Vol. IX] EVERMANN— DIRECTOR'S REPORT FOR 1919 381 



at Mazatlan, Mexico ; and smaller series from Major Chapman Grant of 

 Oklahoma City, Mr. J. C. Huguenin of San Francisco, and from Dr. 

 Evermann, Miss Eastwood, Mr. Mailliard, and Mr. Little of the Academy 

 staff, and others. These figures do not include many donations of most 

 valuable material which it has been impossible for the curator to mount 

 and prepare for incorporation in the collections of the Academy. These 

 will be acknowledged later when help for mounting them is available. 



The field trips of the curator with the material obtained are as follows : 

 March, three days at Carmel with Mrs. Van Duzee, as guest of Mr. L. S. 

 Slevin, 956 specimens ; April, nine days by automobile from Bradley to 

 San Luis Obispo and return, with Mr. L. S. Slevin, 1,628 specimens ; 

 May, six days on the Channel Islands of Anacapa, Santa Cruz, San Miguel, 

 and Santa Rosa, with members of the Academy staff, as guests of the 

 California State Fish and Game Commission, 1,965 specimens ; June, three 

 days with Mrs. Van Duzee at Santa Cruz as guests of Mr. and Mrs. 

 E. A. Dodge, 1,002 specimens; July, one month with Mrs. Van Duzee and 

 Dr. and Mrs. Blaisdell at Huntington Lake, Fresno County, 4,810 speci- 

 mens ; August, three days at Stockton, 630 specimens ; and various short 

 trips about the bay region on Sundays and evenings, 1,513 specimens. 



During the year considerable progress was made in the classification and 

 arrangement of the collections. Most important is, perhaps, the work 

 accomplished on the Diptera or two-winged flies. Material in that order 

 has been determined by Mr. J. R. Malloch of Urbana, Illinois, Prof. J. S. 

 Hine of Columbus, Ohio, Mr. E. T. Cresson, Jr., of Philadelphia, Air. 

 C. P. Alexander of Urbana, Illinois, Mr. C. W. Johnson of Boston, Mr. 

 M. C. Van Duzee of Buffalo, and Mr. A. L. Lovett of Corvallis, Oregon, 

 but of most value has been the help received from Mr. F. R. Cole 

 of Stanford University, who has worked over our entire collection, de- 

 termining a large number of species that had not been studied by other 

 specialists and assorting and placing in the arranged series the numerous 

 species added during the year. Fifteen families in this order have now 

 been classified and arranged. In the Lepidoptera Mr. W. S. Wright of 

 San Diego has completed the determination of our material in family 

 Geometridse and the curator has arranged these and has also worked over 

 and arranged the material in the Noctuidae, .(Egeridae and Hepialidae, de- 

 termining many species and verifying others where their determination 

 seemed doubtful. In the Coleoptera, or beetles. Dr. F. E. Blaisdell has 

 again given much time and effort to the determination of our material and 

 the increase of our collection. Additional assistance has been received from 

 Dr. E. C. Van Dyke in the Elateridae and Buprestidae and from Mr. Ralph 

 Hopping in the Cerambycidse, and the latter family and the Tenebrionidae 

 have been re-arranged in new boxes after the forthcoming Leng Catalogue, 

 proof sheets for this purpose having very kindly been loaned to the 

 Academy by Mr. Leng. In the Orthoptera, or grasshoppers and their 

 relatives, almost the entire series has been sent to Mr. Morgan Hebard of 

 Philadelphia for study and another year should see that order in excellent 

 shape.
