Anal segment longer than broad, sides slightly convex, apex roundly 

 emarginate ; pregenital plate large, longer than wide, angularly produced on 

 hind margin, the sides of the angle being slightly concave, projecting beyond 

 the base of the styles, slightly tutnid along the basal edge. 



Length 5 mm. ; tegmen 13 mm. 



Hah. PoETiTGUESE East Afeica, Valley o£ the Kolo River {S. A. 



Neave, viii, 1913) ; Natal, Durban. ' 



One female from each locality, the type being from the Kolo River. 

 There are specimens from West Africa in the British Museum which are 

 distinct from this species, and which I consider to be Z. sinuosa ; they 

 are both related to Z. pteroplioi^oides (Westw.). 



Z. ridleyi, sp. n. 



c^*. Antennae slightly longer than face, cylindrical ; four cubital veins 

 entering the hind margin ; wings one-half the length of the tegmina. 



In coloration this species is similar to Z. riifivena Dist. and Z. cumnlata 

 (Walk.). 



Brown ; legs, antennae, and carinae of mesonotum lighter, abdomen thickly 

 irrorated with lighter spots. Tegmina light fuscous, thickly mottled with lighter 

 spots, veins reddish, the lighter marks numerous along the median sectors, 

 numerous in radial cell, and occupying most of the costal and subcostal cells; 

 wings fuscous with reddish veins. 



Anal segment long and narrow, sides sloping steeply except at the apex, 

 which is truncate and, in lateral view, curved into a semicircle, anus in the 

 middle of segment, in lateral view deep until the carved apex; genital stj'les 

 long, narrow, reaching to the apex of the anal segment, narrowest at bsise and 

 apex, widest in the middle, apex truncate, ventral edge as seen from the side 

 slightly sinuous, entire, dorsal edge angularly produced to the middle. 



Length 4*2 mm. ; tegmen 10 mm. 



9. Tegmina darker in colour than in the male, the light spots not so 

 large. Pregenital plate large, about as long as wide, posterior edge slightlv 

 and angularly produced. 



Length 4"8 mm.; tegmen 12 mm. 



Hah. Singapore {H. H. Ridley, 1903). 



One male, the type, and one female, both in the B.M. coll. 



Z. JcirJcaldyi, sp. n. 



Zoraida cumulata Dist. nee Walk., Fauna Brit. Ind., Rhynchota, iii, 

 p. 301. 



Antennae a little longer than the face, cylindrical ; carinae of face not 

 meeting. In coloration it is very near Z. ndleyi, the brown is darker and on 

 the tegmina the light marks are much smaller along the median sectors and 

 cubital veins; a large dark patch in the apical, subcostal, and radial cells.
