132 H. C. FALL. 



Antenna? 11-jointed, presternum long before the coxa?, mesosternum 



oblique Ozognatlius. 



Prothorax not margined at sides X ;t I'il'a. 



Front coxse conical, very prominent and contiguous. 



Fourth tarsal joint short, emarginate; antenual stem not serrate; protborax, 

 except very rarely, with sharply defined side margin.. .Ernobius. 

 Fourth tarsal joint elongate, not emarginate; antenual stem serrate; pro- 

 thorax not margined at sides Paralobium. 



Of the above genera only Ernobius and Xestobium occur in 

 Europe, where, owing to a different basis for classification they are 

 included in the Anobiini. The genera Episernus Thom. and 

 china Steph. represented in Europe by a moderate number of spe- 

 cies would also fall in the Dryophilini as above constituted ; in fact 

 the former genus is doubtfully distinct from Ernobius, being distin- 

 guished only by the 10-jointed autennse and non margined sides of 

 the prothorax, characters which are possessed wholly or in part by 

 two of our species which I have not thought best to separate geuer- 

 ically from Ernobius. Ochina is quite anomalous in its feebly ser- 

 rate antenna? with the outer joints not elongate, and therefore placed 

 by European systematists in the Xyletiniui. It is one of those 

 genera with composite affinities and for this reason not easy to place 

 in line. The front coxse are contiguous and the tarsi rather slender, 

 with the fourth joint emarginate. I should therefore place it after 

 Ernobius. 



Two genera only constitute the Dryophilini in the European 

 Catalogue, viz. Dryophilus and Priobium, both of which are unrep- 

 resented in America. They differ from all our genera in their regu- 

 larly punctate-striate elytra. Priobium, because of its distant front 

 and middle coxa? should stand at the head of the tribe, where also 

 one would naturally place it because of its resemblance to the pre- 

 ceding tribe in its relatively narrow unmargined prothorax. In 

 Dryophilus the thorax is also without side margin, and this together 

 with the more frontal insertion of the antenna? point toward the 

 Hedobiini ; the coxse, however, are contiguous and the general fas- 

 cies is much like some of our species of Ernobius. 



XESTOBIUM Motschulsky. 



The species of this genus are oblong, parallel, moderately stout 

 and of rather more than average size. The men turn is transversely 

 trapezoidal, labrum short and truncate or broadly rounded ante-
