416 Major T. Broun on new 



"When compared with P. mucronatus (1468), P. oxymelus 

 appears to have stouter legs, the mandibles arc evidently 

 obliquely striate ; the eyes are more convex and prominent, 

 hut their orbits are less swollen ; the elytral stria? are more 

 regular and less interrupted, the shoulders are not at all 

 prominent, the posterior contraction is less abrupt and deep; 

 the apical spines of the four hind tibise are directed back- 

 wards instead of forwards, as they are in P. mucronatus ; the 

 basal three joints of the front tarsi are less expanded and the 

 second and third are foveate above near the base. 



There are four setigerous punctures on each side of the 

 thorax, but only one at each side of the middle at the extre- 

 mity of the terminal ventral segment. 



$. Length 7^; breadth 2£ lines. 



Manawatu Gorge. One, found by Mr. "W. W. Smith. 



Pterostichus sinuiventris, sp. n. 



Intense black, glossy ; the palpi, tarsi, and basal four joints 

 of antennae rufo-piceous, tips of palpi fulvescent. 



Head almost smooth, with elongate frontal foveas; man- 

 dibles obliquely striate; labrum obliquely emarginate. Eyes 

 convex and prominent, their orbits not swollen. Thorax 

 one-seventh broader than long, widest before the middle, 

 gently rounded, moderately sinuate-angustate behind, poste- 

 rior angles rectangular and slightly projecting ; apex widely, 

 the base medially, incurved; basal fossa? large and elongate, 

 central furrow broad and deep but not reaching the apex. 

 Scutellum deeply striate at base. Elytra oblong-oval, 

 humeral angles slightly projecting, posterior sinuosities 

 rather deep and abrupt, the apex, however, rather broad and 

 obtusely rounded ; they are rather deep and finely punctate, 

 regular, but becoming confused near the extremity ; inter- 

 stices smooth and moderately convex. 



Legs stout, femora dilated ; posterior tibiae slightly flexuous, 

 not prolonged at the inner extremity. 



Female. — Terminal ventral segment near each side of the 

 apex obliquely truncate towards the middle, which is augu- 

 late and somewhat prominent, the whole apex distinctly 

 margined and with a fine groove parallel with the margin, 

 and bearing two setigerous punctures near each side, as in the 

 male. Flanks of the sternum finely punctate or rugose. 

 The head and thorax more or less finely transversely striate. 



Similar to P. oxymelus, but lacking the essential character 

 of that species, i. e. the acute prolongation of the posterior 

 tibia?. The elytral stria? deeper and regular. The thorax
