IJah. Australia, Swan River. Coll. Dist. 



This somewhat large species of Cicada is allied to C. inter- 

 secta, Walk., and like that species has the pale apex to the 

 abdomen ; but C. extrema may be at once recognized by the 

 more robust and less symmetrical body, the head and thorax 

 being relatively wider, the unspotted head and thorax, the 

 longer second apical area to the tegmina, &c. 



Cicada madagascariensis^ sp. n. 



^ . Body above dull ochraceous. Head with the margins 

 of front, fasciffi to lateral areas of vertex, and the area of the 

 ocelli, black. Pronotum with a central longitudinal fascia 

 margined with black (these black edges sometimes obsolete). 

 Mesonotum with four obconical dull castaneous spots, the 

 central pair shortest and somewhat fused, a similarly coloured 

 spot in front of the basal cruciform elevation. Body beneath 

 and legs pale ochraceous ; central area of face and a fascia 

 between base of face and eyes black. 



Tegmina and wings pale greyish, semihyaline and talc- 

 like, the venation ochraceous, inclining to fuscous towards 

 apical areas ; tegmina with the costal membrane ochraceous, 

 the transverse veins at the bases of the second and third 

 apical areas narrowly infuscated, and a submarginal series of 

 small fuscous spots placed on the longitudinal veins to the 

 apical areas. 



The eyes are large, prominent, and subsessile ; the ros- 

 trum reaches the posterior coxa3 ; the opercula are about the 

 length of the posterior tibite, oblong, just or almost meeting 

 at their inner basal margins, their apices convexly rounded 

 but not extending beyond the basal abdominal segment.

Hah, North Madagascar. 



A very small species of the genus ; its principal charac- 

 teristics are its pale greyish semihyaline tegmina, with the 

 darker venation and submarginal spots, the large and promi- 

 nent eyes, and the well-developed opercula. 



It is allied to C. maculigena, Sign., but differs from the 

 description of that species by the smaller expansion of the 

 tegmina, with the small submarginal fuscous spots to same ; 

 the markings of the pro- and mesonotum appear to be also 

 altogether different.
