle 

 darker and less parallel than that insect (its prothorax being a little 

 wider in front, and the elytra a little more evidently dUated behind 

 the middle) ; its prothorax is not quite so densely punctured, more 

 coarsely margined, and straighter (though oblique) at the sides, — 

 with its anterior angles more porrect, and its extreme basal ones 

 more prominent ; its whole body is a trifle less cyHndric ; and its 

 tibiiB 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 EKphorbia-^iem. at Ye, in the north of Lanzarote, 

 during our encampment there in March 1859 ; whereas the T. ser- 

 rata has hitherto been detected only about the houses of Funchal 

 and amongst various articles of commerce, — leading to the supposi- 

 tion 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 latens ; nevertheless it may be immediately known from that in- 

 sect 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 pro- 

 thorax, by its less deeply striated elytra, and by its rather shorter 

 and less clavated antennee, — the ultimate joint particularly being 

 considerably less developed.
