Second and third joints of antennae of equal length. 



Abdomen above rufous. Long., ^ , 12 mm., $ , 15 ram nigro-violaceus. 



Second joint of antennae somewhat longer than the third. 



Abdomen above cyaneous. Long., (?,14! — 16 mm., ? , 17 — I'd ra.\n.... viduatus. 



AspojfGOPUS AFri>'is, n. sp. 



Dark shining green, thickly and coarsely punctured ; pronotum rugulose, scu- 

 tellum transversely rugose. Fi-ontal and lateral edges of pronotum, a small central 

 spot at base of scutellum, basal half of border of corium above and below, and ab- 

 dominal border above, luteous. Antennae narrowly and obscurely fuscous at tip, 3rd 

 and 5th joints equal, 2nd joint minute, 4th joint incrassated towards tip, shorter 

 than the 3rd and oth. Head strongly emarginate in front, with the lateral lobes 

 broadly reflexed. The luteous border of the pronotum is widest in front, where it 

 contains the two usual sliglitly raised prominences. The lateral edges are strongly 

 reflexed. Membrane dark fuscous. Under-side coarsely punctate. Coxae, tro- 

 chanters, and lateral sides of prosternum, very broadly luteous. Abdomen below 

 dark greenish-testaceous, much more prominently testaceous on disc, and green 

 towards lateral borders. Femora obsoletely spinous, hind tibiae somewhat dilated 

 except at base and apex, dilated portion distinctly sulcate. Eostrum luteous at base.

Isubu (W. Africa). 



AUiod to A. pafruelis, St?il, from which it can be at once struc- 

 turally distinguished by the broadly reflexed lateral borders of the 

 pronotum. 



ASPOXGOPFS DIVERaEKS, «. Sp. 

 Above fuscous, shining, strongly rugose and punctate. Head and antennae 

 bi-assy-black. Head strongly emarginate in front, lateral lobes, slightly sinuate, 

 strongly reflexed. 2nd and 3rd joints of antennae sub-equal, 4th somewhat com- 

 pressed, obsoletely sulcated above, rather shorter than apical joint, which is the 

 longest. Pronotum with the lateral angles moderately produced and rounded. 

 Corium rather paler in colour. Membrane concolorous, but largely suffused with 

 brassy-green, which in some specimens appears only at apex, and in others more so 

 throughout the membranal area. Abdomen above castaneous, with the margins 

 brassy-black. Under-side of body and legs brassy -black, thickly and finely (the legs 

 more coarsely) punctate. Femora obtusely spinous, tibiae strongly sulcated.

The prominence of the lateral angles of the pronotum sufficiently 

 distinguishes this from any other known African species of the genus. 

 Its somewhat elongate form and sulcated tibiee also give it a charac- 

 teristic which is slightly divergent from the typical forms of Aspongo- 

 pus. In all essential characters, especially in the size and shape of 

 the head and the broad and rounded scutellum, it agrees perfectly 

 with that genus. 



ASPONGOPUS MODESTUS, 11. sp. 

 Ovate, bronzy-black. Head, pronotum and scutellum thickly and coarsely 

 punctured, the last transversely rugulose. Corium thickly and finely punctured. 

 Head sli2;ht!v emarginate in front, with the lateral lobe obsoletely reflexed. An-
