During the month the Museum hes sent to the Zoological Museum at 
Copenhagen a collection of 34 identified tenebrionid larvae. These larvae 
were selected from the material recently arranged by R. A. St. George. 
Prof. Herbert Osborn, of the University of Ohio, who was in Washington 
in connection with meetings of the National Academy of Science, spent April 
28 in the Division of Insects comparing some types of Hemiptera. 
T. B. Mitchell of Raleigh, N. C., attending the Federal Horticultural 
Board conference, spent a few hours in the Museum comparing various species 
of bees. 
April 21 Dr. E. A. Schwarz was eighty years old. To celebrate his 
birthday and to show appreciation for his kKindnesses the ladies of the Di- 
vision of Insects gave him a magnificent bunch of roses with appropriate ; 
greetings. The same evening a dinner attended by 26 people was given in his 
honor at the Cosmos Club, at which Dr. Howard acted as toastmaster. Speeches 
were made by Dr. B. Pickman Mann, Dr. C. W. Stiles, Dr. EB. D. Ball, Dr. d. 
M. Aldrich and others. Ali the speakers pointed out the value of Dr. Schwarz's 
services to the science of entomology, recalling instances that occurred dur- 
ing his past life. All expressed the opinion that the most important reason 
that Dr. Schwarz had so many friends was because he had always been willing 
to help others and had taken so much interest in the work of younger men. To 
these addresses Dr. Schwarz replied in his characteristic modest manner. The 
April number of the Proceedings of the Entomological Society of Washington 
was issued on April 21 with an appropriate editorial about Dr. Schwarz, and 
at the regular meeting dn May 1 Dr. Howard gave a brief talk and exhibited a 
dozen lantern slides showing pictures of Dr. Schwarz taken at various times 
Since his connection with the Department of Agriculture.
