CLOTHILDA. 173 
The palpi have the terminal joint rather short, the middle joint being long, curved, but 
slightly swollen, and all the joints densely clothed with long hairs. The front legs of 
_ the male are covered with long fine hair; the coxa is rather attenuated; coxa = 
3 femur; tibia = femur + trochanter; tarsus long (single-jointed), >+ tibia. 
The male secondary sexual organ is very different from that of Argynnis. The 
tegumen, though projecting, is very feeble; the harpagones are large, but slenderly 
built, and without hooks; inside of them, however, is a strong hook on each side. 
The penis is long and sharply pointed. 
Six species are now known of this genus—two continental, both of which are 
mentioned below, and four peculiar to the Greater Antilles. Two of these latter are 
found in Cuba, and two in Haiti. Clothilda is one of the few genera found in the 
Antilles and in Central America and Mexico to the exclusion of the rest of America, 
both North and South. All the species are said to affect the forests of the higher 
mountain-ranges where a damp temperate climate prevails.

This beautiful species was first discovered in Southern Mexico by Deppe, whose 
specimens passed into the Berlin Museum, and were described by Klug in 18361. 
Probably about the same time the same species was figured in the third (uncompleted) 
volume of Hiibner’s ‘Sammlung exotischer Schmetterlinge’ under the name Anelia 
thirza, a title adopted by Mr. Kirby in his Catalogue ®, but without real evidence that 
it was published prior to that of Klug. Since its discovery C. ewryale has been found 
from time to time in Southern Mexico, and was captured by us in various parts of 
Guatemala in 1861-62. Here it is an inhabitant of the highland forests; and though 
observed as low as about 4000 feet in Vera Paz, it was nowhere so abundant as in the 
mountains above Quiche, at an altitude of over 8000 feet above the sea. Several 
specimens were captured there in the month of August as they flew lazily about the 
foot of a precipice reeking with the moisture of the rainy season. 
Mr. Champion has recently sent us specimens, all taken, like our own, in the highland 
forests of Guatemala.
