Type: Male, Colombia, Medellin (Antioquia), July 1959. F. Luis 
Gallego M. USNM 65823. 
Food plant: Ficus carica L. 
Described from the type male, 6 male and 11 female paratypes 
all with the same data. Paratypes in the U.S. National Museum and 
the collection of the Universidad Nacional. 
Of this striking clearwing moth Dr. Gallego writes: “El insecto 
a que me refiero hace sus dafios en ramas y tallos como borer, en 
donde sus larvas dejan grandes horadaciones; abunda en el Valle de 
Medellin y sus alrededores, lo mismo que en varios municipios del 
Norte, Noroeste y Suroeste de Antioquia; también en Bucaramanga 
y otros municipios de Santander del Sur, todos estos Jugares com- 
prendidos entre los 1.400 y 2.200 metros de altura. Abunda en todos 
los meses del ano. Julio de 1949 y siguientes.” 
In flight at the same time as lewcoteles, and easily confused with 
it, is a species of Amatidae, Macroneme sp., near evelina Druce. 
The resemblance in this apparent case of mimicry is remarkable. 
In the amatid the apical half of the forewing is a little broader and 
the white apex is a little more extensive than in lewcoteles.
