FRAGRANT BUTTERFLIES—CLARK 44] 
much the larger and handsomer insects. In four males Mr. Long- 
staff found a faint, but distinct, scent of a sweetish character, some- 
times suggesting molasses, sometimes tobacco. In eight females he 
found a decided sweet and flowery scent. He once compared it to 
syringa, but in two other individuals it seemed to have rather a 
balsamic character. Mrs. Longstaff said that it was “sweetish, like 
some flower, not quite syringa—not so strong.” In no other butter- 
fly does the female have a sweet, flowery scent stronger than the male. 
Lycenids.—The hair-streaks, blues and coppers, which together 
make up the family Lycenide, are all quite small, the largest only 
slightly over 3 inches in expanse. Most of them spread from 1 to 1% 
inches, or in North America from 1 to 114 inches, while.a few do not 
exceed half an inch. Considering their small size and delicate build 
it is remarkable that many of them have a scent sufficiently strong 
to be detected. 
Our common little blue (Cyaniris ladon) as described by Mr. 
Scudder has an exceedingly delicate odor which he compared to that 
of newly stirred earth in the spring, or of crushed violet stems. He 
specifically stated that he could not discover any odor in the males of 
Rusticus scudderi. 
Six out of eight males of a close relative of our little blue occur- 
ring in Ceylon (Cyaniris singalensis) were found by Mr. Longstaff 
to have a scent of varying intensity, described in all cases as sweet, 
once as luscious, and once as /’reesia-like. 
In the common blue in England (Lycena icarus) both Doctor 
Dixey and Mr. Longstaff found in the males a decided scent sug- 
gestive of chocolate candy. In the English Chrysophanus astrarche 
Mr. Longstaff found in a male the odor of chocolate “not flavored 
with vanilla.” | 
In tropical America Mr. Longstaff found in a male of the very 
small Catachrysops hanno a very strong Freesia-like scent; but most 
of his specimens appeared to be quite odorless. 
Mr. Longstaff writes that 10 males of Polyniphe dumenelii gave 
positive results of a surprising character. In the majority of cases 
the odor was strong or even very strong; moreover, it was disa- 
greeable. He compared it to pig sties, or perhaps more correctly to 
pigs. It seemed to him scarcely credible at first that so small a but- 
terfly could smell so strongly. A female was odorless. 
In a male of Theclopsis tephreus examined in Venezuela a strong 
peculiar rather disagreeable odor was detected. A male of Z'molus 
cambes yielded an odor of molasses; Mrs. Longstaff compared it to 
coarse brown sugar. A male of Z’molus palegon had an odor of 
chocolate. In 7hecla atys in Brazil Fritz Miller found an unusually 
strong batlike odor in the male, and he also found more or less
