410 Major T. Broun on new 



fossse rather longer than broad and situate nearer the sides 

 than to the middle; there is a feeble curvate frontal impres- 

 sion. Scutellum slightly striate at base. Elytra a little 

 longer than the head and thorax combined, suboblong, rather 

 wider behind than at the base, where they barely exceed the 

 thorax in breadth ; humeral angles obtusely dentiform, poste- 

 rior sinuosities oblique but not deep, apices quite obtusely 

 rounded, lateral margins well developed ; the dorsum flat ; 

 each elytron with eight very finely punctured striae ; inter- 

 stices moderately broad, the third and fifth with five or six, 

 the seventh with eight or nine conspicuous punctures, the 

 sides with coarse serial punctures. 



Legs moderately long, thick, femora dilated. 



Male. — Tarsi: anterior with the basal three joints strongly 

 dilated and cordiform, with grey spongy squama;, and fringed 

 with ferruginous seta? underneath ; their fourth joint also 

 cordate ; the posterior rather short, basal articulation rather 

 longer than second, the basal four intermediate between cordate 

 and triangular, the terminal somewhat thickened towards the 

 extremity. 



Female. — Labrum so much abbreviated that its punctured 

 apex only is visible, so that the tropin are quite exposed 

 between the open mandibles. Front tarsi with subcordate 

 intermediate joints, the basal and terminal of nearly equal 

 length. ISize 8x2^ lines. 



Mentum tooth bifid. Basal ventral segment almost wholly 

 concealed. Both sexes with two setigerous punctures on 

 each side of the middle, at the extremity, of the last ventral 

 segment. 



$ . Length 9^ ; breadth 2f lines. 



Manawatu Gorge. One of each sex, discovered on different 

 occasions, by Mr. W. W. Smith. 



Obs. — Certainly a very curious species. The structure 

 quite Pterostichoid. The legs are thick, like those of an 

 African Anthia. The thorax of the female resembles that of 

 a North-American Holciophorus in shape. The elytra are 

 somewhat like an Australian Ilomalosoma. The swelled head 

 is considered a colonial characteristic and is like that of our 

 Trichosternus planiusculus. 



Pterostichus odontellus, sp. n. 



Elongate-oblong, moderately convex, brilliant and intensely 

 black; legs piceous ; tarsi, antenna?, and labrum piceo- 

 rufous, palpi paler. 



Head nearly as wide as thorax, the forehead a little uneven
