Coleoptera of the Canary Islands. 167 



lowing one differ from the other Aphanarthra here described. 

 The A. luridum may be known by the pale lurid-testaceous hue of 

 its entire upper-surface, with the exception of a longitudinal dash 

 on each of its elytra, and the dorsal line of its prothorax (together 

 with a spot on either side of the latter, and a suffused portion in 

 front), which are alone more or less dark. Its prothorax is very 

 much less produced over the head than in the other species, its 

 punctuation is extremely fine and minute, and its elytra are per- 

 ceptibly shortened, or obliquely truncated, at their apex. It ap- 

 pears to be peculiar to the Euphorbia canariensis, in the rotten 

 stems of which I have taken it plentifully on the mountains above 

 Santa Cruz of Teneriffe, and on a hill-summit to the north-west 

 of San Sebastian in Goraera.

(I860).' 

 Habitat in ins. Lanzarotcl, in ramis dessicatis Euph. Regis-Juhce 

 prope oppidum Haria a meipso a. d. 1859 copiose repertum. 



The extremely pubescent surface of this large species, in con- 

 junction with the small but distinct tubercles in the middle of the 

 anterior edge of its prothorax (the two central ones of which are 

 very evident), will, apart from its colouring as defined above, at 

 once characterise it. It was detected by myself, during March of 

 1859, in great abundance, amongst a pile of dried stems of the 

 Euph. Regis-Jubce, at Haria, in the north of Lanzarote. 



20. Aphanarthrum armatum,* n. sp. 



A. nigro-fuscum, pilis brevibus demissis dense vestitum ; pro- 

 thorace alutaceo et minute punctulato, apice producto acu- 

 tiusculo vix sublurido et ibidem tuberculis duobus spini- 

 formibus porrectis subapproximatis instructo ; elytris dense 

 sed leviter subseriatim punctatis, fascia magna transversd 

 testacea mox pone basin ornatis ; antennis pedibusque in- 

 fuscato-testaceis.
