piiiicttiatlon, Avliieli is close, but the interstices are quite 

 distinct ami not at all niji^ose ; its depressed ])ubesccnce is 

 of a dark colour, but not altof]jethcr black; in colour it is 

 similar to the head. The elytra are just as long as the 

 thorax, and are covered Avith a blackish tomentum, -whicli 

 makes them a])]^ear quite dull and Avithout sculpture, and 

 they bear besides a rather close depressed pubescence. 

 Hind body black, with the two ai)ical segments bi'ight 

 yellow, but the base of the 6th black ; the black part is 

 covered with a dense dark tomentum, which is quite uni- 

 colorous ; the anal styles are yellow. The legs are short 

 and stout, black. The under face of the hind body is 

 distinctly punctured, and bears a rather scanty yellow 

 pubescence ; it has a slight metallic reflection. 



Ega ; seven individuals. 



Obs. — I at first considered this species a variety of 

 S. subcT/aneus, but, after examination of a series of seven 

 individuals, I consider it likely to ])rove a distinct species; 

 it is considerably smaller, rather darker in colour, has the 

 head smaller, and the basal portion of the 6th segment of 

 the hind body black. The male characters appear very 

 similar. 



3. Staphylinus ocliropygus, Nord. var. 



Tapajos, Ega, St. Paulo. 



I identify this species from the descriptions of Xord- 

 mann and Erichson; the S])ecimcns agree therewith except 

 that they have the legs and antenna} paler in colour. 



4. Staplnjlinns gratiosus,w. sp. Fulvus, capite thorace- 

 que viridi-cyaneis, nigro-pubescentibus, scutello atro- 

 tomentoso, abdomine aureo-tomentoso, antennis (basi 

 excepto) infuscatis. Long. corp. 7| lin. 



Mas : abdomine segmento 7° ventrali apicc medio late 

 sed minus profunde emarginato. 



A very pretty species, and remarkable for the peculiar 

 sculpture of the head and thorax, the interstices of the 

 coarse punctures thereon being finely pimctured. An- 

 tennjE stout, about as long as head and one-third of thorax; 

 the two basal joints dark yellowish, the others infuscate ; 

 2nd and 3rd joints rather long, the 3rd longer than 2nd, 

 5 — 10 transverse; last joint truncate at the extremity and 

 pointed on one side. Palpi yclloAvish ; mandibles pitchy. 

 Head narrowed in front, naiTowcr than the thorax, shining
