836 On Cicadidee from Indo-China. 
joint of the antenna is dark. The sides of the pronotum 
and elytra are also tinged with red and some specimens 
(probably immature) are entirely red. 
The tibiza and tarsi are very slender, as in allied forms, 
and the claws also are slender and strongly curved, with 
large basal lobes, from the sides of which the claws are 
separated only by narrow intervals. The antennz are also 
slender, but the two first joints are a little thicker, the 3rd 
rather longer than those that follow, and the three forming 
the club very loosely attached to one another. 
XLVI.—Cicadidee from Indo-China. 
By W. L. Distant. 
In my last enumeration of the species belonging to the 
Homopterous family Cicadide received from Indo-China by 
the efforts of Mons. R. Vitalis de Salvaza (Ann. & Mag. Nat. 
Hist. (9) iii. p. 43, 1919) no fewer than seventy-six species 
had been recorded. I am now enabled, by the continued 
assistance of the same entomologist, to add three more species 
to the list, thus bringing up the total to seventy-nine. 
Mogannia aliena, sp. n.
