Homoptera from Southern Africa. 129 



This species may at once be distinguished from P. plumosa 

 and P. deusta hy the absence of the central black fascia to 

 the pronotum. It is allied to P. plumosa by the wide and 

 relatively short pronotum, but differs by the broader tegrnina, 

 shorter abdomen, different markings of the tegrnina, &c. 



MONOMATAPA, gen. nov. 



Body short, robust, widest about centre of abdomen. 

 Head broad, at outer margins of eyes a little wider than 

 mesonotum ; ocelli about twice the distance from eyes as 

 from each other ; face broad, not prominently tumid, longi- 

 tudinal sulcation narrow, transverse ridges prominent. Meta- 

 notum concavely excavated posteriorly ; basal segment of 

 abdomen subacutely and convexly produced anteriorly. 

 Opercula rather large, directed inwardly, much widened 

 posteriorly. Tympana completely exposed. Tegrnina with 

 the basal cell longer than broad and the ulnar veins at end of 

 same widely separated ; interior ulnar area a little narrower 

 at base than apex ; apical areas eight. 



Alonomatapa, which, by the exposed tympana, belongs to 

 the division Tibicenin^e, has a somewhat superficial resem- 

 blance to the genus Tympanoterpes. 



Monomatapa insignis, sp. n. 



Body above black ; eyes, pronotum (excluding central 

 longitudinal fascia), and the exposed tympana dark casta- 

 neous ; abdomen rather thickly greyishly pilose ; body 

 beneath and legs black ; tibiae and tarsi more or less casta- 

 neous or ochraceous ; opercula ochraceous ; lateral areas of 

 the body and opercula thickly greyishly pilose. 



Tegrnina and wings pale hyaline; the iirst with the vena- 

 tion blackish, the base narrowly, basal cell, and outer edge of 

 costal membrane ochraceous. Wings with the venation 

 blackish, the base ochraceous, with a darker spot on the abdo- 

 minal area. 



Rostrum short, about reaching the intermediate cox£e ; 

 opercula extending over the basal segment of the abdomen, 

 obliquely directed inwardly, widened posteriorly. 



Long. ^ 27 millim. ; exp. tegm. 80 rnillim.
