224 CANAEIAKT COLEOPTERA. 



tured and with the punctures better defined, apparently free from 

 any indications of longitudinal costse, and rather less pilose (parti- 

 cularly 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 disc dai'k. It is hitherto unique, the single 

 example from which the diagnosis was compiled having been cap- 

 tured by myself (in company with the last species and the A. clinj- 

 santhemi) in the extreme north of Lanzarote. 



352. Attains posticus. 



Attains posticus, WoU., loc. clt. 4^)4 (18G2). 



Habitat Fuerteventuram, juxta oppiduhmi Betancuriam semel 

 lectus. 



The present Attains may readily be known by its rather large size 

 and somewhat parallel outline ; by its short and depressed elytra 

 (which leave, at any rate in the female sex, a considerable portion 

 of the pygidium uncovered) ; by its large, convex, and deeply punc- 

 tured head ; by its exceedingly bright and very lightly punctulated 

 prothorax ; and by its dark hue, the hinder margin of the prothorax 

 and the extreme apex of the elytra (which are less senescent than 

 the rest of the surface) being alone of a pale whitish-yellow. It 

 was taken by myself in the Rio Palmas of Fuerteventiu-a, close to 

 the little town of Betanciuia, at the beginning of April 1859 ; and 

 is hitherto unique. 



353. Attalus anthicoides. 

 Attalus anthicoides, WolL, loc. cit. 435. pi. xx. f. 4 (1862). 



Habitat Lanzarotam et Fuerteventuram ; vel ad flores vel prsesertim 

 sub recremento farris circa basin acervorum tritici sparse, una cum 

 Anthico canariensi et cset. degcns. 



In its general outline, size, and colour this Attains bears such a 

 cui"ious2"'»"«/rtt'''e resemblance to the JLcteroma-vons Anthicns cana- 

 riensis that, until carefully examined, it might literally (although in 

 affinity so remote) be mistaken for that insect. And this analogy 

 is the more remarkable from the fact of the Jiabits of the two being 

 almost identical, — the A. anthicoides receding from the other members 

 of the group here enumerated in being found not merely upon flowers, 

 but (far oftener), like the Anthici, beneath dry vegetable refuse lying 

 upon the ground. In such situations I have captured it, rather 

 abundantly, both in Lanzarote and Fuerteventura, to which islands 

 (so far as observed hitherto) it would seem to be peculiar. In fact 

 I have frequently taken it i)i conqjany with the little ^vi^7;/fMS above
