the prosternal process impressed between the legs, and behind them not bent up ; 
its extremity capable of close apposition with the vertical front of the posterior 
part of the mesosternum; metasternum very short; hind coxz broadly separated ; 
the process between them neither truncate nor acuminate in front, but intermediate 
in shape between these two forms; ventral segments as in Adelium ; epipleure 
moderate, gradually narrowed from the base to the apex; legs slender; tibie 
cylindric, smooth; tarsi quite slender, not densely pubescent beneath. 
This is another genus of Tenebrionides, not closely allied to any other; but 
will probably be found allied to some of the little-known forms of the family from 
New Caledonia, such as Isopus. In the New Zealand list it will take its place 
next to Adelium. 
Cerodolus chrysomeloides, n. sp.—Ovalis, niger, supra zneus, antennis pedi- 
busque rufis; capite thoraceque subtiliter punctatis, elytris subopacis, seriatim 
foveolato-punctatis. Long. 7m.m. (Plate xu, fig. 6.) 
Antennz longer than head and thorax; penultimate joint about as long as 
broad ; head scarcely half as broad as the elytra; thorax a little narrowed from 
the base to the front, with a very shght sinuation of the sides in the front of the 
hind angles; these about rectangular, but minutely rounded; the lateral margin 
very fine; the front not emarginate; the base a little sinuate on either side; the 
surface finely and not densely punctate, with a minute depression on the base on 
either side of the middle; scutellum transverse ; elytra convex, each with eight 
series of foveiform punctures, somewhere about twelve punctures in each series ; 
those near the suture and base finer, and those at the apex irregular, so that the 
surface there is quite uneven. Legs, glabrous unicolorous red. 
Greymouth. Helms, No. 377. I first received this insect from Herr Reitter; and, as he wished 
a name proposed for it, I labelled it ‘‘ Adelium? variolosum ;”’ 
be abundantly different from Adelium. 
on investigation it proves, however, to. 
ARTYSTONA. 
Artystona obscura, n. sp.—Elongata, convexa, nigricans, antennis pedibusque 
rufis; capite thoraceque crebre subtiliter punctatis, subopacis; elytris subtiliter 
striato-punctatis, interstitiis versus apicem vix tuberculato-elevatis. Long. 12 m.m. 
The species of this genus are apparently very close to one another in their ex- 
ternal characters, but appear to be subject to very little variation. A. obscura is 
about as large as A. wakefieldi, but broader and less linear, and is readily distin- 
guished by the more opaque and less punctate head and thorax, and the very slight 
development of the elytral tuberculation. 
Bealey. Helms. A. wakefieldi occurs at Christchurch (Wakefield), Dunedin (Hutton), and Picton 
(Helms).
