OF NEW ZEALAND. 85 



with two large, but indistinct, shallow impressions between the eyes, 

 which are not prominent ; epistome distinctly emarginated. 



Prothorax convex, of the same form as that of the preceding species ; 

 its punctation very similar to that of the head, but a little finer. 

 Sciiielhiiii triangular, rather elongate. Elytra convex, quite twice the 

 . length of the thorax, each with ten rows of punctures ; these are quite 

 distinct near the suture, are coarser near the sides and apex, and some 

 of the outer do not quite reach the base ; the interstices are much more 

 finely and rather closely punctured, so that the rows are very obvious ; 

 they are finely margined, but not dilated. 



The maxillary palpi are rather stout, shorter than the antennae, 

 their last joint not longer than the penultimate. The basal joint of the 

 antennce is not more than twice the length of the second, which is 

 stouter but scarcely longer than the rather elongate third joint, the latter 

 is nearly as long as the next two, these are stouter than the third, but 

 smaller than the sixth ; the club is rather longer than joints two to six 

 collectively. 



The hind tarsus is stout, the basal joint is not much exposed, the 

 second is the largest, not much longer than fifth ; they are all clothed 

 with golden hairs ; the inner side of the posterior tibia bears some large 

 and other smaller punctures, the larger near the middle, leaving an 

 almost smooth line near the outer edge ; the intermediate tibial are 

 more coarsely sculptured ; the anterior are punctated and somewhat 

 grooved near the outer edge. 



The mesosternal process is elevated but narrow ; the middle of the 

 metasterniun is obtusely elevated and coarsely punctured. 



Length, 2| ; breadth, \\ lines (set out). 



I have five examples before me ; they were found near Whangarei 

 Harbour. 



Cyloma. 



Sharp. 



I have not been able to refer to Dr. Sharp's description of this genus, 

 but I have now before me a duplicate specimen of one sent to him some 

 time ago, which he informs me is his Cyloma lawsonus. 



The insect is somewhat similar in form to the Cydonota described 

 above, but the antennte are only eight-jointed ; the basal joint is sub- 

 cylindric and nearly as long as joints two to five ; the second is oviform, 

 rather narrower at the apex than at its base ; third slender at base, sub- 

 cylindrical, about as long as the second ; fourth short, sub-globular ; fifth 

 short, broader than the fourth ; club three-jointed, large, longer than 

 joints two to five, its basal joint smallest, longer than broad, the last 

 obtuse. Maxillary /<?/^/ moderate ; second joint large, incrassated and 

 bent ; third and fourth about equal, the last sub-cylindric with the apex 

 obtuse. Eyes prominent ; mandibles rather long. 



156. O. lawsonus. Sharp. This is a convex insect, of a 

 pitchy colour, with reddish marginb ; the legs are pitchy red ; tarsi red ;
