 Habitat in ramis emortuis EuphorbicB 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 Ajjhanarthra 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 a])pears to be peculiar to the Euphorbia canariensis, in 

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

 mountains above 8'=^ Cruz in Teneriffe, and on a hill-summit to 

 the north-west of San Sebastian in Gomera. 



2. Aphanarthrum Juha, n. sp. 

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

 prothorace subrugoso punctate, antice producto sublurido necnon 

 ad apicem ipsum tuberculis duobus prominulis instructo ; elytris 

 suljseriatim punctatis et transversim rugulosis, testaceis, fasciis 

 duabus profunde dentatis nigris (una sc. magna in medio du})lici 

 et altera angustiore subpostica) ornatis. — Long. corp. lin. I-l^. 

 Ilahitut in ins. Lanzarota, in ramis desiccatis Euph. Regis Jubce 

 prope oppidum Ilaria 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 Jubce, at Ilaria, m the north of Lanzarote. 



3. Aphanarthrum canariense, n. sp. 



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

 thorace subconvexo alutaceo granulato, antice producto lurido 

 necnon ad apicem ipsum acuminato incrassato (fere subrecurvo) ; 

 elytris dense seriatim punctatis et transversim rugulosis, brunneo- 

 testaceis, fascia dcntata magna media nigra (plus minus sufTusa) 

 ornatis. — Long. corp. lin. j-^-
