6l2 COLEOPTERA 



Distinguishable from H. crista at once by the small basal crests of 

 the elytra, which have a minute pencil of hairs, sometimes absent ; the 

 tliorax has not the finely sculptured transverse strise 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, some- 

 times absent. The anten?tce are much longer than the body, but of the 

 same form and proportions as in H. crista, the cilia only being longer ; 

 they are dull reddish, varied with dusky. 



1075. H. promiSSUS, n.s. Elongate, sub-depressed, piceous. 

 AntenncB hispid, obscure-red, with the basal joint rather elongate ; the 

 third and fourth joints very long, each twice as long as the fifth, which is 

 longer than those which follow. Head closely and coarsely punctured, 

 impressed down the middle ; eyes large and coarsely facetted. Thorax 

 rather short, constricted behind, with obtuse lateral tubercles ; slightly 

 narrowed anteriorly, and a little constricted in front of the lateral tubercles; 

 its surface is uneven, closely punctate, with three small discoidal tubercles 

 disposed in the form of a triangle ; it is almost nude. The elytra are 

 elongate, with obtuse but prominent shoulders ; their sides are nearly 

 straight, the apices divaricate, and rather acute ; each bears an obtuse, 

 laterally compressed tubercle near the base, and an obtuse elongate 

 elevation near the middle, the intervening space being rather depressed ; 

 they are strongly punctured from base to apex, and are clothed with fine 

 short pubescence, the palest being concentrated near the depressed 

 parts, and there are a few white bristles distributed along the sides and 

 behind, the surface bright. Scutelliim broad. The legs are rather long, 

 of an infuscate-red, and bear numerous white bristles and fine pubes- 

 cence. 



Length, 3 lines. 



I found two specimens of this distinct form at Tairua ; the species, 

 I think, is intermediate between H. lanipes and H. viridescens. 



1076. H. simplex, Bates ; Ann. Mag. Nat. Hist, Aug., 1874. 

 H. gracilior, piceo-rufescens, sparsim griseo-pubescensy elytris subcon- 

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

 convexis, haud penicillatis ; thorace angustiore, fere nudo, subtilissime et 

 confertissime punctulato rugoso, tuberculis lateralibus conicis.

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 the 

 antennte, and darker on the under-sides 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 pubescence is 

 very scant ; the antcnnce 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, notwithstanding the great difference in the elytral crests.
