OtnuiO'tissiis Fieb. 



Dr. ^lelichar* has qnestioned the status of Ommatlssus 

 lofoneiisis JMnir and 0. chinsnnensis Mnir from China, partly 

 on aeeount of the geographical distribution ; the only other spe- 

 cies of the genus being found in Andalusia, Spain. I have not 

 seen specimens of 0. binotatus Fieb., but the two Chinese spe- 

 cies agree with Fieber's figures and descriptions so closely that 

 I cannot change my opinion. In the Chinese species the me- 

 dian vein forks at the cross-veins instead of near the apex ; the 

 face is slightly broader; in 0. chin.mnensis Mnir the clypeus in 

 profile is slightly more arcuate and in (). lofouciisls Mnir still 

 more so, but these slight differences are not sufficient to create 

 a new genus on. Fhe male genitalia separate the three species. 



j\ roiiniiafissus Mnir. 



I can find no good charactei's u])on which to separate Staco- 

 f aides Distant fntui this genus. I jdaced this, along with 

 Onunalissiis Fieb. among the Cixiids as the latter holds that 

 ))osition in Oshanin's Catalogue. They both ])ossess the hair- 

 line dividing off the ])osteri()i' angle of the mesonotum.
