THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
species ? Do local species propagate up 
and down the course of streams ? Do 
species gradually migrate from one 
position to another ? 
All these are interesting problems 
which, hitherto, the scarcity of observers 
has prevented us from attempting, but 
the time will come, sooner or later, when 
such questions will be forced upon our 
attention, and who knows what startling 
events may serve to concentrate our ob- 
servations during “ The New Season ? ”

TO CORRESPONDENTS. 
R. T. asks where are the females of 
Versicolora to be found? We cannot 
speak from experience, but suspect they 
would be found amongst the low bushes 
where the species occurs. We have 
known the larva of the insect to be taken 
at Dulwich Wood, but that was before 
the Crystal Palace came to its present 
locality. Birch Wood and Darenlh 
Wood are probably now the nearest me- 
tropolitan localities. 
R. W., Woburn. — Your insect is 
Trichiosoma lucorum, one of the Saw- 
flies. 
H. R. M., Brighton. — Dipterous 
larva; have no feet , and generally no ap- 
parent head. “ Where can one learn 
about collecting, killing, setting and 
arranging, Diptera P ” We really cannot 
answer this question satisfactorily : per- 
haps some of our readers can help us. 
A. S., Rugby. — Your insect is the 
March Dagger ( Diurnea Fagella). 
Sallows. — We have had many 
enquirers, — 1st. What are sallows? 
2nd. How do you get the moths at them ? 
1. Sallows are broad-leaved willows 
which grow in bushes, and at this time 
of the year blossom : the blossom is like 
a small green gooseberry, into which you 
should have stuck a hundred long, thin, 
green, yellow-headed, pins. 2. The 
moths sit on the sallow-blossoms sucking 
the honey, from 7.30 to 9.30 p. m. : take 
a net and lantern, and beat the sallow- 
branches over your net, and you will get 
plenty of moths on favourable nights.
