Coleoftera.] SUBANT ARCTIC ISLANDS OF NEW ZEALAND. 115 



Rostrum nearly plane above, obsoletely carinate, rather finely punctured, more 

 closely at the sides. Head finely strigose behind, its punctuation like that of the 

 rostrum, with a linear interocular impression. Thorax subquadrate, very slightly 

 narrowed towards the base and apex, uneven above, there being a shallow median 

 impression and 3 more or less transversal ones near each side, its punctuation 

 moderately fine and close. Scutellum triangular. Elytra oblong-oval, each elytron 

 obtusely tricostate, the intermediate one abbreviated, the others nearly confluent 

 behind ; between these there are some ill-defined transverse elevations ; the serial 

 punctures, rather fine alongside the suture but coarser beyond, become obsolete 

 behind ; their surface more or less minutely sculptured. Underside almost smooth. 

 Head closely transversely strigose. Basal ventral segment broadly impressed ; all the 

 segments more or less impressed at the sides, the 5th with some distinct punctures. 



The apex of the rostrum bears several setae. The surface is not rough-looking. 

 The pygidium is partly uncovered. The ocular lobes, though feeble, are perceptible, 

 but I cannot conceive their use to an insect whose eyes are situated quite beyond 

 their influence. 



J ? . Length (rost. incl.), 9-12 hues ; breadth, 3J-5 lines. 



Adams Island. 



Two specimens were captured by Captain BoUons, of the " Hinemoa," whilst 

 feeding on Ligusticum antipodum in January, 1901. The larger specimen, retained 

 in the Canterbury Museum, is probably the female, with very indefinite elytral costae. 

 The genus seems confined to Adams Island. 



Group RHYPAROSOMIDAE. 

 Hycanus, Broun, 1905. 



Rostrum rather shorter than thorax, stout, broadest and subpterygiate at the 

 point of antennal insertion — ^the middle — so that it appears contracted behind ; its 

 apical portion smooth and shining, the remainder rugose-punctate. Scrohes quite 

 open above in front, directed towards but not quite reaching the eyes. Mandibles 

 prominent, laminate. Eyes almost rotundate, flat, distinctly faceted, just free from 

 thorax, widely distant from each other. Antennae implanted before the middle. 

 Scape stout, clavate, attaining the back part of the eye. Funiculus longer than 

 scape, basal joint only one-third the length of the scape, 2nd distinctly shorter, joints 

 3-7 decrease in length, 4-7 moniliform and hardly at all longer than broad. Cluh 

 oval, triarticulate. Thorax subcylindric. Scutdlum obsolete. Elytra oblong-oval, 

 wider than thorax at the base. Legs of moderate length. Femora clavate. Tibiae 

 simple, their inner angles not prolonged and acuminate. Tarsi rather short, with 

 finely pilose soles, their 3rd joint bilobed, the lobes, however, are short. Prosternum 

 moderately incurved. Ocular lobes obsolete. Anterior coxae prominent and con- 

 tiguous, intermediate moderately separated, the posterior widely. Abdomen elongate ; 

 the basal segment at the sides but little longer than the 2nd ; 3rd and 4th about a 

 third shorter than 2nd ; these and the 2nd with straight sutures ; 5th rather long. 



With some modifications, the only exponent of this genus might be transformed 

 into a Clypeorhynchus. This latter, however, has more slender and much longer 

 antennae ; the eyes, instead of being rotundate, are transverse, their greatest
