861. Ocypus affinis, n. sj). 



0. praecedenti affinis sed (nisi fallor) vere distinctus ; paulo minor, 

 angustior, pnnctura omnino fortiore ac (prajscrtim in abdomine) 

 parciore ; capite subminore, sensim convexiore ; prothoracis linea 

 media obscuriore ; elytris paulo minus abbreviatis ; antennis pedi- 

 busque clarioribus, illarura articulis apicalibus subbrevioribus. — 

 Long. eorp. lin. 9-12. 



Habitat Teneriffam (Dom. Hartung) et Palmara, in loeis similibus 

 ac prsecedens. 



Although closely allied to the hrachripterus, I do not think it possi- 

 ble that this Oci/jms can be any modification of that species. So far 

 as I have myself observed, it is confined to the sylvan districts of 

 Palma, as the hrachyptenis is to those of TenerilFe ; nevertheless, of 

 two examples which were communicated by Dr. Heer as Tener\ffan, 

 and which were taken by M. Hartung, one pertains to the hracliy- 

 pteriis and the other to the affinis. As it is certain, however, that 

 many of M. Hartung's specimens from the various islands became 

 afterwards accidentally mixed up, its Teneriffan habitat requires fur- 

 ther corroboration. It is altogether a little smaller and narrower 

 than the hrachyptenis, and its punctation is both stronger and (par- 

 ticularly on the abdomen) less dense ; its head is a trifle less developed 

 and more convex, its central prothoracic line is less conspicuous, its 

 elytra are not quite so abbreviated, and its limbs are of a clearer hue, 

 with the apical and subapical joints of the antennae perhaps a little 

 shorter. My specimens (from the intermediate districts of Pahna) 

 were captured high up in the Barranco de Galga and in the Barranco 

 above S''* Cruz. 



862. Ocypus umbricola, n. sp. 



0. colore et sculptura 0. brachypfero fere similis, sed multo minor 

 angustior ; capite prothoraccque obsoletissime submetallico-tinctis, 

 illo minore subovali (nee rotundato); elytris paulo minus abbre- 

 viatis necnon ad angulos cxternos posticos minus oblique truncatis ; 

 antennis pedibusque parcius fulvo -pilosis. — Long. corp. lin. 6-8. 



Habitat in humidis sylvaticis Teneriffae, rarissimus. 



In its dense and fine pimctation and general hue, this Ocypus is 

 nearly similar to the hrachypterus ; but it is very much smaller and 

 narrower, and its head and prothorax have often a slight metallic 

 tinge ; its head is also relatively smaller and less rounded, its elj-tra 

 are not quite so shortened, nor so much truncated obliquely at their 

 hinder external angles, and its limbs are more sparingly jnlose. I 

 have detected it hitherto only in the damp sylvan regions of Teneriffe, 

 where, moreover, it is extremely scarce. I have taken it sparingly
