336 Major T, Broun on new 



rendered dull by minute sculpture and transverse aciculate 

 marks. 



Underside moderately shining; head with short, dense, 

 undulating sculpture ; the prosternum rather finely and 

 distantly punctate, its flanks more closely and distinctly, 

 intercoxal process broadly grooved ; the metasternum and 

 basal ventral segment at the sides finely and distinctly punc- 

 tured, remaining segments with irregular linear impressions 

 and indistinct punctures ; the terminal at the apex bears two 

 setigerous punctures at each side of the middle. 



Not glossy like M. scitidum, elytral striai more shallow, 

 without punctures on the seventh interstices, quite dififcrently 

 sculptured underneath, and with lateral margins of the thorax 

 crenulate. It difi'ers from all the species with crenulate 

 thoracic margins by the elytral sculpture. 



c?. Length 12; breadth 3| lines. 



Mount Holdsworth, Tararua Range, in the birch-forest at 

 an elevation of 1500 to 2000 feet. 



Described from one example forwarded by Mr. G. V. 

 Hudson. 



Mecodema cognahim, sp. n. 



Body moderately elongate, glossy black, the antenna*, 

 legs, palpi, and labrum pitchy red. 



Head (eyes included) nearly as wide as thorax, almost 

 smooth, having only some longitudinal rugas in front and 

 near the eyes ; there is one setigerous puncture near each of 

 these. Mandibles wrinkled. Antennw pubescent from the 

 fifth joint onwards. Thorax d-3^ lines broad by 2^ in length, 

 slightly incurved in front and at the base, its greatest width 

 near the front, gradually curvedly narrowed backwards, 

 without any abrupt contraction near the obtuse basal angles ; 

 lateral channels rather narrow, of about equal width through- 

 out until approaching the basal foveas, which are close to the 

 sides ; these bear eight or nine setigerous punctures, but are 

 not crenate ; disk but little convex, with a well-marked 

 central furrow, an indefinite curvate impression from one 

 anterior angle to the other, and some short feeble longitudinal 

 impressions near the base and apex, but no very evident 

 transversal rugse anywhere. Elytra elongate, oviform, the 

 shoulders and extremity of about equal width ; they are 

 distinctly punctate-striate, the four sutural strite rather fine, 

 with flat interstices ; those beyond, however, are deeper, with 

 stronger yet only moderate ))unctures and distinctly convex 

 intcrsiiccs ; the connnon smooth space along each side is more
