OF NEW ZEALAND. 761 



Long., 10 mm. ; lat., 4! mm. 



Antenna with the five basal joints piceo-riifous, slender, and 

 shining, the apical five abruptly broader than the others, fuscous- 

 black, densely pubescent and opaque. Head closely and finely 

 punctured, even in front ; the clypeal suture indistinct, angulate 

 in the middle. Thorax rather strongly transverse, the front angles 

 extremely rounded off and indistinct, and not projecting farther 

 forwards than the middle of the front maa-gin ; the disc sparingly 

 and obsoletely punctured, the explanate yellow sides more distinctly 

 punctured. Elytra rather narrow and elongate, with their apices 

 prolonged, and the prolonged portion abruptly bent down ; they are 

 rather finely striate, but the interstices are somewhat convex, and 

 the seventh is elevated at the shoulder ; the strias are provided with 

 fine distant impressions or punctures ; on the apical, and more 

 especially on the lateral-apical portion, the sculpture becomes deeper 

 and coarser, so that the outer stria bears some very large deep 

 impressions. On the uuder-surface it is seen that this apical portion 

 of the wing-cases projects quite beyond the hind-body. The two 

 individuals described are females. 



The species appears structurally very similar to the European 

 and North American species of Nccropkilus, and the peculiar form 

 and sculpture of the wing-cases would not at present justify its being 

 treated as a distinct genus.

Posterior coxcb contiguous. Maxillary palpi not much longer 

 than the labial. Prothorax narrowed anteriorly. Hind trochanters

 of the elytra.

 Ligula corneous, dilated towards the front, its apex rounded. 

 Lobes of the viaxillcB sub-equal ; the inner the larger, ciliated 

 inwardly and at the extremity; the external filiform, very slender, 

 pubescent at the apex. Labial jja//;i with the basal joint very short, 

 second pyriform, third rather shorter, globose and acuminate ; first 

 joint of the maxillary also short, joints 2-4 globuliform, fourth 

 pointed. Mandibles terminating in two sharp elongate hooks. 

 Lahrum very small, concealed below the clypeus. Head very broad, 

 narrowed and obtuse in front, deflected. Antennce g-articulate, 

 basal joint stout, oviform; second long and slender; third about half 

 as long as its predecessor; joints 4-7 short; eighth very robust, cam- 

 panulate ; ninth not so broad, ovate. Prothorax short, rounded at 

 the base, where it equals the elytra in width, narrowed anteriorly. 

 Scutellum large, triangular. Elytra very convex, gradually narrowed
