266 COLEOPTERA 



mixed ; elytra yellowish-brown, with nine rows of blackish punctured 

 lines and a few blackish spots placed irregularly between some of these 

 rows, a few longish scattered hairs on the upper surface ; under parts of 

 thorax covered with soft yellowish hairs ; iDider-side of abdomen yellow, 

 varied with black ; legs yellow, with some blackish hairs and spines on 

 tibiae ; tarsi blackish. 



Length, i\ lines. 



Otago ; sides of hills on flowers. 



Note. — This is the largest, most robust, and convex form. The 

 elytral interstices are punctulated, the punctation of the prothorax is 

 concealed by its clothing. The basal joint of the antennce is long and 

 clavate at apex, the second short, third elongate and slender, the fourth 

 and fifth are strongly produced, the latter as long as the sixth, the former 

 a little shorter, so that the club appears to be five-jointed and dull, the 

 other joints being shining. 



My specimen was sent me from Otago, by Professor Hutton. It 

 measures 7 lines in length by ^\ in breadth. 



467. O- SUaviS, n.s. Allied to O. striata, of similar robust form. 

 Head reddish-piceous, the clypeus coarsely and rugosely, the rest rather 

 distantly punctured. The prothorax is of a pale-reddish colour, and of 

 a rather velvety appearance, is punctulated, with short yellowish hairs 

 proceeding from the punctures, and bearing a few long ferruginous 

 hairs, the clothing, however, is not at all dense. Scittellum large, punc- 

 tate, and pilose at the base. The elytra are rather convex, of the same 

 velvety appearance and colour as the thorax, but a trifle more obscure ; 

 each has nine rather broad costne, which are very finely punctured, the 

 intervening stri^ are punctulated and duller than the elevated portions ; 

 their clothing consists of short yellowish hairs. 



The abdomen is brownish-testaceous, the two basal segments have 

 elongate impressions, the others punctures, it is finely pilose. The legs 

 are testaceous, the tarsi almost ferruginous. 



The species is quite as convex and rather narrower than O. striata, 

 with the elytra less dilated posteriorly. 



The antennce have the basal joint of the usual form, long, slender at 

 base, and incrassated towards the apex; the second short; third slender, 

 about as long as the obconical fourth joint ; fifth short, a little produced 

 inwardly ; the club rather short. 



I have one example only, which was given to me by Mr. J. Buchanan, 

 F.L.S., of Wellington. 



Length, 6i ; breadth, 35 lines. 



Obs. — When compared with O. striata it will be seen that the thorax 

 is far more sparingly punctured, the elytra more carinated, and the 

 surface much more finely and sparingly pilose ; the clypeus, as in 

 O. striata, is widely rounded, forming an almost uninterrupted curve 

 from eye to eye, and its margins are raised. 



468. O. puiictulata, n.s. Robust, of a uniform very dark brown, 

 almost black colour, above ; under-side pale brown and punctulate, the 

 breast pilose ; the femora are pallid and punctate, tibiae and tarsi darker.
