7ieiv Specie.'^ of Fuhjoruls. 555 



flat, ovipositor complete. proj( cling beyond end of a])donien;, 

 iinal segment small. 



Described from one male and one female, tlie male from 

 Mt. Mlanje, Nyassaland (S. A. Neave, 4. xii. 1912), and the 

 female from South-east Katanga {S. A. Neave^ 29. ii. 1907). 



Brixia stannusi, sp. n. 



Female. — Length 3, tegraen 5 mm. 



Head as in B. speciosa, the 2nd segment of antennae not 

 quite so long. Tegmina typical. Lateral margins of 

 pygofer rounded, medio-ventral process small, angului-. 

 Genital styles fairly large, narrow at base and slightly 

 increasing in width, the apex produced into two processes 

 forming a sub-crescent, the outer process larger than the 

 inner. Anal segment reaching to apex of genital style, 

 longer than broad, slightly widened to apex which is 

 rounded. 



Yellow ; three small black marks in front of eyes. 

 Tegmina hyaline, slightly ochraceous ; cross-veins and apical 

 cross-veins brown, the apical margin dark, apices of apical 

 veins light ; veins with small granules the same colour as 

 membrane. Wings hyaline with brown veins. 



One male from Zomba, Nyassaland {H. S. Stannas, July 

 1914). 



Mnemosyne cuhancBy Stal. 



Mnemosyne, StSl, Hem. Afr. iv. p. 150 (1866), no species mentioned ; 

 Stal, Berl. ent. Zeit. (1866), tvpe-species cuhancB described ; Fowler, 

 Biol. Centr.-Amer., Horn. i. p.^102 (1904) ; Distant, Faun. Brit. Ind., 

 Rhyn. yi. p. 33 (1916). 



This genus was described and placed by Stal next to Cajeta 

 in the Dictyopharidre, but both these genera belong to the 

 Cixiidse. Both Fowler and Distant redescribed the genus, but 

 there was some confusion, as the five mesonotal carinae are 

 absent or obscure in some species, or appear as three. The chief 

 distinction between this genus and Oliarus or Cixius lies in 

 the branching of M; in Mnemosyne the forking of M^ and Mo 

 is some distance away from Mf, but the forking of J/3 and M^ 

 is close to 31f; in Oliarus and Cixius the reverse is the case, 

 Ml and J/o forking near to Mf 'diu\ il/3 and M.^ some distance 

 from it. The median carni?e on frons and elypeus are often 

 obscure or absent. In most of the species granules bearing 

 macrotrichia are present in greater or less numbers on 

 the membrane, especially in the apical cells. 



The type-specimen is a male. The anal segment is lar^e, 

 a little longer than broad, sides rounded, broadest slightlv
