436 Mr. T. V. WoUaston on the Canarian Malacoderms, 



sible, 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 end of our sojourn there, 

 when the sun had become more powerful, that I succeeded in de- 

 tecting it upon flowers. My Fuerteventuran specimens are prin- 

 cipally from the Kio Palmas. 



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

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

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

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

 two tints being shaded-ofi" into each other) — will immediately cha- 

 racterize it. Its minute cinereous under-pUe 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, or less consistent, texture. 



§ II. Prothorax cum capite elytrisque concolor (rarius ad angulos 

 ipsissimos posticos ohscurissime et anguste pallidus). 



15. Attalus tiiberculatiis, n. sp. 



A. niger, \ix submetallicus, cinereo pubescens ; capite prothoraceque 

 nitidis, minute pimctulatis, hoc subovali, iuaequali, ad basin in medio 

 sub-bituberciilato, ad angulos ipsissimos posticos ssepius angustissime et 

 obscure pallidiore ; elytris paulo minus nitidis, leviter subseriatim 

 tuberculatis, pUis nigris erectis elongatis sat dense obsitis ; antennis 

 pedibusque robustis, nigris, illis ad basin vix picescentioribus. 



Long. corp. lin. Ig-lf. 



Habitat Tenerift'am, ad flores juxta Portum Orotavse, tempore vemali 

 baud infrequens. 



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 obscure nodules), and of which the extreme 

 margin at the posterior angles is usually (though not always) nar- 

 rowly and obscurely pale, combined with the minute and somewhat 

 longitudinally disposed subglabrous tubercles of its elytra (the addi- 

 tional 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-pUe is com- 

 paratively coarse and dense ; and its limbs are rather thickened, or 

 robust. Hitherto I have observed it only around the Puerto Orotava,
