margin of the cell by a cross-vein. 65. Hypselolopha 
— Both marks united not present.74. 
74. Posterior angle of cell of hindwing projects distally by % or % of the anterior margin 
of the cell beyond the anterior angle.78. 
— Posterior angle of the cell of hindwing projects little.75. 
75. 6 + 7 of hindwing on a very long stalk which is at least as long as the nervules 71. Contkeyla 
— 6 + 7 of hind wing on a shorter stalk.76. 
76. Antennae of <$ pectinated to the ends, posterior angle of the cell of the forewing 
slightly projecting.77. 
— Antennae of only basally pectinated, anterior angle of the cell of forewing pro¬ 
jecting . 74. Setora 
77. Antennae of $ bipectinated, 7 from the same place or on a short stalk with 8 + 9 
(cf. also Birthamula) . 76. Thosea p. p. 
— Antennae of $ only with one row of pectinations, 7 of forewing on a long stalk with 
8 + 9. 72. Iragoides p. p. 
78. Vein 8 of hindwing connected with the anterior margin of the cell by a cross-vein 
(cf. Aw+ca-group). 70. Comana 
— Vein 8 of hindwing anastomosing with the cell.79. 
79. Vein 11 of forewing arises far basad to 2, antennae of <$ with one row of pectinations 73. Ecnomoctena 
— Vein 11 of fore wing arises opposite or basad to 2, antennae of <$ bipectinate . . 76. Tliosea 
80. Antennae of <$ with one row of pectinations (but if the wings are long and narrow, 
cf. Belippa!) .77. 
— Antennae of <$ bipectinate or plain. 81. 
81. Veins 7 and 10 of forewing separated from the stalk of 8 + 9.82. 
— Only one of the two veins is separated from the stalk of 8 + 9 on the forewing, the 
other one arises with it from the same place or stalked.86. 
82. Vein 8 of hindwing connected with the anterior margin of the cell at +, % or behind 
its centre.84. 
— Vein 8 of hindwing connected with the cell near the base.83. 
83. Vein 11 of forewing arises oj+osite 2. 77. Natada 
— Vein 11 of forewing arises basad to 2.78. 
84. Vein 2 of fore wing arises distad to the centre of the distance 10—11, palpi upcurved 84. Darna 
— Vein 2 of forewing arises basad to the centre of the distance 10—11, palpi porrect 85. 
85. Cross-vein between 8 and the cell of the hindwing in the centre, antennae of $ with 
bare ends. 86. Limacontia 
— Cross-vein of hindwing between 8 and the anterior margin of the cell at % of this 
margin, antennae of pectinated to the ends. 85. Oxyplax 
86. Vein 10 of fore wing stalked with the stalk of 8 + 9 (but if 4 + 5 of fore wing 
from the same place or stalked, cf. Darna) .87. 
— Vein 10 of fore wing separated from the stalk of 8+9.89. 
87. Antennae of $ pectinated.8. 
— Antennae of $ }:>lain, often thickened and flattened. 82. MacropledTina 
88. Pectinations of $ antennae shortening not only towards the ends, but also basally; 
8 of hindwing anastomosing with the anterior margin of the cell. 81. Semyra 
— Pectinations of antennae long, shorter towards the ends, 8 of hindwing connected 
with the anterior margin of the cell by a cross-vein. 79. Macroplectra
