moreover, being dark info-ferruginous throughout (for the interme-

Genus TARUS. 

 ClairviUe, Ent. Helv. ii. 94 (1806). 



Tarus velatus, n. sp. 



T. subnitidus, nigro- vel fusco-piceus sed in limbo plus minus evi- 

 denter dilutior, pilis mollibus erectis fulvis vestitus, ubique dense 

 (in elytris vix levius) punctatus ; prothorace latiusculo, angulis 

 ipsis postieis vix subrecurvo-exstantibus ; elytris ovalibus, sub- 

 convexis, sat profunde subcrenato-striatis ; antennis, palpis pedi- 

 busque (sensim pallidioribus) testaceis. Long. corp. lin. 4-15. 



Habitat Gomeram, in montibus humidis sylvaticis a DD. Crotch 

 deprehensus. 



Several specimens of this fine Tarus (so remarkable for its deeply 

 and densely punctured surface, which is beset with a fine, soft, erect, 

 though not particularly elongate, fulvous pile) were taken by the 

 Messrs. Crotch at a high elevation in the laurel-forests (above Her- 

 migua) of Gomera, during the summer of 1864. In colour, clothing, 

 and sculpture it is almost identical with the T. amictus, of which I 

 add below an amended diagnosis ; nevertheless it is very much larger, 

 and has (inter alia) its head and prothorax relatively wider and 

 more transverse. 



Tarns amictus. 



T. preecedenti similis, sed minor, vix levius punctatus ; capite pro- 

 thoraceque angnstioribus, hoc magis cordato, angulis ipsis postieis 

 paulo evidentius subrecurvo-exstantibus ; elytris vix magis depres- 

 sis, striis fere simplicibus. Long. corp. lin. 3* 3| (var. /3. 3-3|). 



Var. /3. simillima [an species ?]. Paulo minor, subnitidior et vix 

 profundius punctata; elytrorum striis subprofundius impressis; 

 antennis vix brevioribus, clarioribus. 



Tarus amictus, Woll, Cat. Can. Col 21 (1864). 



Habitat sylvatica excelsa Canariae et Gomerae, in ilia a meipso sed in 

 hac a DD. Crotch repertus. 



This Tarus seems to differ from the preceding one simply in being 

 considerably smaller, with its head and prothorax (the latter of which 

 has the posterior angles rather more evidently prominent, or upwardly 

 subrecurved) relatively narrower, and with its elytra just perceptibly 

 less convex. The specimens however from which the above diagnosis 

 has been compiled present two slightly different forms even amongst 

 themselves, one of which (regarded as normal) is a trifle larger, as
