 extinction. 



With respect to the minor generic details of this curious insect, 

 space forbids me to comment on them, — so I must merely refer to 

 the diagnosis. I may just add, however, that it differs inter alia, 

 from Pentatemnus in having its scutellum distinct and its elytra 

 free, in its four anterior legs being approximate at their base, 

 and in the remarkable confirmation of its antennae (19, 2 a), — 

 the scape of which (as already stated) is so minute as to be quite 

 buried in the sm.all scrobs, or auriculiform fovea, in which it is 

 implanted ; whilst the funiculus is 6-articulate (the first two 

 joints being very large and thick, and the remaining four short 

 and small) ; and the capitulum most densely pilose towards its 

 apex.

Habitat insulas Fuerteventura et Gran Canaria, in locis simi- 

 libus ac Pentatemnus arenarius et una cum illo degens, sed multo 

 rarior : ad radices Zygophyllum Fontanesii prope Puerto de 

 Cabras Fuerteventurae sat frequens, necnon inter urbem Las 

 Palmas et viculum Puerto de Luz, Canariaj Grandis, exemplar 

 unicum cepi. 



Occurs at the roots of shrubby plants, in company with the 

 Pentatemnus arenarius, but very much rarer. In the sandy region 

 to the south of Puerto de Cabras, of Fuerteventura, it was taken 

 sparingly, both by myself and Mr. Gray; and I found a single 

 specimen of it in Grand Canary, on tlie sandy isthmus (between 

 Las Palmas and Puerto de Luz) which connects the Isleta with 

 the mainland.
