On Cicadidee from the Malay Archipelago. 369 
slightly more yellow; the spot in the cell and those of the 
discal series of the primaries nearest to the costa decidedly 
smaller: secondaries with the external blackish border occu- 
pying nearly half the wing and crossed by large well-defined 
spots of the ground-colour; a marginal series of small white 
spots. Below, all the pale markings are reduced and the 
brown areas consequently much broader; the pale bands also 
are cream-coloured, not pure white, and the yellow streaks 
and spots deeper in tint. 
Expanse of wings 62-68 millim. 
Bolivia. Three males. 
6. Catasticta Staudingeri, sp. n. 
Allied to C. coreyra, with which it has been confounded ; 
it differs above in the restriction of the black apical patch of 
the primaries, which becomes linear from the second median 
nervule ; on the under surface the apical border is broadly 
bright yellow and traversed by two grey lunular markings ; 
the secondaries are bright yellow, the veins black, with white 
borders; in the markings of these wings it differs from 
C’. corcyra in having the irregular postmedian stripe placed a 
little nearer the outer margin and in having a well-defined 
boldly zigzagged submarginal brown line, the outer angles 
of which terminate on the margin at the extremities of the 
nervures. 
Hixpanse of wings 54 millim. 
HK. Peru. One male (type), B. M. 
Also five examples from Kcuador in the Hewitson collec- 
tion labelled as C. coreyra. Of the latter we have three 
exainples from the Ucayali River, Peru, which correspond 
exactly with Felder’s figure. 
As Ihave just heard that Dr. Staudinger, of Dresden, is 
interesting himself in the study of this genus, I have named 
the preceding very distinct species in honour of him, 
XLI.—Cicadide from the Malay Archipelago.

Cicada operculissima, sp. n. 
Head ochraceous ; two spots on front and a broad fascia

and lateral margins pale ochraceous; a central fascia and
