a much smaller portion at the apex, and also the entire lateral 

 margin (instead of only half of it) pale ; and its paler parts are 

 altogether of a duller or browner tint. The few specimens which 

 I have seen (five in number) were captured by mj^seK from off the 

 flowers of the Euphorbia piscatoria and halsamifera, on the lofty 

 cliff's known as the "Risco" (overlooking the Salinas), in the ex- 

 treme north of Lanzarote. They are all of them females ; but, 

 from their general aspect and their manifest affinity with the last 

 species, there can be no doubt that they are correctly referred to the 

 present genus. 



12. Attains Icevicollis, n. sp. 



A. antice subacuminatus, niger, prothorace (macula media magna excepta),

 profunde rugoso-punctatis, antice subcalvis, postice pilis nigris erectis 

 longiusculis parce obsitis, margine laterali postice paido dilutiore.

In general character and outline, the present species somewhat 

 resembles the last one. It is however larger, with its head and 

 prothorax very highly polished and almost entirely impunctate (a 

 few extremely minute and remote points being alone traceable even 

 beneath the microscope) ; its elytra are blacker, more coarsely sculp- 

 tured, and with the punctures better defined, apparently free from any 

 indications of longitudinal costae and rather less pilose (particularly 

 in front); and its pale portions are altogether of a much lighter 

 yellow, — the prothorax, moreover, having merely a broad central 

 band on its fore disk dark. It is hitherto unique, — ftie single ex- 

 ample (a female) from which the above diagnosis has been compiled 

 having been captured by myself, in company with the last species 

 and the A. chrysanthemi, in the extreme north of Lanzarote.
