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



by its pale whitish-testaceous hue, diaphanous (or subhyaline), 

 slightly shining, almost unpubescent, and most lightly punctured 

 surface, and by the quantity of dark patches and broken fasciae 

 with which it is ornamented. It occurs in the dead branches of 

 (I believe principally) the Euph. piscatoria, under which circum- 

 stances it was taken by myself in Teneriffe and Palma, arid by 

 Mr. Gray and myself in Hierro. I have likewise captured it, 

 from out of the stems of the same plant, in Madeira, where, 

 however, the specimens have their elytra a trifle more distinctly 

 punctured, and the interstices somewhat more roughly aluta- 

 ceous, or shagreened. 



6. Aphanarthrum affine. 



A. angustulum, fusco-nigrum, pilis suberectis sat dense vestitum ; pro- 

 thorace alutaceo punctato granulate, antice producto lurido nec- 

 non ad apicem ipsum leviter acuminate incrassato ; elytris seriatim 

 punctatis, testaceis, fasciis duabus profunde dentatis nigris (una 

 sc. magna in medio duplici et altera angustiore subpostica) orna- 

 tis. Long. corp. lin. f-vix J. 



Habitat in ramis emortuis Euphorbiarum in ins. Lanzarota, Fuerte- 

 ventura et Canada, hinc inde frequens. 



This species and the following one are a good deal allied; the 

 A. affine, however, is rather larger and a little less densely 

 pubescent, and its elytra are somewhat more parallel and less 

 closely sculptured, the punctures being more evidently arranged 

 in rows than is the case with the A. piscatorium. Its elytral 

 fascise, also, are much more distinct; and the anterior one is 

 more decidedly double in its central region, like that of the 

 A. Juba, bicolor, and glabrum. It was taken abundantly by 

 Mr. Gray and myself, out of the Euph. balsamifera, in the north 

 of Lanzarote, and by myself at Betancuria in Fuerteventura, as 

 well as (out of the E. piscatoria] at El Monte in Grand Canary. 

 It is a good deal allied, in general facies, to the Madeiran A. 

 Euphorbia ; nevertheless it is slightly smaller than that insect, 

 its pubescence is longer, its prothorax less acuminated in front, 

 and its elytral punctures are much larger, fewer, and more 

 evidently disposed in rows. 



7. Aphanarthrum piscatorium, n. sp. 



A. fusco-nigrum, pilis suberectis dense vestitum ; prothorace alutaceo 

 dense punctato, antice producto leviter acuminate sublurido ; ely- 

 tris dense subseriatim punctatis et transversim rugulosis, dilute 

 testaceis, fasciis duabus profunde dentatis nigris (una sc. magna et 

 altera angustiore suffusa postica) ornatis. Long. corp. lin. f-f . 



Habitat in ins. Teneriffa, Palma et Hierro, in ramis E. piscatorice 

 emortuis, ubique vulgare. 



A rather insignificant little species, closely allied to the last 

 one. It may be known from it, however, by its smaller size and
