Bronze, sub-opaque or very moderately shining on the upper side,, 

 darker bronze underneath, legs of the same colour as the under side, 

 but sometimes with a slight violaceous tinge ; head and prothorax 

 covered with very minute, closely set granules ; the latter has a very 

 fine longitudinal smooth median line, often quite indistinct, and 

 reaching from the base to about the middle ; the outer margin is 

 slightly crenulate, hardly duplicate, distinctly sinuate beyond the 

 median part and a little attenuated towards the base where it is 

 slightly angular ; elytra narrowly striate, intervals finely and 

 equally shagreened ; pygidium shagreened ; metathorax produced in 

 a somewhat blunt triangle at apex, slightly impressed transversely 

 at base, and having a fine impressed line reaching from the basal 

 impression to a short distance from the apex ; it is fairly closely 

 punctured at middle, and granulosa in front and laterally ; in the 

 male the anterior tibiae are a little thickened at tip, very slightly 

 sinuate below the second external tooth, and not mucronate inwardly 

 at tip. 



Length 17-19 mm. ; width 11-12 mm. 



This species is very closely allied to G. consocius, but it is more 

 distinctly shagreened on the upper side, and it is always larger ; it 

 is distinguished from G. fastiditus by the apical part of the meta- 

 sternum having no transverse impression, and being much less pro- 

 nounced ; the anterior tibiae of the male are not so much ampliated,. 

 nor so conspicuously emarginate inwardly at tip. 



Mr. Waterhouse has himself identified this species as his G- 

 delagorguei.
