54 Mr. F. P. Pascoe on new Genera and 



Ieenimus. 

 Rostrum parum elongatum, modice robustum, versus apicem maui- 

 feste crassius, apice triacgulariter emarginato ; scrohes breves, 

 apicales. Antennce graciles ; scapus prothoracem attingens ; funi- 

 culus articulo prirao vix incrassato ; clava distincta. Oculi sub- 

 tenuiter granulati. Prothorax subcylindricus, basi rotundatus, 

 lobis ocularibus parum prominulis. Elytra elougato-cordata, basi 

 protborace manifeste latiora, humeris obliqiiis. Femora crassa ; 

 tihice flexuosse, posticae corbellis subcavernosis. Abdomen seg- 

 mentis duobus basalibus ampliatis. Corjnts squamosum. 



Allied to the Australian genus Perjyerus, differing princi- 

 pally in the base of the elytra exceeding the width of the pro- 

 thorax at the base. This is a character on which Lacordaire 

 lays great stress ; but in many genera it really seems to be 

 only of specific importance. 



Trenimus parilis. 



I. oblongus, niger, squamis obscure cervinis omnino dense tcctus, se- 

 tulisque nigris adspersus ; rostro capite duplo longiore, antice 

 cariaato ; antennis ferrugineis ; seapo squamoso ; funiculo arti- 

 culis tribus basiilibus sensim brevioribus, caeteris obconicis ; pro- 

 tborace parum longiore quam latiore, lateribus rotundatis, pone 

 medium subijarallelis ; scutello inviso ; elytris seriatim punctatis, 

 intei'stitiis vix convexis, tibiis subbisinuatis, apice subacuminatis. 

 Long. 85 lin. 



Hah. Christchurch. 



Lyperobius. 

 Molyti affinis. Rostrum validum, rotundum ; mundibulce lamelli- 

 formes ; scrohes obliqiice, oculos vix attingentes ; clava distincta. 

 Prothorax lobis ocularibus paulo prominulis. Mytra ovalia. 

 Femora incrassata ; tihi<x apice baud laminataB. Abdomen seg- 

 ment© secundo quam tertio paulo longiore. 



With nearly all the characters of the European Molytes^ this 

 genus is principally distinguished by the tibiffi being without 

 that peculiar external prolongation of the lamina which nor- 

 mally forms the floor of the hollow (corbel) above which the 

 tarsus is inserted, and also by the club of the antenna3 being 

 distinctly marked off from the funicle. The fine species con- 

 stituting the only exponent of the genus at present has been 

 recently discovered by Capt. Hutton at Tarndale, near the 

 head of the river Wairau, in the Nelson province. " It lives 

 on the spear-grass [Acijjhylla Colensonis), and sucks its tur- 

 pentiny juices. The plant only grows on the mountains from 

 2000 to 5500 feet elevation." The insect is entirely black ; 

 but some of the specimens are sprinkled with a few fine straw- 

 coloured hairs.
