OF NEW ZEALAND. 97I , 



twice the length of the following one, joints 3-5 transverse ; club 

 well defined, oval, densely pubescent. Thorax a little longer than 

 broad, much narrowed and constricted in front but broad and well 

 rounded behind the middle, base truncate. SmitcUum distinct, 

 quadrangular. Elytra as wide as middle of thorax, parallel. Lega 

 long and robust ; femora swollen and angulated below ; tihicB 

 somewhat expanded towards the extremity, where they are inwardly 

 armed with a spiniform process, their hooks small ; tarsi moderate, 

 pubescent, their penultimate joint expanded and bilobed. 



There is no approximate form amongst the Pentarthridw. The 

 body is like that of Macroscy talus, the rostrum is thick vertically, 

 and the scape is disproportionately incrassate. 



1753- G. rarus, ^'-s. Sub-depressed, moderately elongate; 

 shining, pitchy-red, antennae fulvous ; clothed with yellow and fine 

 greyish hairs, these latter on the elytra. 



Rostrum minutely and densely sculptured, and with some 

 punctures which are most conspicuous near the base. Antennce 

 finely pilose. Head pilose, nearly smooth behind. Thorax rather 

 longer than broad, much narrowed and constricted anteriorly, 

 broadest, and strongly rounded, behind the middle ; rather finely 

 and distantly punctured on the disc, obsoletely impressed down the 

 middle, its apex raised and nearly smooth. Scutellum impunctate. 

 Elytra parallel-sided, as broad as the widest part of the thorax, 

 leaving an evident gap between it and the humeral angles ; 

 bi-impressed transversely, striate-punctate, interstices rugose, the 

 sutural and third elevated behind and continued round the apex. 



^ . Length, 1^ lines ; breadth, nearly f . 



Taken on Mount Egmont. 



Exomesites. 



NooJ. geji. 



Body robust, yet depressed above. Thorax oblong, abruptly 

 contracted just at its apex, base strongly bisinuate. Scutellum 

 minute. Elytra abruptly broader than thorax, base strongly 

 arcuate, gradually narrowed posteriorly. Bostrum stout, gradually 

 expanded till reaching the point of antennal insertion — near the 

 apex — where it is nmch broader ; its scrobes profound, oblique, quite 

 easily seen from above. Antennce moderately elongate ; scape 

 gradually incrassated ; funiculus 7-articulate, first and second joints 

 of nearly equal length; club distinct, ovate. Eyes prominent. 

 Occiput smooth. Legs long, femora inflated; tibiaB laterally com- 

 pressed and wide, apical hooks strongly developed, the inner apex 

 acute ; tarsi elongate and narrow, the penultimate joint but little 

 broader than second, its apex excavated for the articulation of the 

 terminal, and disclosing the small true fourth joint at its base ; claws 

 moderate. 



The legs are like those of the typical Pentarthra (P. zealandicum, 

 for example, but longer) : CoptorliauipMis from Borneo, Lipancylus 

 from South America, Pachytrogus from Chili, Stercomimetes from,
