46 Mr. D. Sharp on the Dascillidse of New Zealand. 



opacis, longitudinaliter vix conspicue tricostatis. Long. 8 m. m., 

 lat. ^ m. m. 



Though rather similar to the preceding species, this is 

 distinguished by numerous characters easily perceived : the 

 eyes are more prominent ; the thorax is narrower in proportion 

 to the elytra ; and the punctuation of the elytra is very much 

 finer. 



This species is another of Captain Broun's discoveries at 

 Tairua ; a single specimen each has been received by Mr. 

 Wakefield and myself as no. 5. 



6. Cyphanus debilis, n. sp. 



C. suboblongus, hand latus, dense subtiliter punctatus et pubescens, 

 subopacus, ferrugineus, elytris dilutioribus ; antennis elongatis, 

 articulo basali crasso, tertio elongate quam quartus dimidio bre- 

 viore ; capite sat angusto, mandibuKs sat elongatis, porrectis ; 

 prothorace dense subtihter granuloso-punctato, opaco, brevi, sat 

 lato, angulis anterioribus rotundatis nullo modo prominulis, late- 

 ribus anguste esplanatis, subrectis, angulis posterioribus omnino 

 rotundatis, basi utrinque baud perspicue sinuata ; elytris dense 

 subtiliter punctatis. Long. 6 m. m., lat. 2|- m. m. 



This species in appearance is quite as much allied to the 

 following as it is to the preceding ones ; yet it is with these 

 that its structural characters associate it. The specimens I 

 have seen are in extremely bad condition. 



This species has been sent from Tairua by Captain Broun 

 as no. 8. 



Group 3 is formed by species nos. 3, 4, 5, and 6, which 

 possess the following characters : — 



Form rather elongate and narrow, size moderate. Antennas 

 elongate. Head short and broad, the interantennal portion 

 not extended forwards ; the antennal fossae very profound, and 

 at their termination very distinctly separating the gense from 

 the extreme basal portion of the maxilla ; mandibles large, 

 moderately prominent ; labrum exposed, separated by a short 

 membranous space from the front of the head ; labial palpi 

 strongly furcate ; i.e. the 2nd joint is so formed that it appears 

 to be the terminal one, the 3rd joint being inserted on the 

 basal portion of its inner side. Front band of prosternum 

 excessively reduced ; prosternal process hastate in form, pro- 

 jecting much further backwards than the coxge, its junction in 

 front with the middle piece of the sternum is on a level with 

 the tips of the coxse. Coxal articulation between meso- and 

 metasternum good.
