576 INSECTA MADERENSIA. 



the deep and moist ravines. In sueli positions I have captured it, during the 

 winter and eaidy spring months, towards the head of the Eibeii'O de Santa Luzia ; 

 as also at the Ribeiro Frio, in August. 



447. Othius Jansoni, iT'oU. 



O, niger nitidus, capite prothoraceque politissimis, elytris plus minusve rufo-picescentibus, antennis 



pedibusque pallido-ferrugineis. 

 Long, coi-p. lin. 4-4|. 



Habitat in locis similibus ac praecedens, byeme nisi fallor pi-fcdominans. 



Uom". E. W. Jansono, Soc. Ent. Londinensis curatori necnon Staphylinorum investigatori felicissimo, 

 hunc Othium certe novum tribui. 



O. smaller and rather narrower than the O. strigulosus, black, and shining. Head and prothorax very 

 highly polished, and without any appearance (except under a high microscopic power) of the 

 minute punctures and the transversely-strigulose sculpture which are so evident in that species ; 

 but with about the same arrangement of larger impressions towards their sides (those, however, on 

 the head being perhaps rather less numerous). Elytra as in that insect, but more coarsely punc- 

 tured, and with no appearance of under-granules ; also usually somewhat more rufescent, — 

 especially at the lateral edges (which are more evidently pilose) and apex. Abdomen a little 

 constricted at the base ; and with its apex, and occasionally the lateral margins, slightly diluted 

 in colouring. Anteiin<e and legs pale ferruginous ; with the tibia more or less infuscated. 



Found, usually, under the same circumstances as the last species, and possessing 

 about an equal range. I have captured it more abundantly in the Eibeu-o de 

 Santa Luzia than elsewhere, and i^rincipally diu-ing the Avinter months. It has 

 been also communicated to me by M. Rousset from the Pico d'Arribentao, above 

 Funchal. I have dedicated the species to E. W. Janson, Esq., Cm-ator to the 

 Entomological Society of London, whose well-known attention to Brachelytrous 

 insects has aided so much in the elucidation of British forms.

 truncato, antice sulculis quatuor abbreviatis imprcsso ; nculis rotundatis parvis : prothorace ut in 

 Othio, sed punctorum seriubus quatuor plerumque notato, et basin versus subangustiorc : elytris

 Pedes breves robusti ; coxis intcrmcdiis distantibus ; pnstici anterioribus debiliorcs : tibiis spinu- 

 losis : tarsis 5-articulatis simplicibus ; intermediis paulo longioribus ; omnibus articulis primo et
