20. Genus: f B EfiagB«>j>iis Fldr. 
In the forewing the 1st cubitus is not forked, nor in the hindwing, where it rises distantly separated 
from the 3rd median. Wings mostly very hyaline. 
Ph. cyanomelas Fldr. (70 d). Forewing as clear as glass, with a black costal margin, distal margin 
and hind-margin and 2 transverse bands and all the veins being black. Hindwing hyaline, veins, costal 
margin and distal margin broadly black. All the wings iridescent blue. Costa Rica, Colombia, Ecuador. 
Ph. taxila Drc. is similar to the preceding, but with only one transverse band across the forewing. 
Expanse 45 mm. Colombia. 
Ph. faiidica Dgn. Wings black with a blue lustre, the forewing with a whitish hyaline transverse 
band distally to the cell from the subcosta to the 1st cubitus. Expanse 39 mm. Peru, Venezuela. 
Ph. vitrina Drc. (70 c). Forewing blackish-brown, with a slight blue reflection, with a hyaline, black- 
veined triangle at the base between the anterior edge of the cell and the axillaris as far as 4 / s of the wing, 
and a hyaline, partly white-scaled discal transverse band and some subapical spots. Hindwing hyaline, costal 
margin, distal margin and veins black. Panama, Costa Rica. 
Ph. milforrhabda Pvt. Wings narrower, forewing black with a brownish tinge; a slanting red band 
of 2 mm width extends from the centre of the costal margin to the 2nd cubitus right before the margin, 
the 1st radius, radial ramus and 2nd cubitus black, a bent row of 3 hyaline dots between the 5th radial and 
3rd median. Hindwing black with a brown tinge. Peru: Chanchamayo. It copies Actinote erinome Fldr , (Yol. 
V. pi. SI a) and Eresia Castilla Fldr. (Yol. V. pi. 92 e). 
21. Genus: Autliyiila Warr. 
Corresponding with Phdnoptis, but in the forewing the 1st cubitus is very near to the 3rd median. 
Au. obliquaria Warr. (69 k). Wings hyaline, veins and margins blackish-brown. In the forewdng the 
hind-margin and subcostal stripe as far as the centre are red-brown. The hind-margin is opposite the latter 
half of the 2nd cubitus broader. From the costa a black band, enclosing the cross-vein with which it termi¬ 
nates posteriorly, and another from % of the costal margin to the distal margin at the 3rd median, wdiere 
it is widened. Peru. 
22. Genus: Monocreagra Fldr. (Tanaostyla Warr.). 
In the forewing the 3rd radial branch rises before the 5th. the cell is of normal size, the wings are 
hyaline. Antennae ciliated, in the $ in tufts. 
M. orthyades Drc. (70 cl). Wings hyaline, margins and all the veins blackish, particularly broad the 
cross-vein, 3rd median and 1st cubitus. Colombia. Ecuador. 
M. pheloides Fldr. (= dilucida Warr., conjunctiva Warr.) (70 d). Like the preceding, the hyaline space 
behind the cross-vein is white, the veins therein not darker. Expanse: $ 40 to 45 mm. Colombia, Bolivia. 
M. unimacula Warr. Like the preceding, perhaps the southern race of it, smaller (£ 35 to 40 mm), 
apical third of forewdng more extensively black, the white spot smaller. Bolivia, Peru. 
M. disconnexa Dgn. Forewing whitish hyaline, costal margin narrowly black, a spot in the last third 
of the cell and the distal margin broadly black, in the latter 3 white spots between the veins 2 to 6, vein 
5 remaining white. Hindwing whitish hyaline, apex and distal margin black. Expanse 25 mm. Colombia. 
23. Genus: Isosfyla Prt. 
Radial branches as in the preceding genus, 3rd median and 1st cubitus forked. antennae with long 
combs. 
I. zetila Bsd. (= nubila Schs.) (69 k). Greyish-hyaline wings, veins and margins darker, in the fore¬ 
wing a white transverse spot behind the cross-vein as far as the 1st cubitus, the 3rd m e cl i a n t h e r e i n 
w h i t e , some whitish subapical spots, and in the hindwing indistinct white submarginal spots. Guatemala, 
Costa Rica. 
1. erycinoides Fldr. (= ithomeina Btlr.) is similar to zetila, but the 3rd median in the forewdng is 
also black. Postdiscal spot smaller, 4 submarginal spots in the forewdng. Panama, Costa Rica. -—■ picata Warr. 
(69 k) has all the hyaline places of the wings in the B whitish, in the $ like in the B and $ of the type 
hyaline, with a slight blue iridescence. Colombia, Ecuador. •— In purefacta Prt. the cubitus and the base of 
its branches in the forewing are white, the hindwing is almost entirely white, with a narrow distal margin. 
South Ecuador.
