508 CANARIAN COLEOPTERA. 



vation on the mountains of Grand Canary — namely in the Pinal above 

 San Bartolome, in the central region of Tarajana ; where, dm-ing 

 April 1858, I captured it not uncommonly, from beneath stones, 

 under the fir-trees. 



759. Helops rimosus, n. sp. 



H. angustulus, niger, parum nitidus ; capite prothoraceque dense 

 punctatis, hoc ad latera subsequaliter rotundato, ante angulos pos- 

 ticos argute obtusos vix sinuato ; elytris cylindrico-ovalibus antice 

 angustatis, profunde crenulato-striatis, interstitiis grosse trans- 

 versim rimosis sed quasi impunctatis (/. e. punctuhs subtilissimis, 

 nisi oculo fortissime armato baud discernendis) ; antenuis pedi- 

 busque piceis, tarsis dilutioribus. — Long. corp. lin. 4|. 



Ohs. — H. congeneri ali(|uo modo similis, sed angustior, el}i;ris 

 magis cylindrieis, tamen antice angustioribus, in interstitiis multo 

 magis transversim rugosis (so. valde ac profunde rimosis) necnon 

 multo subtilius punctulatis (punctulis aegerrime observandis), pro- 

 thorace ad latera magis a^qualiter rotundato, genis vix minus ex- 

 stantibus, tibiis sensim gracilioribus antennarumque articulo 3"° 

 minus elongato. 



Habitat Puerteventuram, a Dom. Gray Januario exeunte a.d. 1858 

 scmel tantum repertus. 



A single example of this distinct Helops was taken by Mr. Gray 

 in Fuerteventura, at the end of January 1858. Although with some- 

 what the prhnd facie aspect of the //. conge^ier, it may easily be 

 known by its narrowish outline and convex, though anteriorly-con- 

 tracted elytra, the interstices of wliich are very coarsely wrinkled 

 (or, rather, craclced, or rimose) transversely, but with their punc- 

 tules so excessively diminutive that they are quite invisible except 

 beneath a high magnifying power. Its prothorax is a good deal 

 (and subequally) rounded at the sides; its tibige are rather slender, 

 and its third antenna! joint is less elongated than is usual in the 



allied species. 



760. Helops porrectus, n. sp. 



//. aterrimus, nitidus ; capite prothoraceque densissime sed vix pro- 

 funde punctatis, hoc transverso-quadrato, ad latera minus rotun- 

 dato, angulis anticis acutis porrectis (ergo ad apicem quasi pro- 

 funde bisinuato), posticis subrectis (rarius obtusiusculis), per basin 

 subarcuato-truncato ; elytris profunde striato-punctatis, interstitiis 

 minute punctulatis. — Long. corp. Un. 5-6. 



Habitat Lanzarotam borealem, rarior. 



The large size and shining, intensely black surface of this species, 

 combined with its subquadrate and thickly (though not very coarsely) 

 punctured prothorax, which has its front angles rather acute and
