genus Cixius. Of these, one certainly, and another probably/ belong 

 to Oliarus ; a third is, I think, the type of a new genus ; and the re- 

 maining four I know nothing about, but one or more of them probably 

 do not belong to the genus Cixius. 



70. Oliarus ojipositus (= Cixius oppositus, Wlk.). 



71. O. marginalis (== Cixius mmr/inalis, Wlk.). 



Some specimens from Mr. Wakefield agree pretty well with Mr. 

 Walker's description. 



AKA, n. g. 



Body oblong. Head narrower than the pronotum, vertex obtusely 

 prominent between the eyes, hind margin angularly sinuate, disc with 

 a central longitudinal keel, and on each side a stronger one, which 

 meet each other and the central one at the front margin ; in front of 

 these are three oval pits, of which the central one is much the 

 smallest. Frous and clypeus strongly elliptic, with raised side margins 

 and central keel, which, on the half of the frons nearest the vertex, 

 becomes forked. Antennae small, 2nd joint globose. Eyes emarginate 

 below. Ocelli apparently two. Pronotum with a strong central keel, 

 and one on each side, which, arising from the front margin near the 

 central keel, makes a double curve and ends near the hind angle. Scu- 

 tellum with a central keel vanishing before the apex, and an oblique 

 curved one on each side. Tegmina rather clasping the body, costal 

 margin slightly rounded. Hind tibias unarmed. 



Allied to Myndus, Stal. From the Maori "Aka,'' angular. Type 

 Cixius Jinitimus, Wlk. 



72. Ahajlnitima (= Cixius Jinitimus, Wlk.). 



Mr. Wakefield (four specimens). 



73. Cixius, sp. ? 



Three specimens from Professor Hutton, but not in condition to 

 be described. 



74. Cixius punctimargo, AVlk. 



75. C. interior, Wlk. 



76. C. aspilus, Wlk. Probably not a Cixius. 



77. C. ruffrons, Wlk.
