164 Mr. T. V. Wollaston on the Aphanarthra of the Canaries. 



prothorace sublsevi punctulato, antice minus producto nigrescente, 



linea dorsali et stigmate utrinque posito plus minus nigrescentibus ; 



elytris leviter seriatim punctulatis et transversim rugulosis, pos- 



tice leviter truncatis, plaga discali nigrescente (in singulo posita) 



ornatis. Long. corp. lin. 1. 

 Habitat in ramis emortuis Euphorbia canariensis in ins. Teneriffa 



et Gomera, hinc inde frequens. 



In their somewhat larger size, the present species and the 

 following 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 pro- 

 thorax is very much less produced over the head than in the 

 other species, its punctation is extremely fine and minute, and its 

 elytra are perceptibly shortened, or obliquely truncated, at their 

 apex. It appears to be peculiar to the Euphorbia canariensis, in 

 the rotten stems of which I have taken it plentifully on the 

 mountains above S ta Cruz in Teneriffe, and on a hill-summit to 

 the north-west of San Sebastian in Gomera. 



2. Aphanarthrum Jubte, n. sp. 



A. fusco-nigrum, pilis longis subdepressis mollibus dense vestitum ; 

 prothoraee subrugoso punctate, antice producto sublurido necnon 

 ad apicem ipsum tuberculis duobus prominulis instructo ; elytris 

 subseriatim punctatis et transversim rugulosis, testaceis, fasciis 

 duabus profunde dentatis nigris (una sc. magna in medio duplici 

 et altera angustiore subpostica) ornatis. Long. corp. lin. 1-1 . 

 Habitat in ins. Lanzarota, in ramis desiccatis Euph. Regis Jub<z 

 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 characterize it. It was detected by myself, during 

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

 of the Euph. Regis Juba, at Haria, in the north of Lanzarote. 



3. Aphanarthrum canariense, n. sp. 



A. latiusculum, fusco-nigrum, pilis brevissimis parce vestitum ; pro- 

 thorace subconvexo alutaceo granulate, antice producto lurido 

 necnon ad apicem ipsum acuminate incrassato (fere subrecurvo) ; 

 elytris dense seriatim punctatis et transversim rugulosis, brunneo- 

 testaceis, fascia dentata magna media nigra (plus minus suffusa) 

 ornatis. Long. corp. lin. f J-. 



Habitat in ramis putridis Euph. canariensis in ins. Canaria, Tene- 

 riffa, Gomera, Palma et Hierro, vulgare.
