T. virgilio similis, sed posticis ad angulum analem multo magis productis ; subtus saturatius rufescentioribus, fascia 
obscura communi ab angulo anticarum apicali ad medium marginis interni posticarum transeunte, macula 
in medio cellularum, altera ad finem earum et una ad medium posticarum coste albidis, ocellis binis ad

—COLOMBIA. 
T. basilea is the largest member of the genus. It was described from a female 
specimen sent us by M‘Leannan from the Isthmus of Panama. To these we have 
added three males, one from each of the localities mentioned above. 
c. Wings beneath brown, the base of the primaries yellow.

Theope decorata, Godm. and Salv. P. Z. S. 1878, p. 369°. 
Anticis et posticarum marginibus nigris, macula in margine interno angulum analem prope et ad basin sparsim 
atomatis, et area posticarum interna cyanea; subtus obscure fuscis, apicibus dilutioribus, dimidio basali 
costee anticarum et posticis ad basin ochraceis, fascia arcuata costam partim occupante ad apicem curvata, 
certa luce purpurescenti-cerulea. 
Hab. Nicaracua, Chontales (Belz *). 
T. decorata belongs to a small section of the genus containing T. janus and T. discus 
of Bates, the wings of which have a blue blush beneath, and some of them, as in the 
present case, being yellow at the base of one or both wings. Our description is based 
upon a single specimen which formed part of Belt’s Chontales collection. 
C. Subcostal nervure of primaries with two branches only. 
ISAPIS. 
Isapis, Westwood, Gen. Diurn. Lep. p. 465 (1851). 
This genus either consists of one or perhaps two variable species, or when our 
materials are more complete it may be found capable of further subdivision. It is 
found throughout Tropical America from Guatemala to Brazil. 
The subcostal nervure of the primaries in J. agyrtus emits one branch at the end of 
the cell and one beyond it, the upper radial meets the subcostal some way beyond the 
end of the cell, the middle discocellular is short but perfect, it meets the subcostal 
nearly at a right angle, the lower discocellular is curved and atrophied in the middle
