The dimorph of the second species is apparently the same as 
that found by Mr. Bragg in Colorado and myself in Minnesota. 
Kessler’s figure shows the 22 flabellz on the abdomen, while 
Buckton is evidently at fault as to the number in his figure. As 
our American material appears to agree in all respects with the 
figures and descriptions of the European, I have for some time 
held the two to be the same and that it should be known as 
Chaitophorus testudinatus (Thorn.) Kessl., 1886. Kessler’s 
third form has no dimorph, but continues to produce the spu- 
riz during the summer as usual in the family. 
The question if Chaitophorus negundinis Thos., 1878, should 
be considered as a synonym, or if we also have two or more 
species under one name, may best be left an open question until 
the life history of our maple Chaitophorus is better known 
than at present. 
The fact that the summer generations of the first two remain 
as larve unchanged for three months or more, Kessler con- 
siders as a summer sleep or hibernation; in which case it may 
be better to speak of it as a specialization and not as a degen- 
eration.

An Aphid Feeding on Coccinellid Eggs. 
By A. ARSENE GIRAULT. 
During early June, 1907, I had in confinement a number of 
pairs of the ladybird Megilla maculata DeGeer, in the labora- 
tory at New Richmond, Ohio. Each pair was confined in an 
ordinary glass tumbler covered with cheesecloth, and every 
morning a twig of plum, badly infested with an aphid espe- 
cially common on that food-plant in that vicinity, was intro- 
duced to serve as food. These aphids were eaten voraciously 
by the beetles. The female beetles were occasionally deposit- 
ing eggs in small batches of about from ten to fifteen, and 
quite often it was noticed that these eggs failed to hatch. At 
first this was thought to be due to infertility, although in sev- 
eral instances the egg masses were found to be thickly covered 
with aphids which had left their wilting or wilted food; besides 
the pairs of beetles were mating and some of the eggs deposited 
by them had hatched.
