more hairy; body large in size and subparallel, the abdomen relatively 

 narrower than in any of the preceding. [Type Q. explanatus Lee.] 



Megaquedius 



Whether these groups are to be considered genera or not, depends 

 entirely upon the opinion of various systematists; by Dr. Horn, 

 they were not considered as even worthy of numbered or lettered 

 sectional distinction; by the authors of the latest European cata- 

 logue, they are considered subgenera. Quedionuchus was put 

 forward by Dr. Sharp as a fully valid genus, quite distinct from 

 Quedius. Personally I am not only inclined to agree with the 

 latter author in this opinion, but believe it best to consider them 

 all as genera provisionally, although some are more closely related 

 among themselves than others, as in the case of Microsaurus and 

 Distichalius for instance. Possibly one or more of them, as for 

 example Quediellus, may prove to be the American equiva- 

 lents of some European groups which are not represented in my 

 collection just now, but I do not consider this as altogether probable 

 and believe it rather more likely that the European Sauridus Rey 

 is itself composite, as also Raphirus Steph. 



Hemiquedius n. gen. 



The type of this genus and the only species known thus far, the 

 Quedius ferox of LeConte, differs from any other hitherto closely 

 associated with Quedius, in its very parallel form, polished and al- 

 most sculptureless elytra, slender antennae, in which feature it 

 resembles only the equally shining and sculptureless, though 

 otherwise unrelated, Quedius vernix, and, especially, in its sub- 

 quadrate prothorax, which suggests some affinity with Staphylinus. 

 The species has been sufficiently described by Horn (Tr. Am. Ent. 

 Soc., 1878, p. 1 66) and is so well known to all interested in the 

 present tribe, that further notice of it is unnecessary in the present 

 outline notes. 



Quedionuchus Sharp. 



The above remarks in regard to general knowledge of the type, 

 apply also to the Quedius Icevigatus of Gyllenhall, for it is so well 

 known that no further elucidation of it is now necessary. It should 

 be said, however, that longipennis Mann., is a species quite different 

 from IcEvigatus, being more slender, with rufous and much more
