Black, shining, glabrous: heail rather coarsely punctured: thorax very thickly 

 punctured, the punctures smaller than on the head: elytra punctured, 

 pitchy-red, with the base and lateral margins rather dusky : abdomen with 

 a reddish tinge on the margins of all the segments, especially of the penul- 

 timate, and the entire apical one pitchy-red : legs entirely pitchy-red ; 

 anteiinse the same : palpi, labrum, atid mandibles, the same, the apex of the 

 latter dusky. ^ 



Of this fine insect I have seen but one specimen, which was taken 

 in the " New Forest, June 1832."— ^ei'. G. T. liudd. 



Genus DXXII. — Sunius, Leach. 



Antennce filiform^ with the basal joint large, thickened, second short, obconic, 

 third and fourth rather longer, subclavate, remainder gradually decreasing 

 in length to the tenth, subturbinate, eleventh as long as the second, and 

 obliquely acuminated. Palpi maxillary, with the third joint incrassated, 

 truncate; apical minute: labrum entire: head subquadrate : eyes small: 

 thorax subquadrate, with the angles rounded : elytra somewhat depressed : 

 abdomen with the penultimate joint longest : legs moderate ; tihiw simple ; 

 tarsi pentamerous, wdth the fourth joint entire; the anterior slightly 

 dilated. 



The depressed subquadrate thorax of the Sunii, combined with 

 the simple fourth joint of the tarsi, small eyes, simple tibiae, and fili- 

 form palpi, serve to distinguish them from the other true Stenidae, as 

 the two first characters alone do from Astenus, with which genus they 

 have usually been associated. The species frequent shady places, 

 and are found beneath stones, rotten leaves, moss, &c., not unusually 

 in winter and spring.
