genera, but belonging to purely Australian or Antartic forms. Our material, 

 as far as it goes, shows a great specialization of the New Zealand fauna. 

 Thus, out of the total number of thirty-seven New Zealand genera of 

 Geodephaga, no fewer than fourteen are peculiar to the islands; of the 

 remainder, eight are Australian and two are Chilian : seven genera only are 

 common to New Zealand and the north temperate zone; and these are genera 

 of universal distribution. There remain six genera, described as Argutor, 

 Feronia, etc., which I have not yet seen, and therefore class as doubtful. 



Many of the species described or enumerated in the following paper have 

 been communicated by Messrs. "Wakefield and Fereday, of Christchurch, and 

 Mr. Lawson of Auckland; and it is at the desire of these gentlemen and other 

 local naturalists, who are labouring to gather together the scattered materials 

 of the New Zealand fauna, that I have undertaken this task,

This form is generally considered a variety of C tuberculata. The 

 differences, however, are considerable ; for besides the width of the lateral 

 white stripe, which reaches throughout the lateral rim of the elytra, it is a 

 broader insect, with the elytral surface more uniform in colour, and, parti- 

 cularly, the rows of punctures much less marked and with smaller green 

 spots. It must rest with local entomologists to decide, by observing the 

 forms in situ, whether they are distinct or not.

Very similar to C. tuberculata in sculpture, colours, and markings, but 

 certainly distinct. It is always much smaller and narrower ; and although 

 the lateral white stripe of the elytra is very similar in form and direction, the 

 median fascia is prolonged as a curved streak some distance down the disk of 

 the elytron. There is also a structural difference in the apex of the elytra, 

 which may better be expressed by a tabular formula :
