 By Captain Thos. Broun. 



[Continued from p. 88.] 



Group ColydiidaB. 



Coxelus thoracicus, sp. n. 



Chiang^ opaque, ferruginous ; clothed with short, erect, 

 pale and dark setiforrn squamai ; legs and antennaj paler red. 



Head granulate ; epistome nearly smooth, separated from 

 the sides by oblique depressions ; the set» rather slender, 

 yellow. Eyes small, with apparently an external swelling 

 behind and below each. Antennce 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. Ehjtra with coarser setas 

 than the thorax, their sculpture quite serial and regular ; 

 there is a small scutellar depression only ; the base is 

 medially emarginate, but nearly truncate towards the sides, 

 so that the humeral angles are almost rectangular. Tibi(e 

 with short slender seta3. 



Underside dull, bearing fine yellowish set^e ; metasternum 

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

 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 seta3. 



No, 35L — Like No. 350, tibi« with fine hairs only.
