into a narrow rim, which merges into an obtusely-curved hook at 

 the tip) ; whilst the latter has its inner apical-angle produced into 

 a long and acute spine, which, being outwardly-directed, gives 

 that portion of the leg a very singular appearance. The insect 

 on which I have erected the genus is as remarkable in its habits 

 as it is in its structure, — being confined exclusively (so far as I 

 have hitherto observed) to the moist and rott'wg Euphorbia -stems 

 throughout the various Islands of the Canarian archipelago, re- 

 siding principally at the lojver portions of them, where they come 

 in contact with (and are often buried in) the damp earth.

This insect is probably universal, in the rotten Euphorbia-stems, 

 throughout the Canarian archipelago ; nevertheless, up to the 

 present time, I have taken it in only five islands out of the seven, — 

 namely, Lanzarote, Fuerteventura (and even on the small adjacent 

 rock of Lobos), Grand Canary, TenerifFe and Hierro. It was 

 first captured by myself and Mr. Gray on the Risco (above the 

 Salinas) in the north of Lanzarote, during January, 1858; but I 

 took it in much greater abundance, subsequently, in the Euphorbia- 

 grounds near Orotava of Teneriflfe, and in the lower district of El 

 Golfo, on the west of Hierro.
