84 ENTOMOLOGICAL NEWS. [Feb., 'l2 



date September 2oth. From that date until October "th, I saw the 

 moths nearly daily, but the height of the "Migration" seems to me to 

 have been about September 28-30. At night thousands of the moths 

 could be seen flying around the electric lights and quite a number flew 

 into my room to the lamp. 



It would be of interest to know whether the swarm in Milwaukee 

 constituted a separate migration or whether it had merely separated 

 from that which wended into Philadelphia. At any rate, this much 

 seems certain to me : the swarm followed the shore line of Lake Mich- 

 igan. I remember determining a specimen of the species for a gentle- 

 man in Kenosha a week ago; Kenosha also lies at the shore. Further, 

 one of the Museum staff brought me two specimens from Lake Okau- 

 chee, Waukesha Co., about 20 miles west from here, which would indi- 

 cate that the swarm was not confined to the immediate shore line. The 

 latter specimens bear the date October 3rd. 



I have written to my friend, Mr. Gerhard, at the Field Museum, 

 in Chicago, to see whether he, knows anything of the matter. I shall 

 also write to several correspondents in Wisconsin and see whether [ 

 can learn similar observations from them. The species is by no means 

 rare in Milwaukee. I have repeatedly taken it on sugar and at the 

 electric lights. R. A. MUTTKOWSKI, Public Museum, Milwaukee, Wis. 



Entomological Literature. 



COMPILED BY E. T. CRESSON, JR., AND J. A. G. REHN. 



Under the above head it is intended to note papers received at the 

 Academy of Natural Sciences, of Philadelphia, pertaining to the En- 

 tomology of the Americas (North and South), excluding Arachnida and 

 Myriapoda. Articles irrelevant to American entomology will not be noted; 

 but contributions to anatomy, physiology and embryology of insects, how- 

 ever, whether relating to American or exotic species, will be recorded. 

 The numbers in Heavy- Faced Type refer to the journals, as numbered 

 in the following list, in which the papers are published, and are all 

 dated the current year unless otherwise noted. This (*) following a 

 record, denotes that the paper in question contains description of a new 

 North American form.
