belonging to the Homopterous family Cicadide. 641 
The head, including eyes, is narrower than base of pro- 
notum, and but little wider than mesonotum. The 
rostrum about reaches the apex of the first abdominal 
segment. The opercula, which almost reach the apex of 
the fourth abdominal segment, are situated on lateral 
side of abdomen, much wider apart at base than at apex. 
They are concavely narrowed on each side near base, 
and are then widened and convex on each side to apex, 
which is broad and rounded, the extreme apex being on 
outer margin. ‘The face is swollen, with a curved black 
fascia at base, and a central longitudinal sulcation ; it is 
profoundly transversely striated, the interstices being 
very broad. Long. 39mm. Exp. tegm. 96 mm.

This species is allied to C. doryca, Boisd., but the 
body is much broader, the tegmina unspotted, and the 
shape of the opercula more like those of C. abdulla, Dist. 
Cosmopsaltria operculissima, 0. 8. 
3. Body above castaneous. Head with lateral 
margins of front, lateral margins of vertex, area of 
ocelli, and an irregular spot between ocelli and eyes, 
black. Pronotum with two central, longitudinal, slightly 
curved black, fasciz, concave externally, a small curved 
fascia on each side of disk, and the oblique striew also 
black. Mesonotum very dark castaneous, with two 
obconical spots on anterior margin, denoted by black 
margins, and with some very indistinct darker shadings 
on lateral sides of disk. Cruciform elevation at base 
pale castaneous. Abdomen somewhat darker on disk 
and near lateral margins. Body beneath much paler, 
and clothed with ochraceous pubescence; face cas- 
taneous, with the centre black; opercula ochraceous, 
with a broad subapical fuscous band, both above and 
below. ‘T'egmina and wings pale hyaline; veins, costal 
membrane, basal area, and claval margin of tegmina, 
castaneous. Abdomen very short, less than length from 
front of head to base of mesonotum; head broad, in- 
cluding eyes, equal to width of pronotum at base; 
opercula very large, about reaching apex of abdomen, 
and abutting on each side of apical lateral margins; 
they are narrow, and situated wide apart at base, nar- 
rowed and concave on each side about basal abdominal 
segment, and then broadly widened and convex on each
