Compsus pugionatus, sp. u. (Plate III, fig. 7.) 



(j$. Integument black, covered with scaling which is either 

 uniformly pale blue-green (type) or uniformly pale coppery; the 

 scales fairly dense on the head, rostrum, legs and lower surface; 

 on the pronotum (in unabraded specimens) the elevated parts are 

 squamose, the hollows of the foveae and sinuous impressions being 

 bare ; the elytra, on the contrary, have the raised parts bare, the 

 scaling being dense in the foveae, leaving a bare pin-hole in the 

 centre. 



Head coriaceous beneath the scaling, with a small frontal fovea, 

 and the front margin of the eyes shallowly impressed. Rosirv.m 

 longer than the basal width, gradua,lly dilated fiom base to apex, 

 and with a few sparse punctures ; the interantennal area moderately 

 excavated and divided by a faint median ridge ; the dorsum convex, 

 with a narrow smooth median line and a very faint small oblique 

 impression on each side (often obsolete). Atitennae with the scape 

 exceeding the ej'e, slender, gradually clavate, with recumbent pale 

 setae and sparse pubescence ; the funicular joints in order of length : 

 2, 1, 3, 4, (5, 6, 7), the terminal ones longer than broad, ovate. 

 Prothorax as long as broad, widest at the base and gradually nairow- 

 ing in front, the sides feebly rounded and with a shallow apical 

 constriction; the gular margin shallowly sinuate; the dorsum 

 with a shallow median impression containing twisted impressed 

 lines and punctures, the lateral areas not impressed and with similar 

 coarse sculpturings. Scutellum squamose, narrowly ovate in ^, 

 broader in $. Elytra subtriangular, the shoulders very prominent 

 and forming an acute angle, the apices separately joroduced into a 

 long sharp process; the dorsal outline almost flat from the base 

 to the top of the declivity, wliich has a slope of 45°; the dorsum 

 reticulate, with regular rows of large rounded punctures, the intervals 

 narrow and undulating, interval 3 rather more prominent than the 

 others owing to the slight flattening of the sutural area ; no posterior 

 callus; the scales small, round and slightly overlapping; the setae 

 sparse, minute, recumbent and discernible with difficulty, those 

 on the apical processes longer and raised. Legs with slightly raised 

 pale setae ; the tibiae not denticulate internally, the hind pair with 

 a short mucro in the ^^ only; the second joint of the front tarsi 

 longer than broad, the claws with a short lateral seta. 



Length, 12-25-18-5; breadth, 4-5-6-5 mm. 



Described from fifteen specimens. 



Eeadily distinguished by its sharply pointed shoulders. 

 I have retained for it King's manuscript name, under which 

 it usually stands in collections.
