 antennis apicem versus latissimis, basi testacea, apice fusco, articulis 

 5-11 intus productis. 



Long., 5 mm. 



Antenna very short, the third joint slender and rather long, the 

 fourth much shorter and a little angulated internally, the fifth slightly 

 produced, and, like the following joints, very short ; these apical joints 

 are dark in colour, and each is strongly produced inwardly, the eleventh 

 joint being also very short and broad, but not quite so wide as the 

 tenth. The upper-surface is not of a uniform colour, but of different 

 shades of infuscate red, and it is densely clothed with depressed grey 

 and fuscous hairs which obscure the sculpture, and which are not 

 arranged so as to form any definite pattern. The legs are reddish. 



The only specimen I have seen of this very distinct species was 

 given me by Mr. Wakefield, who found it at Riccarton, September 22nd, 

 1873-
