StaphylinidcB of the Amazon Valley. 71 



till the 5th, which is quite black ; the 6th and 7th bright- 

 orange ; segment 2 almost impunctate ; the 3rd rather 

 sparingly and moderately finely, the 4th — 7th evenly and 

 distinctly, but not densely, punctured. Legs yellow. 



Ega ; two specimens, one of which I have ascertained 

 by dissection to be a male, while the other I suppose to be 

 a female. The male carries no external indication of its 

 sex ; the dorsal and ventral plates of the 7th segment are 

 both truncate, with the angles rounded, and without visible 

 crenulations. 



4. Aleochara munda7ia,n. sp. Ferruginea, capite abdo- 

 mineque (apice excepto) nigricantibus ; crebre sat fortiter 

 punctata ; elytris thorace brevioribus. Long. corp. 2| — 

 2f hn. 



Similar in build to A. tristis, but rather larger, very 

 differently coloured. Antennge tawny, the 3rd joint a little 

 longer than the second, 4th short and transverse, 5tli con- 

 siderably broader than the 4th ; after this the joints become 

 no broader, each markedly transverse ; the last joint twice 

 as long as the preceding. Palpi ta"vvny. Head black, 

 half the width of the thorax, moderately distinctly punc- 

 tured, with a well-marked yellow pubescence. Thorax 

 tawny, nearly twice as broad as long, a little narrowed in 

 front, rather closely and finely punctured, with a yellow 

 pubescence. Elytra tawny, very short, considerably shorter 

 than the thorax, rather closely and finely punctured. Hind 

 body tawny black at the base, darker till the 5th segment, 

 which is quite black ; the 6th segment (except the base) 

 and the 7 th orange-coloured ; rather closely punctured, 

 the basal segments more finely than the apical ones; 

 scarcely narrowed till the 6th segment. The legs are 

 yellow. 



This is probably a very common species in the Amazon 

 district, extending from Para to Ega. I have five speci- 

 mens before me, coming fi-om Para, Tapajos and Ega ; 

 one of them bears a ticket, — " in dung." 



Obs. — This species, though very closely allied to A. au- 

 ricorna, is easily distinguished therefrom ; it is a little 

 smaller, and its colours are not quite so brightly con- 

 trasted; the antennas are paler and less stout than in 

 A. aiiricoma, and the pvmctuation of the u]iper surface is 

 a little finer and closer. There are no external marks of 

 the sexes to be seen.
