MORGAN HEBARD 23 



Our numerous requests for the loan of other entire collections, 

 or important historic examples, have in every instance met with 

 full compliance. Had it not been for this willing and generous 

 cooperation, it would have been impossible to undertake this task. 

 We would here express our deep gratitude to Mr. James A. G. 

 Rehn of the Academy, Mr. A. N. Caudell of the National Museum, 

 Dr. Samuel Henshaw of the Museum of Comparative Zoology- 

 Mr. Charles Schaeffer of the Museum of the Brooklyn Institute 

 of Arts and Sciences, Dr. F. E. Lutz of the American Museum of 

 Natural History, Dr. E. M. Walker of the University of Toronto, 

 Dr. J. Chester Bradley of Cornell University, Mr. F. Sherman Jr. 

 of the North Carolina Department of Agriculture, Prof. C. P. 

 Gillette of the Colorado State Experiment Station and curators 

 of other institutions, and to Dr. A. P. Morse, Mr. William T. Davis, 

 Dr. Henry Fox, Mr. M. P. Somes, Prof. W. S. Blatchley and Mr. 

 Charles S, Brimley, for the opportunity of examining material in 

 their charge or belonging to their collections. 



Subfamily PSEUDOMOPINAE 



The transition from the Ectobiinae to the present subfamily is 

 almost indefinable." The typical species of the former have the 

 femoral spines very delicate, and the male supra-anal plate very 

 weakly produced. In the Pseudomopinae the femoral spines are 

 heavier, the male supra-anal plate more strongly produced in 

 typical species. The first division of the Ectobiinae {Ectobius 

 and allied genera) have also a distinctive facies,-^ the tegminal 

 venation and form being chiefly responsible for this. 



In the first species here considered, we may note that several 

 features show close affinity with the first division of the Ectobiinae; 

 careful consideration of all the features, including the general

 tidae, Ectobinae, p. 6, (1907). That author later admits that attempts to define the 

 Ectobiinae and Phyllodromiinae (= Pseudomopinae) have all been unsuccessful, Gen. 

 Ins., Fasc. 73, Blattidae, Phyllodromiinae, p. 2, (1908). 



-3 The forms of the second division of the Ectobiinae {Anaplecta and allied genera), 

 have a general facies resembling in many ways Plecloptera and its allies, which are gen- 

 erally referred to the Oxyhaloinae, and are separated from those forms only by the 

 different character of tegminal venation, wing plication and absence of delicate femoral 

 spines.
