INSECTA MADERENSIA. 187 



spiniform and somewhat acute lobe, — likewise surmouutcd at the extremity (as in all the other 

 joints of the tarsi throughout the genus) with a small tuft of pile. 

 Female, as yet undiscovered. 



Hitlierto unique ; nevertheless the remarkable structure of its feet, — the speci- 

 men happening fortunately to be a male, — will prevent the possibility of its being 

 confounded vrith any of the other species hitherto discovered. It may be at once 

 knovpn, so. far as that sex is concerned, by its intermediate tarsi being almost 

 sinij)le, vt^hilst the anterior and j)Osterior ones are produced beneath into a long 

 and robust spiniform lobe. I am not quite certain as to the exact position in 

 which it was taken ; l3ut I believe that I captured it either at the Ribeu'o Frio or 

 at the Lombo dos Pecegueu-os, during the summer of 1850. 



110. Tarphius sylvicola, Wall. 



T. rotundato-ovatus brevis subnitidus niger, prothorace antice attenuato, granulis crebris magnis 

 obtusissimis obsito, elytris concoloribus profunde seriato-punctatis, pone medium leviter nodosis, 

 tarsis in utroque sexu simplicibus. 



Long. Corp. lin. li-lj. 



Habitat in Maderse sylvaticis, ad Ribeiro Frio necnou ad Lombo dos Pecegueiros sestate media 

 A.D. 1850 deprehensus. 



T. short and round, of a deeper black than any of the other species, almost free from scales, and a 

 little shining. Head and prutliorax beset with very close, large and exceedingly obtuse granules : 

 the latter not channeled, short, much dilated behind and narrowed in front (the sides, although 

 oblique, being comparatively but very slightly curved). Elytra concolorous, short and much 

 rounded behind, deeply seriate-punctate, and without transverse wrinkles, — the punctures being 

 large, regular and distinct ; with three or four rather obscure nodules between the apex and the 

 centre of the disk. Antenrue and tarsi (which are simple in both sexes) pale fen-uginous : the 

 femora and tibiee darker, though paler and more piceous than the rest of the surface. 



A well-marked little species ; and one which may be known by its short rounded 

 form and dark concolorous hue, — the elytra moreover being armed with small 

 protuberances towards their hinder region. It is more allied to the T. rotmidahis 

 than to any of the other Tarphii here described ; nevertheless its smaller size and 

 anteriorly-attenuated prothorax will, apart from the nodules of its unspotted 

 surface, readUy separate it from that insect. It is one of the rarest of the genus, 

 four specimens being all that I have hitherto captured of it, — two of which were 

 taken at the Ribeu'o Frio, and two at the Lombo dos Pecegueu'os, diu'ing July 

 1850.
