OF NEW ZEALAND. 195 



transversely convex, sides slightly explanated, and not very perceptibly 

 serrate ; front angles prominent, the base obliquely rounded ; its surface 

 is finely granulated ; the disc is rather uneven, with a dorsal depression, 

 and some irregularly formed costse and intervening depressions, none of 

 which, however, are very well defined. The elytra are oblong, trans- 

 versely convex, and about as wide as the thorax ; each bears eight rows 

 of punctures, which are arranged in duplicate ; the interstices between 

 the first and second, third and fourth, and fifth and sixth, are narrow, 

 and are finely hispid, with griseous hair-like setae ; the alternate inter- 

 stices are much broader, dull black, and bear from four to six rounded 

 patches of short white pubescence ; margins hispid. The legs are 

 piceous, and finely hispid.

Of this distinctly-marked species, I found only one specimen at 

 Tairua. The form is evidently abnormal ; but it does not exhibit any 

 prominent structural characters which would exclude it from association 

 with the immediately preceding species. It should precede B. rugosa 

 in the list. 



349. B. diSCOidea, n.s. Body obscure red, densely clothed with 

 minute yellowish-grey scales; antenna piceous (in one example fuscous), 

 with the basal joint clear red ; club distinct, the tenth joint transverse, 

 almost cup-shaped, the eleventh rounded. Head with two rather large, 

 not very deep, almost confluent depressions in front ; its sculpture is 

 evidently fine, but almost entirely concealed by the clothing. The 

 thorax is about as long as it is broad, in front as wide as the elytra, and 

 narrowed posteriorly ; its apex is outwardly curved ^at the middle, and 

 emarginated behind the eyes, but the front angles *are not porrected, 

 and rather obtuse ; the disc is transversely convex, so that the sides 

 appear dilated, and ragged, but not at all lobed as in Ulonotus, or dis- 

 tinctly serrate ; the base is rounded towards the sub-acute hind angles ; 

 the disc is uneven, with curved and angular lines and intervening 

 depressions, the depressed parts and sides are, apparently, very finely 

 granulated. The elytra are oblong, with a somewhat flattened disc, and 

 compressed sides ; the space from the base to the posterior declivity, is 

 covered with minute yellowish-grey scales, and this discoidal portion 

 bears twelve striae, which seem to be punctured ; two basal, elongate 

 elevations, near the middle, and one at each shoulder, but none of them 

 greatly elevated ; and six small tubercular elevations behind ; the scutel- 

 lar region is depressed ; the sides are piceous, the apex infuscate. The 

 legs are infuscate-red, and finely setose. 



Length, nearly i J line. 



I found two specimens at VVhangarei Heads ; in one, the elytra are 

 not so distinctly marked as in the more perfect specimen. The species 

 should be placed after B. nana.
