The case of Chalcids feeding as external parasites of their host, 

 unprotected by their food-substance or pupal covering, has been 

 very rarely observed, though the Eulophid, Euj^lectrus comstocU, How., 

 is well-known as having this habit in relation to the cotton worm 

 '[Alabama argillacea]. Another Chalcid with similar habits is 

 Schizonotus sieboldi, Ratz., which was originally described from 

 individuals reared from Melasoma {Chrysomela) populi. The author 

 records the attack of this parasite upon pupae of M. interruphmi, Hald., 

 on alder in Pemisylvania. Both larvae and pupae of the parasites 

 were found on the ventral side of the ho.st ; there were generally 

 3 to 7 parasites on each, the beetle pupa being sucked until completely 

 dry. On pupae of M. interrupum that had been parasitised by 

 successive attacks of S. sieboldi, the minute larvae of the second 

 ■attack were found feeding on the older parasites.

Coleophora volckei, sp. n., is described from moths reared from larvae 

 •collected in California upon apple, the larvae mining the leaves and 

 ■occasionally feeding upon the fruit itself [see this Review, Ser. A,

This paper is the result of a study of many individuals of the genus 

 'Cephus reared from the stems of various grass-like plants, and is an 

 attempt to separate the species that are injurious to American cereal 

 and forage crops. The author has come to the conclusion that there 

 is only one species involved, the forms previously distinguished being 

 merely extreme varieties of the same species. A key is given to the 

 North American species of Cephus, in which the European species, 

 'C ])ygniaeus, L., is differentiated from the native American one, 

 C. cinctus, Norton. The latter has the more extended range and is 

 of far more economic importance in North America. The species 

 previously known as Cephus rufiventris, Cress. , is referred to the genus 

 -Janus.
