the eyes, which are somewhat emarginate on their inner edge. Head, 

 when extended, with its posterior part laid on the apex of the thorax. 

 Mandibles visible from the front ; labrum small but visible between the 

 mandibles ; maxilla and labium placed in a cavity on the under-side of 

 the head, this cavity is well denned by a margin which forms a curve 

 extending between the front angles of the head ; the labium is appar- 

 ently excessively reduced, and I cannot see any mentum or labial palpi ; 

 the maxillae are exposed ; their palpi are not very large and are four- 

 jointed, the basal joint being, however, very minute, the second joint is 

 longer than the third, and the fourth about as long as the second and 

 third together, and oval in form. Thorax much narrowed in front, its 

 anterior' opening looking downwards, prosternum separated from the 

 flanks of the pronotum by an obscure suture ; front coxa much exserted, 

 sub -cylindrical and perpendicular, their cavities widely open behind, but 

 placed at a considerable distance from the front edge of the prosternum. 

 Mesosternum rather large, with a prominence in the middle which fits 

 between the front coxae ; the middle coxae separated by a prolongation 

 of the mesosternum, which extends as far as the hind part of the coxae, 

 and has there a free slender extremity. Metasternum elongate, its 

 episterna very large, its epimera not visible. Hind coxae large, but only 

 about half as long as the metasternum. Hind-body slender, of five 

 visible ventral segments, the first of which is about as long as the apical 

 one, the three intermediate being moderately long and about equal to 

 one another. Legs elongate and very slender, the tibia without spurs, 

 the tarsi longer than the tibiae, the front and middle ones five-jointed, 

 the hind ones four-jointed. The claws have been covered with gum 

 tragacanth, so that I cannot see their structure.

The first joint of the antenna is longer and rather thicker than the 

 second ; the third is longer than the first, but similar to it in form ; the 

 fourth joint is stout, quite as long as broad ; the other seven joints very 

 short, but each giving off an appendage, and of these the first four or 

 five are each as long as the three basal joints. 



I have received a mutilated individual of this species from Captain 

 Broun, and am informed that he has found only two individuals, at 

 Tairua.

Nov. gen. 



Antenna eleven-jointed, inserted at the sides just in front of the eyes, 

 robust, nearly as long as the head and thorax, the basal joint stout, 

 dilated towards the apex, second rather small, oblong, third a little 

 shorter than first, obconical^ fourth subquadrate, a little larger than
