sides explanate ; disc convex, uneven, with two abbreviated frontal 

 costee (oblique). Scutellum invisible. Elytra connate, scarcely wider 

 than thorax, slightly curved laterally, deflexed behind ; each has 

 two sinuous costae, the outer hardly reaching the base and forming 

 the external border of the dorsum, the sides, however, are expanded 

 beyond ; the intervals are impressed with rows of coarse, shallow 

 impressions. Tibia finely ciliated, the posterior slender at- base, 

 expanded beyond, and again contracted apically ; tarsi elongate. 



Length, f line ; breadth, nearly f . 



I found three specimens near Howick, on the ground, amongst 

 decaying vegetable matter ; and I have another which was found by 

 Mr. P. Stewart- Sandager on Mokohinau Island. 



Group-PYCNOMERID^E. 



Pycnomerus (p. 208). 



1714. P. COgnatUS, n.s. Elongate, not parallel, nude, shining^ 

 rufo-piceous, legs and antennae red. 



Head moderately elongate, punctate, the frontal impressions and 

 lateral plicae extending to the occiput. Antenna n -articulate, joints 

 4-9 transversal, tenth large ; eleventh small, appearing like a pubes- 

 cent appendage. Eyes not distinguishable. Thorax oblong, truncate 

 in front, anterior angles sub-depressed and not prominent ; sides 

 margined, a little narrowed posteriorly, with a short, oblique space 

 in front ; base rounded and finely pubescent ; disc moderately bi- 

 irnpressed longitudinally, lateral channels narrow but distinct and 

 prolonged inwardly along the base, with rather large distant punc- 

 tures, less numerous on the middle than elsewhere, and with a row 

 of smaller punctures on the hind margin. Scutellum invisible, or 

 nearly so. Elytra broader than thorax, their sides a little rounded, 

 a good deal narrowed near the apices, humeral angles acute and pro- 

 jecting, base incurved ; deeply striate, the punctures in the striae 

 distant and shallow, and therefore not easily detected, interstices 

 convex, finely punctated, the third bent inwards at the base to unite 

 with the suture ; second, fourth, and sixth not reaching the base. Legs 

 moderate, the tibiae hardly perceptibly produced at the outer ex- 

 tremity, and with minute apical spurs. Underside opaque, coarsely 

 punctate ; metasternuni broadly impressed ; coxae rather distant. 



P. CCBCUS is its nearest congener, but in it the thorax is less un- 

 level and more finely punctured, the humeral angles are less promi- 

 nent, and the punctures in the elytral striae, though rather distant, 

 are quite easily seen.
