MALACHIADA. 201 



and western islands of the Canarian archipelago, occurring from the 

 sea-level to an altitude of at least 8000 feet. It has been captured 

 in Grand Canary, Teneriffe (where it often abounds at a lofty eleva- 

 tion on the blossoms of the Retama), Gomera, and Palma ; and we 

 may consequently expect to meet with it in Hierro likewise. 



The A. cenescens varies a little in sculpture the examples from 

 the higher altitudes of Teneriffe (where it abounds on the blossoms of 

 the Retama) being a little more sparingly and strongly punctured, 

 as well as somewhat more polished and with their heads just percep- 

 tibly rounder and more developed ; but I do not think that they 

 have the slighest claim to be regarded as distinct from those which 

 are found in the less elevated districts. Nevertheless that particular 

 state is the one which I took as my type of the species ; and if there- 

 fore the rather more closely punctured form (which occurs not only 

 in Teneriffe, but in Gomera and Palma likewise) should at any future 

 time have to be separated (which I cannot but regard as extremely 

 improbable), it must stand under the name of puncticollis which I 

 applied to it, treating it as a " var. /5," in my diagnosis.

Peculiar to the Madeiran Group, where most probably it will be 

 found to be quite universal, though it is evidently far more abun- 

 dant in Madeira proper than elsewhere. It occurs principally in the 

 higher elevations, and has been detected hitherto in Madeira proper, 

 Porto Santo, and the southern Deserta (or Bugio). In the sylvan 

 districts of Madeira proper it is very partial to the flowers of the 

 Cineraria aurita (the Senecio maderensis of De Candolle), the large 

 clusters of which often teem with it. Judging from the examples 

 which I have yet taken, the species would appear to be much smaller 

 in Porto Santo and the Bugio than it is in Madeira proper, a fact 

 however which is rendered quite intelligible from the comparatively 

 exposed and weather-beaten nature of those two islands. Indeed 

 the only spot where I have observed it in Porto Santo is the extreme 

 summit of the Pico Branco ; and on the southern Deserta I met 

 with it, in like manner, on the very top of that remote and almost 

 inaccessible rock.
