as this stage being in reality the penultimate stage. The form de- 

 scribed by Cockerell as the first stage larva of this species is prob- 

 ably either incorrectly described or does not belong with this 

 species, for he speaks of the presence of "figure-of-eight" pores 

 and of projecting anal lobes. The form described by him as the 

 second stage is what I here consider to be the first stage.

The Geometridae were, in cases of doubt, submitted to Mr, 

 A. F. Winn or to Drs. Barnes and McDunnough. 



In all the following species it was considered advisable to 

 give the changes as indicated by the new check list. But as it is 

 improbable that the collection will be re-arranged for a consider- 

 able period; the order of the species in the collection, that is, of 

 the Smith list, is adhered to. The names in brackets are those 

 given in Drs. Barnes and McDunnough's list. 



Geometridae.
