A New Insect Enemy of the Peach.- Science, Lancaster, Pa., xliv, 

 no. 1148, 29th December 1916, pp. 924-925. 



The subject-matter of this paper deahng with the life-history of 

 Cydia {Laspeyresia) molesta has already been abstracted [see this 

 Review,^Sev. A, v, p. 757]. 



It is requested that the presence of this pest on peach or other fruit 

 trees should be reported to the Department of Agriculture, Bureau of 

 Entomology. It is not at present thought to have spread beyond the 

 District of Columbia and the adjoining territory in Maryland and 

 Virginia. 



Smith (H. S.). The Habit of Leaf-oviposition among the Parasitic 

 Hymenoptera. — Science, Lancaster, Pa., xliv, no. 1148, 29tli 

 December 1916, pp. 925-926. 



An investigation of the life-history and habits of the Chalcid, 

 Perilampus hyalinus, a hyperparasite of the fall webworm {Hyphanlria 

 cunea) is here described. The first stage larva or planidium crawls 

 about on the outside of the caterpillar and later bores its way into the 

 body cavity, there swimming about freely until the larva of the 

 primary parasite, either Hymenopterous or Dipterous, is found. 

 When it has gained entrance into this host, it remains quiescent until 

 the primary parasite is full-fed and has made its exit from the cater- 

 pillar to pupate. The planidium then finds its way to the exterior of 

 its host, after which it feeds as an ectophagous parasite in the normal 

 way. The oviposition habits of this parasite have only recently been 

 discovered. Several adult female Perilampus were captured hovering 

 about oleanders infested with Aphis nerii and fed upon Chrysopa. 

 These were placed in vials, each with an oleander leaf bearing egg- 

 clusters of Chrysopa, and were observed to oviposit directly on to the 

 leaves. The eggs are numerous, one female depositing fifty-two in one 

 day. They hatch in seven to ten days and the first stage larva is of the ' 

 planidium ty]3e. It is active at first, crawling rapidly about, but later 

 attaches itself to a leaf by the caudal end, standing out at right angles 

 to the surface, where it awaits the approach of a Chrysopa larva to which 

 it attaches itself by means of its numerous hooks. The advantage 

 gained by this habit from the standpoint of the species infesting 

 Chrysopa is difficult to understand, but in the case of P. hyalinus and 

 other species of similar habits, as well as in the case of those infesting
