eight to ten piiliquiidratc ; eleventh elougate-oval ; tlic basal 

 three articulatiuns are less pubescent than the following 

 ones. My fi male speeimen, owing to malfui raation, (litters 

 considoraljly in antonnal structure. 



Vvdcrsidc, incbuling the fiinora, shining pitchy-black, 

 mo'lerati'ly closely pnnctun d, the inctastcrnuni most coarsely. 

 Flanks of jirosternnm smooth, the intcrcoxal process broad, 

 but not ])r(ilongcd and fitting into the diep angular nicso- 

 stcrnal ea\ity. The jjostcrior leniora arc accomniodatcd in 

 rather large deep cavities. The abdominal sutures are nearly 

 fctraight, the fourth only being somewhat incurved.

Named in lujuour of Mr. J. II. Lewis, who found tliis 

 fine species uniler stones near a stream on the Old Man 

 Kiingc, Otago, at au elevation of 4100 feet. It may be 

 easily recognized by its rather large size and more or less 

 obvious clvtral striae. 



Group MelolonthidoB. 

 Scythrodes squalidus. 



This new genus and species of our Southern Alps was 

 founded (Man. N.Z. Coleopt. p. 955) on a single female 

 discovered by Mr. G. M. Thomson, about twelve years ago, 

 at an elevation of GOOO feet on Mount Tyndall. Quite 

 recently, ]Mr. J. II. Lewis kindly scut me some males which 

 he hiid found on Obelisk Peak, Ciirrick Kangc, at an elevation 

 of -1 100 feet. These males exhibit several discrepancies of 

 sculpture and antenual structure when carefully compared 

 vith the typical female, so it Avas considered best to draw up 

 the sul joined dtscri})tion so that others may not make the 

 mistake of treating the sexual forms as distinct sjiccics. 



lioihj broadly oviform, only moderately convex, nigrescent, 

 nearly nude. 



(J . Antenna rather short, without pubescence. The basal 

 joint ecjuals the following four conjointly in length, but the 

 portion visible from above barely exceeds the second in 

 leiigih, it is gradually thickened towards the oblique ap( x, 

 which bears three or four elongate setie ; second nearly twice 

 as long as ])road, somewhat pyriturm, but unsymnutriial, 

 the inner si'ile being straight whilst the outer is swollen; 

 third subtriangular, obviou^ly smaller than the contigm us 

 ones ; fourth triangularly cordiform, about twice the breadth 

 of the preceding one; fifth remarkably short, as wide as the
