COLLECTION OF INSECTS. 73 



insects or larvae that have been killed in alcohol, they should 

 be packed in cotton saturated with alcohol. In sending pinned 

 or mounted insects, always pin them securely in a box to be 

 inclosed in a larger box, the space between the two boxes to 

 be packed with some soft or elastic material, to prevent too 

 violent jarring. PACKAGES SHOULD BE MARKED WITH 

 THE NAME OF THE SENDER. 



In reply to numerous inquiries concerning entomo- 

 logical books, we recommend to the general student 

 'Harris on Insects Injurious to Vegetation,' and Packard's 

 'Guide to the Study of Insects;' and to those beginning 

 the study, 'Among the Moths and Butterflies, published 

 by G. P. Putnam's Sons, New York City. The last is the 

 only book of low price we know of that treats the subject 

 so as to make it interesting to the young.
