StaphylinidcB of the Amazon Valley. 257 



short and robust, their teeth smalL Head pitchy, densely 

 and very finely punctured, very delicately pubescent, 

 scarcely shining. Thorax about as long as broad, scarcely 

 broader than the head, and distinctly narrower than the 

 elytra ; densely and extremely finely punctured, so that an 

 impunctate line along the middle is very indistinct, the 

 colour scarcely paler than that of the head. Elytra a good 

 deal longer than the thorax, obscure testaceous, Avith the 

 disc a little infuscate, closely and finely punctured. Hind 

 body very densely and finely ])unctured, quite opaque. 

 Legs yellow ; front tarsi not in the least dilated, hind tarsi 

 with the basal joint a good deal longer than the 2nd. 



The male characters are very slight ; the ventral plate 

 of the 7th segment of the hind body being a little emargi- 

 nate at the extremity in that sex. 



St. Paulo ; three individuals. 



This species appears to be closely allied to the common 

 and widely distributed L. ochracea, but is so much 

 smaller that it cannot be confounded therewith. L. ivfiis- 

 cata, Er., from Columbia, is probably a very close ally of 

 this species, but according to Erichson's description differs 

 in the colour of the hind body. 



4. Lithocharis difflnis, n. sp. Rufescens, capite, 

 elytrorvmi apice abdomineque apiccm versus plus minusve 

 infuscatis, pedibus testaceis, dense subtilissime punctata ; 

 prothorace quadrato, linca media impunctata. Long. 

 Corp. 2 lin. 



Similar in size, form and punctuation to L. ochracea, 

 but with the head larger, it being almost broader than the 

 thorax ; rather larger than L. simplex, and with the labrum 

 furnished in the middle with two obscure distant teeth ; in 

 other respects it appears to agree exactly with L. simplex. 



Tlie 7th segment of the hind body has the hind margin 

 of the ventral plate quite simple in the male, so that I am 

 not aware of any external character by which the sexes 

 can be distinguished. 



Ega ; two specimens. 



5. Lithocharis comes, n. sp. Rufescens, capite tho- 

 raceque obscurioribus, elj-tris sordide testaceis, apice 

 dilutioribus, pedibus testaceis, dense obsoleteque punctata;
