elytris cristis basalibus parvis vix penicillatis, costa marginali 

 altera fiexuosa dorsali obtusis. Long. 2^-2| lin. 



Auckland (Mr. Lawson). 



Distinguishable from H. crista at once by the small basal 

 crests of the elytra, which have a minute pencil of hairs, some- 

 times absent ; the thorax has not the finely sculptured trans- 

 verse strias of that species, and the lateral tubercles are not 

 pointed. The elytra are depressed, coarsely and sparsely 

 punctured, with a raised flexuous 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 antennas are much longer than the 

 body, but of the same form and proportions as in //. crista, 

 the cilia only being longer ; they are dull reddish, varied 

 with dusky. 



Hybrlasius simplex, n. sp. 



H. graeilior, piceo-rufescens, sparsim griseo-pubescens ; elytris sub- 

 confertim punctatis, haud costatis, cristis basalibus fere obsoletis, 

 parum convexis, haud penicillatis ; thorace angustiore, fere nudo, 

 subtilissime et confcrtissimc punctulato-rugoso, tuberculis latera- 

 libus conicis. Long. 2| lin. 



Auckland (Mr. Lawson) ; three examples. 



Much more slender than H. crista, and less convex ; di- 

 stinguished also by the absence of penicillated crests, which 

 are replaced by obtuse elevations. The general colour is 

 pitchy or chestnut- red, lighter on the antennas, and darker on 

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

 the tibiae ; the thorax is minutely sculptured throughout, and 

 has rudiments of three small discoidal tubercles ; the pu- 

 bescence is very scant ; the antennas have the same form 

 and proportions as in H. crista ; and there can be little doubt 

 of the near affinity of these two extreme species, notwith- 

 standing the great difference in the elytral crests. 



Pcecilippe, nov. gen. 



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

 approximatis, acetabulis intermediis fere clausis et elytris apice 

 rotundatis. Caput ut in gen. Hybolasio, inter antennas con- 

 cavum, fronte quadrata. Antennce corpore longiores, graciles, 

 ciliatas ; articulo primo quam tertio multo breviore, clavato, 

 basi extus magis angustato, tertio et quarto casteris 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 elevato. Pro- et mesosterna inter coxas angusta. Ace-
