It is with some doubt that I refer this genus to the Erirhiuiihc. In 

 the form of the hind legs it approaches the two preceding genera 

 ( Stepliauorhyuchiis and Hoplocrionc) ; but the head, not constricted 

 behind to form a neck, would seem to indicate a different type. 

 Ixali/ia, another anomalous genus, with somewhat similar legs, but 

 having a free pygidium, I refer to the neighbourhood of Tac/iyi^oiii/s. 

 M. Roelofs (A?iii. Soc. Belg., xvii., /. 126) places his genus Cc/ia, 

 apparently identical with Ixalma, among the Ei/g/ioi/iides, i.e., with the 

 En'riiinincr. These are all isolated forms ; but I think the pygidium 

 offers a more important character than the separation or the contiguity 

 of the anterior co.\?e. The species described below differs considerably 

 in colouration, some individuals being of an almost uniform dark brown, 

 others pale brown on the disc of the elytra ; some have the elytron 

 prettily variegated — a central dark triangular spot with a light semi- 

 circular line behind, and other variations.

 Tairua (Captain Broun). 



Much narrower than P. variabilis, and apparently an extreme form 

 of the genus. 



Note. — Both species occur at Tairua and Wliangarci Meads. 



Brexius. 



I have not been able to refer to the description of this genus, and I 

 have not a specimen of any of the species belonging to it.
