244 AUSTRALIAN PSELAPUIDJ:, 



This species much resembles bipartitus in the general shape of 

 the body; however, the antennae are more cylindrical, the punctua- 

 tion is more apparent on the prothorax and the elytra, the 

 abdomen is not angularly contracted on the sides, but the lateral 

 carina is abruptly ended by a transverse groove, and its two 

 margins are nearly parallel. The £ i s n °t known.

Articerus falcatus, n sp. 



(Plate x., fig.25.) 



This species is very similar to curvicomis, Westw.; and it was 

 looked upon by Dr. Schaufuss as the $ of curvicomis, but of this 

 latter I have both sexes, and this species is evidently different. 

 The shape of the body is practically the same, but the punctuation 

 in falcatus is much stronger and more ocellate. The antennse 

 are very different; they are a little shorter, as broad as the head, 

 compressed, very slender at base, rather abruptly ampliated and 

 rotund outwardly and a little curved inwardly, the widest part 

 being at the apex; it is obsoletely and longitudinally impressed 

 above, and has beneath a rather deep and oblong impression; the 

 feet are alike, but the internal apical spur of the intermediate 

 tibiae is not so strong.

To illustrate the differences I give the figures of the antennae 

 of both falcatus and curvicomis, g.
