the vertex quite smooth. Thorax convex, transverse, finely margined, 

 the sides rounded, narrowed and slightly sinuated behind, with acute, 

 but not very prominent, hind angles ; the discoidal longitudinal line is 

 not very deeply impressed, the base is depressed at each side, and the 

 intervening space is distinctly punctured. The elytra are very convex, 

 with rounded sides ; each bears six obvious, discoidal, punctured striae, 

 the lateral striae being indistinct, and all are more or less superficially 

 impressed or obsolete near the extremity ; the interstices are broad, and 

 the third is impressed with a puncture in front of the middle. The 

 lateral margins become indistinct before reaching the apex. Characters 

 normal.

I found one example of each sex near Whangarei Heads.

 The following is the description of Count de Castelnau's Drimostoma 

 striatopunctato, which is identical with Motschulsky's Olisthopus insu- 

 laris. Mr. Bates states that it scarcely differs from the common Aus- 

 tralian Ancho menus ambiguus, Erichs. (Cyclothorax id., W. MacleayJ 

 the only difference observable being its more aeneous colouring. 



Dark glossy brown ; thorax almost round, rather transverse; impres- 

 sions moderately marked ; numerous punctiform impressions cover the 

 posterior part ; elytra broad ; oval, convex, covered with striae, formed 

 by punctiform impressions \ inferior margin of the elytra, legs, palpi and 

 antennae of a light red.

NOTE. There can be no difficulty in identifying this species, proba- 

 bly one of the first the collector will find, as I think it is common in 

 most localities. I found it at Auckland, Tairua, and Whangarei.
