50 COLEOPTERA 



sericeo-nitentibus (praecipue $ ), striatis, interstitio tertio apicem versus 

 puncto majori conspicuo. 

 Long., 3 lin. $ $ . 



Agrees with If. antarcticus in almost everything except size \ Castel- 

 nau giving 2 J- Unes as the length of that species, which agrees with a 

 very large number of specimens that I have examined. " The feeble 

 punctiform impression behind " of Castelnau's phrase also indicates a 

 difference between antarcticus and the present species, in which the 

 interstitial puncture is very large and conspicuous. When the two 

 species are compared, several other points of difference are observable, 

 which it is impossible to render clear by description. 



Described from a single pair ( ^ %') from Auckland. 



A specimen in Mr. Wakefield's collection, ticketed " Tainia, Capt. 

 Broun," and others which I have examined from "Wellington," and from 

 parts of New Zealand not specified, differ from the type described in 

 the sutural apex of the elytra not being notably prolonged, and in the 

 thorax being much less rounded on the sides anteriorly and more 

 gradually narrowed to the base. Some of the specimens have a slight 

 greenish tinge, and others have two basal joints of the antennae clearish 

 red. It is impossible, without much further material, to decide whether 

 we have here to deal with several closely allied species, or only with a 

 single variable one. 



H. australasise, Dejean ; spec. Gen. des Coleop., iv., 386, 1829. 

 Oblong, head and thorax black with a tinge of bronze ; thorax sub- 

 quadrate, rather narrowed in front, both sides foveolate behind, pos- 

 terior angles nearly straight. Elytra obscure, bronzy-green, striate, 

 sub-sinuate behind ; antennae and tibiae at the base brick-red. 



Length, 2f lines ; breadth, i line. 



It comes near to the form anxiits; but it is a little smaller, propor- 

 tionally a little narrower, and its colour is a black, very slightly bronzed 

 on the head and thorax, and a dull greenish bronze on the elytra. The 

 head is a little oblong, almost triangular, a little narrowed posteriorly, 

 smooth, rather convex, and it has on each side, between the antennse, a 

 small, almost rounded, and not very obvious impression. The labruni 

 is of a blackish-brown, a little reddish on the margins. The mandibles 

 are blackish ; the palpi of a dull brown, with the extremity of each joint 

 of a testaceous-yellow, somewhat inclined to red. The antennce are of 

 the latter colour. The eyes are very prominent. The prothoi-ax is 

 broader than the head, not quite so long as broad, a little narrowed 

 anteriorly, slightly rounded laterally, and a little convex ; the longitudi- 

 nal dorsal line is delicate, rather marked, and passing by but little the 

 two transverse impressions, the anterior one is formed like the segment 

 of a circle, and both are but little distinct ; there is on each side of the 

 base an oblong impression, rather conspicuous, the bottom of which 

 seems a little rough, but the sides are smooth \ the anterior margin is 

 slightly indented ; the front angles are rather rounded, the sides are 

 finely margined ; the posterior angles are almost rectangular, and their 

 apex a little obtuse ; the base is very slightly indented at the middle,
