Genera and Species of New Zealand Cohoptera. G17 



antenna is inserted ; the middle of the forehead smooth, the 

 rest of the surface moderately coarsely punctured. Mandihhs 

 prominent, curvate, tridentate at extremity ; along the inside 

 they bear many outstanding slender fuscous setaj similar to 

 those on the basal joint of the antennae. Eyes but little 

 prominent. Antennce pitchy red, the basal joint slightly 

 curved and nearly as long as the following six taken together, 

 second stout and moniliform, 3-6 short, seventh slightly 

 produced in front ; club with three elongate almost equal 

 joints, each fringed with fine erect pubescence. Thorax 

 transverse, wider behind than in front, its sides rounded ; 

 posterior angles nearly rectangular but not at all projecting, 

 base bisinuate ; its surface moderately coarsely but not closely 

 punctured ; the central longitudinal space, however, is smooth. 

 Elytra oblong, with ill-defined sutural strice, their punctuation 

 like that of the thorax, but closer. 



TibicB sparsely clothed, the anterior slightly curved, their 

 outer edge crenate ; the inner terminal calcar is straight, the 

 external is prominent and curved, near the middle there is 

 the usual dentiform projection ; the middle and hind tibiae 

 are straight, the former have a small median tooth on each, 

 but the posterior are unarmed. 



Underside piceous ; abdomen with fine grey setae, the 

 punctuation coarse and disposed in transverse series ; meta- 

 sternum convex, canaliculate in the middle, its flanks rather 

 coarsely punctured and clothed with elongate greyish scales. 



Allied to M. macrocerus, but the head is much broader, 

 especially in front, and the antennal club is very much shorter. 

 The mandibles most nearly resemble those of Lissotes llelmsi 

 in form.

Group Pycnomeridse. 

 Pycnomerus tiitiventris, sp. n. 



Suhparallel, elongate, nude, opaque, piceous ; legs pitchy 

 red ; antennae darker. 



Head distinctly punctate, more finely in front, the lateral 

 elevations before the eyes well developed, but the intervening 

 impressions are slight. Eyes convex. Thorax one third 

 longer than broad, apex truncate, base slightly rounded, 

 lateral margins narrow ; the sides are nearly straight, but 

 a little narrowed behind and in front; anterior angles 

 rectangular, the posterior not at all prominentj its surface is
