Broun. — New Genera and Species of Coleoptera. 109 



Length (rostrum inclusive), 4^ mm. ; breadth, 2 mm. 



Titahi Bay, near Wellington. Another of Mr. O'Connor's captures. 

 The specimen described above has been thoroughly cleaned with benzine, 

 but in its natural state is paler and less variegated. 



Agatholobus gen. nov. 



Rostrum as long as thorax, half its width, not pterygiate. Scrobes 

 broad and open above in front, beginning at the apex, directed obliquely 

 downwards, but not reaching the eyes. Head short, not much broader 

 than the rostrum, globose underneath. Eyes subdepressed, transversal, 

 obliquely oval, just free from the thorax, widely separated from each other. 

 Scape inserted near the apex, very gradually thickened, attaining the 

 middle of the eye. Funiculus 7-articulate, basal joint slightly longer than 

 2nd, joints 3-7 obconical, gradually shortened, the last, nevertheless, is 

 not transverse. Club elongate-oval, triarticulate. Thorax subquadrate, 

 base and apex truncate, with strongly developed ocular lobes. Scutellum 

 small or obsolete. Elytra oblong, with oblique shoulders, so that the base 

 hardly exceeds that of the thorax in width, much narrowed and quite 

 vertical behind. 



Femora simple, moderately clavate. Tibiae slightly flexuous, mucro- 

 nate. Tarsi finely setose, basal joint slightly longer than 2ud, penultimate 

 moderately expanded and bilobed, finely and densely setose underneath. 



Prosternum incurved in front, with a small diamond-shaped process 

 behind the contiguous coxae. Mesosternum with a moderate process ex- 

 tending half-way between the intermediate coxae. Metasternum short. 

 Basal ventral segment longer than 2nd, broadly rounded between the widely 

 separated coxae, 3rd slightly longer than 4th. Mentum large, occupying 

 the buccal cavity. Palpi invisible. Posterior corbels with double cilia, 

 the truncate interval very narrow. 



The single exponent differs from all the other genera of the group known 

 to me in facies and structure. The rostrum is unlike that of the European 

 Otiorhynchus, which, moreover, is without ocular lobes. It is most nearly 

 allied to Inophloeus, but differs therefrom in general appearance, and in the 

 form of the rostrum, posterior corbels, &c. ; the ocular lobes, however, 

 are equally prominent. 



3276. Agatholobus waterhousei sp. nov. 



Opaque, nigrescent ; thorax and elytra almost entirely and densely 

 covered with small, depressed, dark-fuscous squamae which have a peculiar 

 silky gloss ; on the posterior declivity and a large space at each side, 

 behind the posterior femora, the scales vary from ye Ho wish -grey to fusco- 

 testaceous ; rostrum wholly covered with cream-coloured squamae ; the 

 legs, except the fuscous basal half of the femora, are clothed with yellowish- 

 grey scales and setae ; antennae and terminal joint of tarsi piceo-rufous. 



Rostrum subparailel, not dilated apically, with shallow longitudinal 

 grooves separated by a slender median carina, which terminatts in a linear 

 interocular impression. Thorax slightly swollen laterally near the front, 

 behuid that part nearly straight, being just a little narrowed towards the 

 base ; disc slightly uneven, with a median groove from base to apex which 

 is deeper and more expanded before and behind than at the middle ; a few 

 inconspicuous, elongate, obscure tawny scales are sprinkled over the surface, 

 but no punctation is visible. Elytra more than double the length of the
