126 CANAPaAN COLEOPTERA. 



referred to). Hitherto I have observed the T. erosus only in the 

 laurel-woods towards the north-eastern portion of Teneriife, — where, 

 at Las Mercedes, as also above Taganana and Point Anaga, it occurs, 

 not uncommonly, in company with the last species. 



210. TarpMus quadratus. 



Tai-jihius quadratus, Woll, loc. cit. 384. pi. 19. f. 5 (1862). 



Habitat in lauretis editioribus Palmae, rarissimus. 



This broad and comparatively square Tarpldus is apparently of the 

 greatest rarity, and confined (so far as I have observed hitherto) to 

 the laurel-regions of Palma, — where, during May and June of 1858, 

 I captured it from beneath sticks and small pieces of wood on the 

 ascent to the Cumbre above Buenavista, and towards the upper part 

 of the Barranco de Galga. 



211. Tarphius congestus. 

 Tai-phius congestus, Woll, loc. cit. 385. pi. 19. f. 6 (1862). 



Habitat in lauretis et pinetis Teneriflfe, rarissinuis. 



Likewise extremely rare, the only region in which I have hitherto 

 captured it being that of the Agua Mansa of TenerifFe, — where I took 

 it sparingly diu-ing May of both 1858 and 1859, not merely in the 

 laurel- woods, but also amongst the ^/--plantations on the ascent to 



the Cumbre. 



212. TarpMus gigas. 

 Tarphius gigas, Woll, loc. cit. 386. pi. 19. f. 7 (1862). 

 Habitat Teneriffam, in sylvaticis rai-issimus. 



Two specimens only of this comparatively gigantic Tarpliius have 

 as yet come beneath my notice. They were both of them captured 

 in the laurel-woods on the mountains between Taganana and Point 

 Anaga, during May of 1859. 



213. Tarphius caudatus. 

 Tarphius caudatus, Woll, loc. cit. 386. pi. 19. f. 8 (1862). 



Habitat in lauretis excelsioribus Teneriffse, hinc inde baud infro- 

 quens. 



This curious species, so remarkable for its thick squarish body and 

 flattened surface, and for the apical ridges of its elytra being length- 

 ened out into a hinder process, or a kind of obtuse tail, is extremely 

 local, but not very uncommon in the laurel-woods towards the north- 

 eastern extremity of Teneriffe. In the highest (sylvan) part of the 

 Las Mercedes' range, as also in the dense forest above Taganana, I 

 took it, in tolerable abimdance, during May 1859.
