XXIII. — Descriptions of new Coleopt era from New Zealand. 

 By Captain Thos. Broun. 



[Continued from p. 88.] 



Group Colydiidae. 



Coxelus thoracicus, sp. n. 



Cblong, opaque, ferruginous ; clothed with short, erect, 

 pale and dark setit'orm squama? ; legs and antennae paler red. 



Head granulate; epistome nearly smooth, separated from 

 the sides by oblique depressions ; the sette rather slender, 

 yellow. Ei/es small, with apparently an external swelling 

 behind and below each. Antenme finely pubescent, first 

 joint scarcely discernible from above, second rather large, 

 third slightly longer than fourth, the following five short ; 

 tenth abruptly enlarged, eleventh not so broad as the pre- 

 ceding one. Thorax subquadrate, slightly curvedly nar- 

 rowed towards the prominent front angles, nearly straight 

 and but little narrowed posteriorly ; marginal channels rather 

 shallow, the sides less explanate behind than in front; the 

 disk is without well-marked impressions, but, close to the 

 basal margin, there is a linear transverse impression which, 

 in front of the scutellum, becomes a sort of fovea ; the 

 granules on its surface are rather distinctly separated from 

 one another, they are not large. Elijtra with coarser seta3 

 than the thorax, their sculpture quite serial and regular ; 

 there is a small scutellar depression only ; the base i.s 

 medially emarginate, but nearly truncate towards the sides, 

 so that the humeral angles are almost rectangular. Tibiae 

 with short slender seta3. 



Underside dull, bearing fine yellowish setae ; metasternum 

 granulate, the rest of the sculpture more or less indefinite j 

 fourth ventral segment depressed behind. 



Var. — Body piceous ; legs and antennae pale brick-red ; 

 granules on thorax coarser; size larger (l^X ^). 



Length 1^, breadth f line. 



Wellington. Discovered by Mr. J. H. Lewis on the 

 underside of wet stones just above high- water mark. 



Ohs. I have selected two or three diagnostic characters of 

 each species as an aid to identification: — 



No. 350. — Thorax uneven, elytra without depressions, 

 tibiae with coarse set£e. 



]S'o. 351. — Like Ko. 350, tibiae with fine hairs only.
