on proximal half extends to end of stigma and down to fifth

Cape Colony, South Africa. — Two specimens (co-types) : 

 one individual from Pirie Bush, near King AVilliam's Town 

 (A. N. Stenniny) ; the second specimen without precise 

 locality or other data. These are the two specimens referred 

 to by jMiss Ricardo (Ann. & Mag. Nat. Hist. ser. 7, vol. v. 

 1900, p. 101), who, however, was prevented from seeing that 

 both belonged to the same species, since at tiie time when 

 her paper was written the specimen without data was not 

 set, and its abdomen was consequently concealed by its 

 wings. 



Cadicera quinqiiemaculata cannot be confused with any 

 of the other species of this genus at present described, from 

 which the markings of the tibiae are alone sutfieicnt to 

 distinguish it without difficulty. It presents, however, a 

 deceptive resemblance in general appearance and markings 

 to Corizoneura obsctira, llieardo, the type of which is 

 from Blantyre, Nyasaland Protectorate. Nevertheless, apart 

 from other differences, the Corizoneura can be distinguished 

 by the hair on the under side of the head beiug yellowish 

 white instead of blackish brown, by that on the pleurae being 

 largoly yellowish instead of entirely blackish brown, by the 

 much duller tibise, the burnt-umber tips of which do not 

 present nearly such a sharp contrast to the remainder, and by 

 the hind tarsi being entirely russet. 



Miss Ricardo's statements {loc. cit. p. 100) that in 

 Cadicera " ocelli are present " and that in C. rubramaryinata, 

 Macq., ocelli are '' present and distinct " are somewhat 

 misleading, as will be seen from the following results of an 

 examination of the Museum material belonging to this 

 genus. The single specimen (a ? ) of C. rubrainarginata in 

 the Museum collection has the anterior ocellus alone ; a (^ 

 and two ? ? of C. melanopyya, Wied., show no ocelli, but a 

 third ? of this species has the anterior ocellus alone, which 

 is very minute ; in one of four $ ? of C. chrysostiyma, 

 Wied., there is a still more minute anterior ocellus, but the 

 other two ocelli arc wanting, and the remaining spcciuiens 

 of this species cxhiiiit no trace of ocelli whatever; the single 

 specimen (a (5' ) of C, crassipalpis^ Macq., has likewise no
