Two specimens (a male and female) of this insignificant little Tij- 

 chius were captured by myself, from beneath stones, in a flat sandy 

 spot at the edges of the coast-road, in Fuerteventura, about three 

 miles to the north of Puerto de Cabras, on the 9th of April 1859. 

 They are about the size of the common European T. Jlavicollis, but 

 are somewliat narrower and more parallel, with their scales a little 

 browner and more metallic, and with their rostrum and antennae (in 

 both sexes) shorter. The last indeed are rather singular from the 

 second joint of the funiculus being not at aU longer than the third, 

 whilst the basal one is (relatively) a trifle more swollen perhaps than 

 is the case in the ordinary I'ycliii. In minor particidars, I may just 

 mention that, wlien denuded of its scales, the forehead of the T. de- 

 pauperatus will be seen to be much more opake and densely punc- 

 tured than in theJlKvlcolIis, and its elytra! stria? to be less distinctly 

 crenulated.

The three Auletes here enumerated are very closely allied inter se, 

 and I do not feel altogether satisfied that they should be regarded as 

 more than varieties of a single very plastic species. Nevertheless I 

 think it is more probable that they are distinct, though nearly re- 

 lated, and therefore I consider it safer not to amalgamate them. 



The A. Cj/Jimh-icol1is appears to be widely distributed, tliough spa-
