clothing somewhat dilTerent. The type has both antennae damaged, but the 

 three basal joints of each are exactly as on undatum. It is a somewhat shining 

 species. From some directions each elytral puncture appears to be in the centre 

 of a small square, but from most directions only the punctures themselves are 

 distinct.

]\Ialc. Bk'.ck, shining. Sides, uiider-surface anfl legs more or less sparsely 

 clothed. 



Head excavated in front, a conspicuous semi-double projection on forehead 

 overhanging the excavation ; punctures large and round, smaller in middle than 

 elsewhere, becoming confluent on sides. Mandibles strongly curved and simple 

 in front, towards base with a large cuspidate mass, Labrum small, subtriangular 

 and subvertical. Antennae with seventh joint slightly wider than sixth, but of 

 the same shape, the three following considerably wider, tenth widely rounded at 

 a]iex. Prothorax almost twice as wide as long, sides feebly serrated, basal angles 

 rounded ofl:", with a wide and shallow dejiression along middle: with round .-ind 

 sharply-defined jjunctures, somewhat irregularly distributed. Sciitclluin very 

 short. Elytra slightly narrower than jirolhorax. each shoulder with a small 

 subdentiform elevation : with fairly large punctures near suture, becoming 

 smaller and crowded about sides and apex ; with a few irregularly distributed 

 scratches, and with a few feeble elevations on which the punctures are sparser 

 than on the adjacent surface. Front tibiae with from -ix to thirteen teeth, of 

 which two are large and from three to five moderately large. Length, 14-16 mm. 



Female. Differs in having the head smaller, with denser punctures, without a 

 median excavation or projection, mandibles much .smaller and otherwise different ; 

 prothorax smaller, sides more conspicuously serrated and narrower across apex, 

 and with more crowded punctures.

The mandibles of the male, although difl'ering in detail, are nearer to those 

 of the Tasmanian eurvicornis than to those of any other species known to me, 

 1inl in other respects the_ species is strikingly ditTerent from that one, and the 

 conspicuous projection on the forehead, somewhat suggestive of that on the 

 forehead of the much larger and otherwise different Lissaptents lum'ittaiiii.s-. will
