390 Major T. Broun on ncio Genera and 



each elytron, including the suturCj there are three slight 

 ridges, the external one is nodiform on top of the declivity, 

 they are apparently formed of granules ; there are two series 

 of punctures between each two of these and an equal number 

 nearer each side; when looked at in certain ways these serial 

 punctures seem like granules ; the lateral sculpture is ill- 

 defined. 



Antenna with the basal joint oviform rather than cylindric 

 and attached to the head by a slender stalk ; joints 3-5 ob- 

 conical, longer than broad, third slightly longer than the 

 others ; 6-8 small and moniliform, ninth rather larger, trans- 

 verse; tenth abruptly enlarged, transverse; eleventh also 

 large, rotundate, Antennal cavities large, apparently not 

 prolonged below along>ide the eyes. Eyes minute, with 

 coarse facets. Tibm finely setose, the anterior somewhat 

 expanded externally near the middle, but a good deal 

 narrowed or almost notched near the extremity. Mandibles 

 bifid at apex. Mentiim oblong, narrowed anterioily. Pro- 

 sttrnvm widely incurved in front, its fianks flattened but not 

 in the least excavate. Coxcb moderately separated. Meta- 

 sternvm of modeiate length. Epipleura very narrow near 

 the extremity. Abdomen with the basal segment nearly twice 

 as long as the second, which is but little longer than the 

 third or fourth, their sutures broad and deep. 



The thorax is less rounded and prominent at the middle of 

 the apex than in P. riijicornis.

Broken Kiver, Canterbury {Mr. J. H. Lewis). 



Protarphius posticalis, sp. n. 



Body moderately transversely convex, covered with greyish 

 scaly or sappy matter, and bearing fine, short, yellow setae ; 

 it is fuscous, with pitchy-red legs and anteunse. 



Head minutely granulate. Thorax rather large, about a 

 third broader than long, w ith a frontal channel which, on the 

 middle, becomes a large angular depression ; two oviform 

 depressions behind, a large one near each posterior angle, 

 and an oblique transverse one towards each side in front, the 

 intervals more or less obtusely elevated ; its sides curvate, 

 rather thick, and a little expanded; the sculpture indistinct, 

 consisting apparently of shallow punctures. Elytra medially 

 emargiuate at base, slightly broader there than the base of 

 thorax, a good deal curvedly narrowed behind ; at the base 

 there are two moderate elevations, the intervening space 

 being broadly depressed ; in line with these, near the middle.
