the front, subparallel behind; its basal angles finely carinate above and 

 directed backwards, the anterior prominent but obtuse; the surface 

 moderately closely and rather finely punctate, still more finely near the 

 base; there is no median impression. Elytra thrice the length of the 

 thorax, a little wider near the hind thighs than at the shoulders, their 

 apices emarginate and minutely angulate; they are finely punctate- 

 striate, with minutely sculptured interstices. 



Underside fulvescent, very finely clothed and punctured, the sternal 

 structure similar to that of C. antipodum . 



Antennae filiform, attaining the base of the thorax, their 2nd joint 

 quite half the length of 3rd. 



It may be readily identified by being more brightly coloured than any 

 New Zealand member of the genus. C. antipodum (532) is its nearest 

 ally, but the punctate elytral striae and the differently formed and less 

 densely sculptured thorax are distinctive.

3241. Corymbites vitticollis sp: nov. 



Elongate, slightly nitid, fuscous ; the elytra with a broad streak along 

 the middle of each, and the suture somewhat rufescent; the thorax with 

 a more definite and rather broad reddish median streak, its sides paler ; 

 legs and antennae testaceous; the clothing flavescent, rather dense, and 

 coarser on the head and labrum than it is on the elytra. 



Thorax moderately convex, about a fifth longer than broad, in the 

 middle, posterior angles indistinctly carinate and almost quite straight, 

 its surface closely and moderately finely punctate. Elytra rather finely 

 sulcate, the sutural pair of striae impunctate, the punctation of the 

 others becoming coarser towards the sides, interstices closely and very 

 finely punctured, the apices simple. 



Underside pale castaneous, but with the Hanks of the presternum 

 testaceous and very distinctly punctured, metasternum medially sulcate, 

 abdomen finely and closely punctate; with fine greyish-yellow pubescence. 



Antennae short, not attaining the base of thorax, their 2nd joint only 

 a little shorter than the 3rd, which is rather shorter than the 4th. Tarsi 

 elongate, their penultimate joint but little more than half the length of 

 the 3rd. 



Distinguishable from G. strangulatus by its coloration, simple and 

 less divergent thoracic posterior angles, differentry formed antennae, &c. 



Length, 13 mm.; breadth, 3| mm.

3242. Corymbites approximans sp. nov. 



Elongate, a little shining, castaneo-rufous, the legs and basal two 

 joints of antennae testaceous, remaining joints infuscate; pubescence 

 yellowish-grey. 



Thorax closely and moderately finely punctate in the middle, about a 

 fifth longer than broad, with slightly divergent and finely carinate pos- 

 terior angles. Elytra with narrow impuncate striae, interstices closely 

 and finely punctured, apices simple. 



Underside rufo-fuscous, densely and finely punctate and pubescent, 

 metasternum medially sulcate.
