Genus FGYors Gncrlii. 



U. occldcnfaJis sp. iiov. 



This species is congeneric with ['. litiirifrons (Walk.), the tegniina 

 are broadly tectiform, the median frontal carina double to near apex 

 and the first joint of antennae slightly shorter than the second. 



Ochraccous-bnff with lirown markings as follows : carinae of head and 

 thorax, small spots alongside of median carinae of face, spreading across 

 to sides at apex, two rings on apical antennal joint, bands on front 

 and middle femora and tibiae, a longitudinal mark on hind femora, lat- 

 eral areas of pro- and mesonotum, on the apical abdominal segment, base 

 of pygophor and the anal segment. Tegmina hyaline, veins dark, broken 

 with light patches, granules minute, bearing small hairs concolorous with 

 vein. 



Genitalia of the l\s;\'flfs type; anal segment dome-shape with anus at 

 top, apical edge slightly emarginate, ventral edge of pygophor quadrately 

 emarginate, a small angular emargination in the medio-ventral line; styles 

 sub-cylindrical, the curve of apical two-thirds slight. 



Length 4.5 nnn. ; tegmen 5.5 mm. 



2 Similar to male. Anal segment small, about as long as broad: 



ovipositor with more than one-third extending beyond pygophor; lateral 

 plates reaching beyond middle of pygophor. 



Length 5 mm. ; tegmen 5.7 mm.

Genus PcJSTAXA Muir. 

 P. piierforiceitsis sp. nov. 



$ Width of vertex more than double the length along the middle 

 line, projecting very slightly beyond eyes, base concave, apex convex, 

 the Y-shape carina obscure, the fork forming a small areola at apex; 

 face slightly broader than long, subcircular except at apex, face and 

 clypeus medially and laterally carinate, carinae obscure; antennae not 

 rt'aching to middle of clypeus, second joint 2.5 times the length of first, 

 first subsagittate, second subovate, considerably flattened, with large sense 

 organs on dorso-apical portion, both joints with stout hairs, arista apical. 

 Pronotum slightly longer than vertex, hind margin shallowly and roundly 

 emaiginate, tricarinate, the lateral carinae curving parallel with hind mar- 

 gin of Q>'es and do not reach the hind margin. Tegmina broad, slightly 

 decumbent beyond apex of abdomen, radius not touching media, cubitus 

 and media touching at base of first median sector. Hind tibiae with one 

 basal, one median, one subapical and five apical spines, hind tarsus two- 

 thirds the length of tibia, first joint slightly longer than the other two
