88 Mr. T. V. Wollaston on the Coleoptera of the Salvages. 



I can alone vouch) most closely and delicately alutaceous all over — [a 

 structure which is very conspicuous under a high magnifying power, 

 but which is only just traceable on the prothorax] ; lightly and regu- 

 larly subcrenate-striate, the strire being fine and narrow ; with two 

 punctures, just within the third stria, down the disk of each, and with 

 the interstices rather flattened. Limbs rufo-piceous ; the antenna; 

 brighter at their base. 



The present Pterostichus, two female specimens of which have 

 been communicated to me by the Barao do Castello de Paiva, is 

 closely allied to the P. canariensis of Brulle, which I have taken 

 abundantly in Lanzarote, Fuerteventura, and Grand Canary ; never- 

 theless it is rather smaller and less brilliant than that insect, — the 

 entire surface of its elytra (at least in the females, of which I can 

 alone speak) being densely and distinctly alutaceous (a sculpture 

 which is just traceable even on the prothorax also) ; its prothorax is 

 a little less expanded anteriorly, and with its dorsal charrnel more 

 abruptly terminated both before and behind ; and its elytral striae 

 are finer, narrower, and shallower, with the interstices much less 

 convex.

3. Harpalus pelagicus, n. sp. 



H. oblongus, latus, subnitidus, niger vel nigro-piceus ; prothorace trans- 

 verso, convexo, ad latera subaequaliter rotundato (basi haud constricto, 

 sed paulo angustiore), utrinque leviter foveolato, angulis posticis ob- 

 tusis; elytris leviter crenato-striatis (stria subsuturali abbreviate lon- 

 giuscula) ; antennis rufo-ferrugineis, pedibus rufo-piceis. 



Long. corp. lin. 4}-5. 



H. oblong, broad, shining (but not very brilliantly so), and black (or, 

 when immature, piceous-black). Head rather large. Prothorax broad, 

 transverse, and convex, almost equally rounded at the sides (i. e., with 

 the edges in a continuous curve, — not being suddenly attenuated, or 

 constricted, posteriorly, though a little narrower behind than before ) ; 

 almost unpunctured, though with a shallow and obscurely punctured 

 fovea on either side, at the base, behind. Elytra lightly striated, the 

 stria? being finely but distinctly crenulated ; with the abbreviated 

 second stria longer than in the Madeiran and Canarian Harpali of this 

 type, and completely joining the sutural one at a great distance behind 

 the scutellum ; more truncated at their base than in the other Harpali 

 of this type, the humeral angles being less porrected and more obtuse ; 

 a little acuminated at their apex, but not minutely divaricate as in the 

 H. vividus. Antenna rufo-ferruginous. Leas rufo-piceous. 



The Harpalus here described is one of a small cluster of Atlantic
