P. W. Oman spent the week of May 21 to 26 at the Carnegie Museum, Pittsburgh, 
Pa., examining types and determined specimens of species of neotropical Bythos- 
copinae, Cicadellinae and Jassinae (Homoptera: Cicadellidae) described by Dr. 
Herbert Osborn in the Annals of the Carnegie Museum from 1923 to 1926, Over a 
thousand specimens from the collections of the National Museum and the Bureau of 
Entomology were taken to Pittsburgh for comparison with the determined material 
there. The primary purpose of the trip was the examination of types, a necessity 
to complete a paper dealing with the classification of South American agallian 
leafhoppers, but other work was completed. Detail drawings were made of types of 
genera not represented in collections at Washington, Every possible courtesy wad 
receivec from Dr. Hugo Kehl, Curator of Insects at the Carnegie Museum, 
INSECT PEST SURVEY AND INFORMATION 

During the month this office took over several of the activities assigned to 
t when the new Division of Insect Pest Survey and Information was created on May 1.) 
A great many requests have been received for small exhibits, particularly 
those illustrating the more recently introduced insect pests. Many of these re~ 
quests could easily be filled with very simple riker mounts showing the life- 
history stages of the insects and examples of their work. It is suggested that 
those in charge of investizetions on these important newly introduced insects 
collect a large supply of material to meet this demand, preferably keeping in 
alcohol all insects except Lepidoptera, By making such exhibits available much 
educational work could be done at practically no cost, as the collection of this 
material could be incidental to the regular work in the field, 
_ In response to requests from correspondents, 745 Bureen publications were 
sent out during the period from May 1 to June 14, 
During the month (May) 13 press releases and 6 radio releases, originating 
in or approved by the Bureau, have been handled by this Division, 
PHYSIOLOGY AND TOXICOLOGY OF INSECTS 
Closer cooperation is being established between the Insecticide Division of 
the Bureav. of Chemistry and Soils an2 the Takoma Park, Md., laboratory of the 
Dureau of Entomology. Howard A. Jones, of the Insecticide Division, has moved 
his laboratory to this laboratory, where he will remain until the new quarters 
of the Insecticide Division are ready in Washington. The work of this laboratory 
was inspected by several members of the Insecticide Division, namely, R. C. Roark, 
CO. Me. Smith, HL, Js -datter. 7.3. LaForge, W. 0. Robinson, J. E. Fahey, J. Le 
Lusk, and F, Acree, It is expected that their visit will promote closer personal 
contacts between the men who develop insecticides and those who test them against 
insects. Doctor Haller and Doctor LaForge are beginning a new project on syne 
thetic insecticides, starting with phenothiazine, which was found very promising 
at this laboratory. Triangular cooperation with the Bureau of Plant Industry and 
the Bureau of Chemistry and Soils is also to be undertaken soon, A survey will be 
nade of the insecticidal value of specinens of the devil's shoestring (Cracca 
Virginiana), which will de collected in different parts of thé country. 
BEE CULTURE 
Nosena disease was very prevalent in the Somerset, Md., apiary this spring. 
At times literally thousands of bees were crawling all over the apiary, deserting
