REPORT OF STATE ENTOMOLOGIST, 1898 171 Bathythrix pimplae How., Adistola americana How., Otacustes perilitiAshm., Habrocyiiis thyridopterigis Ashm., Pezomachus msolitus How.,Spilochalcis debilis Say, Eupelmus limneriae How., Dibrachys boticheanusRatz., Elachistus cacoeciae How., Elasmiis atratus How., Syntomosphy-riim esurus Riley and Asecodes albitarsis Ashm. A number of scavengers were reared by Dr Howard from the pupaeor masses of cocoons. The list is as follows : Helicobia helicis Fig. 4 DIBRACHYS BoucHEANus: a, larva; ^, pupa; <:, adult female—greatly enlarged; </, headof larva; «?, antenna of adult—still more enlarged (after Howard; U» S. Dept agriculture, Divi-sion entomology. Tech. ser. no. 5, 1897). Sarcophaga species, Phora nigriceps Loew, Phora incisuralis Leow, PhoraJasciata Fall., Phora agarici Lintn., Limosina species, Ho?7ialoinyia scala-ris Fabr., Gaurax anchora Loew, Neoglaphyroptera bivittata Say andDiplosis species. This and the preceding hsts illustrate in a remarkabledegree the large number of forms that may depend more or less uponone species, and afford interesting examples of the relations that mayexist between various insects. In addition to these, a Eulophid was reared in some numbers fromthe cocoons of Notolophiis by Dr Lintner in 1883 and 1884. A der-mestid beetle, Perijiiegatoma variegatum Horn, has been recorded inInsect life as a very effective destroyer of the eggs of Notolophtis inCalifor
