410 Mr. D. Sharp on the Elateridee of New Zealand. 



ral characters such as to require its isolation from the other 

 New-Zealand allies. The forehead is much curved in front, 

 so as to be somewhat produced in the middle, it is sharply 

 defined by a scarcely elevated line, which overhangs the cly- 

 peus, so that there is an abrupt step between the front and the 

 labrura ; the antennal spaces are very obscure ; the antennae 

 are slender, with 2nd and 3rd joints only moderately deve- 

 loped. The prosternal sutures are not distinctly duplicate, 

 and are not open in front, but show there a peculiar sinuatlon. 

 The prosternal process is short, and is abruptly and greatly 

 bent upwards immediately behind the cox?e. The middle 

 coxEe are only narrowly separated ; the mesosternal cavity 

 shows no distinct lateral edge, and is quite depressed ; its 

 opening behind is narrow and ill-defined, and does not reach 

 the intercoxal suture ; the posterior portion, however, is pro- 

 longed backwards as a broad shallow depression on the hind 

 part of the mesosternal process. The femoral portion of the 

 coxal plate is excessively short, in fact linear ; the trochanteral 

 portion is moderately large. The tarsi are moderately short, 

 and all the joints are simple ; the 4th is small but not minute. 

 I think the genus should be placed near Betarmon, from 

 which it differs strikingly by the prosternal process and meso- 

 sternal cavity. 



17. Lomemus filicornis^ n. sp. 



L. EBgustulus, minus nitidus, evidenterpubescens, niger, prothoracis 

 angiilis posterioribus pedibusqiie testaceis, tibiis versus apicem 

 fuscis ; antennis elongatis, tenuibus, sed intus serratis, longius 

 pilosellis, articulis secundo et tertio brevissimis, quam quartus 

 conjunctim multo brevioribus ; prothorace antrorsum angus- 

 tato, crebre fortiter punctato, sat elongate, angulis posteriori- 

 bus subuncatis ; elytris striatis, striis punctatis, apice summo 

 obsoletis, interstitiis punctatis. Long. 5 m. m. 



The pilose antennse, the black colour, with yellow legs and 

 hind angles of the thorax very readily distinguish this 

 species. 



Three specimens have been cut out of a tree-stump at Tairua 

 by Captain Broun ; one of them he sent me with the No. 13 

 attached.

L. angustulus, evidenter pubescens, sat nitidus ; antennis tenuibus, 



fuscis, basi testacea, articulis secundo et tertio sat brevibus, 



conjunctim quarto aequalibus ; capite nigro, fortiter profundeque 



punctato ; thorace sat elongato, antrorsum leviter angustato,
