in late autumn. I was not able to find the larva or pupa and though I 
examined scores of blackberry canes, both old and young, was not able 
to find one burrowed. And though nearly every leaf had one or more 
eggs under it, I was able to discover no diminution of healthy canes the 
next summer. My idea was that the eggs fall with the leaves in Autumn, 
hatch in the spring, attack the new growing canes, and the larvae live 
very near or below the surface of the ground. 
Last year in the same field I took only two specimens. 
Prof, C. V. Ailey of Washington D. C., in the 6th report of In- 
sects of Missouri pp. 111—-113. which he has kindly sent me, gives from 
reports received from correspondents and personal observation, a history 
of what Mr. Hy. Edwards has determined to be this same insect. He 
gives a description of the larva as well as the imago under the name Z7o- 
chilium rubi. The observations of his correspondents do not agree with 
my own, Mr. Wm. Saunders of London Ont. writes that the egg is laid 
upon the cane, on a space between two girdlings made-by the jaws of the 
insects. This girdling is certainly an anomaly, if not as well an im- 
possibility among the Lepidoptera. Harris says ‘‘the eggs are laid singly 
on the stem near a leaf or small twig.” I saw the female oviposit cer- 
tainly over a hundred times, and never saw her lay her egg, or attempt to 
lay it, any where but on a leaf. Several correspondents also write Prof. 
Riley their canes were largely destroyed by the larva which was_ partially 
grown when winter set in. In the case of hundreds of eggs in the field, 
and laid by impregnated females in confinement, I never knew one to 
hatch before winter ; all outside fell to the ground with the leaves. I 
sought with the most patient care for canes showing signs of being 
burrowed but never found one; some cases where I found a virgin female 
I examined every cane within a yard of the place. Of course I must have 
missed my object however. The differences I do not pretend to reconcile. 
There is much variation in the size and color of the specimens as 
well as in the sexes. The males vary from, 7 to 13 lines, the females from 
12 to 17 lines in expanse. Some have very much more yellow on the 
thorax and abdomen than others, the females on the average having the 
most. Some of these latter have the last three segments entirely yellow. 
The type of flavipes is one of these, and strongly differs from the typical 
marginata. 1 also secured a variety where the yellow of margiata is 
replaced by almost clear white. The markings are also not so heavy, 
and are obsolete on the anterior segments of the abdomen and nearly so 
on the thorax. The wings lack the russet shading, and on the coxae and fe- 
mora white takes the place of the yellow of marginata. Mr. Hy. Edwards
