individual from l*ara ao;rees witli tlie males from Ega, but 

 has the antennai a little stouter and the ]ienidtimate joints 

 more strongly transverse, and the middle joints each a 

 little produced on the inner side. I consider this indi- 

 vidual is only a variety of B. decipiens.

Para, Tapajos, Ega. 



This is one of the commonest and most widely distri- 

 buted of the New World Staphylinidce ; it extends from 

 Pennsylvania to Rio de Janeiro. 



7. Beloiiuclius chjpeatus, n. sp. Niger, nitidus, ano 

 testaceo, prothorace serie dorsali 5-punctato, lateribus sub- 

 rectis, abdomine minus crebre pimctato. Long. corp. 5 lin. 



Mas : clypeo antice vere bidentato, femoribus posticis

Fem. latet. 



Allied to B. decipiens, but distinguished by its more 

 sparingly punctured hind body and the two teeth of the 

 clypeus in the male. The antenn;\; are short and stout, 

 black, with the base pitchy ; 3rd joint slightly longer than 

 2nd ; 4th joint small ; 5th broader than 4th, but also small ; 

 6th joint transverse, 7 — 10 rather strongly transverse. 

 iMandibles nearly black; palpi ])itchy. Head about as 

 broad as the thorax, black and shining, with two short, 

 stout teeth (in the $ if not in the 2) projecting forwards 

 but not upwards from the front part ; between the eyes 

 with four ])unctures, also with four or five other ])unctures 

 close to to the ))ack part of the eyes, and a iew others near 

 the hinder angles. Thorax narrower than the elytra, 

 (juadrate, about as long as broad, not narrowed behind, 

 and scarcely sinuate at the sides, the front angles not 

 rounded; it is black and shining, has on each side the 

 middle a dorsal row of five punctures — of these the hind 

 one is a little the more remote, — and Avith four or five other 

 punctures lU'ar the front angles. Scutellum rather coarsely 

 ])uiu'turi'd. Elytra a little longer than the thorax, black 

 and shining, rather finely and sparingly ])unctured. Hind 

 body black, with the hind portion of the 6th and the whole 

 of the 7th segment reddish-yellow; it is rather coarsely and
