418 SHarp—On New Zealand Coleopiera. 
Protophormus binodulus, n. sp.—Fusco vel griseo-squamosus, vix variegatus, 
antennis rufis; thorace subcylindrico antrorsum paululum angustato; elytris minus 
elongatis ante apicem binodulosis. Long. 6 m.m. 
Slightly larger and more robust than P. gracilis, and readily distinguished by 
the existence of a longitudinal nodule or elevation on the third interstice, just at 
the commencement of the apical declivity. The surface is densely covered with 
scales varying in colour according to the example, but scarcely at all variegate ; 
the prothorax is elongate, and its surface bears some very obsolete rugze; the elytra 
possess recular series of rather large punctures, and, in addition to the nodule on 
the third interstice, there is a very slight elevation of the fifth interstice, a little 
more to the front than the other elevation. 
Greymouth. Helms, No. 95. Mr. Helms identified the sexes of this species for me by observation 
of the living insects, the male appears to be rather more slender than the female. 
Protophormus robustus, n. sp.—Latior, griseo-squamosus, antennis pedibusque 
piceis; prothorace rugoso; elytris ante apicem nodulosis, apicibus productis acu- 
minatis (an feminee tantum ?) medio ante apicem pallido-squamoso. Long. 8 m.m. 
This is distinguished from the other species not only by its larger size, but also 
by the more uneven surface and broader scutellum. The rostrum is carinate along 
the middle and minutely foveate between the eyes; the surface of the thorax has 
numerous coarse rugee ; the broad elytra also have the surface uneven, and bear- 
ing series of rather coarse distant punctures, each of which is occupied by a more 
pallid scale, the interstices present here and there slight longitudinal elevations, the 
third, fifth, and seventh have each a more distinct elevation at the commencement 
of the declivity, that nearest the suture being much the larger; behind these two 
larger elevations the surface extending to the apex is densely clothed with more 
pallid scales, and on either side there is a large patch of darker—nearly black— 
scales; the apices are prolonged. 
Otago. Professor Hutton; one example. This is probably a female, and from analogy with P. cuspi- 
datus it is possible the male may have the apices less produced. The species bears a superficial resem- 
blance to Catoptes, from which the form ofthe head and anterior parts of the thorax readily distinguish 
it. The tips of the posterior tibiw are even less cavernous than they are in P. gracilis; so that, had it 
not been for my previous knowledge of that insect, I should have considered the corbels as open in the 
present insect, yet a really careful inspection shows that they are truly cavernous in a rudimentary 
manner. The sculpture and form of the insect are very similar to those of Empzotes censorius, Pascoe ; 
but that has a less pterygiate rostrum, with definite scrobes directed towards the front of the eye. 
Nownnortus (noy. gen. Otiorhynchinorum). 
Rostrum breve, crassiusculum, subcylindricum, scrobes brevissime.  Oculi 
magni haud convexi superne minus distantes. 
This is closely allied to Protophormus, from which it differs in the form of the
