acuminata, and the forewing spots m 2 and m 4 of the 
new species are shorter. From quadripunctata the new 
species differs in having all wing spots better developed. 
Brephidium barbouri Clench a Synonym of Brephidium 
EXILIS ISOPHTHALMA ( HERRICH-SCHAFFER) (LEPIDOPTERA : 
Lycaenidae). 
Lycaena isophthalma Herrich-Schaffer, 1862, Corresp.- 
Blatt. zool.-min. Ver. Regensburg, 16:141, sex not stated. 
Type locality: Cuba. 
Brephidium barbouri Clench, “1942” [1943] Psyche, 
49:58, two males. Type locality: Great Inagua Island, 
Bahamas. New Synonymy. 
An examination of the holotype and paratype males of 
Brephidium barbouri reveals that they are identical with 
isophthalma for the following reasons. In the first place, 
microscopic examination of the anal angle of the forewing 
fringe reveals that the white patch supposedly differ- 
entiating isophthalma from the dark fringed barbouri can 
be present in all intergradient degrees. One specimen of 
isophthalma examined had a well defined white patch on 
one wing and practically none on the other. Secondly, 
barbouri is supposedly darker both above and below than 
isophthalma. This appears to be the case if one compares 
the types of barbouri with the Nassau specimens of isoph- 
thalma in the Museum of Comparative Zoology, and ap- 
parently this is what Clench did. However, the Nassau 
specimens were collected in 1897, while the types of bar- 
bouri were collected in 1934. Therefore it seems quite likely 
that the difference in color is merely due to fading. Lastly, 
my comparison of the genitalia of the types of barbouri 
with those of isophthalma failed to reveal any differences 
in structure. — Nicholas W. Gillham, Harvard Univer-
