varieties. Comparing this with Signoretia it is to be noted 

 that the area corresponding to an outer subapical cell in that 

 genus, is here entirely confluent with the fourth apical cell. 



Genus ONUKIA Matsumura 

 Matsumura, Annot. Zool. Japan. 8 (1912) 44. 



Type, Onukia onukii Matsumura. 



Distant has redescribed this genus in the Tettigoniellidae 

 under the name of Apphia. 20 He does not mention the ocelli 

 or the peculiar structures connected therewith. The genus 

 Omaranus, immediately following Apphia, also belongs to the 

 Pythamidae, as the general structure and the position of the 

 antennae clearly indicate. Here again, neither the exact position 

 of ocelli nor the accompanying structures are described.

This well-marked species, the type of the genus, has a very 

 close general resemblance to Pythamus melichari except in the 

 median carina of vertex. 



The front, clypeus, and lorae are coarsely shagreened, the 

 genae are transversely wrinkled below the eye and longitudinally 

 wrinkled near the outer margin. The lateral portions of front
