MESOSEMTIA. 381 
It is a common species in the low-lying forests of Guatemala on both sides of the 
mountain chain up to an elevation of about 3000 feet. It frequents the forest, hiding 
beneath leaves. 
6. Both wings obscure blue, covered with dark transverse bands. 
3. Mesosemia hesperina. (Tab. XXXVIII. figg. 133,142.) 
_Mesosemia hesperina, Butl. Trans. Ent. Soc. 1874, p. 430°. 
Alis lavandulo-ceruleis, anticis ocello nigro albo pupillato ad cellule finem, lineis sex transversis nigris, quatuor 
(margine externo incluso) externis plus minusve margine externo subparallelibus, duabus internis 
obsoletis per cellulam transeuntibus ; posticis lineis sex nigris transfasciatis; subtus griseo-fuscis, lineis 
fuscis ut supra transfasciatis, anticis ocello ut supra sed fulvo ciliato et juxta eum irregulariter fusco 
notatis ; posticis ocello parvo ad cellule finem. 
2 alis fuscis, obscure fusco frequenter transfasciatis, et prope ocellum anticarum fulvo notatis. 
Hab. Nicaragua, Chontales (Belt 1); Panama, Bugaba (Champion, Arcé). 
We have Mr. Butler’s type specimen of this species before us, and several other 
males from Chontales, all collected by the late Mr. Belt. We now trace it to the 
neighbourhood of Chiriqui, where Mr. Champion also obtained a female. 
As Mr. Butler remarks, VM. hesperina is allied to the Brazilian J. veneris, but it has 
a still closer relative in a species from the west coast of Colombia*; and IM. calypso, 
Bates, is also nearly allied. 
c. Discal area of secondaries blue, without dark bands.

Alis fusco-nigris, anticis ocello nigro, ceruleo-albo pupillato et pallide fusco ciliato ad cellule finem ; posticis

anticarum tripupillato et fulvo ciliato, posticis ocello altero simili, fascia communi ultracellulari angusta. 
Q mari similis, sed major et alis omnino dilutioribus, anticis parte distali saturatiore et linea submarginali 
pallida bisecta, linea altera obscura transversa ultra cellulam. 
Hab. Nicaracua, Chontales (Belt, Janson) ; Panama, Veraguas (Arcé'). 
This beautiful species was described by Mr. Bates from specimens sent us by our 
collector Arcé from the neighbourhood of Veraguas. It has since been found at 
Chontales by the late Mr. Belt. Curiously enough it is not known in any of the 
* Mesosemia thetys, sp. n. 
M. hesperine affinis, sed major, colore ceruleo magis obscuro et paulo viridescentiore, plaga nigra infra ocellum 
anticarum et fasciis omnibus nigris latioribus distinguenda. 
Hab. Cotomsta, Rio San Juan (Trétsch).

We are indebted to Dr. Staudinger for the possession of two males of this species.
