Habitat Canarienses (Lanz.), intra caules Euphorbiarum parce lectum. 



The only two examples which I have seen of this species were 

 taken by myself, out of Euphorbia -steins, in Lanzarote of the 

 Canarian Group. Apart from colour, they differ from their immediate 

 allies in having their elytra somewhat less parallel and more finely 

 punctured, the punctures being less evidently disposed in longitudinal 

 rows, and in their prothorax being a little more produced at the 

 apex (where it is armed with much larger tubercles, the inner pair 

 of which are elongate and porrect) and rather more carinated behind. 

 Their pubescence, which is soft and very dense, appears on the elytra 

 to be pale and nearly decumbent.

Aphanarthrum canescens, Wott.j Append, AM/, op. 41. 



Habitat Canarienses (Can., Gom.), in ramulis Euphorbiarum a DD. 

 Crotch lectum. 



Taken abundantly in Gomera by the Messrs. Crotch, and also near 

 Las Palmas in Grand Canary, the specimens from the latter island 

 differing in having their minute prothoracic pustules usually obsolete.

Habitat Canarienses (Can., Ten., Gom., Palma, Hierro), plantas 

 phorbiarum putridas praecipue E. canariensis destruens. 



Widely spread over the Canarian archipelago, in all the islands of 

 which I have taken it except Lanzarote and Fuerteventura. It seems 

 to be attached principally (perhaps entirely) to the rotten stalks of 

 the Euphorbia canariensis ; but as that plant, I believe, does not now 

 occur in the two eastern islands of the Group, the species probably 

 will not be found in either of them. 



677. Aphanarthrum pygmaeum. 



Aphanarthrum pygmaeum, Woll., Append, huj. op. 4.2.
