AN UNDESCRIBED NET-WINGED MIDGE 

 FROM JAPAN 



(Diptcra, Blepharoceride) 

 By CHARLES P. ALEXANDER 



There has been but a single species of net-winged midge 

 described from the Japanese Empire. It was with great in- 

 terest, therefore, that the writer discovered a second species in 

 a collection of Tipuloidea sent to the writer for determination 

 by Dr. T. Shiraki, Chief Entomologist of Formosa. The writer 

 is indebted to Dr. Shiraki for the privilege of studying this fly.
