Suarp—On New Zealand Coleoptera. 421 
Platyomida simulatrix, n. sp.—Minor, griseo-squamosa, haud variegata; 
prothorace cylindrico, rugoso; elytris interstitio tertio longitudinaliter ante 
declivitatem magis elevato. Long. 6 m.m., 
This is extremely similar to Protophormus binodulus, but the surface is 
more uneven, though the apical nodules are less developed; the scape of the 
antenna is rather short, the apical portion much incrassate, the short broad 
rostrum has on the middle two very short feeble grooves, separated by a slight 
carina; the thorax is remarkably cylindric, and its surface coarsely rugose; the 
elytra bear regular series of rather coarse punctures, and the third interstice has 
an elongate, slight elevation at the commencement of the apical declivity ; 
only a very slight elevation of the fifth interstice can be detected, and this is 
elongate, not in the least nodular. 
Greymouth. Helms, No. 96; a single example. Though so similar to Protophormus binodulus, 
the species will be readily separated therefrom by the deep elongate scrobe attaining very nearly the 
front margin of the eye. It is very closely allied to P. (Empeotes) censoria, Pascoe, but scarcely 
attains the size of the smallest examples of that species, and is readily distinguished by the absence of 
the nodules seen in P. censoria. 
AporoLosus (noy. gen. Otiorhynchinorum). 
Corpus parvum, indumento obscuratum, setosum ; antennze scapo crasso ; ros- 
trum breve, scrobes profundze, foveiformes ; coxz anteriores sat distantes; loba 
ocularia obsoleta. (Plate xi, fig. 10, A. irritus.) 
This genus cannot be associated with Trachyphleeus on account of the 
separated anterior coxz; and, moreover, though the ocular lobes are excessively 
rudimentary, yet it is clear the genus is correctly placed in the group char- 
acterised by the possession of the lobes in question. In Aporolobus the pro- 
sternum is markedly emarginate, the eyes are placed near the thoracic margin, and 
extend slightly downwards rather than forwards; these characters being usually 
correlative with the ocular lobes, and the lobes themselves being faintly in- 
dicated, there can be, I think, no real doubt as to the position of the genus. 
The separation of the front cox is exhibited by only a few genera of 
Otiorhynchidz, though it is here conspicuous. The cox are small and very little 
prominent; the metasternum is excessively short, the second ventral segment 
is of moderate length, and the posterior corbels are not cavernous; the 
mandibular scar is quite perceptible; the tarsi are quite of the Trachyphlceus 
type, very short, with very broad third joint, the lobes of which, however, 
are short. The only species known to me is Trachyphlceus iritus, Pascoe. 
The presence or absence of ocular lobes is at present considered of primary 
importance in the classification of the Otiorhynchid, but if there should prove 
to be many genera in which it is as vague a character as it here is, if will be 
impossible to treat it as a character of primary importance.
