A New List of Coleoptera of North America. 



As indicated elsewhere in this number of the NEWS, 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 

 western slope of Twin Peaks, San Francisco, California (altitude 

 ranging from 200 to 800 feet). My observations were as follows: 



February 5th My first day out; white frost in A. M. No Lycaena 

 to be seen, two C alias and one Anosia plexippus taken.

 Lycaena to be seen, two C alias and one Anosia plc.vippus taken. 



March 6th White frost in A. M., weather fine. One antiacis, one 

 xerxes and two Anosia plcxippus taken. 



March nth White frost in A. M., weather bright but cold. Two 

 Colias and two Euchloe taken ; no Lycaena to be seen. 



March i5th White frost in A. M. No Lycaena to be seen, two 

 Euchloe and one Colin* taken.

 ausonidcs and two Lycaena acmon taken. Four Lycaena .rerxcs or 

 antiacis seen, but could not be captured on account of the high wind.

 taken ; numerous Colias, Pieris, plexippus seen but not taken. 



April I3th Four xerxes 3 $ 9 , and five antiacis 3 <J 2 9 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 Alclitaca seen but not taken. 



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

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

 preferred to observe their movements. Singling out an antiacis, 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,
