Mr. T. V. Wollaston an the Aphanarthra of the Canaries. 167 



somewhat more pubescent surface, by its elytra being just per- 

 ceptibly less parallel, more densely sculptured, and with their 

 punctures much less evidently disposed in rows, and by its ely- 

 tral fasciae (the front one of which is simple, or at any rate less 

 clearly disjointed in the centre) being (especially the hinder one, 

 which is usually continued to the very apex) less distinct. I 

 found it tolerably common, in the decayed stems of Euph. pis- 

 catoria, in Teneriffe, Palma, and Hierro, in the last of which 

 islands it was also captured by Mr. Gray. It likewise occurs, 

 attached to the same plant, in the lower elevations of Madeira. 



8. Aphanarthrum glabrum, n. sp. 



A. fusco-nigrum, fere pilis carens ; prothorace dense alutaceo punctato, 

 antice producto leviter acuminate subincrassato (fere bituberculato) 

 sublurido ; elytris leviter subseriatim punctatis, testaceis, fasciis 

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

 etaltera angustiore subpostica) ornatis. Long. corp. lin. f-vix J. 



Habitat in ramis truncisque Euphorbiarum in ins. Hierro, rarius. 



The almost total freedom from pile (except under a high 

 magnifying power) of this little Aphanarthrum, in conjunction 

 with its very lightly sculptured elytra (the punctures of which 

 are but indistinctly disposed in rows), will, inter alia, readily 

 separate it from any of the preceding species. It appears to be 

 rare, the only specimens which I have yet seen having been 

 captured by myself in the island of Hierro. 



9. Aphanarthrum pusillum, n. sp. 



A. minutum, nigro-fuscum, pilis cinereis vestitum ; capite leviter elon- 

 gato subporrecto ; prothorace angustulo subelliptico punctato, an- 

 tice leviter producto et subito contracto acuminate ; elytris dense 

 subseriatim punctatis, concoloribus, ad humeros in tuberculum 

 indistincte elevatis ; antennis pedibusque pallidioribus. Long, 

 corp. lin. ^-vix . 



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

 riifa et Gomera, a meipso repertum. 



The excessively minute size and uniformly dark-brown hue of 

 this \\it\QAphanarthrum, in conjunction with its rather elongated 

 subporrected head and its somewhat elliptic, anteriorly contracted 

 prothorax, will at once distinguish it from any of the preceding 

 species. It is possible, indeed, that it may eventually form the 

 type of an allied genus ; but, as I have not yet attempted to 

 dissect it, or to examine its antennae microscopically, this is a 

 question I must decide hereafter. It appears to be peculiar to the 

 Euph. canariensis, in the rotten stems of which I have captured 

 it in Grand Canary (in the great crater of the Bandama), Tene- 

 riffe (on the mountains above S ta Cruz) and Gomera (on a hill- 

 summit to the northwest of San Sebastian).
