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. 



Tlie tibial and tarsi are very slender, as iu 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 antcnnre 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. — Cicadidge/rowi Itido-C/iina. 

 By W. L. Distant. 



In my last enumeration of the species belonginfr to the 

 Homopterous family Cicadidaj received from Indo-China by 

 the efforts of Mons. R. Vitalis de 8alvaza (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.
