surface of 1-7, or even 1-10, pale yellow except the sternites of all and the apex of 3-7, which are 
blackish. Hind margin of segment 10 denticulated and with a shallow median excision, 
Superior abdominal appendages half, or less thin half, as long as segment 10, bent downward and inward. 
at a right angle as seen in most dried specimens, but when extended each appendage is more than half 
as long as 10, is bifid for two-thirds its own length, the upper and lower branches of subequal length and 
thickness (profile view), apices of the branches slightly curved toward each other, interval between the 
two branches subequal to or a little greater than the thickness of either branch; tip of lower branch 
ending in two small points or teeth. Inferior appendages slightly longer than the superiors, pale brown. 
Legs pale yellow, knees blackish, superior surface of first tibiee, two rather indistinct transverse fascis on all 
of the femora, and in some also on each of the other tibie, subfuscous; femora with an interrupted 
blackish superior stripe becoming continuous and darker with age. 
Wings hyaline, 9-11 postcubitals (most frequently 10, 662 “/o) on the front wings, 8-10 (most frequently 8, 
50 °/,) on the hind. 
Dimensions.—Abdomen 26:5-27°5, hind wing 16-17 mm. 9 unknown.

The additional figures will make clearer one of the differences between this and the 
other two species. | 
PROTONEURA (p. 140). 
Two new species necessitate the following modifications of the Key on page 140 :—- 
The clause “superior sector of the triangle ending a little beyond the cross-vein descending from 
the nodus” is to be taken out of the characters of division I. and made subdivision 1 of I., to 
include peramans, cupida, amatoria, sp. n., aurantiaca, and cara. 
Change CC to CCC, and insert a new CC as follows :— 
CC. Thoracic dorsum predominantly black, an orange antehumeral stripe, 
one-tenth to one-sixth as wide as the mid-dorsal black, reaching 
upward three-fifths’ to three-fourths’ way toward the base of the 
front wing (¢),or a yellow posthumeral line ( ? ), mid-dorsal thoracic 
carina orange or yellow; abdominal segments 3-6 of ¢ chiefly orange- 
red, black at apices and along sides; ¢ not distinguishable from that 
of cupida if the latter has been correctly identified. . . ~ « 2a. amatoria. 
(Cupida 3 has the blue antehumeral stripe one-half to one-third as wide as the black mid-dorsal 
stripe and reaching upward to the front wing base, the mid-dorsal thoracic carina black, abdominal 
segments 3-6 black with a narrow transverse basal blue ring. Aurantiaca ¢ has the orange- 
yellow antehumeral stripe wider than the mid-dorsal black, reaching upward to the front wing 
base, mid-dorsal thoracic carina black, 3 chiefly orange, 4-6 black with a very narrow transverse 
basal pale ring.) 
Between BB and II. insert subdivision 2 of I. as follows :— 
2. Superior sector of the triangle ending af the cross-vein descending from 
the nodus ; nodal sector on the hind wings arising nearest the fourth 
postcubital, thoracic dorsum chiefly pale blue (3') or metallic green (2),
