156 Mr. T. Vernon Wollaston on the Eiiphorhia-infesting 



Habitat ins. Gomer.Te, Februario ineunte a,d. 185S in ramis 

 Euphorbias canariensis putridis sat copiose captus. 



As may be gathered from the foregoing remarks, the T. Ty- 

 phceoides may be distinguished from the last species by its rather 

 smaller size and narrower and more parallel outline, as well as 

 by its less convex surface, coarser and longer pubescence, by its 

 shorter prothorax (which is equally rounded at the sides), deeper 

 sculpture, and by the less thickened margin of its elytra. I have 

 observed it hitherto only in the island of Gomera, where, early in 

 February, 1858, I took it in considerable profusion from out of 

 the rotten branches of the Euphorbia canariensis on the hills im- 

 mediately to the north of San Sebastian, — in which locality it was 

 subsequently captured by Mr. Gray. 



Fam. CRYPTOPHAGID^. 



Genus Cryptophagus. 

 Herbst, Kaf. iv. 172 (1792). 

 11. Cryptophagus fusiformis, n. sp. 

 C. oblongo- fusiformis, angustulus, fusco-ferrugineus, pube 

 minus elongata subdepressa vestitus ; prothorace profunda 

 et dense punctato, ad latera subrecto, denticulo medio acuto ; 

 elytris subfusiformibus (i. e. antice et postice subattenuatis, 

 vel ibidem utrinque oblique subtruncatis), sat dense punc- 

 tatis ; alis obsoletis. 

 Long. corp. lin. vix f . 



Habitat Teneriffam, praecipue sub cortice Euphorbiarum in 

 montibus supra Sanctam Crucem crescentium deprehensus. 



The small size and rather narrow and fusiform outline of this 

 Cryptophagus, in conjunction with its short and depressed pube- 

 scence, the somewhat straightened sides of its prothorax, and 

 (which is very unusual in the present genus) its obsolete wings, 

 will sufficiently distinguish it. In its habits it is more strictly in- 

 digenous than most of the Canarian Cryptophagi, occurring in 

 spots far removed from habitations,^ — such as at Las Mercedes, 

 and from beneath the bark of dead Euphorbias on the mountains 

 above Santa Cruz, of Teneriflfe (which is the only island in which 

 I have hitherto observed it).
