LEUCOTHYRIS. 39 
This species was first described by Hewitson from a specimen in Dr. Boisduval’s 
collection, said to have been sent from Mexico !, from which country we have seen an 
example in the Berlin Museum. It is not uncommon in restricted localities in 
Guatemala, especially in the portion of the estate of San Gerénimo in Vera Paz called 
San Lorenzo, which skirts the hills surrounding the eastern end of the plain of Salama. 
It has also been sent us from the valley of the Polochic, but in smaller numbers. In 
1873, at the end of December, Salvin found Z. zea in the oak-forests of the eastern 
slope of the Volcan de Fuego, at an elevation of about 5500 feet above the sea. It 
was flitting in the open undergrowth of the forest, like other J¢homie, about four or 
five fect from the ground. WHewitson’s figure! has the dark marks of the primary 
wings coloured blackish brown; in our Guatemalan specimens these marks are rufous, 
in which also the subapical white spot of the primaries is usually, but not always, 
confluent with the next transverse diaphanous band. In the figure referred to this 
spot is quite isolated.

Leucothyris vicina, Butl. & Druce, P. Z. 8. 1874, p. 333°. 
L. zee similis, sed marginibus maculisque rufis angustioribus, vitta anticarum discali corpori propriore, et 
macula ad cellule finem magis triangulari; maculis duabus vitreis ad apicem in aream hyalinam omnino 
confluentibus: subtus anticarum puncto albo in limbo costali, nec in margine externo posito, punctis albis 
posticarum L. zee submarginalibus absentibus. 
Hab. Costa Rica (Carmiol!, Van Patten?), Irazu and Caché (fogers); PanaMa, 
Volcan de Chiriqui (Arcé, Zahn). 
A close ally of Z. zea, whose place it appears to take in the mountainous parts of 
Costa Rica and in the volcano of Chiriqui. It is rather smaller than Z. zea, and has 
all the dark markings of the primary wings smaller; the spot covering the end of the 
cell is triangular instead of subquadrate; and the mark across the cell is placed at a 
more acute angle and is nearer the body. 
5. Leucothyris esion. (Ithomia esion, Tab. II. fig. 4.) 
Ithomia esion, Godm. & Salv. Ann. & Mag. N. H. ser. 5, ii. p. 258. 
Alis fulvis, marginibus et dimidio anticarum apicali nigris, area apicali maculis quinque albis notatis, quatuor 
submarginalibus et una (maxima) extra cellulam ad costam fere attingente: subtus ut supra, sed alarum 
marginibus albo punctatis; antennis elongatis, nigris. 
Hab. Panama, Candelaria (Ribbe, Mus. Staudinger). 
A single male specimen (that described and figured) in Dr. Staudinger’s collection, is 
the only one we have yet seen of this species. JL. ewsion belongs to the L. illinissa
