2o6 HOMOPTERA 



198. GENUS ANTIALCIDAS DisTANT 



Antialcidas Distant, Rhynch. Notes 326 (1916). 



Characters : This genus is veiy close to the preceding and perhaps is not deserving of separate 

 generic rank. If the two genera are not distinct, then this genus is valid and Paniahun becomes a 

 synonym. The only important dilference between Pantaleon and Antialcidas is in the structure of the 

 suprahumerals which in the former are strongly toothed and in the latter are simple. This difference, 

 however, is conspicuous and noteworthy and seems to be constant, and we are therefore considering it 

 a satisfactory generic character. The other characters are very similar to those of PantaUon and may be 

 briefly listed as follows : Head subquadrate, broader than high; base arcuate; eyes ovate; ocelli 

 inconspicuous, a little farther from each other than from the eyes and situated above a hne drawn through 

 centers of eyes; clypeus extending for half its length below inferior margins of genae, tip rounded. 

 Pronotum convex with strong, simple suprahumerals ; metopidium vertical, broader than high; median 

 carina percurrent; humeral angles small, triangular and pointed; suprahumeral horns strong, triquerate, 

 extending outward and upward, as long or longer than the distance between their bases, tips sharp and 

 without teeth; posterior process elevated into a high, usually triangular dorsal node, much flattened 

 laterally and inclined to be foliaceous, tip suddenly acute and reaching just about to the tipsofthe 

 tegmina; scutellum narrowly exposed on each side. Tegmina semiopaque ; base narrowly coriaceous 

 and punctate; five apical and two discoidal cells; apical limbus narrow. Legs simple; femora 

 cylindrical; tibiae triquerate and finely spined; hind tarsi longest. 



Type iri/oliaceus Walker. 



Geographical distribution : Anlialcidas, like the preceding genus, is hmited in distribution to 

 Eastern Asia.

199. GenUS MAURYA DISTANT 



Maurya Distant, Rhynch. Notes 326 (1916). 



Characters : Medium-sized insects with cornute suprahumerals and a more or less elevated 

 flattened posterior process which does not show a high dorsal node. Head subquadrate, broader than 

 high; base arcuate; eyes globular; ocelli large, prominent, a little farther from each other than from 

 the eyes and situated somewhat above a line drawn through centers of e^^es ; inferior margins of genae 

 sinuate and sloping downward; clypeus extending for more than half its length below inferior margins 

 of genae, tip rounded. Pronotum convex with short, heavj', sharp suprahumerals; metopidium nearly 

 vertical, broader than high; median carina strongly percurrent; humeral angles heavy, triangular and 

 blunt; suprahumeral horns stout, triquerate, robust, extending outward and upward, not as long as the 

 distance between their bases, tips pointed; posterior process heavy, laminate, tectiform, tip acute and 

 just reaching the internal angles of the tegmina; scutellum narrowly exposed on each side. Tegmina
