 Tarphius deformis, Woll, loc. cit. 387. pi. 19. f. 9 (1862). 

 Habitat TenerifFam sylvaticam, late sed parce diflfiisiis. 

 Widely spread over the sylvan regions of TenerifFe, though appa- 

 rently everywhere scarce. I have taken it, very sparingly, at the 

 Agua Mansa, the Agua Garcia, and by the edges of the Vneltas on 

 the wooded mountains above Taganaua.

Habitat in formicarum nidis TenerilFse et Gomerte, rarissimus. 



This very remarkable and interesting little insect, which occurs in 

 ants'-nests in Madeira, is found also, in similar positions, at the Ca- 

 naries. So far as I have observed hitherto, however, it appears to 

 be exceedingly rare, — the only spots in which I have taken it being 

 immediately outside the Puerto Orotava of TeneriiFe and in the Bar- 

 ranco above San Sebastian of Gomera. 



Genus 88. AULONIUM. 

 Erichson, Nat. der Ins. Dmtsch. iii. 275 (1848). 



216. Aulonium sulcicolle, n. sp. 



A. elongatum, cylindricum, nitidum, piceo-nigrum, elytris, antennis 

 pedibusque rufo-ferrugineis ; capite prothoraceque minute punctu- 

 latis, illo antice picescentiore, postice bituberculato, hoc 4-sulcato, 

 sulcis intermediis antice evanescentibus, postice divergentibus ; 

 elytris minutissime (sed vix subseriatim) punctulatis. — Long. corp. 

 lin. 2-2^. 



Habitat TenerifFam et Palmam rarissimum, sub cortice Pini cana- 

 riensis emortuo erodens. 



The present Auloniimi seems, in some respects, to be intermediate 

 between the European A. sulcatum and bicolor ; though in its general 

 colour and bitubercnlated head, as well as in the excessively fine 

 punctules of its elytra, and the elevated, or costate, edge of the an- 

 terior portion of its outer prothoracic sulci, it has certainly more in 

 common with the latter than with the former. It is, however, larger, 

 and relatively broader, than the A. bicolor ; its elytra are entirely 

 rufo-ferruginous (instead of with the posterior portion black), and
