In a recent communication from Miss Ormerod, already mentioned 
on p. 196, she writes as follows of a predaceous insect discovered p her 
nt, Mr. Bairstow, of Port Elizabeth, Cape Colony 
“It will gius be of some interest to mention that Mr. Baik tow 
un species of Coccinella which has proved (as far ou 
Soleopierists are aware) to be ge iously undescribed, to be so exceed- 
ingly serviceable in destroying the ‘ ustrali an bug,’ as bec eall =

description and a figure, as Rodolia icerye.” 
Parasites.—It is a somewhat reisicialilo faet that no true parasites 
were ever bred from the Cottony Cushion-seale until the past summer, 
and still more remarkable that in the course of their careful investiga- 
tions, extending over a space of six months, neither Mr. Coquillett nor 
Mr. Koebele sueceeded in finding a singie parasite upon this insect. 
From a number = scales, however, sent to Washington by Mr. Koebele, 
November 10, bred, on December 8, two specimens " a small 
Chaleid, which is, without question, a true parasite of Icerya, as the

REMEDIES AND PREVENTIVE MEASURES. 
We have indicated in the introduction to this report the more im- 
portant results of the experiments carried on at Los Angeles by Messrs. 
Coquillett and Koebele, and as their reports are later given in full we 
shall refrain from entering into detail here, and state only a few of the 
more important convictions that curn us after the first week's 
experienee in the orange groves of Californ 
Importation OF PARASITES. Mr es general —€— of the intro- 
duction of parasites which affect a species in its native land, and which 
have not ac ccompanied it into me land of its introduction, has been 
insisted on in our earlier writings and in those of others, and the ease 
with which this may be y in the case of the more minute parasites of 
scale insects adds to its importance in their connection. Jonsidering 
the fearful one already iR to California orange growers by t 
species (the Jce ma in question and the California Red Sea

nor anticipated by committees.
