Species q/Tselapliidje/ro/H New Zedland. 701 



the exposed portion of the basal joint only about half as long 

 as it is broad ; second and third joints obconical, hardly 

 longer than broad ; joints 4-8 differ but little, all broader 

 than long, ninth and tenth a little larger, eleventh conical 

 and subacuminate, longer than the penultimate. 



First ventral segment short and covered by the femora, the 

 next unevenly convex in tlie middle, tliird quite as long as 

 the second, with a basal depression at each side of the middle ; 

 fourth and fifth short, the latter widely but not deeply in- 

 curved behind ; sixth with a deep, semicircular, apical 

 eniargination, which is occupied by the flat, broadly oval, 

 supplementary segment. 



Female. — Second and third ventral segments nearly equal, 

 fourth and fifth much shorter, sixth large, obtusely triangular. 



A written copy of the description of the male and a speci- 

 men of the female have been forwarded to M. Ach. Raflfray. 

 He kindly informs me that this exceedingly curious new 

 genus belongs to a new and very isolated section of the 

 Euplectini. 



3387. Kenoccelus dimorphus, sp. n. 



Shining, rufescent, tarsi and palpi yellow, terminal joint 

 of antennse fulvescent; sparingly clothed with decumbent 

 greyish pubescence. 



Head quadrate, slightly flattened and quite obsoletely 

 bifoveolate in front, very finely and distantly punctate, with 

 a pair of small, distant, interocular fovese. Eyes moderately 

 large and prominent, situated behind the middle. Thorax 

 nearly twice as long as broad, widest and somewhat rounded 

 just before the middle, slightly sinuate behind, very finely 

 and distantly punctate, with a slight antebasal impression 

 connecting the rather shallow lateral fovea and the sulciform 

 median depression. Elytra longer and broader than the 

 thorax, a little narrowed towards the base, finely punctate, 

 with rather fine sutural stria?, the intra-humeral impressions 

 lather short and shallow. 



Female. — Eyes very small and indistinct. The body less 

 nitid and darker, elytra more rounded at the sides and 

 narrower at the base, and the hind body more horizontal and 

 therefore apparently longer.
