not the finely sculptured transverse striae of that species, and the lateral 

 tubercles are not pointed. The elytra are depressed, coarsely and sparsely 

 punctured, with a raised fiexuous dorsal costa; their colour is brassy green, 

 especially visible on the base and sides, the middle of the back being tawny 

 with an oblique dusky belt^ sometimes absent. The antennsG are much longer 

 than the body, but of the same form and proportions as in H. crista^ the cilia 

 only being longer j they are dull reddish, varied with dusky. 



Hyholasius simplex, n. sp. 



H. gracilior, piceo-rufescens, sparsim griseo-pubescens ; elytris subconfertim 

 punctatis, haud costatis, cristis basalibus fere obsoletis, parum convexis, haud 

 penicillatis ; thorace angustiore, fere nudo, subtilissime et confertissime 

 punctulato-rugoso, tuberculis lateralibus conicis. Long. 2J lin. 



Auckland {Mr. Lawson) ; three examples. 



Much more slender than H. crista, and less convex ; distinguished also by 

 the absence of penicillated crests, which are replaced by obtuse elevations. The 

 general colour is pitchy or chestnut red, lighter on tbe antennae, and darker on 

 the undersides of the body and femora and at the apices of the tibiae j the 

 thorax is minutely sculptured throughout, and has rudiments of three small 

 discoidal tubercles ; the pubescence is very scant ; the antennae have the same 

 form and proportions as in H. crista j and there can be little doubt of the near 

 affinity of these two extreme species, notwithstanding the great difference in 

 the elytral crests. 



PcECiLiPPE, nov. gen. 



Gen. Nicippce et Disternce prima facie simile, sed antennis basi haud 

 approximatis, acetabulis intermediis fere clausis et elytris apice rotundatis. 

 Caput ut in gen. Hyholasio, inter antennas concavum, fronte quadrata. 

 Ante7incB corpore longiores, graciles, ciliatae ; articulo prime quam tertio multo 

 breviore, clavato, basi extus magis angustato, tertio et quarto caeteris singulis 

 multo longioribus. Thorax brevis, antice et postice transversim fortiter 

 impressus,- medio utrinque tuberculo forti acuto armatus. Elytra elongato- 

 subtrigona, modice convexa, tubere utrinque basali elevate. Pro- et mesosterna 

 inter coxas angusta. Acetabula antica extus angulata, intermedia fere clausa. 

 Femora clavata j tibiae intermediae extus perparum emarginatae ; tarsi breves, 

 articulo prime omnium breviter triangulari. Ungues divaricati. 



Although resembling the Australian Disternce in general appearance, this 

 genus differs much from them in structural characters and approaches much 

 more nearly Hyholasius, the form of the scape of the antennae being very 

 nearly the same. The thorax, however, is much shorter, and has a far larger 

 and more acute median spine. The apical ventral segment is much elongated 

 and broadish at the apex in my single specimen ; but I suspect this is a
