PAROPIIME 

 {Megophthalmidse) 

 One has only to study Paropia and Stenocotis or Kyphocotis 

 (Plate 1, fig. 2) side by side to realize their close relationship 

 in essential structure. From my previous account of this sub- 

 family was omitted the genus Mesoparopia Matsumura, 10 de- 

 scribed as of this family, with two species, M. nitobei from 

 Formosa and M. fruhstorferi from Tonkin. 



ULOPID^E 



A reexamination of material in this family makes clear a 

 close relationship with Paropia and Stenocotis. The apparent 

 absence of ocelli is a character of little value. In related genera 

 ocelli may be very small and weak, and, in the confusion of 

 coarse pits over the ocellar area, rudiments of ocelli might easily 

 exist but be indistinguishable. It should not be stated that they 

 are "absent" until microscopical sections are made of the ocellar 

 area. The relationship of Ulopa and Paropia is evident from 

 the accompanying figure (Plate 1, fig. 3, b-e) which shows frontal 

 and lateral views of the side of the face in both of these genera. 



The examination of material of the genus Moonia Distant has 

 been made possible through the kindness of the director of the 

 Zoological Survey of India. This shows at once, what had been 

 suspected, that this genus is one of the Ulopidse and very closely 

 related to Ulopa, from which it differs most conspicuously in 

 the shorter vertex — a minor character. The structure of its face 

 shows that Mesargus Melichar 1X should be placed in this family. 

 Distant 12 notes its similarity to Moonia. Radhades, Sitades, and 

 Durgades of Distant show some superficial resemblance to 

 Moonia, but apparently belong near Nehela. Ulopa and Moonia 

 possess a character that is unique among jassoid insects ; namely, 

 strongly rounded genae, the sharp outer edge of which curves 

 mesad to the front above the lorse, the lower margin passing 

 beneath the lorse, leaving the latter with the outer border 

 apparently free, in facial view. These two genera correspond 

 in various other essentials. Daimachus Distant, placed in the 

 Ledridae, is Ulopa. Gubela, also placed in the Ledridae, is very 

 close to Ulopa. Sichaea Stal appears to be related to Ulopa.
