(125) I. * Aleochara pallitarsis. Pale-footed Aleochara. 



A. ( pallitarsis) nigra, vix vitida ; thorace orbiculato, subcanaliculato, poslice foveolato .- elytris prothorace longioribus, piceis, 



apice summo rvfis : pedibus piceis tarsis rvfis. 

 Pale-footed Aleochara, black, scarcely glossy ; prothorax orbicular, slightly channelled, posteriorly foveolate : elytra longer 



than the prothorax, piceous, at the extreme tip rufous : legs piccous, with rufous tarsi. 



Length of the body 2 lines. 



Locality unknown. 



This minute insect belongs to Gravenhorst's second family of Aleochara. 7 The 

 species of this genus of minute Brachelytra are so extremely numerous, nearly 200 

 having been discovered in Britain alone, and so difficult to discriminate, that it is 

 not with great confidence that I give this as nondescript. I have many undescribed 

 species in my cabinet that come very near it, but I cannot find one that altogether 

 agrees with it. 



DESCRIPTION. 



Body black, gloss deadened by short inconspicuous hairs. Head rather spherical, narrower than 

 the prothorax, very minutely punctured ; antenna? shorter than the prothorax, rather robust, interme- 

 diate joints turbinate, last joint ovate, acute : prothorax suborbicular with the sides deflexed, very 

 minutely and thickly punctured ; dorsal channel nearly obsolete ; a large punctiform impression just 

 above the scutellum : elytra longer and rather wider than the thorax, piceous-black, extreme tips 

 rufous, very minutely and thickly punctured : legs piceous-black with rufous tarsi.
