Kinsey: Studies of Cynipidse

able to build the structure of c^mipid biology. The students 

 of cynipid taxonomy must be the ultimate critics of the bio- 

 logic hypotheses we build, and for that reason I have included 

 a considerable body of biologic data with the taxonomic record 

 of each insect. These data are brought together in the index. 

 After the taxonomists have criticized, I shall draw these data 

 together into a more general form. 



The material on which these studies are based was mostly 

 collected during 1919 and 1920 while I held a Sheldon Travel- 

 ling FelloAvship of Harvard University. Fully half of the 

 new Cjmipidse I obtained at that time are not yet described, 

 and the volume of biologic data is not yet touched. This is 

 the second paper I have based largely on this material, the 

 first having been published recently (1922, Bull. Amer. Mus. 

 Nat. Hist., XLVI, pp= 279-295), and others should follow 

 soon. Great credit is due the Harvard University authorities, 

 especially Dr. William Morton Wheeler, who made the trip 

 possible. 



Eleven of the neAV varieties are described from material 

 which was collected and bred by Dr. J. T. Patterson, of the 

 Zoology Department of the University of Texas. Dr. Pat- 

 terson is undertaking probably the most extensive work 

 which has yet been done on cynipid life histories and genetics. 

 I greatly appreciate the opportunity to describe his material, 

 most of which I have not yet been able to study. ^Ir. C. W. 

 Johnson, of the Boston Society of Natural History, Mr. Will- 

 iam Beutenmuller, and Dr. A. L. Melander collected types, 

 each of one of the neAV varieties. 



A great number of friends have contributed largely to 

 my work. Mrs. Kinsey has generously contributed encour- 

 agement, time, and skillful criticism. I have secured gifts 

 or loans of material, particularly types, and other favors from 

 the Museum of Comparative Zoology, the American Museum 

 of Natural History, Mr. S. A. Rohwer and :\Ir. L. H. Weld 

 at the U.S. National Museum, Dr. Isabel McCracken at Stan- 

 ford University, Pomona College, Professor A. Trotter of 

 Portici, Italy, and a host of friends who are not biologists. 

 Mr. Frank A. Leach, of Diablo, Calif., is sending me mate- 

 rial. Dr. F. E. Lutz and Mr. Andrew J. ^Mutchler, of the 

 American Museum, haA'e especially aided the work. The 

 authorities of Indiana University, particularly the merabers
