OCHTHIPHILA Fallen. 



Hendel (Wien. ent. Ztg., XXIX, 313, 1910) and Coquillett (Type 

 Species N. Am. Gen. Dipt., 1910) prefer the name Chamccniyia Meigen, 

 1803, to the generally accepted Ochthiphila of Fallen, changing also 

 the subfamily name to Chamsemyinae. Chamccmyia was given by 

 Meigen in Illiger's Magazine as a genus, with no species mentioned. 

 In 1810 Panzer ^cscuhtA Chamccmyia clcgans.^ind therefore the genus 

 is usually accredited to him. In view of the present sentiment regard- 

 ing the overthrow of names in general usage, I regard it unnecessary 

 to discard Fallen's name Ochthiphila. 



Ochthiphila lispina Thomson, from California, is probably the 

 female of Schoenomysa litorella Fallen.
