which have their extreme outer margin dark, as well a large suffus 

 patch on the hinder disk of each) are brownish-testaceous. Its abd 

 men also has the posterior half of each segment conspicuously diluted 

 in hue. But, apart from colour and outline, it may immediately be 

 known from that species by its antennae being more abbreviated and 

 compact, with the terminal articulation shorter and more globose, 

 and by its three elytral lines being very much more closely punctured, 

 with the punctures smaller and more asperate. 



The M. discoideus is far more closely allied however to the solidi- 

 cornis, with which indeed I am inclined to think that it may prove 

 eventually to be conspecific ; though, with but a single example of 

 each for comparison, I scarcely like to amalgamate them. Judging 

 from the type now before me, it seems to differ from the latter chiefly 

 in its larger size, in the last joint of its antennae being a little broader, 

 and in the infuscated portion of its elytra being both more expressed 

 and more concentrated into a large patch on the disk of each. If it 

 should be shown ultimately to be but a state of the solidicornis, of 

 course the latter name (as being the prior one) will have to stand 

 for the species. 



Genus OCYPUS. 

 (Kirby) Steph., Ill Brit. Ent. v. 211 (1832). 



Ocypus sylvaticus, n. sp. 



0. niger vel piceo-niger (ssepius in elytris paulo rufescentior), sub- 

 nitidus elytris subopacis ; capite prothoraceque plus minus obsolete 

 seneo-tinctis, sat profunde punctatis, parce pubescentibus, illo 

 parum magno subrotundato convexo, hoc subcarinato-lineato ; 

 elytris brevibus, densius pubescentibus ac densius asperato-punc- 

 tatis; abdomine parce asperato-punctato ; antennis pedibusque 

 piceo-ferrugineis et (praesertim his) fulvo -pubescentibus. Long, 

 corp. lin. 7J-11. 



Habitat in sylvaticis Gomerae editioribus, a DD. Crotch repertus. 



Twenty examples of this Ocypus, from which the above diagnosis 

 has been compiled, were taken by the Messrs. Crotch in the laurel- 

 woods above Hermigua in Gomera. The species much resembles the 

 curtipennis from Grand Canary, but its head and prothorax are less 

 shining, less brassy, rather less pubescent, and not quite so thickly 

 punctured ; its elytra (although short) are a little less abbreviated, 

 much less closely and somewhat more coarsely beset with asperated 

 punctules ; and the punctules of its abdomen are very much more 

 remote. The last-mentioned character, indeed, will separate it from
