312 Report of the Consulting Entomologist for 1885. 
To Turnips. — Aphides ; serious and widespread attack of 
turnip moth caterpillar, accompanied by one or two allied kinds. 
Likewise the grubs of the Bibio Marci (manure feeders, much 
resembling small Daddy Long-legs grubs), which were found 
at the roots of cabbages, and " Snowy Fly " — Aleyrodes — (an 
insect which in its early stage much resembles " Scale Insect") 
on cabbage leaves. 
Hop Aphis, Mustard' Beetle, Cockchafer, and other regular 
pests have, of course, been matters of correspondence. 
With regard to fruit attacks, enquiries have been made re- 
garding — Red maggot in pears ; the web-spinning caterpillars 
of the small ermine moth on apple trees; and the hairy, red- 
tubercled, and whitish-tufted caterpillars of the vapourer moth, 
which are very destructive to leafage of various fruit trees ; thfi 
Phgtoptus, a minute gall midge, sometimes seriously injurious 
in fruit farming by causing the growth of swollen abortive 
buds on the black currants ; also the gooseberry or magpie 
moth, and the gooseberry sawfly. Amongst forest or timbej 
insects, communications have been made regarding attacks of the 
great goat moth caterpillar, which is injurious to most of our 
deciduous timber and fruit trees ; the elm-bark beetle ; the leaf- 
roller moth-caterpillar of the oak ; and also the large purple- 
and-green fork-tailed caterpillar of the puss moth, which ap- 
peared on poplars in two localities in Forfar. Attacks of the 
Sirex Juveiicus, sometimes known as the " wood wasp," of which 
the grubs live in fir timber, and of Larch Aphis (a serious pest 
in larch plantations), were also reported. 
Many serviceable communications have been sent regarding 
Ox Warble Fly, of which I have already submitted a portion 
regarding the development of the Warble and Maggot. ,The 
observations, which give much useful information, especially as 
to methods of killing the maggot by applications which cannot 
do harm in the most careless hands, will be given at length in 
my own next Yearly Report on Injurious Insects. I am also at 
present collecting evidence as to the presence of Warble maggot 
in the human subject, which may throw some light on the 
nature and amount of pain suffered by cattle attacked. 
With regard to some of the more special points of the attacks 
of the year, one of these was the great amount of presence of 
corn aphides or plant lice. It is somewhat remarkable that, 
though a trustworthy description of attacks of what was ob- 
viously the true corn aphis (the Siphonophora granarid) was sent 
me from Kingsnortli, Kent, hardly any specimens of this species 
appeared to be pra*ent on any of the large number of infested 
ears sent to me lor examination, mainly from the more northerly 
parts of England. These aphides, in all their successive stages.
