 tennis capiteque piceis, illarmn summo basi, pcdibusque 

 testaceis ; abdomine fortiter puuctato, iridescente ; elytris 

 crebre, subtiliter punctatis. Long. corp. 2^ lin. 



Much smaller than A. glahricoUis, and very different in 

 colour. Antenna pitchv ; the basal portion of the 1 st 

 joint yellowish ; they are moderately long, scarcely 

 thickened towards the extremity ; 3rd joint much shorter 

 than the 2nd, longer than the 4th ; 5th again longer than 

 the 4th ; i)p to the 9th each joint longer than broad; 10th 

 and Uth joints rather stout, each about as long as broad. 

 Palpi yellowish. Head pitchy black, suborbiculate. 

 Thorax pitchy, a little nan-owed to the front. Elytra 

 reddish or pitchy red, scarcely so long as the thorax ;' to- 

 gether with the scutellum finely and rather closely punc- 

 tured. Hind body reddish, with iridescent tints, roughly 

 and strongly punctured, the points appearing elevated, its 

 pubescence coarse. Legs yellow. 



Tapajos; one specimen. 



QUEDIUS. 



Of this extensiA-e and widely distributed genus it is 

 remarkable that I ha^e received but a single species from 

 the Amazons, and I have only a few others from South 

 America in my collection : as only about five species have 

 been described from tropical America, it seems probable 

 that the species are not numerous there. 



1_. Quedius chjpealis, n. sp. Nitidus, rufo-testaceus, 

 capite ])ectoreque piceis, illo antice rufo, abdomine irides- 

 centi-nigro, parce punctato basi hevi, apice tcstaceo ; ely-

 Long Corp. 4 lin. 



Antennae short and rather stout, clear yellow ; 3rd joint 

 longer than 2nd; 4 — 10 each a little shorter and broader 

 than its predecessor, the j^enultiinate joints rather strongly 

 transverse, and with their upper and inner angle a little 

 produced, so as to be sul)serrate. Palpi yellow. Head a 

 good deal smaller than the thorax, rather short and broad ; 

 the eyes very large, and occu])ying very nearly the whole 

 side of the head, shining, blackish, with the front part 

 broadly yellow, impunctate, except for two or three punc- 

 tures at the margin of the eye. Thorax curved at the 

 sides and a little narrowed in front, about as lono- as
