than in Madeira. Nevertheless the following observations, from my 

 ' Ins. Mad.,' are nearly as a^iplicable here as in the neighbouring 

 Group. '' So great are the changes of hue through which it passes, 

 that at first sight it would seem to vary from a uniform testaceous 

 into a deep black. Such, however, is not in reality the ease (as a 

 closer examination will prove), seeing that in the palest specimens an 

 obscurer portion along the suture, an ill-defined cloud at the base, 

 and a sublateral dash towards either side (representing the transverse 

 medial band) are usually more or less present on the elytra, and there 

 are often the rudiments of a patch on the prothoracic disc ; whilst even 

 in those extreme varieties where these darker portions are so increased 

 in size as to occupy nearly the entire surface there are generally faint 

 indications of four subrufescent elytral blotches, which at once enable 

 us to identify them with the rest."

This elegant insect, so remarkable for its clear rufo-ferruginous 

 prothorax and limbs, black head, viridi-cyaneous elytra, and shining, 

 pilose surface, appears to be of the greatest rarity in these islands — 

 the only two examples which I have seen having been captured by 

 myself, on the 14th of April 1858, by brushing the short grass at the 

 edges of one of the freshwater pools (close to the sea) at Arguiniguin, 

 in the south of Grand Canary. It is recorded by La Ferte from Algeria 

 and the south of Spain ; and indeed I possess a specimen which was 

 taken by the Eev. Hamlet Clark at Malaga.
