History, the Canadian National Collection, Cornell Univer- 
sity, the Museum of Comparative Zoology, and the United 
States National Museum; and from the personal collections 
of Mr. Charles Robertson of Carlinville, Illinois, Dr. C. H. 
Kennedy of Ohio State University, and Dr. W. M. Wheeler 
of the Bussey Institution, Harvard University; as well as 
that which we had in our own possession. We have been 
particularly fortunate in being able to study the stylopized 
specimens accumulated at the United States National 
Museum by Dr. W. D. Pierce and thus to connect our own 
identifications and records with his extensive lists. To the 
authorities of these institutions and to the workers who 
have so kindly lent or given us material, we are very grat- 
eful. 
In the following list valid records are given in heavy face 
type, synonyms or records based on misidentifications in 
italics. References cited only once are given in full in the 
text, those used in several instances are placed in the bi- 
bliography. The words “male” or “female” invariably refer 
to the host, the signs $ or 2 to the parasite. $ e represents 
the exuvium of a male Strepsipteron, $ p the puparium of 
the same. We record the position of the parasite by giving 
the number of the abdominal tergite under which it is found 
and the letter “R” or “L” for the right or left side respec- 
tively. In the few cases in which the parasite was situated 
under a sternite rather than a tergite, the letters “st” follow 
the number of the segment. The other abbreviations are 
self-explanatory. Needless to say, our re-assignment of host 
records, in particular those of Pierce, is based upon an 
examination of the specimens in question.
