^Ir. D. Sharp o/i the Elateridfe of New Zealand. All 



colour, and presents a sli<i^lit diftercncc in the structure of the 

 mcsostcrnal cavity ; in Elaier myops the hinder border of the 

 cavity is distinctly more elevated than the middle portion, 

 whereas this is scarcely at all the case in Elater strangulatus. 

 Tairua; sent by Captain Broun as no. 18. 



• Group 13. — The form of the head is in tlicse species that 

 described in Group 1 1 ; but the present species differ from 

 those of that group by the form of the prosternal process and 

 mcsostemal cavity. The former is but little [Corymhites anti- 

 jiodiim and C. dubius) or not at all {E/atcr strangidatus and 

 myops) bent upwards ; and the saltatorial mucro is much pro- 

 longed. The borders of the raesosternal cavity are not ele- 

 vated ; tlie cavity does not extend to tlic intercoxal suture ; 

 its hind portion is rounded ; and tlie portion of the mesoster- 

 num between the opening and the intercoxal suture is some- 

 what, but only slightly, depressed. Most of the other charac- 

 ters resemble those of Group 1 1 . 



43. Elaier olhascens^ White. 



E. siibaenescens, longius grisco-pubcscens, pedibus flavis ; antennis 

 nifescentibus, tenuibus, minus clongatis, baud serratis, articulis 

 secundo et tertio subDequalibus a sequentibus vix discedentibus ; 

 prothorace minus gracili, postice latiore, subtiliter punctato ; 

 clytris profuudiua striatis, striis cxternis punctatis, intcrstitiis 

 parce subtilissime punctatis, apicibus minute spinosis. Long. 

 9-11 m.m. 



This species is abundant at Auckland and Tairua, and is 

 found on Leptospermum. 



Ohs, This species has also been called Chrosis nneola by 

 Cand^ze. 



44. Corymhites agriotoides^ n. sp. 



C. rufo-fusoulus, longius grisco-pubescens, antennis pcdibusque tes- 

 taceis ; illis tenuibus, simplicibus, articuHs secundo ct tertio 

 elongatis, sequentibus simiUbus ; prothorace convexiusculo, mar- 

 gine lateraU indistincto, parcius minus subtiliter piuictato ; elytris 

 striatis, sed sculptura pubescentia obtccta, apicibus fere muticis. 

 Long, 6^-9^ m. m. 



This is a very variable species, and closely allied to Elater 

 oli'vascens, but may be readily distinguislied by the different 

 colour, nan-owcr form, more convex ])rothorax, Sec. 



Abundant at Auckland and Tairua : found on shrubs.
