PHALACRID^E. 



This common European insect is universal (at low and interme- 

 diate elevations) at the Canaries in the whole seven islands of which 

 it has been taken, more or less abundantly. But although thus 

 general at the Canaries, it is somewhat remarkable that it has not 

 yet been detected in the Madeiran Group.

Habitat Maderenses (Mad.}, in locis editioribus rarissimus ; floribus 

 Cinerarice auritce (Senecionis maderensis, De Cand.) ad rupes 

 excelsas praBcipue gaudet. 



Apparently peculiar to the lofty sylvan districts of Madeira proper, 

 where, however, it is extremely rare, infesting the flowers of the 

 Cineraria aurita, the large clusters of which are so conspicuous on 

 the damp rocks of a high altitude. 



291. Olibrus florum. 

 Olibrus florum, Woll., Cat. Can. Col. 106 (1864). 



Habitat Canarienses (Can., Ten., Gom., Palma, Hierro], praesertim 

 super flores Cinerarice in intermediis hinc inde vulgaris. 



A Canarian Olibrus, with much the same habits as the preceding 

 one in Madeira infesting the flowers of a large and pale Cineraria 

 (quite distinct from the Madeiran plant) at intermediate elevations. 

 It has been detected in all the islands of the Group except the two 

 eastern ones, Lanzarote and Fuerteventura appearing to become 

 gradually commoner as we approach the west. And, accordingly, 

 in Hierro, the most western of them all, I have seen the Cinerarias 

 around Yalverde absolutely teeming with it. In Gomera it was 

 taken, during the summer of 1864, by the Messrs. Crotch. It has 

 very much the colour and aspect of the European 0. corticalis ; 

 nevertheless I believe that its true affinities are rather with the 

 Madeiran cinerarice than with that species.
