308 COLEOPTERA 



pubescence on its elytra is rather irregularly arranged, so as to have a 

 somewhat spotted appearance, and is very easily rubbed off. 



I have received some very damaged specimens of this remarkable 

 species from Captain Broun, who found them, I believe, at Tairua, 

 Auckland, and I have seen other individuals from the same source in 

 the collections of Messrs. Pascoe and Wakefield. 



Cyprobius. 



Sharp; Ann. Mag. Nat. Hist., July, 1878, p. 44. 



A single species is also all I can at present assign to this group. It 

 departs but little in its structural characters from Byrrlwdes ; it is, how- 

 ever, of rather small size, and the antennas, are only moderately long ; 

 the head is very short, and the parts of the mouth very little prominent ; 

 and the mentum is rather shorter than it is broad, differing therefore 

 strikingly from that of Byrrhodes gravidus. 



Both by structure and appearance this form connects the group of 

 peculiar New Zealand genera possessing a deep antennal fossa, with the 

 group number 7 of this paper (Cyphon), in which the fossa is absent. 



552. C. nitldUS, Sharp; Ann. Mag. Nat. Hist., July, 1878, 

 /. 44. C. ovalis, haud elongatus, sat convexus, parcius punctatus, 

 nitidus, parcius longiusque pubescens, brunneo-castaneus : antennis 

 minus elongatis, articulo tertio elongato, quam quartus haud duplo 

 breviore ; prothorace perbrevi, anterius in medio rotundato utrinque vix 

 sinuato, angulis anterioribus haud productis, basi rotundata ; elytris 

 parcius punctatis. 



Long., 5 mm. ; lat, 2j mm. 



This species has quite the form and appearance of the species of 

 Cyphon. The pubescence of the elytra is longer and less depressed than 

 in any other New Zealand species here described, but it is rubbed off 

 under very slight friction.

Cyphanus. 



Sharp; Ann. Mag. Nat. Hist., July, 1878,^. 46. 



This group is formed by species which possess the following charac- 

 ters : 



Form rather elongate and narrow, size moderate. Antennae elongate. 

 Head short and broad, the interantennal portion not extended forwards ; 

 the antennal fossce very profound, and at their termination very distinctly 

 separating the gense from the extreme basal portion of the maxillse ; 

 mandibles large, moderately prominent ; labrum exposed, separated by a 

 short membraneous space from the front of the head ; labial palpi 

 strongly furcate i.e., the second joint is so formed that it appears to be 

 the terminal one, the third joint being inserted on the basal portion of
