times infuscated in parts, should perhaps be described as testaceous 

 rather than strictly yellow. Its sui-face is also very densely and 

 rather coarsely sculptured, particularly the head and prothorax, 

 which are less shining than the elytra ; and its antennae are black, 

 with the basal joints more or less obscurely rufo-testaceous. That 

 it is the species referred in M. Hartung's list to the AntJiocomus 

 analis, Panzer, I am enabled to state for certain, having received 

 examples thus identified from Dr. Heer, who compiled it. It does 

 not possess, however, a single feature, either of size, outline, colour, 

 clothing, or sculpture, in common with that insect. In very rare 

 cases the large yellow portion at the apex of the elytra is much 

 reduced both in dimensions and intensity, when the legs also are 

 apt to be almost, or even entirely, dark. It is such specimens as 

 these (which however can be connected gradually with the others) 

 which I have defined above as the " var. /3." 



So far as observed hitherto, the A. chrysanthemi 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 Chrysanthemum 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, in 

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

 during 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. chrysanthemi. 

 It is, however, less depressed, and more acuminated anteriorly ; its 

 surface, instead of being cyaneous-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 pronotum 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 longitudinally costate) have
