CANARIAN COLEOPTERA. 385 



of the sub-Ehynchophoroiis Xylophagous groups (such as Hylastes, 

 &c.) at the opposite extremity of the Curcidionidce. Yet its entire 

 external conformation, particularly of the antennae, removes it com- 

 pletely from all such forms ; whilst its 4-jointed (or " pseuclotrime- 

 rous ") feet (the third articulation being- excessively minute) render 

 its relationship still more dubious. Upon the whole, it seems to me 

 to combine the two ojyjiosite extremes of the Rliyncliopliora (as repre- 

 sented by the Hylesinidce and Antlirihidce) with certain setose genera 

 of the Colydiadoi (such as Sarrotrium and Diodesma) in which the 

 body is hispid and the tarsi quadriarticulate. Nevertheless, not 

 venturing to assign it positively to the Antlirihidce, I have been com- 

 pelled to place it in a separate Family. 



586. Aglycyderes setifer. 

 A. niger vel piceo-niger, opaeus, valde asperato-rugosus setisque ro- 

 bustis squamiformibus fuseo-albidis (in capite prothoraceque sub- 

 demissis, sed in eljtris erectis) obsitus ; prothorace subquadrato, ad 

 latera rotundato, profunde canaliculato ; elytris dense et rugose 

 punctato-striatis, interstitiis subelevatis ; antennis (gracilibus) 

 pedibusque (robustis) paulo picescentioribus, squamosis. — Long, 

 corp. lin. 1-1 3. 



Aglycyderes setifer, Westtv., loc. cit. (1863). 

 Habitat in infcrioribus intermcdiisque Lanzarotse, Fuerteventuree, 

 Canarise, Teneriffse et Palmae, vel in caulibus Euphorbiari'm putridis 

 vel sub cortice Ficorum arido laxo, hinc inde congregans. 



This curious little insect, so remarkable (even prima facie) for its 

 dark, brownish-black, opake, setose surface, thick, abbreviated legs, 

 slender antennae, and for its (flattened) head being in the female sex 

 triangular, whilst in the male it is dilated in front of either eye into 

 a lateral lobe, or horn, wiU almost certainly be found universally 

 throughout the Group, though hitherto it does not happen to have 

 been observed in either Gomera or Hierro ; but in Lanzarote, Fuerte- 

 ventura (or rather on the little island of Lobos, off the extreme north 

 of it). Grand Canary, Teneriffe, and Palma I have taken it (more or 

 less abundantly). I first detected it congregating beneath the dry 

 loosened bark of a fig-tree in the waste ground above the Puerto 

 Orotava of Teneriffe ; and I subsequently met with it under similar 

 circumstances in the Banda of Palma. Nevertheless even in those 

 instances it was in the immediate vicinity of Euphorbias ; and since 

 I have also actually captured it (on the mountains of Teneriffe, above 

 Laguna, as well as in Lobos, and elsewhere) within the rotten stalks 

 of the Euphorbia canariensis, I suspect that it is, at any rate in its 

 earlier stages, of ^M^:)7io»-5/rt -infesting habits.
