Stylopized Vespidas
STYLOPIZED VESPIDE7
BY GEORGE SALT^ AND JOSEPH BEQUAERT~
It is becoming increasingly difficult to prepare a complete account of the various insects infested with Strepsiptera. Many of the early writers on these parasites gave lists of hosts without stating definitely whether they had them- selves seen stylopized specimens or whether their records were copied from earlier workers. Taxonomists have mentioned infested specimens in monographs of various host groups, so that many records have become scattered in articles not at all concerned with the parasites, where they are likely to be found only by a student of the hosts. Mis- takes in the identification of host species have caused much confusion; and the change of names, which seems inevitable in taxonomic revision, has greatly complicated the existing lists.
As one of us (J.B.) has been for a number of years interested in the Vespidse, while the other (G.S.), in the course of studies on stylopization, has found it necessary to keep lists of stylopized wasps, we have thought that it would be useful to publish jointly an annotated list of the Vespidse known to be infested with Strepsiptera. From the data contained in our list we have been able to draw several con- clusions which are of some interest and importance to the general subject of the inter-relation of parasite and host. We have examined stylopized material mainly from the Academy of Natural Sciences of Philadelphia, the American Museum of Natural History, the Boston Society of Natural 1 Contributions from the Entomological Laboratory of the Bussey Institution, Harvard University, No. 305. 2 Department of Tropical Medicine, Harvard University Medical School.

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 8 or 2 to the parasite. 8 e represents the exuvium of a male Strepsipteron, 8 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.
