always easily distinguished by the quite différent structure of the 

 génital segment. 



2. — Ennius longulus Germ. 



Tlie dark colour of the head, membrane, and underside of the 

 body varies much in intensity, being sometimes entirely black, 

 except a narrow latéral margin to the venter; The third antennal 

 joint is also variable in length. The five narrow less densely punc- 

 tulate posterior vittae of the pronotum are often very indistinct. 

 E. Monteironis DisT. is not distinct from longulus. Stâl's descrip- 

 tion of the colour of the legs is rather obscure and ambiguous; 

 normally they are coloured as described bv Distant. I know the 

 speciesfrom Rhodesia and Nyasaland. My.northernmost spécimens 

 are from Harrar, Abyssinia.

Above variegated with dark ochraceous and blackish, the black parts 

 often with a greenish tinge, pronotum with two small round calions spots 

 before the middle and a subtriangular patch at the middle of the latéral 

 margins pale ochraceous, scutellum with fîve more or less irregular pale 

 ochraceous basai spots, the outermost spot on each side more calions and 

 tonching the black pit at the basai angles, connexivum black with a trans- 

 verse médian inwardh^ strongl}- narrowing pale ochraceous spot, the whole 

 upper side of the body rather thickly punctured, but the ochraceous parts 

 much more remotely so; beneath ochraceous, head between the bucculae 

 and the sides greenish black, variegated and streaked with ochraceous, 

 pleurae greenish black, strongly punctured, with a médian more or less 

 interrupted vitta and a triangular patch at the latéral margin of the propleurae 

 ochraceous and impunctate, mesosternum with a large médian fuscous patch, 

 the venter with a broad infuscated sublateral vitta tinged with greenish and 

 emitting fuscous branches to the latéral margin along the basai and apical 

 margins of the segments, spiracles piceous, iîfth segment with two basai 

 médian spots, and sixth segment with a large médian basai spot black. 

 Head almost as long as broad, anteocular part broader than long^ subparallel, 

 ver}^ sliglitly sinuate at the sides, broadly rounded at apex, juga in their 

 middle twice broader than clj^peus, ocelli a little less than three times more 

 distant from each other than from eyes, rostrum piceous, reaching base of 

 third ventral segment, antenuae black, fîrst joint beneath, and articulation
