Broun. — Revision of the New Zealand Cossonidfe. 175 



frontal constriction less deep and a little fnrther from the apex ; the disc 

 rather more closely and distinctly pimctate. Elytral striae rather deeper, 

 interstitial punctures more distinct. 



2 . Length, if lines ; breadth, f line. 



Wellington. Unique. 



Macroscytalus, Broun. Man. N.Z. Coleopt., p. 736, 



Body rather broad, subdepressed, minutely and scantily pubescent. 



Rostrum more than half the length of thorax, moderately stout, narrowed 

 behind the middle in both sexes. Occiput sharply limited at the sides close 

 to the eyes ; the punctuation of the head ceases abruptly in line with these 

 organs. Scape stout, medially inserted, subclavate near the extremity, 

 it attains the front of the eye. Funiculus short, 2nd joint nearly as 

 long as the short basal one, 3-5 compact, transverse. Club oblong-oval, 

 acuminate, as long as or longer than the funiculus, distinctly pubescent. 

 Eyes large, slightly prominent, subtruncate behind, widely separated. 

 Thorax rather short and broad, its sides strongly rounded ; the moderate 

 frontal constriction at each side extends obliquely towards the median 

 discoidal linear impression. Scutellum small but distinct. Elytra rather 

 short, subparallel or very slightly curved laterally, rather broader than the 

 base of the thorax. Legs moderately stout ; hooks of the tibiae well de- 

 veloped, inner extremity with a sharp calcar ; tarsi moderate, penultimate 

 joint excavate but not lobed. 



This genus should follow Bhinanisus. The rather broad subdepressed 

 Ijody and remarkably large antennal club, apart from other details, are 

 characteristic. 



Macroscytalus laticollis, Broun. 1308. Man. N.Z. Coleopt., p. 737, 



(Plate XV, fig. 10 ) 



Body moderately shining, dark red, head and thorax somewhat piceous, 

 club nigrescent. 



Rostrum for two-thirds of its length nearly as broad as the head, closely 

 and finely punctured in front, more distinctly behind, and as far as the eyes, 

 and with a linear impression from the middle backwards. There is a slender 

 interocular fovea. Thorax hardly any longer than it is broad, impressed 

 along the middle, most obviously near the base, and with 2 oblique frontal 

 impressions, the surface moderately closely and rather finely punctured. 

 Elytra with indistinctly curvate sides, punctate-striate, interstices with 

 numerous distinct serial punctures. 



Underside plane. Mesosternum not abbreviated. Basal 2 ventral seg- 

 ments broadly impressed, and equalling the metasternum in . length ; the 

 latter finely grooved. Coxae small, widely separated. 



S . Length, IJ lines ; breadth, f line. 



Parua, Whangarei. One of each sex. 



M. depressus, Broun. 1433. Man. N.Z. Coleopt., p. 807. 



Shining, castaneo-rufous, the interocular area, front of thorax, and the 

 club somewhat piceous. 



Rostrum finely punctured and shining. Interocular fovea small. Thorax 

 with a shallow median impression at the base only. Elytra broadly im- 

 pressed before the middle. Club much longer than the funiculus. 



S . Length, 1| lines ; breadth, j line. 



Parua. Unique.
