On the leaves of Fagus few-
ginea.
An Erineum which grows on
the upper side of the leaf where it fol- lows the veins, forming bands or elon-
gated patches of a brown color. When
young, apparently of a whitish color.
When abundant, causing the leaf to turn
brown so that the position of growths
can be recognized by examining the
under side. Sometimes forming a close
velvety covering on the upper surface.
Never, as far as examined, very dark in
color. Sometimes associated with the
next, of which it may be a variety.
Hairs capitate.

Seymour) ; Ft. Mackinac, Mich., (from

20. On the leaves of Fagus few-
ginea. An Erineuin forming very dark
/brown patches on the under side of the
"leaf, between the veins. Patches vary-
ing in shape and extent, frequently elon- gated, sometimes forming a continuous
iband between veins. Color of all the
specimens seen dark brown, but prob-
ably lighter when young. When occur-
ring on the same leaf as the preceding,
and so presumably of the same age,
always the darker in color. Hairs cap-
itate, with rather long stalks, not notice- ably different from hairs on the upper
surface of a leaf received from Prof.
Trelease, but with longer stalks than
those from the upper side of leaves from Temple, N. H.
The growth is extremely common in
western Kentucky, where most
of the
leaves of a tree may often be seen bear- ing it.

NOTES. - The Massachusetts legislature
has granted another $75,000 to stamp out the gypsy moth.
The attention of entomologists should be drawn to an interesting paper by Mr. L. 0. Howard on the biology of the Chalcididae which appears in the current Proceedings of the U, S. national museum. A mass of details concerning insect-parasitism is there brought together in a highly instructive manner
which merits at least the perusal of every person engaged in any field work ; problems requiring solution are suggested by the
wholesale, and clews are given to others which are well worth following. The bio- logical side of entomology is in no danger of suffocation at the national capital with such men as Riley, Howard, and Schwarz at the front.
In the last number of Psyche, fig. 3 on p. 237, showing the antenna of Goniops en-
larged, is accidentally printed upside down.
