516 CANAKIAN COLEOPTEEA. 



trorum suturam, (rarius omnino) vestita, quasi serieata. — Long. 

 Corp. lin. lf-25. 



Hahitat in Lanzarota et Fuerteventura, hinc inde ad flores. 



Although on the average a trifle smaller, the only real character, 

 that I can detect, which separates this Mordellistena from the pre- 

 ceding one is the fact of its pubescence being of a paler (or some- 

 what golden- cinereous) hue — particularly down the sutural region of 

 the elytra ; which imparts to the surface, when viewed in one direc- 

 tion, a peculiarly silken appearance. It is possible, therefore, that 

 it may be but an insular modification of the pumila ; nevertheless, as 

 it seems to obtain universally throughout Lanzarote and Fuerteven- 

 tura, whilst the ordinary form of that insect is equally constant in 

 the other islands of the Group, I am not satisfied that there is suffi- 

 cient evidence for treating it as such. In rare instances the paler 

 silken pubescence covers its entii'e surface, but it is more often con- 

 centrated merely down the suture. My examples are principally from 

 the little island of Graciosa (off the extreme north of Lanzarote), and 

 from the vicinity of OHva in Fuerteventura. 



Genus 291. ANASPIS.

Habitat insulas omnes Canarienses, ab ora maritima usque ad 9000' 

 9. m. ascendens. 



This most variable little Anasjyis, which abounds throughout the 

 Madeiran Group, is equally universal (and almost equally abundant) 

 at the Canaries — in the whole seven islands of which I have myself 

 captured it. It was found likewise by Mr. Gray in Lanzarote, Tene- 

 riffe, Palma, and Hierro ; by M. Hartung in Lanzarote ; by Dr. Crotch 

 in Teneriife, Gomera, and Palma ; and by the Barao do Castello de 

 Paiva and the late Rev. W. J. Armitage in Teneriff'e. It occurs in- 

 dependently of elevation ; for in Teneriffe I have taken it from the 

 sea-level to an altitude (on the Cumbre overlooking the Canadas) of 

 about 9000 feet, and it was met with by Dr. Crotch in the same 

 upland region. 



Its variations of colour seem, as in Madeira, endless — some ex- 

 amples being almost black, whilst others are well nigh testaceous ; 

 but, on the average, the darJcer specimens prevail more at the Canaries
