OF NEW ZEALAND. 



39' 



prothorax, which is cordate-quadrate, being strongly emarginated in 

 front with obtusely rounded angles, the base broadly emarginated and 

 overlapping the elytra, the sides are rounded in front and sinuously 

 narrowed posteriorly, but with rather prominent though not acute hind 

 angles ; the punctation of its surface is moderately fine and not very 

 close, and there are several larger punctures irregularly distributed over 

 the disc. The e/ytra are a little dilated behind the middle, and are 

 rather closely striated, there being more than fifteen more or less dis- 

 tinct punctured strite on each, their suture is rather broad and smooth, 

 but there are a few punctures near the scutellum. The head is rounded, 

 with the prominent labrum and the epistome emarginate in front, it is 

 punctate. The tihicB are dilated towards the apex. The under-surface 

 is punctate, and the prostefnal process elevated. 



The body is blackish, rather dull, and almost nude. 



Length, 35 lines ; breadth nearly 2. 



Westland. 



695. A. alienum, n.s. Elongate, sub-parallel, slightly convex, 

 setose, obscure castaneous, legs fusco-testaceous, antennae and labrum 

 reddish, palpi yellowish. 



Head not quite immersed up to the eyes, rounded ; the suture of 

 the epistome deep, with a groove proceeding from each side of it to the 

 back part of the head, which, consequently, is uneven, and it has a few 

 moderately coarse punctures emitting fuscous bristles ; the epistome is 

 sub-truncate, and the prominent labrum widely but not deeply emargi- 

 nate in front. 



Protlwrax almost longer than broad, sub-cordate, not margined, 

 widest in front of the middle where it is rounded, and narrowed pos- 

 teriorly ; the base adapted to the elytra but not overlapping them, 

 obtusely rounded in the middle and sinuated at each side ; front and 

 hind angles subacute ; the apex is subtruncate, with a slight emargina- 

 tion behind each eye, and the sides crenate ; there is a broad depression 

 on each side of the middle extending from the base towards (but not 

 attaining) the front, and most obvious near the middle, and its surface 

 bears coarse punctures and bristles. Scutellum indistinct. 



Elytra narrowed towards the prominent, porrected, humeral angles, 

 sinuously narrowed and rather abruptly declivous behind, with a rather 

 flat disc, bearing irregular rows of moderate punctures, and traces of 

 striae near the sides, they are studded here and there with a few granular 

 elevations, whilst the summit of the posterior declivity is obtusely tuber- 

 cular. 



Legs normal, punctate, and clothed with fine yellow setae. 



The antenna; are nearly as long as the head and thorax, robust, 

 pilose ; the exposed part of the basal joint not much longer than the 

 short second joint ; third cylindric, about as long as fourth and fifth 

 conjointly ; fourth to sixth equal, subtransverse ; seventh to tenth 

 obconical, the latter largest ; eleventh larger than tenth, obtusely 

 rounded. 



The prosternal process is broadly impressed longitudinally and the 

 under-surface is punctate (remotely) and finely setose.
