Genus ORYXA.

Type, 0. tvimcata, Linn. 



Distribution. Oriental and Malayan Regions. 



This genus has been founded by Dr. Melichar for the reception 

 of the species described by Linnaeus as Fulgora truncata. There 

 is, however, some doubt as to the identity of this species, aod 

 Melichar has selected some Bornean specimens as representing it. 

 On the other hand, certain specimens from North Bengal are placed 

 under the specific name of Linnaeus in the British Museum, one 

 of which I have figured. Either of these may be correctly identified, 

 01% on the contrary, neither may represent it. As it is given as 

 the type of the genus Orya-a, and there is so much difficulty as to 

 its identification, I have only drawn attention to the genus, and 

 have not attempted its diagnosis.
