PERICOPINAE. By Dr. M. Hering. 
1. In the forewing all the veins are present. 
a. In the hindwing the 3rd median branch and 1st cubitus are not forked, 
a. In the hind wing the posterior angle of the cell is hardly produced. 
*. Margin of the hindwing before the anal angle with a concave indentation. 
Ambryllis. 
**. Margin of the hindwing everywhere convex. Daritis. 
(3. Posterior angle of the cell of the hindwing laciniformly produced. 
*. 3rd joint of the palpus at least one third as long as the second. 
o. 1st cubitus in the hindwing in the centre between the 2nd cubitus and 3rd median 
branch, posterior angle of the cell of the forewing very much produced. 
Xenosoma. 
oo. 1st cubitus in the hindwing nearer at the 3rd median branch, posterior angle of the 
cell of the forewing less produced. Thyrgis. 
**. 3rd joint of the palpus one fourth the length of the second at most. Composia. 
b. In the hindwing the 3rd median branch is forked with the 1st cubitus. 
a. In the forewing the 2nd cubitus is nearing the first, the distance between both being one 
half at most of the length of the posterior edge of the cell from the base to the 2nd cubitus. 
Gnophaela■. 
(3. 2nd cubitus farther towards the base, its distance from the 1st cubitus more than % of 
the basal portion of the posterior edge of the cell. 
Pseudophaloe. 
2. In the forewing one vein (the 3rd radial) is absent. Josiomorpha. 
II. In the forewing the 2nd to 5th radials are forked. 
1. 5th radial rising before the 2nd. 
a. In the hindwing the 2nd median branch is about in the centre between the 1st and 3rd median 
branches. Cyanohypsa. 
b. 2nd median branch nearing the 3rd. 
a. 1st radial in the forewing before the middle of the distance of the 1st and 2nd cubitus. 
*. 1st and 2nd cubitus in the forewing converging towards the margin. Ephestris. 
**. 1st and 2nd cubitus diverging at their rise. Isostola. 
(3. 1st radial in or behind the middle of the distance of the 1st and 2nd cubitus 
Calodesma. 
2. 2nd radial rising before the 5th. 
a. The 3rd joint of the palpus far less than a half of the second. Eucyane. 
b. The third joint of the palpus at least a third of the second. 
a. Third palpal joint little shorter than the second. Jo'siomorphoides. 
(3. Third palpal joint a half of the second at most. Sagaropsis. 
B. Hind tibiae with 1 pair of spurs. 
I. In the forewdng the 2nd radial is separate, or only anastomosing with the 3rd to 5th radials. 
1. In the forewing the 5th radial branch rises before the 3rd. 
a. In the hindwing the 3rd median branch is not forked with the 1st cubitus. 
a. Pinnae of the $ antennae shorter than the diameter of the shaft (the 2nd radial often 
anastomosing with the 3rd to 5th. Pericopis. 
(inch Chetone, Tkebrone, Sermyla, Taxila). 
[3. Pinnae of the $ antennae at least as long as the diameter of the shaft. 
*. 3rd palpal joint very much shorter than the second. Dysschema. 
**. 3rd palpal joint about half the length of the second. 
o. Distance of the 1st radial from the 2nd in the forewdng twice as long as that from 
the 2nd to 5th radials. Are. 
oo. Distance of the 1st radial from the 2nd about the same as that from the 2nd to 
5th radials, or shorter. Phaloe. 
b. In the hindwing the 3rd median branch is forked with the 1st cubitus. Ctenuchidia. 
2. In the forewdng the 3rd radial branch rises before the 5th. Phaloesia. 
II. In the forewing the 2nd to 5th radials are forked. 
1. In the hindwing the 3rd median branch is not forked with the 1st cubitus. 
a. In the forewdng the 2nd to 5th radials before the cell-angle, separated from the 1st median 
branch, in the hindwdng the distance from the 3rd median branch to the 1st cubitus is less 
than twice as long as the distance from the 2nd median branch to the 3rd. Hyalurga.
