of the clypeus sub-foveate, prothorax finely and equally sliagreened, 

 supra-marginal carina rounded laterally towards the base, and 

 produced there in a very sharp angle, the lateral margin is grooved 

 for three-fourths of the length, and the central part of the disk has 

 an ill-defined longitudinal line hardly noticeable beyond the middle 

 and nearly ending in a slight depression in the centre of the base ; 

 elytra with distinct striae, intervals as finely shagreened as the 

 prothorax, upper angle of the lateral emargination rounded ; pygi- 

 dium very finely granulose ; metasternum absolutely similar in shape 

 and sculpture to that of G. humeralis, but not impressed transversely 

 at tip. 



Length 11 mm. ; width 6 mm.

Bright coppery-red on the upper part with the sides beneath and 

 the legs greenish, or totally metallic green ; head covered with 

 minute and closely set elongate granules and having in the centre 

 a narrow longitudinal smooth carina beginning as a small smooth 

 patch at the base and ending in the centre of the bidentate clypeus ; 

 prothorax very convex, covered with very closely set elongate 

 granules, and having in the centre a broad, raised, smooth, band 

 reaching from the apex to a short distance from the base, and a 

 curved patch and a smaller one, also raised, on each side ; elytra 

 narrowly and not very distinctly striate, intervals closely shagreened, 

 second interval with three very broad and deep transverse impres- 

 sions in the middle ; pygidium closely granulose ; metasternum 

 aculeate at tip, faintly punctulate in the centre, and without any 

 distinct median groove or impression ; sides of pectus and also 

 outer part of posterior femora clothed with a silky white pubescence. 



Length 9 mm. ; width 6 mm. 



The nearest ally of this species is G.fulgidus, Oliv., from Senegal. 

 As for G. smaragdinus, Fahr., being identical with G. ignitus, there 

 is, I think, little doubt of it, judging from the description, although 

 in the co-type which I examined the longitudinal line and patches of 

 the prothorax were not much more raised than in some examples of 

 G. virens ; these lines and patches do not appear so much raised in 

 the green variety (G. smaragdinus), but it is simply an optical illusion.
