NOTES ON THE STREPSIPTERA AND THEIR HYME- 
NOPTEROUS HOSTS . 1 
By George Salt. 
In the course of a study of the effects of stylopization on 
aculeate Hymenoptera, a number of new and interesting host 
records and various notes on parasitism by Strepsiptera have 
been accumulated. Although their varied nature render it some- 
what disjointed, it seems wise to bring these miscellaneous facts 
together in the present paper. 
The following is an annoted list of the eighty-one species of 
Hymenoptera of which I have examined stylopized specimens. 
Two genera, Zethus and Montezumia, and several species ap- 
parently constitute new host records.

Banks).
