ceded by a paler band, separated from the median 
band by a darkish line also crenated posteriorly, 
The remainder of the wing is deep olivaceous 
with a paler band from the middle to the inner 
angle. 
Posterior wings purplish-red in middle, ex- 
tending near to, and darker toward the base, 
with a transverse black spot above the inner 
angle bordered anteriorly with very pale olivace-

in the male the wing is olivaceous exteriorly and 
has a long terminal border. 
Underside olivaceous, anterior wings with a 
triangular purplish-red spot with the apex at base 
and gradually fading to a very pale olivaceous 
band which crosses the middle of the nervules 
and extends across the posterior wings. The 
discal spot shown on the upper side is prominent 
on the under side.

Palpi reddish-brown or dark brown; head and 
thorax pale fawn-color, or pale grayish, with a 
more or less distinct thoracic, dorsal, brownish 
stripe. Abdomen fawn color. Anterior wings, 
from base to about the middle of the disc, pale- 
gray with a faint lilac tinge or pale fawn-color ; 
a brownish line crosses the basal part of the disc ; 
a broad median shade with its posterior margin 
commencing on the costa, midway between the

darkest at the edges, and ochraceous-brown, dark

almost obsolete above the medio-posterior vein, 
whence spring two lines which mark the outline 
of the shade; a line of the same hue parallel to 
the median shade with an intervening pale space, 
and a light colored shade near the hind margin, 
extending from the central discal vein to the

CORRESPONDENCE. 
Eps. Ent. Derr. O. and O.—Sirs: I have read the ar- 
ticle by B. on “scarcity of insects in 188485” with a great 
deal of pleasure, and I fully agree with him as to the 
“causes,” so far as he goes, but, when he makes the asser- 
tion that it ‘‘undoubtedly follows,” that a wet, stormy 
winter will be succeeded by scarcity of insects, I must dis- 
agree with him. It has been my experience that where in- 
sects were numerous their pup were plentiful during the 
winter previous. Such was not the case during the winter 
of 1883-4 and 1884-5, as it should have been, if the scarcity 
was caused by the pupe being winter killed. I considera 
drought, of sufficient duration to wither the foliage, one of 
the most potent causes of insect scarcity, as the food sup- 
ply of the leaf-eaters is not alone cut off before maturity of 
the larvie, but the plant itself becomes diseased, owing to 
its inability to breathe. One of my most infallible signs of 
acoming scarcity of insects, is to see the trees in winter 
clothed in their faded summer garments.— Cyanide. 
EGG COLLECTING, 
Editor of O. and O. Sir. No matter how much we may 
try to evade the question, it is a fact, that eggs taken from 
a nest will never multiply our feathered tribes ; on the con- 
trary, it has a tendency to a decrease, at least in certain 
methods of collecting, as practiced by a class of collectors. 
Living in a glass house myself, I will not throw any stones; 
but perhaps may be pardoned by my fellow collectors if I 
urge that method and carefulness be employed in their 
work. In my own case I divide the season into short 
spaces of about a week each, and jot down what birds I 
may expect to find nesting (for the first laying) during such 
periods of time. I then look forsuch birds as I am sure of 
obtaining from first sets and fresh in incubation. The 
birds immediately commence to build and layagain. Af- 
terwards I do not trouble them, and they rear their brood 
the same as thongh they had not been despoiled. I have 
found it to be the same with the species which naturally 
rear two broods, and at the close of the season find myself 
with a fair result, and an easier conscience, and, better 
still, a satisfaction that I have not diminished the bird-life 
to any extent. As a matter of course I find many fresh 
sets later than the allotted time for the particular species ; 
these I do not take, as they are usually second attempts at 
breeding, and if disturbed would entirely break up their 
nesting, and thus really diminish bird-life.” Something of 
my idea may be gathered from the aboye, and if every 
Odlogist would carefully study the breeding season, meth- 
odically conduct his collecting and refrain from the too- 
prevailing ‘“grab-all” system, I am of the opinion that cél- 
ogical collecting might be pursued without decreasing our 
birds to any alarming extent.—C. 7°. Weld.
