NEUEOPTEROID INSECTS FROM SZECHWAN — ^BANKS 175 



Various genera now typically tropical are present in Szecliwan; 

 these, however, are commoner in eastern China. These genera are 

 Nothochrysa^ Ankylopteryx^ Neoperla^ /Spilos'mylus, Dipseudopsis, 

 Notanatolica^ Indophanes^ Polymorphanisus^ and Hydrotnanicus. rep- 

 resented by only one or two species each. 



In spite of the infusion of elements from other regions, the 

 Himalayan element is dominant in specimens and species. Although 

 there are here recorded 107 species, and a few others have been de- 

 scribed from Szechwan, this is probably less than half of the number 

 that will eventually be found in this rich province. Thirty-six species 

 are described as new.
