Compsus adonis, sp.n. (Plate IV, fig. 11.) 



5. Integument black, completely hidden by dense scaling; the 

 upper surface of the prothorax and elytra pale sage green, with 

 most of the more raised portions chalky white, and spangled all 

 over with minute metallic green scales; the head, front margin of 

 the prothorax and apex of the elytra covered with iridescent coppery, 

 golden and green scales ; the lower surface pale blue-green through- 

 out, vnth. scattered metallic green scales; the legs metallic green, 

 with a golden tinge on the tibiae, and the apices of the femora 

 brilliant cobalt- blue. 



Head with the forehead slightly depressed transversely and with 

 a small round fovea; the eyes more obliquely inserted than usual, 

 so that when viewed from above the inner edge slopes inwards at 

 an angle of 45". Boslnm much longer than the basal width and 

 markedly dilated at the apex; the dorsum convex, without any 

 furrow, and with a deep oblique impression on each side, the inter- 

 antennal space deeply excavated, with a broad shiny bare line 

 down the middle. Antennae, with the scape comparatively slender 

 and gradually clavate, Avith obliquely raised pale setae ; the funicular 

 joints in order of length : 2, I, 3, 4, (5, 6, 7), the apical joints oblong. 

 Prothorax as long as broad, parallel-sided from the base for two- 

 thirds the length, then gently narrowing, with a distinct apical 

 constriction ; the apical margin not sinuate beneath ; the dorsum 

 verj' coarsely and rugosely punctate and slightly flattened in the 

 middle. Scvtelluvi almost an equilateral triangle, broadest behind, 

 squamosc. EJijIra oblong-ovate, the line from the external basal 

 angle to the shoulder straight and oljlifjue, the shoulder forming 

 an obtuse angle; the apices each produced into a densely scaly 

 and setose process about 0-6 mm. long; the longitudinal outline 

 (|uite flat, the declivity with a slope of about 60'' ; the dorsum with 

 regiilar rows of large deep foveolae, w^hich are entirely covered with 

 scaling except for a small hole in the centre; the sutural area 

 markedly flattened, so that interval .3 appears somewhat prominent, 

 but is not truly costate ; the posterior callus on int. 5 distinct but 

 obtuse; the scales small, circular and overlapping; the irregular 

 setae small, sparse and recumbent. Lcfjs slender, with raised pale 

 setae; the tibiae not denticulate internally; second joint of hind 

 tarsi slightly longer than broad, the clav.'s with a small lateral seta. 



Length, 14 mm. ; breadth, o mm.
