April, '14] PADDOCK: OBSERVATION ON BEE-MOTH 187 



Some of the larvae which mature early in September may pass through 

 a short pupal period and soon emerge as adults. This accounts for 

 the appearance of a number of moths about the first of October. This 

 generation is usually small and scattered and many of the larvse which 

 result from the eggs of these moths seldom reach maturity. Some of 

 the larvse of the second generation do not pupate during the fall, but 

 live over the winter in the larval stage and pupate the following spring. 



The following summary shows the stages of the bee-moth which 

 normally occur each month of the year at College Station: 



April: Moths reach maturity from the over-wintering larvse and pupae. 



Eggs are deposited.

Some pupse.

Natural Enemies. Three hymenopterous parasites of the bee- 

 moth have been recorded. One is a chalcid, Eupelmus cereanus, found 

 by Rondani in Italy; another is a braconid, Bracon hrevicornis Wesm., 

 which was found by Marchal in France; the third species is Apanteles 

 lateralis Hahd., recently found by A. Conte in France.^ This last
