LEUCOTHYRIS, 37 
LEUCOTHYRIS. 
Leucothyris, Boisduval, Lép. Guat. p. 82 (1870). 
Antenne moderately long; costa of secondaries of male gradually curved ; lower 
discocellular bent to an acute angle where it emits the recurrent nervule; upper 
segment long, and in a line with the long middle discocellular ; upper discocellular 
directed slightly forwards; distal segment of subcostal very short; proximal segment 
much longer than the three segments of the median nervure, and consequently the 
subcostal portion of the cell is very long; costal and subcostal nervures close together. 
Tarsus of front leg of female with five joints, with a pair of spurs on each of the second 
and third joints. (Type Jthoméa ilerdina, Hew.) 
These characters group a number of insects of considerable diversity of coloration, 
but of common wing-structure. The cell near the subcostal nervure is produced quite 
into the region of the apical angle in some species, as in L. rudescens and L. victorina, 
and especially in L. vicina. In L. makrena, though this part of the cell is not so long 
as in those just mentioned, it is still considerably longer than that part which lies next 
the median nervure. 
Leucothyris is represented in Central America by seven species, of which L. victorina 
enjoys a wide range, extending from Mexico over the whole area of Central America, 
and passing into South America as far as Bolivia. JZ. zea is peculiar to Mexico and 
Guatemala, its representative in Costa Rica and Panama being L. vicina. Costa Rica 
and Panama have also two more peculiar species in L. rubescens and L. pagasa; in 
Panama alone has L. esion at present been found; and here too the common Colombian 
species, L. makrena, has also been met with.
