This species has a known distribution throughout nearly the 

 whole of Europe, but Dalla Torre gives no eastern localities for 

 it ; it is very abundant in Britain, where two distinct forms occur 

 with equal frequency; the typical has the metathoracic spiracles 

 circular and the other (var. spiracularis, Mori., Ichn. Brit, iii, 

 p. 106) has them distinctly oval. It is to the latter form that the 

 Indian insect is referable ; and it also differs from the more com- 

 mon European one in having no rufescent coloration on the hind 

 tibiae, though I have seen similar specimens from Yorkshire. 



Dr. Chapman has given some interesting notes on the economy
