Habitat Canarienses (Lanz., Fuert.), foliis Mercurialis annuce nisi 

 fallor praecipue gandens. 



A small and rather insignificant Psylliodes which has been cap- 

 tured hitherto only in Lanzarote and Fuerteventura, the eastern 

 islands of the Canarian Group, where I believe that it is principally 

 attached to the common Mercurialis annua.

Habitat Madererises (Mad., P to S to , Des.} et Canarienses (ins. omnes),

There can be little doubt that this Psylliodes is universal through- 

 out these Atlantic Groups. Indeed I have myself captured it in all 

 the Madeiran islands except the northern and southern Desertas, 

 as well as in the whole seven of the Canarian archipelago. Yet 

 although thus general, it has somewhat the appearance of being an 

 introduced species occurring for the most part in and about cul- 

 tivated spots, where it attaches itself principally to certain plants of 

 the Sinapis-tribe* . 



1025. Psylliodes vehemens.

Habitat Maderenses (Mad., P to S to , Des.) et Canarienses (ins. omnes),

* Unless the P. hospes be but a geographical modification of the cuprea, Illig., 

 of more northern latitudes, the fact of its being distinct from every European 

 species hitherto recorded would certainly militate against the hypothesis that it 

 was introduced originally into these Atlantic islands. It is possible therefore 

 that it may be truly aboriginal, but attached to some of the indigenous members 

 of the Cruciferce.
