AspoNQopus Faeleti, n. sp. 



Castaneous, with obscure green reflexions, thickly and coarsely punctured. 

 Antennffi black, 1st and 3rd joints sub-equal, shorter than 2nd, 4th longest, in- 

 crassated, obsoletely sulcated, apical joint somewhat shorter than preceding, narrowly 

 fuscous at tip. Head emarginate at apex, sides sinuated. Eostrum piceous, apical 

 joint paler. Base of pi'onotum and scutellum somewhat rugulose. The green 

 reflexions are jDrincipally observable at base of prouotum, apex of scutellum, and 



apical half of corium. Membrane castaneous. Abdomen above rufous. 



Long. 17 mm. 

 Nortli Nyassa (Farley). 



This species is allied to A. viduatus, Fab., from wliich it is struc- 

 turally distiuguislied by tbe length of the 2nd joint of the antennse, 

 and the strongly incrassated and sulcated appearance of the 4th joint. 

 The colour of the abdomen iibove, and absence of the black frontal 

 markings of the pronotum, also prevent confusion. 



EEDUYIID.E. 



Genus PLATYMEBIS, Lap. 



Plattmeeis conffsa, n. sp. 



Black, a large sub-quadrate spot abnut centre of corium, and femora near apices 



banded with luteous. Pronotum with frontal lobe armed with a short spine on 



each side, and deeply excavated and furrowed. Posterior lobe with the disc elevated, 



on which is a faint central longitudinal impression, and the lateral angles produced 



into acute spines directed backwards. Antennse, with the exception of the basal 



joints, obscure castaneous, pilose. Legs pilose, the femoral luteous bands broadest 



on fore femora, and narrowest on the posterior. Abdomen above rufous, with the 



sides and apex black. Membrane somewhat paler, and obscui'e fuscous.

Nyassa. 



This species is allied to P. Itliadamantlms, Gerst., from which it 

 is separated by the armature of the anterior lobe of the prouotum. 

 The three allied East African species can be thus identified : 



A. Lateral angles of posterior lobe of pronotum produced into acute spines. 



a. Anterior lobe of pronotum unarmed Mhadamanthus, Gerst. 



h. Anterior lobe of pronotum with spine on each side covfusa, Dist. 



B. Lateral angles of posterior lobe of pronotum rounded. 



c. Anterior lobe of pronotum with spine on each side guttatipennis, Stal. 



I have lately received from the northern end of Lake Nyassa 

 five specimens ( J & ? ) of Plafymeris Rhadamanthus, Gerst. They 

 differ from the figure of that species in the " Eeise in Ost-Afrika" 

 in having the spot on the corium, as well as the femoral markings, 

 rufous. They are also rather larger in size.
