advanced for Aphis limitation. Conjecturally the chain might be 
lengthened still further by supposing the Myinide, which are 
frequently bred from Aphides, to be parasitic on one of the above- 
mentioned Chalcids. This treble-linked parasitism is clearly 
foreshadowed, for, on plate 64, Mr. Buckton figures a cocoon of 
Coryna (= Chrysolampus) containing five small pupe of its 
parasite (fig. 4). However, parasitism to the second degree is 
sufficiently involved for present study, and more especially here, 
where we introduce the collateral parasites of the various external 
natural protectors, which are also numerous. 
The relation of Aphides to ants, many species of which keep 
them captive like herds of cattle; the secretion of honey-dew ; 
the individual appearance and habits, whether lethargic or active, 
in which the species greatly vary, and other interesting points, 
have not been touched upon. Enough still has been said, I hope, 
to stimulate some further. enquiries into the manners and 
customs of these insects which have now found so excellent an 
historian.

UNuSsUAL FOOD FOR THE LARVA OF CHGROCAMPA PORCELLUS. 
—While searching for the larve of Cidaria silaceata on the 
Epilobium angustifolium (willow herb), I was surprised to take a 
fine full-grown larva of C. porecellus off a stem of the same plant, 
the leaves of which it had nearly devoured, as well as those of 
other stems.—F. O. Sranpisu; 8, St. Paul’s Terrace, Cheltenham, 
September 9, 1879. 
(At page 94 of Kaltenbach’s ‘Pflanzen-feinde’ we read: “This 
larva may be found from July to September on bedstraw (Galium 
verum), willow-herb (Zpilobium hirsutum and angustifolium), loose- 
strife (Lythrum Salicaria), and vine (Vitis vinifera).’—E. A. F.] 
DicRANURA BICUSPIS LARVa.—On Saturday last I had the 
pleasure of taking a single larva of this insect on alder. It was 
hardly earned, for, having a pole twelve feet in length to thrash 
the boughs with, the work was hard. My impression is that the 
larva feeds very high up the trees. The larva taken on Saturday 
is nearly full grown. I got a male specimen of the perfect insect
