2 68 COLEOPTERA 



nearly nude and punctate ; the three basal joints of the autentice are of 

 the usual form, the remaining five are pubescent and form the club. 

 The preceding and the present species are allied, of a velvet-like aspect. 



471. O. sylvatica, «.x. This species is intermediate between the 

 preceding and following species, moderately convex, rather narrow and 

 shining, having nothing of the dull velvety aspect observable in O. 

 striata and allied forms, yet distinct enough from the two ( O. rossii 

 and stib-caritiata) whose description follow. 



The head is coarsely but not closely punctured with a smooth space 

 behind, piceous in colour, but \\nth the clypeus reddish, and sub-truncate 

 in front. The//-^///^;'^a- has the apical and dorsal spaces smooth, but 

 the rest of the surface punctate, and sparingly clothed with short yellow- 

 ish hairs. Sciitelhan punctate and pilose. The elyti-a are moderately 

 distended behind, each bears nine striae, and their whole surface is more 

 or less but not closely punctured, and their pubescence is scanty and 

 rather shorter and paler than that of the thorax ; their colour resembles 

 that of the thorax, a variable castaneous, some parts darker than others, 

 the prevailing hue however being reddish. 



The imder-surface is punctured, the meso- and metasterna rather 

 closely, it is more or less pilose, and of a duller testaceous colour than 

 the legs. The anten7i<z have their three basal joints of the normal form, 

 the fourth is stout and a little produced, the fifth is quite half as long as 

 the sixth, so that the club may be said to be four-jointed. 



Length, 5 J \ breadth, 25 lines. 



I found one example at Whangarei Heads, and I am indebted to 

 Mr. Hugh Munro, of Marsden Point, for a second. 



472. O. rossii, Jlliite ; Voy. Er. Terr., Ins., p. 10. Clypeus 

 yellow ; head in front and spot on vertex yellow, space before and to the 

 side of the eyes deep brown ; thorax yellow, with three longitudinal 

 lines in the middle not touching the front margin, the middle straight 

 and narrow, the side-lines wider and somewhat waved ; elytra yellow, 

 A\-ith widish deep-bro^\'n reticulations ; head and thorax with irregular 

 punctures ; elytra with at least nine rows of longitudinal strise ; legs and 

 under-side pale-yellow. 



Length, 3^ lines. 



New Zealand (Kaudi). 



Note. — I found a specimen of what I believe to be the male of this 

 species at Parua, near Whangarei Harbour. It measures ■t^\ lines in 

 length by if in breadth. The prothorax is transversal, but not very 

 much so, the sides are a little angulated near the middle, a good deal 

 narrowed in front with acute angles nearly reaching the middle of the 

 eyes, and nearly straight behind, its apex being emarginated at each side 

 of the middle. The elytra are not much dilated, and are slightly nar- 

 rowed towards the apex ; the rows of punctures are tolerably regular, 

 but the striae are not very well defined, and the dark spots are slightly 

 raised. The clypeus is almost rounded in front, its outline neither 

 truncate nor regularly-rounded, but just intermediate between the two
