406 THE CANADIAN ENTOMOLOGIST. 



Dr. E. J. Lund (Johns Hopkins University Circular, 191 1, NS, No. 2, 

 pp. 10-14), has observed that of the Lampyrids of Jamaica, only 

 Photiims pallens Browne showed any decided positive reaction to light 

 stimuli, and in this case the reaction was very slight, whereas the 

 Elaterid fire-fly of the same island, Pyrophorus plagiophthal)7ius Germar, 

 was strongly attracted to light. 



In the writer's experience, a single specimen of the male of 

 Lecontea lucifera has been observed to exhibit attraction toward light, but 

 the species of Photinus seem, for the most part, to be quite devoid of 

 this property. Both the males and females of Photuris pe?insylvanica 

 have, however, been known to come to light, and several instances of 

 this have come under the writer's observation. 



Since the foregoing paper was written, Mr. Frederick Knab, of the 

 U. S. National Museum, has called the writer's attention to a brief note 

 by Osten-Sacken (Die Amerikanischen Leuchtkiifer, Stett. Entomol. Zeitg., 

 1 861, Vol. 22, pp. 54-55), in which are recorded observations upon 

 Phothiiis pyralis^ made here in Washington, and which are practically iden- 

 tical with those given herein for the normal conduct of this insect. Hence 

 the writer's observations on pyralis can be considered only as confirmation 

 of the earlier observations of Oiten-Sacken ; in view of the fact, however, 

 that Osten-Sacken's paper appears to be very little known, and has been 

 overlooked by the majority of those who have contributed to this subject, 

 it seems justifiable to leave the paper in its present form, making this 

 acknowledgment of the previous work. 



The assistance and criticism of Mr. H. S. Barber, of the National 

 Museum, is also acknowledged with pleasure. 



SECOND INTERNATIONAL CONGRESS OF ENTOMOLOGY. 



The Second International Congress of Entomology will be held at 

 Oxford, England, from August 12th to 17th, 191 2. Further particulars 

 will be announced shortly. 



The Executive Committee proposes to find for members of the Con- 

 gress lodgings in the town, or rooms in one or more of the colleges at a 

 moderate charge ; rooms in the college will be available only for men. 



'J he Executive Committee invites an early provisional notice of 

 intention to join the Congress, in order to be able to make the arrange- 

 ments for the necessary accommodation. 



The })roceedings of the First Congress are in the press, and will be 

 published shortly. 



All communications should be addressed to the General Secretary of 

 the Executive Committee, Malcolm Burr, care of the Entomological Society 

 of London, 11 Chandos St., Cavendish Square, London, W., England.
