OF NEW ZEALAND. 297 



The very narrow parallel form, the very highly polished prothorax, 

 excessively scanty pubescence, and the almost impunctate interstices of 

 the elytra, very readily distinguish this species from its allies, even with- 

 out any examination of structural details. 



Tairua, but very rare ; one individual found by Captain Broun under 

 a log near Pipi Creek, and three others under bark in the same locality. 



OBS. The two specimens sent me by Captain Broun are, I am 

 pretty sure, the two sexes, though they are extremely similar to one 

 another ; they both show the peculiarity of a well-marked notch or 

 emargination at the apex of the last ventral segment. 



528. C. reversa, Sharp; Ann. Mag. Nat. Hist., May, 1877. 

 C. sat elongata, minus parallela, nigra vel picea ; thorace quam latiore 

 paulo longiore, disco obsolete punctate ; elytris latius striatis, striis 

 externis evidenter punctatis, interstitiis sub-convexis, crebre punctatis, 

 apicem versus evidenter attenuatis, apicibus ipsis angustis, haud vel vix 

 prolongatis, angulis internis haud vel vix spinosis; prosterni lateribus 

 nitidis impunctatis ; afafomiwp&tce punctato; lamina coxali interne 

 evidenter latiore, sed margine posteriore supra trochanterem tantum 

 obsoletissime emarginato. 



Long., 16-17 mm. 



The polished impunctate sides of the prosternum readily distinguish 

 this species. 



Described from a single specimen sent by Mr. H. Edwards, under 

 Number 1337 ; one of two individuals sent by the same gentleman under 

 Number 1340 I believe to be the female of the species, though it is very 

 much broader and has the thorax considerably larger and broader. A 

 second individual, which I believe to be a variety of this same sex, is in 

 Mr. Wakefield's collection from the Otira Pass. 



529. C. barbata, Candhe. Sharp ; Ann. Mag. Nat. Hist., May, 

 1877. C. nigricans, colore variabilis, ssepe rufescens, minus parallela, 

 breviter fusco-pubescens ; thorace latitudine longitudinem sequante, 

 crebre punctato ; elytris leviter striatis, striis evidenter punctatis, inter- 

 stitiis crebre punctatis, apicem versus evidenter attenuatis, apicibus haud 

 prolongatis, vel simplicibus vel obsolete spinosis ; prosterni lateribus 

 crebre punctatis ; lamina coxali interne evidenter latiore, margine poste- 

 riore supra trochanterem tantum obsolete emarginato ; antennis pedi- 

 busque minus elongatis. 



Long., 13-19 mm. 



This is an exceedingly variable species. It is closely allied in structure 

 to our European Elater impressus and the small specimens are some- 

 what similar to it in appearance, but have the elytra much more attenuate 

 posteriorly. 



Very widely distributed ; I have seen specimens from Otago and 

 Auckland, and various intermediate localities. 



OBS. M. Candeze described this species as being found in New 

 Holland ; but Mr. Janson believes all the specimens are from New 

 Zealand ; so that it is very doubtful whether the species exists in 

 Australia.
