and intermediate tarsi, and the inner margin of the opercula, 

 blackish. Abdomen pale castaneous, with the base narrowly 

 black, enclosing two small ochraceous spots. 



Tegmina and wings pale hyaline, the venation castaneous. 

 Tegmina with the costal membrane and basal cell pale casta- 

 neous ; the transverse veins at the bases of the second and 

 third apical areas narrowly infuscated, and a series of small 

 and somewhat indistinct fuscous marginal spots on the apices 

 of the longitudinal veins to the apical areas. Wings with the 

 margins of the claval areas infuscated. 



The face is very globose ; the opercula do not meet 

 centrally ; the rostrum reaches the posterior coxfe.

Hah. Australia (no precise locality). 



This species is allied to P. argentata, Germ., from which 

 it ditfers by the shape and colour of the opercula, the more 

 globose face, the different colour-markings, &c. 



I long possessed an unlocalized female specimen of this 

 species, and have lately acquired a male example from 

 Australia (no definite locality), which has enabled me to 

 describe it. 



Cicada extrema, sp. n, 



^. Head and thorax brownish ochraceous. Pronotum 

 with the lateral and posterior margins pale ochraceous. 

 Abdomen above castaneous, the posterior segmental margins 

 paler in hue ; apical half of the last segment and the anal 

 appendage ochraceous ; tympanal coverings obscure ochra- 

 ceous. Head beneath and sternum brownish ochraceous ; 

 the face, space between face and eyes, lateral margins of 

 prosternum, legs, and opercula, pale ochraceous; femora and 

 tibia? streaked with castaneous. Abdomen beneath casta- 

 neous, the apex pale ochraceous as above. 



Tegmina and wings pale hyaline, the venation fuscous, 

 ochraceous at basal area ; tegmina with the costal membrane 

 and upper part of basal cell ochraceous. 



The face is very globose, centrally sulcated (excepting at 

 base), and obliquely striated ; the rostrum reaches the inter- 

 mediate coxEe; the opercula are short, not extending beyond 

 the basal segment, are convexly rounded, and overlap at their 

 inner margins. 



$ . Head and thorax above pale greenish ochraceous and 

 unicolorous.
