name is spelled boisduvallii in both the text and index of Harris 
(1862) indicates that the double “1” was the form used in the 
Harris manuscript, and this is confirmed by its use in Morris’s 
(1862) citation from that manuscript. Unfortunately, then, boisdu- 
valli is technically a “correct original spelling” and cannot be 
emended under the Code. 
Summary of Characters. — Lethe eurydice eurydice is relatively 
pale, pinkish brown above, somewhat yellowish beneath, with the 
postmedial line deeply indented beneath on all wings. The male 
valve is strongly 4-sided when viewed laterally, and the tegumen is 
dorsally rounded. The larva appears superficially to have dark side- 
stripes on the head capsule, extending from near the tip of the horns 
to the ocelli. These and other characters are discussed more com- 
pletely under the headings “Diagnostic Characters” and “Biological 
Differences,” after the taxonomic treatment of Lethe appalachia , 
below.
