A Tropical Butterfly in New Hampshire. 
My pear Doctor SKINNER—Will you be kind enough to tell me 
the name of a butterfly which alighted on the knee of a young woman 
at Intervale, New Hampshire? “It was about 4% inches in expanse, 
of the bright, metallic blue seen in some of Denton’s exhibited butter- 
flies, with no markings on the blue, but a bright golden yellow edge 
around the four wings. The yellow edge had some small marks on 
it.” It had no tails. 
The person who saw this said that she never saw one like it de- 
fore and her sister corroborates all the statements of color, etc. It 
seems to me an escape from some one’s cage of chrysalids, or a 
tropical butterfly far astray. 
The person is a rather more accurate observer than most non-en- 
tomological women, and is really desirous of knowing what her “vis- 
ion of beauty” was. We both shall be grateful if you can tell us 
from this description—CAROLINE GRAY SOULE. 
May have been Caligo atreus or uraius from Central America, 
brought in chrysalis stage on a fruit steamer—H. 5. 
On Labeling Specimens. A Suggestion. 
On labeling specimens. A suggestions-When a specimen is cor- 
rectly named and placed in its proper position in the cabinet, or a new 
species described and duly named, that act is only a preliminary and 
comparatively unimportant proceeding; the name is the handle by 
which we will further study and communicate the results of such 
study of the species, in all the various relations of its natural history, 
economy, internal and external anatomy, distribution, etc. To do this 
further work we need a good knowledge of the environment of a spe- 
cies on which to base our studies; so we have the locality label. Very 
often this: label is vague, inaccurate or indefinite, taken from a local 
or railroad map, the collector having the idea that the specimen and 
its taxonomy is the chief end of his endeavors. Some standard should 
be used, understood by everyone, and the only standards which are 
permanent and accurate are the topographic maps, termed quadrangles, 
being prepared by the U. S. Geological Survey. These sheets, about 
17% x I5 inches, include an area of 20 or 25 square miles, I mile to an 
inch, and more than one-quarter of this country has been thus mapped. 
The relief is shown by*contour lines, so one can obtain at a glance the 
topography of the region. The name of the sheet is designated by 
the name of the principal town or some prominent natural feature, as: 
Watkins Glen Quadrangle, N. Y., or Tejon Quadrangle, Calif. So 
with a printed locality label for the particular quadrangle, with the 
date, collector, and exact locality indicated by a town, canon, peak, 
river, boundary lines, etc. on the specimen, a student can turn to the 
particular atlas sheet (which sheets are very convenient and beautiful
