CURRENT NOTES

It is announced that one of the parasites recently introduced from Europe as an 
enemy of the European Corn Borer, namely Exoristus roborator Fab., has been re¬ 
covered from the field by the collection of corn borer larvae from which the parasite 
has been reared. It seems extremely probable, therefore, that this species has 
succeeded in establishing itself in this country. The recovery of this parasite is 
recorded from five or six different localities. 
Mr. E. G. Smyth of the Bureau of Entomology, has left Guatemala for Mexico, 
where he w r ill investigate the bean beetle situation in the area between Mexico City 
and Vera Cruz, with especial attention to the localities in the vicinity of Jalapa and 
Cordova. This region is at the edge of the Mexican plateau, and it is hoped that 
any parasites collected in this vicinity will be more easily adapted to the climatic 
conditions in the southeastern portion of the United States. 
In response to a request from the National Park Service, Mr. J. C. Evenden left 
the Forest Insect Field Station at Coeur d’Alene, Idaho, June 6, to make an examina¬ 
tion of serious defoliation apparently caused by the spruce budworm in the vicinity 
of the Tower Falls and Camp Roosevelt section, Yellowstone National Park. On 
his return Mr. Evenden will make an examination of a Dendroctonus control project 
near Boise, Idaho, which is being conducted by means of logging, and also an area 
defoliated by the white pine butterfly. The Dendroctonus control project on the 
Helena National Forest was completed May 26. Approximately 500 trees were 
treated. 
Mr. J. R. Douglass, formerly connected with the Mexican bean beetle laboratory, 
Bureau of Entomology, at Birmingham, Ala., has established headquarters at 
Estancia, N. Mex., for the study of the Mexican bean beetle under western condi¬ 
tions. He reports that the dry conditions which existed during the summer of 1922 
and most of last winter are continuing to some extent, and the acreage of beans has 
been greatly reduced. Apparently the beetles are appearing from hibernation in 
much smaller numbers than usual—a condition which has also been reported farther 
south in New Mexico by Dr. Robert Middlebrook. It appears that the dry weather 
of last summer, together with the cutting-off of their food supply, has influenced this 
unusual condition. • 
On June 22 Miss Isabel Cooper, scientific assistant of the Williams Galapagos 
Expedition, brought to Washington for identification the Heterocera and Hymenop- 
tera secured by this expedition. It is understood that the types of all the new species 
are to be retained for the National Collection. These collections will be studied by 
Mr. Schaus and Mr. Rohwer. At the same time Miss Cooper took away several 
thousand Lepidoptera which had been secured by William Beebe while working at 
the British Guiana Experiment Station. These specimens had been identified by 
Mr. Schaus and are being returned to the New York Zoological Society for their 
collections. The work at the British Guiana Experiment Station and also the work 
done by the William Galapagos Expedition is carried on under the direction of 
William Beebe, with headquarters at the New York Zoological Gardens. 
On July 25th, about 25 representatives of the Federal Horticultural Board, Bureau 
of Entomology, and several near-by States, visited the Japanese Beetle Laboratory 
at Riverton, N. J., and apple and peach orchards in the vicinity. At a conference in 
the afternoon, C. H. Hadley and L. B. Smith explained the various phases of the
