LEPIDOPTERA IN ROXBURGHSHIRE 165 



species emerge, viz. from / to I o A.M., and again from 5 to 

 8 or 9 P.M. ; and in my experience in successive years, the 

 same species emerged within the same hours. As is well 

 known, Lepidoptera can be abnormally forced to emerge 

 from the chrysalis state by artificial conditions of heat and 

 moisture ; and I have forced specimens of Smerinthns popitli 

 and tilia; and other summer species in the month of January, 

 but any rule of emergence under such artificial conditions 

 will probably not hold good. I may say that the forced 

 specimens were normal, excepting in colour, which is usually 

 paler. Following is the list :
