Bathythrix pimplae How., Adistola americana How., Otacustes periliti 

 Ashm., Habrocyiiis thyridopterigis Ashm., Pezomachus msolitus How., 

 Spilochalcis debilis Say, Eupelmus limneriae How., Dibrachys boticheanus

A number of scavengers were reared by Dr Howard from the pupae 

 or masses of cocoons. The list is as follows : Helicobia helicis Towns. 



Fig. 4 DIBRACHYS BoucHEANus: a, larva; ^, pupa; <:, adult female — greatly enlarged; </, head 

 of larva; «■, antenna of adult — still more enlarged (after Howard; U» S. Dep't agriculture, Divi- 

 sion entomology. Tech. ser. no. 5, 1897). 



Sarcophaga species, Phora nigriceps Loew, Phora incisuralis Leow, Phora 

 Jasciata Fall., Phora agarici Lintn., Limosina species, Ho?7ialoinyia scala- 

 ris Fabr., Gaurax anchora Loew, Neoglaphyroptera bivittata Say and 

 Diplosis species. This and the preceding hsts illustrate in a remarkable 

 degree the large number of forms that may depend more or less upon 

 one species, and afford interesting examples of the relations that may 

 exist between various insects. 



In addition to these, a Eulophid was reared in some numbers from 

 the cocoons of Notolophiis by Dr Lintner in 1883 and 1884. A der- 

 mestid beetle, Perijiiegatoma variegatum Horn, has been recorded in 

 Insect life as a very effective destroyer of the eggs of Notolophtis in 

 California. The wheel bug, Prionodus cristatus Linn., is said to prey 

 upon the larvae in the southern states. The present season a mite, a 

 species of "■ Rhyncholophiis^ was observed eating the contents of many 

 eggs.
