The present Ceuthorhi/nchas and the he^perus are remarkable, inter 

 alia, for their third elytral interstice (and indeed the alternate ones 

 also on the outer side of it, though less evidently so) being not only 

 widened and somewhat raised, but also sparingly tessellated with 

 blackish and whitish scales. Their femora, moreover, are armed be- 

 neath with an acute spine. In its special characters, the C. ])hyto- 

 bioides is rather smaller than its ally ; its elytra (which are rounder 

 and more obovate) are not quite so black and have their striae less 

 evidently punctured ; and its limbs are longer and rather paler — the 

 first two joints of the funiculus and the basal one of the feet being 

 conspicuously more elongated. As in many of the CeutJiorhi/nchi, its 

 male sex (which I have alone seen) has the inner apices of its four 

 hinder tibiae produced into a very minute terminal spine. It is 

 hitherto unique, the single example from which the above diagnosis 

 has been di'awn out having been captured by myself, during May 

 1859, at Taganana, in the north of Teneriflfe. Its rounded elytra 

 and elongate legs, in conjunction with its tubercled prothorax, give 

 it much the appearance, prima facie, of a Phytobius — a fact which 

 has suggested its specific name*.

* In affinity the C.fhytohioidcs is evidently very close to the Madeiran lineafo- 

 tesseUahis, agreeing with that insect almost exactly in its outline and sculpture 

 and in the general plan of its ornamentation ; nevertheless specifically it is abun- 

 dantly distinct from it, being scarcely more than half the size and of a different 

 colom-, with the basal joint of its feet relatively more elongated and with the 

 tooth of its front tibiae much more developed.
