CANARIAN COLEOPTERA. 223 



even entirely, dark. Such specimens as these (which however can 

 be connected gradually with the others) I defined, in my diagnosis, 

 as the "var. (5. dasi/toides.'" 



So far as observed hitherto, the A. clirysanthemi appears to be 

 peculiar to Lanzarote and Fuerteventura, where it occurs on the 

 flowers of various plants during the winter and spring, though more 

 particularly those of the Chrysanihemwm ochroleucum of Webb and 

 Berthelot. In such situations it was taken abundantly by Mr. Gray 

 and myself, between Haria and Magui, in the north of Lanzarote, 

 diiring January 1858 ; as also subsequently, by myself, in the same 

 locality, diiring March of the following year ; and, a few weeks later, 

 at Oliva, in Fuerteventura.

This Attains is apparently a good deal allied to the A. chrysan- 

 tJiemi. It is, however, less depressed, and more acuminated an- 

 teriorly ; its surface, instead of being C5^aneous-green, is dark- 

 aeneous, with the entire margins of the prothorax (and not merely the 

 posterior one) of a dull fulvous-yellow ; its head and i^ronotum are 

 narrower, much more shining, and very much less sculptured (the 

 former being almost impunctate, whilst the punctures of the latter 

 are exceedingly shallow and ill-defined) ; its elytra (which have, 

 especially towards the suture, obscure indications of being longitu- 

 dinally costate) have 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 spe- 

 cimens which I have seen (five in number) were captured by myself 

 from off the flowers of the EupJiorbia piscatoria and bahamifera, on 

 the lofty cliffs known as the " Eisco " (overlooking the Salinas), in 

 the extreme north of Lanzarote.

In general character and outline the present species somewhat 

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

 thorax 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-
