and I2th, none; the food plant — wild hollyhock (Sidalcea malvaeflora) 

 plants — all dried up. July 8th, none; September i.Sth, none; October 

 28th, none; November i6th, none, hollyhock plants not out yet; No- 

 vember 2Sth, none ; December 9th, none, the weather very hot ; De- 

 cember 20th, none, and the food plant not out yet; January 2Qth (1912), 

 fourteen imagos observed, the weather very fine and warm ; Febru- 

 ary 14th, six imagos seen but not collected, weather fine ; May 17th, 

 eight imagos seen but not taken. After March 17th, 1912, I did not 

 visit the locality again. 



It therefore appears that Calligrapha sigmoidea is a winter and 

 spring species. I have found the eggs, and young larvae hatching in 

 the winter and spring months. I also do not believe that the imagos 

 observed were the hibernating individuals that were coaxed out by 

 the fine weather during the months mentioned above, as some of my 

 colleagues have intimated. — J. C. HuguEnin, San Francisco, California. 



Third International Congress of Entomology. 



The Congress will take place in Vienna from the 5th to the 12th of 

 September, 191 5, in the rooms of the University. 



Besides numerous lectures, discussions, demonstrations concerning 

 the different branches of theoretical and practical entomolog>% it is 

 intended to visit the scientific institutions and public collections of 

 Vienna and to make some excursions in the neighborhood of the town. 

 Annexed to the meeting of the congress, it is intended to travel across 

 the Alps to the Adriatic coast and to visit some of the Karst caves. 



An entomological exhibition will be open during the whole meeting, 

 showing in the first place : Private collections important from a bio- 

 logical, ethological, geographical, economical or any other point of 

 view; objects of historical interest. Pictures, books, tables, maps, etc.; 

 optic or mechanic instruments; means of instruction, school collec- 

 tions, models, etc. ; objects of agriculture, sericulture and other 

 branches of practical entomology. 



All entomologists having the intention of taking part in the con- 

 gress or in the exhibition are invited to subscribe as early as possible. 

 Tickets for a member for life: at least 240 kroner. Tickets of the 

 member of the Third Congress, 24 kroner. Supplementary tickets for 

 accompanying family members, 12 kroner. Certain benefits (theatres

 send objects for the exhibition, are requested to give the necessary 

 indications for a definite program as soon as possible.
