In general appearance strongly resembles E. artiplipeti, but with 

 the prothorax black, the head hairy, and the front legs different. 

 The head appears to be rather flat, and, in places, foveate, but 

 its sculpture is gi'eatly obscured by the clothing. 



Rybaxis Macleayi, n sp. 



(J. Reddish-castaneous, head sometimes dark; antennae with 

 apical joint flavous, some of the preceding joints black or blackish. 

 With short, pale pubescence. 



Head moderately large; with two fairly large, round, closed 

 fovea? between eyes, and a moderately deep impression or open 

 fovea in front. Antennte with first joint rather long, fifth slightlv 

 longer but tliinner tlum fourth, sixth alxmt as long as fourth; 

 seventh the length of sixth, but considerably wider; eighth small 

 but transverse; ninth moderately large, transversely suboblong; 

 tenth longer but not wider than ninth; eleventh scarcely as long 

 as ninth and tenth combined, its apex slightly produced on one 

 side. Prothorax feebly transverse, widest at apical third, with a 

 very feeble medio-basal fovea, but a distinct curved impression 

 continued to each side from same, each impression terminating in 

 a large fovea. Elytra almost as long as wide, each with the 

 sutural stria distinct, the dorsal distinct to near apex, at its apex 

 directed slightly outwards; epipleural furrow deep, lightly curved, 

 not quite exte?iding to ba.se or apex; punctures rather indistinct. 

 Metasternum widely impressed in middle, each side with an obtuse 

 tooth overhanging the posterior coxa. Abdomen flattened along 

 middle of under-suiface. Zct/.v rather stout; trochanters unarmed; 

 front tibiae dentate slightly nearer base than apex. Length 2-2| mm. 



$. Differs in having the head smaller, antennae shorter, third 

 to eighth joints subequal in size, tenth considerably larger and 

 wider than ninth, and eleventh longer than ninth arid tenth com- 

 bined; metasternum unarmed and much less excavated alonj'
