CANARTAN COLEOPTERA. 99 



Apparently of the greatest rarity. I captured four specimens of 

 it in the sylvan district of El Golfo, on the western side of Hierro, 

 during February 1859 ; and another (which although of a pallid hue 

 I believe to be conspecific with the rest, and merely immature) in 

 the region of El Monte, in Grand Canary, later in the spring of the 

 same year. 



161. Anisotoma oceanica, n. sp. 



A. breviter ovalis postiee subacuta, valde convexa, nitidissima, nigro- 

 picea; capite prothoraceque levitcr punctulatis, illo rufescente ; ely- 

 tris apice acutiuscidis et ibidem paulo pallidioribus, versus basin 

 obsolete rufescentioribus, levissime punctato-striatis, interstitiis 

 minute punctulatis ; antennis ad basin pedibusque rufo-ferrugineis.

Habitat in montibus sylvaticis TenerijGFa3, sub foliis dejectis ad Las 

 Mercedes capta. 



Like the last species, the present one would appear to be exces- 

 sively scarce, — being, in fact, hitherto unique. It was taken by my- 

 self, during June 1858, from beneath dead leaves, under the old trees 

 in the highest part of the forest of Las Mercedes, in Teneriffe. It 

 may be kno'wn from the A. eanariensis by being more shortly ovate, 

 and posteriorly subacute, by its convexer, more minutely punctulated 

 and more highly polished surface, by its finer and more delicately 

 punctured striaj, and by the apex of its elytra being gradually some- 

 what more j)ellucid, — causing that portion to apj)ear slightly paler 

 than the rest of the surface.

A. nigrum, prothoracis limbo obsciire rufescentiore ; capite protho-

 circa medium) sat distincte sed minute punctulatis, ad humeros

 antennis pedibusque piceo-ferrugineis.

The present Agathidimn is about the size of, or perhaps a little 

 larger than, the European A. mandibulare. It is, however, remark- 

 able for its evidently, though minutely, punctulated surface (the
