S. paradoxaria Stcfr. (=^ mivificsLTia. Led.) (Q c). Forewing uniform dull green, beneath somewhat lighter paradoxa- 

 and more yellowish green. Hindwing above and beneath paler, almost whitish. From the similarly but more '*"' 

 brightly coloured Leptostegna teneraia, and indeed from all known species, the shape at once distinguishes it. 

 Only known from Greece and Sicily. 



33. Genus: I^eptoHteg'iia Chr. 



Face smooth, rounded. Palpus minute. Tongue developed. Antenna in cf dentate, with fascicles of 

 short cilia, in ? simple. Hindtibia with all spurs. Frenulum wanting. Forewing with areole single. Hindwing 

 with costal separate from the cell, connected beyond the middle by an oblique bar, which may be regarded 

 as the P' subcostal, usually absent, but here separating again from the costal near the apex, 2"'' subcostal 

 long-stalked with P' radial, discocellulars biangulate, 2"'' median present, running to anal angle, submedians 

 absent, the inner area of the wing being somewhat reduced. The only known species is Asiatic. 



L. tenerata Chr. (6 c). Forewing green, rather thinly scaled, with indistinct white antemedian, post- tmerata. 

 median and subterminal lines and very small white cell-dot. Hindwing white, becoming greenish in distal half. 

 Underside similar, hindwing slightly greener. Japan, Korea and E. Siberia. — asiatica Warr., from W. China asiatica. 

 and N. India, is on an average somewhat larger, the distal margin of the forewing more oblique, of the hind- 

 wing straighter in the middle, the forewing slightly more mixed with whitish, the white lines and dot more 

 sharply expressed, the lines more lunulate, hindwing also rather better marked. Possibly a distinct species. 



34. Genus: Ptygniatoplioi'a Gmphg. 



Face smooth. Palpus short, rough-scaled beneath. Antenna in both sexes simple. Hindtibia with 

 all spurs. Forewing with areole double. Hindwing in cf with costal area greatly expanded, inner-marginal 

 part specialized into a deep, hairy, furrowed fold, costal vein well separate from subcostal, connected by a bar 

 about the middle of the cell, which is short, 2°'^ subcostal short-stalked with P' radial, 2"^ radial closely 

 approximated to 3"*. 



This genus, first named Ptygmatophora by Gumppenberg, was renamed Bessophora by Meyrick 5 years 

 later. Only the type species is known, coming from Eastern Asia. 



Pt. staudingeri Chr. (6 b). Easily known by its bright golden orange ground colour and heavy black s, 

 spotting, rather recalling some of the Abraxas group of the Geometrinae. The size, shape and exact position 

 of the black spots varies slightly. Under surface like upper. Amur and Korea. 



35. Genus: Microloba Hmps. 



Face smooth. Palpus rather short, rough-scaled. Antenna in both sexes strongly pectinate. Hindtibia 

 with all spurs. Frenulum present. Forewing with areole single. Hindwing relatively small, especially in the 

 cf; costal in both sexes anastomosing with subcostal to beyond the middle of the cell; 2"'^ subcostal in cf 

 remote from 1^' radial, P' discocellular almost vertical, 2°'^ radial from near 3'''^, inner-marginal area reduced, 

 folded; ? neuration normal, 2"'' subcostal short-stalked. 



Of this genus also only one species is known, inhabiting Eastern Asia. 



M. bella Btlr. (= eburneata Chr.) (6d). Easily recognizable from our figure. Underside similar to bella. 

 upper, but the proximal two-thirds of forewing somewhat darkened and more strongly marked than above. 

 Japan, Korea, E. Siberia and China. 



36. Genus: Brabira Moore. 



Face smooth. Palpus longish, rough-scaled. Antenna in cf bipectinate, in ? simple. Hindtibia with 

 all spurs. Forewing ample; areole double. Hindwing small, the distal margin excised between the 2"'' sub- 

 costal and 2"'' (or 3'^) radial, the inner margin in the cf with a large fold at the base, costal anastomosing
