Pierce (1909) predicted that the Blattoidea and the Grylloidea would be the only groups of the Orthoptera which would be parasitized by Strepsiptera. Essig (1926) made the statement that certain cockroaches are among the hosts of Strepsiptera. E. F. Riek (personal communication, 1952) found a strepsipteron in a late nymph of _Cutilia_ sp. from Waroona, Western Australia; he wrote us, "The female parasite is extruded between a pair of sternites towards the base of the abdomen and appears to belong to the family Halictophagidae." This is the only record that we have been able to find of a strepsipteron parasitizing cockroaches. Order HYMENOPTERA PREDATORS AND PARASITES OF COCKROACH EGGS Wasps from at least six families of Hymenoptera have been recorded as developing on cockroach eggs. All the Evaniidae are presumed to be parasitic in the egg capsules of cockroaches (Clausen, 1940; Townes, 1951), although hosts for many of the described species have yet to be discovered. The presence of evaniids in dwellings indicates the presence of cockroaches (Gross, 1950). At times these wasps may become a nuisance; a family in Worthington, Ohio, complained of the evaniid wasps that they found on the windows and in other areas of their home, but they were apparently not annoyed by the oriental cockroaches in the basement (Edmunds, 1953). The known parasites of cockroach eggs are listed below with summaries of their biology. Family EVANIIDAE =Acanthinevania princeps= (Westwood) _Synonymy._--_Evania princeps_ [Dr. H. Townes, personal communication, 1956]. _Natural host._--Cockroach eggs, Australia (Froggatt, 1906). =Brachygaster minutus= (Olivier) _Synonymy._--_Evania minuta_ Olivier [Kieffer, 1920]. _Natural hosts._--_Blattella germanica_, Europe? (Schletterer, 1889; Kiefer, 1912; Crosskey, 1951.) _Ectobius lapponicus_, Europe? (Schletterer, 1889; Kieffer, 1912; Crosskey, 1951.) _Ectobius panzeri_ var. _nigripes_? Great Britain (Blair, 1952): This is a presumptive record. The wasp was collected at Niton and Headon Hill, Isle of Wight, an area in which this variety of _E. panzeri_ was the only species of cockroach known to occur. _Ectobius_ sp., England (Cameron, 1955, 1957): Natural History Museum records. Adult wasps have been collected on _Asparagus officinalis_ Linnaeus (Schmiedeknecht _in_ Schletterer, 1889; Crosskey, 1951). Thompson's (1951) citation of records of _B. minutus_ and _Evania appendigaster_ from _Blatta orientalis_ and _Blattella germanica_, and Cameron's (1957) citation of these records and one from _Ectobius lapponicus_, all attributed to Kadocsa (1921), are almost certainly in error. Kadocsa (1921, p. 33) listed these wasps as egg parasites of cockroaches but not necessarily in Hungary and did not name specific cockroach hosts.
