camera lucida. The whole process of mounting may be accomplished in 

 a minute or little more, or it may be mounted and sketched in five minutes 

 or less. In this way I have mounted and sketched hundreds of wings 

 of Tineidae, which I hope some day to publish in the pages of the

entomological notes. 

 Dear Sir, — 



Ceratomia qtiadricornis*. — I have during the past season, and for the 

 first time in my life, taken a number of the larvae of Ceratomia quadricornis 

 Harr., of a brown color. Out of five taken in one locality, four were of a 

 deep brown. The fifth was of the usual green hue. These larvae were 

 about half grown when captured. This was early in September, but since 

 then I have taken several other specimens, the majority of which were 

 brown. I should like to learn whether any of your readers have, at any 

 time, made similar captures. 



Doryphora 10-lineata. — A safe and effective method of destroying this 

 beetle is to drag an ordinary butterfly net over the haulm when the larvae 

 and beetles are feeding. By this method, and Avithout making any par- 

 ticular effort, 1 captured on Long Island, this year, over five hundred 

 specimens in about as many minutes. By making a sort of drag net, large 

 enough to be worked by two boys, a much larger number could of course 

 be captured in a given time. I have no doubt that Long Island will be 

 plentifully supplied with io-/iucata next year ; for, although thousands 

 were drowned and washed up on the beach at Coney Island and else- 

 where, the number that escaped must have been great. But, although 

 admitting the desirability of ridding ourselves of this pest, I by no means 

 admit that it is the scourge talked about by some Entomologists. As I 

 intimated before, we had plenty of them on this Island, but no one com- 

 plains of a small crop of potatoes in consequence.
