REPORT ON CERTAIN GROUPS OF NEUROPTEROID 

 INSECTS FROM SZECHWAN, CHINA 



By Nathan Banks 



For more than 15 years Dr. D. C. Graham has been sending neurop- 

 teroid insects from Szechwan Province, China, to the United States 

 National Museum. In 1928 the late Dr. A. B. Martynov, stopping 

 at Washington, borrowed some of the Trichoptera and in 1931 pub- 

 lished a paper on them.^ Later some of the Plecoptera were lent to 

 Dr. P. W. Claassen and Dr. C. F. Wu. They described some species 

 in 1934.2 The great bulk of the material, however, remained unstud- 

 ied. In 1937 most of that on hand was lent to me, and in 1938 the 

 remainder and some more that had recently arrived. I induced Dr. 

 F. M. Carpenter to work on the family Panorpidae, and his report 

 has recently been issued.^ The present paper deals with all specimens 

 in the collection not considered by these authors. The main part 

 of the collection (including holotypes) is in the National Museum; 

 duplicates, when present, have been retained for the Museum of 

 Comparative Zoology. 



Szechwan is extremely rich in many of the groups of neuropteroid 

 insects. Dr. Martynov noted that this fauna resembled that of Tibet 

 more than that of more eastern China. This was due partly to the 

 lack of material from China. In recent years Dr. G. Ulmer has pub- 

 lished on large collections of Trichoptera from eastern China ; Father
