INSECTA MADERENSIA. 279 



minutis creberrimis obsito, antice vix producto, elytris paulo dilutioribus leviter punctato- 

 striatis, anteuuis pedibusque ferrugiueis.

 Dom. Leacock. 



A. cylindrical, brown with more or less of a rufescent tinge, and densely clothed with short pile, — 

 which is dark and erect upon the prothorax, but pale and almost decumbent on the elytra. 

 Prothorax very closely beset with minute points or granules, — which, in conjunction with the 

 short pile, give the surface an almost velvety appearance ; convex, slightly produced m front, 

 and with the sides rounded ; perfectly even, having no appearance of elevations, nodules, or even 

 of a central line. Elytra a little paler than the prothorax, — the colour and decumbency of the 

 pubescence however causing it to seem paler than it really is j rather lightly punctate- stiiated ; 

 and with the interstices wide (but not quite flattened), though scarcely punctulated. Antenna 

 and legs ferruginous. 



Readily known by its large size and extremely cylindrical form (in wliich 

 respect it bears a very strong prima facie resemblance to a Ptilinus), and by the 

 small thickly-set granules and somewhat velvety surface of its (comparatively 

 globose) prothorax, — the pubescence of wliich is darker and more erect than that 

 of the elytra. It is one of the insects which entii'ely escaped my own observations 

 in these islands, — the only tlu-ee specimens which I have seen having been recently 

 communicated to me by T. S. Leacock, Esq., by whom they were captured near 

 Fimchal.
