450 CANARIAN COIEOPTERA. 



the insect from which the above characters have been drawn is truly 

 distinct from Tentyria — its external peculiarities being more than 

 sufficient to render its isolation therefr'om not only desirable, but 

 necessary. Its two main differential features consist in its scuteUum 

 being excessively short and transverse (constituting in fact, as in He- 

 geter, a mere portion of the marginal rim at the base of the elytra), 

 and in its surface being sparingly studded with long and erect hairs. 

 In other respects, its epistome is much produced, and acute, in the 

 centre ; the terminal joint of its antennae is considerably smaller than 

 the preceding one, and obliquely truncated at the apex ; its prothorax 

 (which is wide anteriorly and narrowed behind) is somewhat bisinu- 

 ated along the basal edge, and has the posterior angles well defined 

 ami rather acute ; the humeral angles also of its elytra are sharply 

 defined by the greatly thickened marginal rim ; its entire surface is 

 irregularly punctured (the punctui'es, which are very variable in size, 

 being composed of a double series — large and small) ; and its limbs 

 are thickened and pilose.

Habitat Lanzarotam et Fuerteventuram, necnon in insulis parvis 

 adjacentibus (sc. Graciosa et Lobos), sub lapidibus vulgaris. 



A universal insect throughout Lanzarote and Fuerteventura (and 

 the adjacent islands of Graciosa and Lobos), occurring beneath stones. 

 I do not believe that it exists further westward in the archipelago ; 

 for although I have received it from Paris as Teneriifan, it was pro- 

 bably regarded as such through the mere fact of its having been sent 

 from Teneriffe (even whilst obtained elsewhere in the Group). It 

 was captured likewise by Mr. Gray and M. Hartung; and from 

 Fuerteventura it has been communicated by the Barao do CasteUo de 

 Paiva, to whom I have had much pleasure in dedicating the genus.
