128 ENDOPHLCEID^E. 



This singular Tarpldus is also a Teneriffan one, and confined (so 

 far as I have observed hitherto) to the sylvan mountains in the north- 

 east of the island where, although local, it is not very uncommon.

Habitat Canarienses (Ten.), in sylvaticis intermediis praDsertim pine- 

 tis hinc inde vulgaris. 



The T. congests seems to be characteristic of the pine-regions of 

 Teneriffe, though occasionally found in spots where the fir trees and 

 the laurel grow together. Its true habitat, however, is clearly the 

 Finals ; for although I took it sparingly (during 1858 and 1859) at 

 the Agua Mansa, where the various laurels and the Pinus canariensis 

 are intermixed, the Messrs. Crotch have subsequently met with it in 

 profusion throughout the great Final which clothes the mountain - 

 slopes above Ycod el Alto, and which continues thence (almost with- 

 out intermission) to within a short distance of Ycod de los Yinhos. 



368. Tarphius simplex.

Habitat Canarienses (Ten.), in sylvaticis parum vulgaris. 



The T. simplex, which is likewise Canarian, seems peculiar to the 

 laurel-regions of Teneriffe where it is pretty generally distributed, 

 and occasionally common.

Habitat Maderenses (Mad.), semel tantum capta. 



A single example captured near Funchal in Madeira proper by 

 the late Mr. Bewicke, is all that I have yet seen of this curious in- 

 sect (the structural characters of which are a good deal in accordance 

 with those of the European genera Pycnomerus and Xylolcemus). 

 Whether it be of Euphorbia -infesting habits I am unable to say ; but
