CANATITAN COT.KOPTERA. 225 



alluded to ; and when in motion, at all events, it is next to impossible, 

 from their likeness to each other, to recognize the difference between 

 them. It is usually under the rubbish around the base of corn-stacks 

 that it is to be found ; in which positions it appeared pretty general 

 around Haria, in the north of Lanzarote, during March of 1859 ; and 

 it was only at the dose of our sojourn there, when the sun had become 

 more powerful, that I succeeded in detecting it upon flowers. My 

 Fuerteventuran specimens are principallj'' from the Eio Palmas. 



The almost testaceous hue of the A. antliicoides— which has merely 

 its head, the disc of its prothorax, its femora, the basal joint and 

 apical portion of its antennoe, and the region of its elytra about the 

 base and suture dark (the latter being only gradually obscured, the 

 two tints shading off into each other) — will immediately characterize 

 it. Its minute cinereous undcr-pile is rather denser than is the case 

 in any of the preceding species ; and its elytra, which are much less 

 shining than the head and prothorax, are of a somewhat softer texture

Its uneven prothorax, which is distinctly longer than broad, and 

 has the central portion at the base slightly raised and divided in the 

 middle (so as to form two obsciu'e nodules), and of which the extreme 

 margin at the posterior angles is usuaUtj narrowly and obscurely pale, 

 combined with the minute and somewhat longitudinally disposed sub- 

 glabrous tubercles of its elytra (the additional hairs of which are 

 very long and very erect), will easily characterize this Attalus. Its 

 colour is black, with a barely traceable metallic tinge (which, however, 

 is a little more apparent on the head and prothorax than on the 

 elytra) ; its cinereous under-pile is comparatively coarse and dense ; 

 and its limbs are rather thickened, or robust. Hitherto I have ob- 

 served it only around the Puerto Orotava in Teneriffe ; where, how- 

 ever, it is far from uncommon, during the spring months, ou flowers. 



355. Attalus obscurus. 



Attalus obscunis, WoU., he. cit. 437 (1862).
