136 On Two Species of Cicadidae. 



XX. — Two apparently undescribed Species of Cicadidse 

 from Tropical Africa. By W. L. DISTANT. 



The two species o£ Ugada here described are in the Collection 

 of the British Museum, a collection now, without a doubt, 

 the finest and most comprehensive in the world. 



Ugada nigrofasciata, sp. n. 



Body dark castaneous bro \ n ; pronotum with a broad 

 transverse black fascia at the anterior margin of the posterior 

 area of the pronotum, which is dull ochraceous, and the 

 extreme posterior margin of same, black ; mesonotum with 

 four small dark obconical spots, on anterior margin of which 

 the two central ones are largest, and a longer but more 

 obscure spot on the lateral areas ; abdomen above darker in 

 hue with the segmental margins narrowly ochraceous, the 

 three terminal segments thickly whitely tomentose ; body 

 beneath with the pronotal angular dilatations, the tibiae and 

 rostrum — excluding base — black or blackish ; base of rostrum, 

 streaks to coxa? and trochanters, and the opercula in <$ , 

 ochraceous ; tegmina dull greyishly opaque, excepting on 

 apical area where it is marginally, submarginally, and on 

 most of postcostal area vitreous, the venation black and the 

 basal cell thickly, pale stramineously tomentose, the costal 

 membrane ochraceous ; wings pale castaneous brown, the 

 venation darker in hue, the posterior marginal area vitreous, 

 darkly suffused near anal angle ; pronotal angles strongly 

 angularly produced ; head including eyes about two-thirds 

 the width of base of mesonotum; rostrum reaching base of 

 posterior trochanters ; face strongly centrally longitudinally 

 sulcate and on each side strongly transversely sulcate.

Ugada atratula, sp. n. 



Body black, eyes shining black ; lateral areas and posterior 

 marginal area of pronotum, sternum, and opercula more 

 fuscous in hue ; legs black ; tegmina with about basal half 

 fuscous brown where all the veins are somewhat broadly 

 piceous, remaining area hyaline or subhyaline, the veins 

 black, a subapical fuscous angulated fascia crossing the 

 unional veins of the four upper ulnar and apical areas and 

 marked with a few pale spots and a somewhat similar apical
