Our Coccinellidae do not appear to have many Hymenopterous para¬ 
sites. I have, however, the dried skin of a nearly fullgrown larva of 
Coccinella g-?iotata Hbst., probably, punctured by several round holes, 
showing that a parasite had developed within and several individuals 
made their escape. Just what the parasite is, aside from its being a 
Hymenopter, I cannot conjecture, but the h( les for escape are un¬ 
mistakable. This was found at Painesville, Ohio, August 5th. 
Valgus canaliculatus Fab., Plate X, Fig. 3. This has come to be 
a fruit tree pest in southern Ohio, where the adult works very serious 
injuries by eating out the fruit buds of the pear and other fruits, in 
spring. I can find little regarding this habit in our literature, the 
single instance of this injury being recorded in Insect Life, Vol. 1, p. 
53, where Mr. W. W. Meech, Vineland, N. J., stated that the adult ate 
out the young buds of the quince. The larvae are known to develop in 
decaying wood, and my assistant, Mr. Mally, has found the beetles 
hibernating under decaying stumps. 
Ciioceris asparagi Linn., is making its way slowly but steadily 
west and southwest into Ohio, seemingly spreading more rapidly in 
these directions than to the southward. There is hardly a doubt but 
that it has made its way through New York, and along the south shore 
of Lake Erie, between the lake and the Alleghany Mountains, broaden¬ 
ing out in its area in northwestern Pennsylvania and northeastern Ohio. 
It now covers the area laying east of a line drawn from a point located 
some distance west of Cleveland, to near the point where Ohio, Penn¬ 
sylvania and West Virginia corner upon each other, and the Ohio river 
ceases to form the boundary line between the two States and passes into 
Pennsylvania at this place. Professor A. D. Selby, Botanist of the Ohio 
Experiment Station, informs me that an introduced plant, the Golden 
Hawk-weed, Hieracium aurantiacum L., a native of the Alpine regions 
of Europe, and introduced into this country prior to 1818, without 
much doubt, is now apparently spreading over Ohio from western Penn¬ 
sylvania in almost exactly the same way. 
In regard to Oberea bimaculata Oliv., I have only to again call at¬ 
tention to a point already published, unillustrated,* in regard to the 
astonishing amount of excreta evacuated by the larvae during the space 
of 24 hours. The adult is shown, slightly magnified, in Plate X, Fig. 
1, the larva, also magnified at the left. These larva: burrow out the 
center of the twig’as shown in Plate X, Fig. 2, cutting out round holes
