ENDOPHLCEID^E. 125 



A Canarian species, apparently peculiar to TenerifFe where it is 

 widely, but sparingly, spread over the sylvan and subsylvan regions 

 of intermediate altitudes. I have taken it in the districts of the 

 Agua Mansa, Agua Garcia, and Taganana ; and it was found by 

 Dr. Crotch (and afterwards by his brother) in the garden of their 

 house at Ycocl el Alto, as well as in the Barranco below it*.

The only two examples of this Tarphius which I have yet seen 

 were taken by myself (during February 1858) in the sylvan region 

 on the western slopes of Hierro, in the Canarian Group.

Jfabitat Canarienses (Can., Ten., Palma), in sylvaticis pracsertim lau- 

 retis vulgaris. 



A strictly Canarian Tarphius, and more widely spread over the 

 archipelago than any of the other species. I have taken it in the 

 sylvan and subsylvan districts of Grand Canary, Teneriffe (where it 

 occasionally abounds), and Palma the examples from the latter 

 island differing slightly from the ordinary type, and constituting 

 what I had described (in my diagnosis) as a " var. /3." It is decidedly 

 more variable than any of the Canarian members of the genus 

 hitherto detected; for whilst most of the Tarphii are exceedingly 

 unstable in size (retaining their other features without much appa- 

 rent change), the present one fluctuates appreciably both in outline 

 and in the greater or less excavation of the posterior half of its 

 prothorax ; and it was this latter circumstance that induced me to 



* The T. dcforinis may perhaps be regarded as the representative at the Cana- 

 ries of the Madeiran T. explicatus. Nevertheless, although in their general contour, 

 greatly developed nodules, and densely scaly, wwsetose surfaces the two insects 

 have a good deal in common, they are specifically totally distinct. Thus the 

 T. deformis is much more rugosely granulated, its nodules and ridges (the latter 

 of which are almost obsolete in the explicatus) are very much more developed, 

 its prothorax and elytra are both of them relatively longer, and the former is 

 differently shaped being straighter at the sides behind (although oblique), 

 more gradually rounded anteriorly, and more deeply trisinuate along its basal 

 margin.
