182 Tranmction^. 



ventral segment broadly impressed, 2nd shorter, their suture undulate, 

 the 5th with elongate pubescence. 



The rostrum is broader, the eyes more prominent, and the antennae 

 shorter and stouter than in the preceding two species. The scutellum is 

 sunken, and does not seem to penetrate between the elytra. 



The description is given in detail in case the discovery of more specimens 

 should make it expedient to treat this species as the representative of a 

 distinct genus. There can be no doubt as to its being a male.

Parua Forest, Whangarei. Unicjue. 



Agastegnus, Broun. Man. N.Z. Coleopt., p. 805. 



Body slender, pubescence conspicuous. 



Rostrum rather shorter than thorax, somewhat arched, moderately 

 stout, rather gradually narrowed towards the base. Head globose below, 

 curvedly narrowed anteriorly, the contour not interrupted by the sub- 

 depressed eyes, the usually dark colour, and punctuation also tend to render 

 the eyes inconspicuous ; the occiput is short, and not at all distinctly 

 marked off in front. Antennse elongate. Scape slender, gradually thickened, 

 curvate or flexuous, inserted before the middle, in the female at the middle, 

 and attaining the back of the eye. Funiculus laxly articulated, 2nd joint 

 sometimes nearly as long as the basal one, 3-5 submoniliform. Club mode- 

 rately large, subovate. Thorax triangularly ovate, moderately constricted 

 in front. Scutellum small. Elytra broader than the base of the thorax, 

 parallel or gently narrowed backwards, apices slightly rounded individually. 

 Legs elongate and slender ; tarsi narrow, 3rd joint not perceptibly lobed, 

 terminal longer than the basal 3 conjointly, with small claws. 



Prosternum deeply incurved in front. Metasternum longer than the 

 basal 2 segments. 



From Pentarthrum, Ehinanisus, and cognate forms this genus is differenti- 

 ated by the conspicuous vestiture, long slender legs, &c., and from Serico- 

 trogus by the form of the head and more widely separated anterior 

 coxae, &c. 



Agastegnus ruficollis, Broun. 1432. Man. N.Z. Coleopt., p. 806. 



Variegate, moderately shining, pubescence slender, decumbent, yellow, 

 distinct ; rostrum and thorax rufescent ; the head, club, and parts of elytra 

 piceous ; tibiae more rufescent than the pitchy femora ; antennse pale 

 red. 



Rostrum moderately punctured, more finely and less closely in front. 

 Thorax rather longer than broad, widest behind the middle, where it is 

 rounded, more but gradually narrowed anteriorly than at the base, 

 slightly constricted in front ; disc broadly impressed along the middle, 

 moderately coarsely punctured almost to the apex. Elytra rather broader 

 than the thorax, feebly broadly impressed before the middle, with rather 

 shallow but distinctly punctured striae, interstices with minute serial 

 punctures, the 2nd beyond the suture distinctly elevated and bent out- 

 wards near the apex. 



Female. — Rostrum slightly more slender, parallel, less arched above. 

 Thorax rather narrower, less constricted in front, its disc unimpressed.
