A New List of Coleoptera of North America. 



As indicated elsewhere in this number of the Xews, Mr. C. W. Leng, 

 of New York, the well-known Coleopterist, has prepared a new list of 

 the Coleoptera of North America, the publication of which will depend 

 on the extent to which advance subscriptions shall be secured. As 

 the list will be very useful, it is to be hoped that as many entomolo- 

 gists as possible will come to the aid of this praiseworthy undertaking. 



Early Appearance of Lycaena antiacis and xerxes (Lepid.) in 1917. 



Following my usual yearly custom, I collected early in 1917 on the

April 13th — Four xerxes 3^9, and five antiacis 3^29 taken, also 

 a Lycaena with white dot like a black center, just perceptible on close 

 examination, which I cannot identify more closely, although it is either 

 antiacis or xerxes; numerous Colias and Melitaca seen but not taken. 



April 20th — Weather good, sun obscured. Three xerxes $ , two 

 antiacis 9 $ taken. Many more could have been captured, but I

 deposited three eggs on a bud, each on a different section of the bud; 

 it then flew to another lupine and deposited seven eggs scattered over 

 four buds. The buds bearing the eggs were placed in a breeding cage,
