190 MR. "W, L. DISTANT ON THE CICADID^. [Apr. 17, 



rounded at apices. Abdomen above distinctly and longitudinally- 

 raised and carinate. Face very prominent, strongly compressed and 

 wedge-shaped, concavely narrowing on its apical half. Rostrum 

 reaching the intermediate coxae. Tegmina elongate; the costa very 

 slightly depressed immediately beyond base, and then slightly raised 

 and convex from about the apex of upper ulnar area ; the interior 

 ulnar area with the apex slightly but distinctly broader than base ; 

 the space between the apices of the postcostal vein and the postcostal 

 ulnar ramus ampliated, and the costal margin very finely hirsute ; 

 apical areas eight, the eighth broadest and shortest ; an additional 

 curved and rudimentary vein connecting the base of the second and 

 the apex of the fifth ulnar areas, this vein is distinct and perfect for a 

 short distance from the base of the second and into the third ulnar 

 areas, after which it is subobsolete ; basal area almost twice as long 

 as broad. 



My knowledge of this most interesting genus is confined to a 

 female specimen collected by Dr. A. B. Meyer in Celebes.

2 . Pale ochraceous or greenish ; ocelU castaneous ; mesonotum 

 with two central obconical dark spots, the bases of which rest on 

 anterior margin ; on each side of these is a much longer and more 

 acutely pointed spot, and a small round spot in front of each 

 anterior branch of the cruciform basal elevation, which is marked by 

 two central darker lines ; - abdomen above sparingly pilose, the 

 apical segmental margins paler. Body beneath and legs pale ochra- 

 ceous or greenish ; femora near apices, tibiae near bases and at apices, 

 and apices of tarsi fuscous. Rostrum with the apex pitchy. Teg- 

 mina and wings pale hyaline, the first minutely spotted along all 

 the veins and more or less across its apical half.

S . Head and pronotum pale ochraceous, the last with two central 

 longitudinal pale brownish lines, the posterior margin greenish with 

 its inner border and the lateral margins pale brownish. Mesonotum 

 pale brownish, the lateral margins and cruciform elevation ochraceous. 

 Abdomen warm ochraceous, the disk brownish and the base of the 

 last segment broadly blackish. Body beneath and legs ochraceous. 

 Tegmina and wings pale hyaline. Tegmina with the costal mem- 

 brane and basal half of venation greenish, remaining venation and 

 claval area brownish. Wings with the venation brownish, the 

 claval area more or less suffused with the same colour. 



Rostrum reaching posterior cosse, its apex dark fuscous. The 

 face is moderately broad, the central sulcation deep, and the trans- 

 verse striations distinct. Anterior femora armed with three strong 

 spines, the one near apex smallest. Posterior femora with a few
