Broun.— New Genera and Species of Coleoptera. 433 



Femora incrassate, the posterior particularly; hind tibiae with a pale, 

 very elongate terminal calcar. These two characteristics at once differen- 

 tiate this species from its allies. In general appearance C . aethiops (1730) 

 most nearly resembles it. 



An aberrant .species, probably representing a distinct genus. 



Length, nearly 3 mm. ; breadth, quite Ik mm. 



Silverstream. Both of my specimens were discovered by Mr. A. 

 O'Connor, of Wellington. 



Group Mei.vridak. 



3247. Arthracanthus foveicollis sp. nov. A rthr acanthus Broun, Man. N.Z. 

 Coleopt., p. 781. 



Elongate, slightly nitid; pubescence greyish, slender yet quite dis 

 tinct; elytra, legs, and basal four joints of antennae more or less infus- 

 cate, tibiae rather more rufescent, remaining joints of antennae piceous, 

 head and thorax nigrescent. 



Head slightly broader than thorax, with a large median fovea behind; 

 it is finely and distantly punctate. Eyes large and prominent. Thorax 

 of equal length and breadth, obtusely dilated laterally at the middle, 

 distinctly but finely and rather distantly punctiired, with a median linear 

 impression in front, a basi.l fovea at the middle, and a shallow impression 

 at each side. Scutellum distinct. Elytra elongate, subparallel, wider 

 than thorax at the base ; distinctly, moderately closely, and rugosely 

 punctured. 



Antennae stout, not serrate, basal two joints thick, 3-5 moderately 

 elongate and about equal, 6-10 similarly elongate, 9th and 10th somewhat 

 triangular, 11th elongate-oval. Legs elongate, the basal joint of the 

 anterior tarsi with a spiniform process at its front or inner angle. 



Female. — Occipital fovea absent. Basal joint of anterior tarsi very 

 short, not distinctly spinose. 



The thoracic fovea is distinctive. 



Length, 2|mm.; breadth, § mm. 



Akatarawa, Wellington. Two specimens, mounted on cardboard, from 

 Mr. A. O'Connor. 



Croup Ct.eri.dae. 



3248. Phymatophaea griseipennis sp. nov. Phymatophaea Pascoe, Man. 

 N.Z. Coleopt., p. 334. 



Elongate, subdepressed, with numerous erect, slender greyish setae, 

 subopaque; nigrescent, but the elytra, with the exception of their basal 

 portion, are yellowish-grey; antennae and tarsi infuscate. 



Head very closely and coarsely punctured. Thorax of about equal 

 length and breadth, obtusely dilated laterally behind the middle, its punc- 

 tation hardlv as close and coarse as that of the head, finer in front, with 

 a pair of smooth, slightly raised spots before the middle. Scutellum sub- 

 triangular. Elytra thrice as long as thorax, not twice its width at the 

 base, rather wider behind, without inequalities of surface; evenly punc- 

 tured, more coarsely but not quite so closely as the thorax. 



Legs pilose, anterior tibiae moderately curved. Tarsi with well- 

 developed membranous appendages, claws thickened but not dentate. 

 Eyes prominent, finely faceted, emarginate in front. 



Length, 5 mm. ; breadth, If mm. 



Silverstream, near Wellington. A single specimen, from Mr, A. 

 O'Connor.
