 and dehcate ones. 



Its habits appear to be the same as those of the Madeiran and 

 Canarian C. WoUastonil, as I am informed by Mr. Bewicke that he 

 captured it "■ in an ants' nest on the Atlantic side of the promontoiy 

 of the Cape, about three or four hundred feet above the sea." It 

 would seem to be very scarce, for Mr. Bewicke states that he 

 "searched diligently, but without effect, for more;" — adding, 

 " From the locality in which I took it, miles from even a road, 

 amidst thick underwood and rocks, I should consider it as certainly 

 a tnie native of the Cape.'*

The two insects* on which the present genus is foimded arc so 

 very close, in general aspect and structure, to the Madeiran and 

 Canarian Europs, that it was not until I had examined them mi- 

 nutely that I could conceive it possible that they should perhaps be 

 regarded as distinct ; whilst even now I am anything but satisfied 

 that they ought not rather to be treated as aberrant members of 



* Whether the Ehyzophagim capensis and rufidus of Dejean's Catalogue, 

 registered as natives of the Cape, be these two insects (which is not impossible, 

 from their great external resemblance to Ehyzophagi), I cannot tell ; as, however, 

 they are niei*e Catalogue-species, it fortunately is not of much imj)ortance to 

 ascertain.
