24 THE ENTOMOLOGIST. 
brought to me alive. This is the Cerambyx heros of Stephens’ 
‘Manual.’ There appears to have been some confusion with this 
insect. According to Stein and Weise, in their ‘ Catalogus 
Coleopterorum Europe,’ the synonymy should stand thus:— 
Genus Cerambyx, L. ; cerdo, L. = heros, Scopoli; scopolii, Fuessly, 
=cerdo, Scop. The latter insect, Scopolii, is the cerdo in 
Stephens’ ‘ Manual,’ and has been taken on willows about Dept- 
ford and Isle of Ely. Stephens makes Fabricius the author for 
both heros and cerdo, but M. Marseul, in his ‘ Kuropean Cata- 
logue’ (1866), omits the name heros, and gives cerdo, L., and 
Scopolu, Laicht. Is the latter synonymous with Scopoli, Fuessly ? 
C. cerdo (heros) has occurred at Portsmouth Dockyard, and various 
Other places, at long intervals, and, although many entomologists 
are of opinion that it existed here in former days when our 
forest-land was more extensive, the fact of it generally occurring 
in places where there is shipping leads me still to believe that it 
is only imported amongst foreign timber.—C. G. Hau; 3, Gran- 
ville Road, Deal, Nov., 1882. 
STuDENTS oF DIPTERA WANTED.—Having for over twelve 
years collected Lepidoptera, I now intend to collect Diptera. 
The purpose of my calling attention to the fact 1s simply to 
obtain help through the kind correspondents of the ‘ Ento- 
mologist.' I shall be grateful for information relating to the 
distribution and habits of any species or genera of Diptera; for 
specimens forwarded to me I will endeavour to send their 
exchange value. I shall also be happy to have my attention 
called—by letter, or notes in the ‘Entomologist’—to any 
memoirs, monographs, or notes on the order. Hoping to meet 
with a favourable response.—HeErRBerT EK. Norris; St. Ives, 
Hunts, December, 1882. 
[Certainly the study of our Diptera is sadly neglected. With 
the help of Schiner’s ‘Die Fliegen,’ of the Fauna Austriaca, 
much progress may readily be made. Messrs. G. H. Verrall 
(Newmarket) and R. H. Meade (Bradford) are the British 
authorities on the order.—E. A. F.]
