NOTES. ANSWERS TO CORRESPONDENTS. 447 
Tue Boston Society of Natural History have very wisely rapes 
to offer the Annual Walker Prize for 1873 for a memoir “On t 
development and transformations of the Common House Fly,” oe 
not only carrying out the liberal bequest of Dr. Walker, in offer- 
ing pecuniary assistance to worthy investigators, but at the same 
time calling attention to how little is known of the early life-his- 
tory of one of the most abundant of insect pests. Trusting that 
the prize may induce several of our entomologists to turn their 
attention, for this year at least, to the much neglected group of 
Diptera we refer to the advertisement for particulars.
