CANARIAN COLEOPTETt.V. 317 



A single specimen of this insect, captured (dead) from beneath a 

 stone, in the wood of the Agua Garcia of TenerifFe, during March 

 1858, seems to agree preciselywith the unique example of my " Tij- 

 chius alhosqnamosiis " which I found (likewise dead, and under a 

 stone), in May 1850, on the Dcserta Grande of the Madeiran Group. 

 At least, after a very accurate comparison, I cannot detect a real 

 difference between the two ; and I have therefore regarded them as 

 identical. The S. alho^quamosns recedes from the paupcrcuivs in 

 being a little larger and more parallel ; in the colour, both of its 

 body and limbs, being (when denuded of the scales) completely black ; 

 in its prothorax being a trifle more sparingly and less roughly punc- 

 tured ; and in its scales being not only very much larger, wider, and 

 more robust, but likewise of a more chalky white (though apparentlj^ 

 with brownish ones intermixed). 



The examples, four in number, which in the above diagnosis I 

 have treated as the " var. fl " may possibly prove to be specifically 

 distinct from their supposed type. Two of them were taken by Mr. 

 Gray near Orotava in Teneriffe, another was captured by myself in 

 the same locality, and the remaining one I met with (on tlie 11th of 

 February 1858) on the ascent from Port Hierro to Yalverde, in the 

 island of Hierro. They differ in being very much less densely squa- 

 mose (the paler scales, more particularly, being few in number), and 

 in their prothorax being a little more sparingly and finely punctured. 

 Still, in the absence of further material (both of them and of their 

 supposed type) to judge from, I think it would scarcely be safe to 

 consider them as more than a variety of the albosquamosus.

This insect, which seems to be one of the most minute of the Cana- 

 rian CurcuUonidce, will probably be found to be universal, tlu'oughout 

 at all events the central and western islands of the archipelago. 

 Hitherto, however, I have observed it only in Grand Canary and 

 Teneriffe, — namely in the region of El Monte and at Teror of the 

 former, and about S'* Cruz and Orotava of the latter. It is appa- 

 rently, on the average, a little smaller than the S. albosquamosus, its
