MESENOPSIS.—SYMMACHIA. 415 
Alis nigris, ambabus fascia lata longitudinali flava ; subtus omnino ut supra, posticarum angulo anali flavido ; 
fronte, palpis, tectricibus alarum, cruribus anticis et abdominis lateribus flavis. 
© mari similis fascia flava latiore et pallidiore. 
Hab. Nicaragua, Chontales (Belt 12, Janson). 
Belt obtained many specimens of this species, and others were taken by Janson. 
In shape and colour it closely resembles Plavinia leta, a moth found in the same 
districts (Druce, Biol. Centr.-Am. Lep.-Het. i. p. 150). 
2. Mesenopsis melanochlora. (Limnas melanochlorus, Tab. XLI. fig. 5.) 
Limnas melanochlora, Godm. & Salv. P. Z. 8. 1878, p, 362°. 
L. bryaxi similis, fascia alarum angustiore et magis aurautia, et lateribus suis fere parallelibus distinguenda. 
Hab. Nicaracua, Chontales (Belt); Panama, Chiriqui (Ridbe'), Bugaba (Champion). 
In its style of coloration this species closely resembles LZ. bryaxis, but we have no 
doubt that it is really distinct. The yellow longitudinal bands of the wings are of 
nearly equal width throughout, instead of being subtriangular, and their colour is 
decidedly richer. 
It is a much rarer species than ZL. bryaxis—three specimens only, one from Chontales 
and two from Chiriqui, being all we have seen. 
In the latter country Mr. Champion found it in the forest region of the low country 
west of Bugaba. 
Josia ligata, a moth found at Bugaba, is very like this species in size and colour 
(Druce, Biol. Centr.-Am. Lep.-Het. i. p. 148). 
6". Antenne with white rings or spots *. 
SYMMACHIA. 
Symmachia, Hiibner, Verz. bek. Schmett. pp. 25, 26 (1816) ; Westwood, Gen. Diurn. Lep. p. 444 
(1851). 
After removing the section of this genus the wings of which are of a metallic green, 
and for which we have revived Hiibner’s name Caria, there remain about twenty-five 
species of true Symmachia, of which nine are found within our limits; of these, only 
three also occur in South America, leaving six peculiar. No less than eight species 
occur in Nicaragua; this is perhaps due to the great attention paid to them by Belt, 
with whom the genus was a special favourite. 
The primaries in S. threissa have the costa waved ; the subcostal nervure emits two 
branches before the end of the cell and one after it; the discocellulars are atrophied ; 
the middle meets the subcostal at nearly the same point as the lower radial (S. menetas 
has a very short upper discocellular), the lower the median some way beyond the 
* This division includes the following South-American genera :—Stseme, Rhicdina, Amarynthis, Zelotea, 
Imelda, and Dysmathia.
