Last fall a Louisiana sugar planter was able to save a good deal of 
money by referring to the records of the Sugarcane Insect Laboratory, which 
proved that the damage he suffered from the sugardane moth borer in 1925 
Wo NO worse than usual, ‘Because of alleged excessive darage, the factory 
buying his cane insisted on paying less than the regular price, but when it 
Was. shown by the Bureau records that the cane of this particular planter 
pa oNes, not unusually damaged he was granted the price for good cane. 
I. HE. Holloway and W. 2. Haley, cooperating with L. L. Janes, of the 
Bureau of Agricultural Economics, estimate that the damage to sugarcane in 
1925 caused by the sugarcane moth borer was 30 per cent of a full crop. . Only 
once previously since 1912 has the loss vy the borer reached this figure, 
A certain plantation which followed one of the recommendations of the Sugar- 
cane Insect Laboratory suffered only about half that loss, 
TAXONOMIC INVESTIGATIONS 
S. A. Rohwer, Entomologist, in Charge 
Dr. Wm. A. Hoffman and Dr. Clay Huff, of the School of Tropical 
Medicine, Johns Hopkins University, Baltimore, Md., visited the Division 
of Insects, U. S. National Museum, to examine the collection of biting flies 
and to consult with Dr. Aldrich. . 
This year Dr. Boving has again received a very valuable addition to the 
Museum collection, Seventy-seven vials containing coleopterous larvae, most 
of the material having been reared, were sent him by E. Rosenberg of Copen- 
hagen, Denmark, | 
C. F. Ws. Muesebeck and R. Brown, of the Gipsy Moth Laboratory, Melrose 
Highlands, Mass., spent some time in the Museum in the last week of February. 
This visit was incidental to preparations for a visit to Europe on parasite 
work, 
In February a small but extremely valuable collection, comprising about 
150 specimens of holotypes and paratypes of 23 species of parasitic Hymenoptera 
belonging to the superfamily Chalcidoidea, were received by A.B. Gahan for the 
National Collection. They include representatives, in most cases holotypes, 
of all of the species thus far described by Harold Compere, of the California 
Citrus Experiment Station, Riverside, Calif., a rising young chalcidologist, 
who has contributed then, 
Yoratypes of three species of Chalcidoidea described by P. H. Timberjake, 
also of the California Citrus Experiment Station at Riverside, were likewise 
recently added to the collection. Mr. Timberlake, whose work in this group 
is well known, has consistently followed the practice: of depositing represen- 
tatives of his species in the National Collection,
