474 Mr. D. Sharp on the Elateridas of Neio Zealand. 



37. Ghrosis elongata^ n. sp. 



C. fusca, elongata, minus parallela, evidenter laxe fusco-pubes- 

 cens ; thorace paulo longiore quam latiore, crebre punctato; elytris 

 leviter striatis striis punctatis, interstitiis crebre subtiliter punc- 

 tatis, elongatis, apicibus attenuatis et prolongatis, angulo extemo 

 magis prominulo, minute spinoso ; prosterni lateribus crebre 

 punctatis ; lamina cosali interne evidenter latiore, margins pos- 

 teriore supra trochanterem sat evidenter emarginato ; antennis 

 tarsisque gracilibus, elongatis. Long. 16 m. m. 



This species comes very close to extreme forms of Chrosis 

 harhata^ but is more elongate in form, and has the tarsi espe- 

 cially more elongate. 



Sent from Auckland by Mr. Lawson ; and also received 

 from Mr. Edwards, but without number. 



Group 11. — Species 34, 35, 36, and 37 exhibit the fol- 

 lowing characters : — 



Clypeus short, quite unfolded and extended, so that the 

 forehead is not limited at all from the clypeus in the middle, 

 and the large labrum is almost on the same level as the fore- 

 head ; antennal spaces very indistinct and very widely sepa- 

 rated from one another. Antenna with 2nd and 3rd joints 

 elongate. Prosternal process broad and stout, not curved 

 upwards behind the coxse. Mesosternal cavity with strongly 

 elevated borders ; these attain the intercoxal suture, and their 

 hinder portions are quite horizontal. Coxal plate with tro- 

 chanteral portion a good deal longer than the femoral portion, 

 the long portion occupying about half the whole width, and 

 thence gradually narrowed till it meets the episternum. Tarsi 

 with all the joints simple and well developed, the fourth, 

 however, a good deal shorter than the third. 



It is doubtful whether the genus Chi-osis be distinct from 

 Corynibites as defined and limited by Cand^ze. Indeed our 

 European Elater impressus {Corymhites impressus, Cand^ze), 

 appears more nearly allied to the New-Zealand Ghrosis har- 

 hata than it is to the Elater aidicus and other European 

 Coryvihites. 



38. Elater zealnndicus, White. 



E. rooustus, niger, fiisco-pubescens, sat nilidus ; antennis minus 

 elongatis, intus leviter serratis, articulo secundo brevissimo, tertio 

 sat elongato hand serrate ; prothorace crassiusculo, antrorsum 

 convexiusculo, postice latiore, angulis posterioribus subuncatis, 

 t'oi titer plicatim elevatis, margine laterali anterius a supra oc- 

 culto, crebre aequaliter punctato ; elj-tris striatis, striis fortiter
