pedibusque testaccis, elytris thorace brevioribus anoque 

 obscure rufis ; thorace crebre minus siiljtiHter punctato ; 

 abdomine apicem versus subattenuato. Long. corp. 3^ liu. 



Allied to A.fuscipes, and almost equal in size thereto, 

 but rather more slender, and with the red of the extremity 

 of the hind body more distinct. The antennae are short 

 and stout, the three first joints yellow ; the 3rd a Httle 

 longer than the 2nd ; the 4tli strongly transverse, but 

 much narrower than the 5th ; the rest strongly transverse, 

 slightly narrower after the 7th to the extremity ; last joint 

 quite twice as long as the preceding one. Palpi obscurely 

 yellowish. Head narroAv, scarcely half so wide as the 

 thorax, rather coarsely but not closely pimctured. Thorax 

 narrowed to the front, its breadth quite one and a half 

 times its length, closely and strongly punctured. Ehira 

 considerably shorter than the thorax, reddish, closely and 

 rather strongly punctured. Hind body slightly narrowed 

 to the extremity ; 2nd and 3rd segments sparingly and 

 finely punctured, the i-est coarsely but not closely ; the 

 7th segment and the hind portion of the 6th reddish. 

 Legs dull yelloAvish. 



Tapajos ; one specimen, Avhich is, I have no doubt, a 

 female. 



Obs. — Though closely allied to A. prisca, this species 

 may be readily distinguished from it by the pale basal 

 joints of the antennae 



3. Aleochara auricoma, n. sp. Rufo-testacea, fulvo- 

 pubescens, capite nigro, antennis abdominisque segmentis 

 2 — 5 nigricantibus ; elytris thorace brevioribus ; abdomine 

 segmentis 3 — 7 sat crebre punctatis. Long. corp. 4 lin. 



Antenna? blackish, with the a])ical joint blackish-yellow, 

 stout ; 3rd joint one and a half times the length of the 

 2nd ; 4th scarcely so long as broad ; 5 — 10 strongly 

 transverse ; last joint elongate, rounded at the extremity, 

 more than twice as long as the tenth. The head is black, 

 rather strongly but not closely punctui-ed. The thorax is 

 yellow, ample, its l)rendth one and a tliinl times its length ; 

 its base and hind angles mueli rountled, narrower in front 

 than behind ; it is moderately, finely and closely punc- 

 tured, wifliout chamiel or fovea. The elytra are not more 

 than two-thii'ds the length of the thornx, Avith a similar 

 colour and puiictuati(Ui to it. The liind body is i)itehy- 

 red at the extreme base, the segments becoming darker
