the discocellulars are atrophied—the upper one meets the subcostal a little beyond 
the first branch, the lower one joins the median a little beyond the second branch ; the 
costal and median sides of the cell are subequal. 
The front legs of the male of Mf. phareus are slender, the trochanter is inserted before 
the middle of the coxa, femur < 3 coxa, tibia = 3 coxa, tarsus = tibia. The front legs of 
the female (I. hedemanni) have the second and fifth tarsal joints about equal, the 
latter having a strong setose pad on the under surface ; the fourth joint is the shortest, 
and the first, second, third, and fourth terminate beneath with two strong spines. The 
terminal joint of the palpi is very small and oval, <4 the middle joint, which is nearly 
uniform in width throughout, the basal joint > $ middle joint. Antenne have thirty- 
nine joints, the terminal thirteen forming a moderate club. 
The male organs are very similar to those of Cricosoma, so far as regards the tegumen. 
‘The harpagones are subtriangular in shape, and have an irregular outer edge, the upper 
portion of which, as well as the upper edge, is setose. The penis in general form is 
like that of Cricosoma, and it also has two or three series of strong dentate papille 
which may or may not be capable of extrusion. There is a curved strap connecting 
the penis with the harpagones as in many genera of the Erycinid, but which is absent 
in Cricosoma. There is no central spine between the harpagones as in that genus. The 
‘bursa copulatrix of M. hedemanni has a chitinous spine, two being visible in M, leucopus 
and none in Cricosoma. 
In other respects the structure of M. leucopus is quite similar to that of C. hedemanni.

Mesene ignicauda, Godm. & Salv. P. Z. 8. 1878, p. 363°. 
Alis nigris, posticis macula in margine interno et abdomine rubra; subtus obscure fuscis, maculis nigris griseo 
marginatis dense notatis. 
Q mari similis, sed macula rubra posticarum fere ad finem cellule anticarum producta; subtus macula 
rubra anticarum ut supra, abdomine obscuro. 
Hab. Panama, Chiriqui (Ridde), Bugaba (Champion), Veraguas (Arcé*). 
This species is allied to M. wrope of the Amazons valley, but the male differs in 
having a red abdomen, and the female in the red bands of the primaries not crossing 
the wings. 
Mr. Champion found it in the low forest region west of Bugaba. 
6. Wings of male black beneath, sexes dissimilar. 
2. Mesene phenicura, sp. n. 
Alis saturate fuscis, lineis obscuris indistincte transfasciatis, abdominis apice rubro; subtus saturate fuscis, 
immaculatis.
