it must be added that modern Gryllacris includes a great mul- 

 titude (over 170) of species, having various diverse characters, 

 and spread over the Neotropical, Australian, Oriental, and 

 Ethiopian regions. The venation of some of these (e. g. Q. 

 tibialis Serv., G. signifera Stoll, G. larvata Rehn) is strik- 

 ingly diverse, but is probably very variable within specific 

 limits.

Tipula (f ) hepialina sp. nov. 



Pupa slightly over 21 min long, nearly uniformly cylindrical, 

 breadth in middle 5 ram ; wing sheaths short, their tips about 

 7 mm from the cephalic end. 



1 had at first supposed this pupa to be lepidopterous, closely 

 related to Hepialus. On examining it with a microscope, the 

 compound eyes of the imago could be seen partially preserved, 

 with many distinct facets, and these occupied a space appar- 

 ently too large for the eye of any Hepialid, but accorded very 

 well with the Tipulids. It was then noticed that the leg- 

 sheaths extended far beyond the wing-sheaths, quite as in the
