CANARIAN COLEOPTERA. 257 



diate Atlantic Groups, for a single example of it was found by Mr. 

 Bewicke at Ascension ; and although it was probably imported acci- 

 dentally into that island, there is nothing to warrant the suspicion 

 (but quite the reverse) that it had been brought there from either the 

 Canaries or Madeira. 



Genus 175. APHANARTHRUM. 



Wollaston, Ins. Mad. 292. tab. vi. f. 2 (1854). 

 For the diagnoses of nine out of the eleven Aphanarthra enume- 

 rated below I must refer to a Paper on the members of this curious 

 Enphorhki-micBim^ genus, published in the 'Annals of Nat. Hist.,' 

 and which I have cited under each of them ; though, at the same 

 time, the few diagnostic observations which I here add may perhaps, 

 in some instances, almost suffice, practically, for identifying them. It 

 will be seen that two of the representatives were not included in that 

 Memoir, — one of them (the A. armatum) having escaped my obser- 

 vation amongst a mass of specimens of the A. bicinctum and affine ; 

 whilst the other (the A. concolor) I had failed until recently to re- 

 cognize as an Aphamtrtlinmi at all. 



§ I. Pronotum antice productum, caput fere occultans. 

 A. Pronotum ad apicem ipsissimum tuberculis minutis armatum. 



415. Aphanarthrum Jubse. 



Aphanarthrum Jubse, JVoIl, Ann. Nat. Hist. (3rd series) v. 164 (1860). 



Habitat Lanzarotam, in ramis Eupliorbice rer/is-Jubce desiccatis 



prope oppidum Haria mense Martio a.d. 1859 sat copiose repertum. 



The comparatively large size and very long and coarse pubescence 

 of this Aphanarthrum, combined with the lurid apex of its prothorax, 

 which is armed with two tolerably distinct tubercles (besides one or 

 two smaller collateral ones) at its extreme point, and its pale-testa- 

 ceous elytra, which are ornamented with two large, black, zigzag 

 transverse fascia3 (the anterior one of which is much developed, and 

 more or less double, or looped, in the middle), wiU sufficiently cha- 

 racterize it. Hitherto I have observed it only in the north of Lan- 

 zarote, where, during March 1859, 1 captured it in considerable abun- 

 dance from out of some dried stems of the Euphorbia regis- Juhce which 

 had been piled up for burning, at Haria. 



416. Aphanarthrum armatum. 



A. nigro-fuscum, pilis bre^•ibus demissis dense vestitum ; prothorace 

 alutaceo et minute punctulato, apice producto acutiusculo vix sub-
