species of Netv-Zealand Coleopfera. 343 



tlic middle, moderately curvedlj narrowed anteriorly, with 

 fine distinct margins; the disk a little convex, its median 

 groove distinct but not attaining the apex, basal fossge well- 

 marked and nearly duplicated, and extending inwardly 

 towards the middle, there is an obtuse carina between each 

 and the outer margin, the whole basnl region is distinctly 

 punctured; posterior angles exactly rectangular. ScHtelluin 

 smooth. Elytra broadly oval, with explanate margins, which, 

 however, become indistinct near the extremity ; their sutural 

 two strijB, on each, are well marked and finely punctured, 

 the others are finer and become obsolete near the sides and 

 base, third interstices tripunctate, the posterior carina rather 

 fine. There is a transverse series of four punctures near the 

 extremity of the last ventral segment. 



Readily distinguishable from 0. nigritulus by the quadrate 

 and obviously punctured thorax, much less convex eyes, deep 

 elongate frontal impressions, and from all the other species 

 by the flavesceut antennai with the rather slender basal 

 articulation.

Oopferus sculpiuratus, sp. n. 



Subollouf/, moderately convex, shining, piceous ; the head 

 and the suture and margins of elytra rufo-piceous ; legs in- 

 fuscate red ; the palpi, "tarsi, and basal two joints of antennae 

 nifo-testaceous, remair.ing joints f'usco-rufous. 



Uead (the large but not very prominent eyes included) 

 as broad as front of thorax, ovate ; the frontal impressions 

 though elongate are not well defined, owing to the gradual 

 outward slope of the head, lliorax rather short, about a 

 third broader than it is long, widest near the middle, 

 moderately strongly rounded, rather gradually narrowed 

 behind ; posterior angles straight, not acute, but, nevertheless, 

 appearing slightly prominent, reddish, with a rather coarse 

 setigerous puncture, the seta itself yellow and unusually 

 conspicuous ; base truncate, apex slightly incurved; the dis- 

 coidal sulcus not abbreviated but more slender at the 

 extremities, basal £oss£e large and transverse, disk moderately 

 convex, with feebly impressed indistinct striaa across it. 

 Elytra broadly oval, about a third broader than the thorax in 

 the middle, with well-developed lateral margins and chaimels ; 

 each elytron has a well-niaiked scutellar stria, the sulci 

 nearest the suture are rather deep and relatively rather dis- 

 tinctly ])Ui!Ctured, those near the side become finer, none,
