278 INSECTA MADERENSIA. 



A. velatiim and striatum ; but the above characters will, of themselves, suffice to 

 distinguish it. In its habits it is less strictly lignivorous than any of the re- 

 mainder ; being evidently an imported insect into Madeira, where it is found about 

 houses and amongst stores, especially biscuit and bread, — on which, as well as on 

 different kinds of merchandise, it appears to subsist. It is occasionally tolerably 

 common around Funchal ; and I once captured it in abundance in the city itself, 

 — on the walls of the house belonging to my friend Dr. Ross, in the Rua da 

 Carreii'a, — at the beginning of January 1848. 



212. Anobium striatum. 



A. subcylindricum brunneum et subtilissime pubescens, prothoracc infecniali (postice carinato-nodoso) 

 et granulis minutissimis punctisque obscuris obsito, antice acuniinato-prodiicto necnon ad 

 angulos posticos sinuato, elytris punctato-striatis, antennis pedibusque feiTugineis.

A. subcylindrical (being proportionably rather narrower, especially anteriorly, than either of the pre- 

 vious species), of a more or less obscure broflu, and densely clothed with most minute and 

 decumbent pile. Prothorax closely beset with veiy small and obscure granules and punctm-es ; 

 rather elongated and narrow, — particularly iu front, where it is both constricted and rounded 

 (which gives the sides an unequal, or undulating, appearance) ; with the hinder angles sinuated, 

 or scooped out; with a slightly impressed longitudinal channel, and a greatly elevated keel- 

 shaped nodide in the centre of the hinder disk, — on either side of which the surface is trans- 

 versely impressed. Elytra a little paler than the prothorax, punctate- striated; and with the in- 

 terstices rather convex, though scarcely punctulated. Antenna and legs more or less ferruginous. 



A most abundant Eui'opoan jlnohunn ; and one which has in all probability, 

 like the last species, been naturalized in Madeira from more northern latitudes. 

 It is an insect in fact peculiarly liable to dissemination over the world through 

 the agency of commerce, — being attached to rotten wood, and often making its 

 appearance in considerable numbers on board shi}). It is widely distributed OA'cr 

 IVIadeira, though it does not seem to occur anAn\'here in profusion. I have cap- 

 tured it in the vicinity of Funchal during the early spring, at Canical in ^lay, at 

 Santa Anna and Sao Yincente in Jime, and at the Ribeiro Frio and the Feijaa de 

 C6rte in August.
