L. aurora Dogn. Male-. Head, thorax, and forelegs flame scarlet. Thorax pale flesh colour; abdomen 
dorsally suffused with rufous. Wings flesh colour, the terminal areas rufous; a few scattered black scales. Tore- 
wing: a fine black streak on discocellular; outer line merely indicated by different colour of terminal area; a 
lilacine white incurved shade from apex between veins 2 and 3. Hindwing: a faint medial line, straight to 
below middle of inner margin; the outer area somewhat paler, adjoining line from vein 4 to inner margin. Fore- 
wing below light coral red, except the incurved shade from apex. Expanse: 31 mm. Muzo, Colombia. 
L. valera sp. n. (88 e). Male : Head, throat, forelegs, and front of collar purplish red. Thorax and 
abdomen maize yellow, suffused especially on abdomen with purplish red. Fore wing maize yellow to outer 
line; terminal space purplish red; some reddish scaling at base; a fine dark line on discocellular narrowly edged 
with reddish; outer line inbent, wavy, slightly darker than termen; cilia black tipped with white. Hindwing 
maize yellow to outer line except the reddish streak along inner margin; a straight dark medial line to inner 
margin above anal angle; outer area and cilia as on forewing; some white and black scaling on inner margin 
below the line. Underside as above. Expanse: 33 mm. Valera, Venezuela. Forewing sinuous and crenulate 
at tornus, the hindwing slightly crenulate. Type in the U.S. National-Museum. 
L. asea sp. n. Male : Palpi, throat and frons ferruginous. Thorax and abdomen avellaneous. Wings 
from base to line ochraceous tawny, terminal space cinnamon brown, the cilia tipped with light buff. Forewing:

sinuous and crenulate from vein 3 to tornus. Hindwing crenulate. 
L. oyapoca sp. n. (88 e). Male-. Forewing with apex produced, not acute, termen faintly crenulate from 
vein 3 to tornus. Hindwing with termen rounded appearing crenulate owing to markings on cilia. Body tawny 
olive. Wings to line vinaceous buff suffused with light tawny olive. Forewing: a dark point on discocellular; 
costal edge rufous; outer line remote, dark, threadlike, slightly outbent on costa and their vertical; termen 
broadly tawny olive from above vein 8 to inner margin; cilia brownish olive tipped with white on interspaces 
and with light coral red at veins. Hindwing with line remote, faint, threadlike, from vein 2 upbent to inner
