Enemies of Tiphia Three species of bombyliid flies representing two genera (Exopro-sopa and Anthrax) have been reared from Tiphia cocoons. Of these,E. fascipennis Say, which was first recorded as a Tiphia parasite byDr. S. A. Forbes (26), is the most common in our rearings, althoughit would appear that none of the species are sufficiently abundant tolessen noticeably the value of Tiphia as a white-grub parasite. Iliis 70. species has been reared at the Lafayette Laboratory from Tiphia cocoonscollected in various parts of Illinois and Indiana, the adults issuingduring the month of July. Mr. H. E. Smith obtained an adult July 7,1913, from Tiphia cocoons collected at Wellington, Kansas, and E. informs me that he has also reared it from the same locality and
