portion, to a variable extent, and the suture green, an outer 

 marginal border dilated inwardly at the sutural angle, a large 

 spot sometimes preceded by one or two smaller ones next the 

 suture behind and several irregular spots between the discal 

 costae, Avhite. Pygidium closely strigose ; black, with an 

 oblique white spot on each side. Beneath greenish-black, 

 broadly white at the sides, metasternum green and punctured 

 in the centre, mesosternal process very short and obtuse, abdo- 

 men impressed and spotted with white in the centre. Legs 

 red-brown or pitchy, coarsely punctured, vmderside of the 

 anterior and posterior, and edge of the intermediate femora 

 white, anterior tibiae with two strong lateral teeth, the apex 

 strongly produced, intermediate and posterior tibiae with a slight 

 tooth on the outer side, apical spurs of the latter very long. 

 The female is rather broader, with the abdomen convex and 

 unspotted in the centre, the anterior tibiae broader and the teeth 

 on the intermediate and posterior tibiae much stronger. Length 

 11-12 mm. 



Congo District, W. Africa. 



I am indebted to Dr. E. Candeze for several specimens of this 

 pretty species, it is closely allied to G. Jdrta, Burm., but differs 

 in being of a smaller size, more closely punctured, in having the 

 thorax less rounded at the sides and not so deeply emarginate 

 before the scutellum, and the elytra bordered, not spotted, with 

 white on the outer margins. The white spots on the elytra are 

 liable to much variation both as regards their size and number, one 

 of the specimens before me having only two small ones between 

 the costae and one next the suture, whilst another specimen has 

 a row of six between the costae and two additional ones next the 

 suture, the number generally varying on the two elytra of the 

 same individual, the extent of green at the apex is also variable, 

 some specimens having the apical callosity alone of that colour, 

 and in others it extends to the middle ; the lateral white bands 

 on the thorax are sometimes dilated at the posterior angles and 

 extend along the basal margin nearly to the scutellum, and in 

 one specimen there are two minute white discal spots, and 

 another has a slight impressed white median line towards the 

 base.
