GONOMETINAE. By Dr. C. Aurivillius. 
*. The basal lobe and the basal cell of the hindwing are abnormally large, the former, if the wings 
are expanded, almost reaching the costal margin of the forewing, the latter often being larger 
than the discal cell with a strongly curved anterior margin. Eyes hairy. 
7. Pseudometa. 
**. The basal lobe and the basal cell of the hindwing are of a normal size, 
f. Vein 9 of fore wing terminates into the distal margin. 
/V. Erons with a longitudinal ridge which is more or less raised in the centre. Basal cell 
of hindwing with an accessory vein. 3. Gonometa . 
/V/V. Erons not armed. Basal cell of hindwing without an accessory vein *). 
1. Eyes bare. Forewing without transverse lines. 5. Grammodora. 
2. Eyes hairy. Forewing with transverse lines. 6. Anadiasa. 
ff. Vein 9 of of forewing terminates into the apex or costal margin. 
o. Fore wing short with a rounded apex; its anal margin is as long as, or longer than the 
distal margin. 
§. Veins 6 and 7 of fore wing rise separately from the apex of the dical cell. Eyes 
hairy. 8. Dipluriella. 
§§. Veins 6 and 7 of fore wings forked. 
1. Basal cell of hindwing with an accessory vein. Eyes hairy.

2. Basal cell of hindwing without accessory veins. 
a. Eyes hairy. 10. Pseudolyra. 
b. Eyes bare or only partly very finely hairy. 11. Lerodes. 
oo. Forewing elongate with a distinct apex. 
—. Basal cell of hindwing closed by a short cross-vein, but with a distinct accessory 
vein. Eyes hairy. 13. Napta. 
-. The terminal vein of the basal cell of the hindwirig is of the usual length. 
§. Vein 8 of fore wing from the pedicle of 6 and 7, rarely from 7. 
1. Basal cell of hindwing without accessory veins. 
a. The pedicle of the veins 9 and 10 of the forewing is much longer than 
the veins themselves. 4. Hypotrabala. 
b. The pedicle of the veins 9 and 10 of the fore wing is shorter than the 
veins themselves. 20. Pachymetana. 
2. Basal cell of hindwing with 1 to 3 distinct accessory veins, 
a. Basal cell of hindwing with but one accessory vein. 
17. Henometa. 
b. Basal cell of hindwing at least with two accessory veins. 
14. Libethra. . 
15. Borocera. 
16. Gastromega. 
§§. Vein 8 of forewing rises separately from the discal cell. Veins 9 and 10 of 
fore wing generally as long as, or longer than their pedicle. 
1. Basal cell of hindwing with a strong accessory vein. Eyes bare. 
18. Pachymeta. 
2. Basal cell of hindwing without accessory veins. 
a. Eyes bare. 
a'. Forewing feebly undulating. Abdomen with light transverse bands. 
— ^ Antennae at the base only serrate-dentate. 
19. Pachymetoides. 
b'. Fore wing with entire margins. Abdomen without bands. - 
Antennae with moderately long pinnae. 22. Leptometa. 
b. Eyes hairy. 
*) The precostal vein rising from the base of the wing is not to be regarded as-an accessory vein.
