gress of certain mosquito extermination work compels me to 

 say that I greatly fear there is going to be sad disappointments 

 and that the cause is going to be greatly retarded by a heavy 

 failure in promised results. All mosquito work demands the 

 most radical methods and anything less should not be recom- 

 mended by anyone who appreciated the necessities of the case, 

 unless he was blinded by an overruling confidence in his 

 abilities and knowledge. 



Personally, I would prefer to await results and then let others 

 do the puffing and not myself. I should prefer to be less dog- 

 matic, less opinionated and very careful not to draw positive 

 generalizations on insufficient data, especially in investigations 

 as new as those of mosquito habits and destruction. 



A few years will be sufficient to determine whether a radical 

 or a superficial course of treatment is the better. 



But to close what has been made lengthy by the number of 

 insinuations, taking but a word or two to express, possibly it 

 would have been safer if attention had been paid to the in- 

 jurious words of Dr. S. in the first instance, for usually a per- 

 son of the mind he seems to have is only encouraged by the 

 weakness of his victims. HENRY CLAY WEEKS, Bayside, L.

2. What the normal pupating habit of the species is. 



3. Whether such habit is known in any other Lepidopter- 

 ous insect. 



On July 8, 1897, in the Catskill Mountains I took two of 

 these larvae feeding upon the leaves of the Bush Honey-suckle 

 (Diervilla trijida). They were nearly full grown and when 

 captured were greatly disturbed, holding with the hind legs to 

 the twigs and elevating the body, at the same time shaking 

 in a tremulous fashion, as if seized with a chill, quite geome-
