1. TNTRODUCTIOX AND HLSTORICAL REMARKS. 



The material used in this investigation was obtained at Holmes Chapel. 

 Cheshire, at the end of October 1917; a small number of fully grown 

 larvae were found in the decaying remains of a wasp's nest, the latter 

 apparently having been destroyed some time previously. The remains 

 consisted of parts of the nest and of the wasps, with organic matter of 

 other kinds, fallen leaves, etc. 



The larvae obtained were kept in the laboratory, and pupated soon 

 afterwards, remaining in the pupal state about fourteen days, but the 

 exact period was not noticed. Bouched) gives this period as eight to 

 fourteen days. 



I have to thank Mr C. (J. Lamb, M.A. of Cambridge, for his kindness 

 in confirming my identification of the adult, and Dr A. D. Imms, who 

 suggested this investigation to me in the first instance, and who has 

 assisted me in many ways throughout its course. 



De Geer (177()) has given a short description of tiu' life history of 

 this species under the name of Tipula lairinanun. Bouche (1831) also 

 has given an account of i1 as Srathojisr noir Oeoffr.. which is ]irolia])ly
