 The bulk of the information contained in this bulletin has previously 

 been noticed [see this Review, Ser. A, iv, p. 189]. The repellent 

 mixture described consists of 1 part powdered lead arsenate and 

 5 parts finely ground sulphur. A simple screen wire sifter is recom- 

 mended for small areas, and power machines for use on large acreages 

 are described and ilkistrated.

Life-histories are given of the various parasitic and predaceous 

 insects attacking the Melolonthid beetles of the genus Lachnosterna 

 (PhyllopJiaga). Parasites of the larvae include : Tiphkt punctata, Rob. , 

 T. transversa, Say, T. inornata, Say, and T. vulgaris, Rob. These 

 wasps are themselves parasitised by the Bombyliid flies, Exoprosopa 

 fascipennis, Say, E. puehlensis, Jaenn. , Anthrax iMrvicornis, Coq. , and 

 a Rhipiphorid beetle, Macrosiagon jyectinatus, F. 



Other Hymenopterous parasites of Lachnosterna are : Elis quinque- 

 cincta, F., E. atriventris, Gah., E. interrupta, Say, E. obscura, F., and 

 E. illinoisensis, D.T. 



Tachinid and Dexiid parasites include Microphthalma disjuncta, 

 Wied., M. pruinosa, Coq., Ptilodexia harpasa, Wlk., P. dbd.ominalis, 

 Desv., Myocera cremides, Wlk. ? and Prosena (Mochlosoma) lacertosa, 

 Wulp. Predaceous insect enemies of the larva comprise the larvae 

 of a number of Asilids : Promachus vertebratus, Say, P. fitchi, 0. S., 

 P. bastardi, Macq., Erax maculatus, Macq., E. aestuans, L., E. cinera- 

 scens, Bell, Deromyia winthemi, Wied., D. discolor, Lw., D. umbrina, 

 Lw., Asilus paropus, Wlk., A. lecythus, Wlk., Ceraturgus cruciatus. 

 Say, Proclacanthus milberti, Macq., and Coenomyia pallida, Say, and 

 two Tabanid larvae, Tabanus atratus, F., and T. sulcifrons, Macq. 



Among Coleoptera the larvae of the Carabids, Harpalus pennsyl- 

 vanicus, Dej., H. caliginosus, F., Calosoma calidum, F., C. scrutator, F., 

 C. lugubre and Chlaenius tomentosus, Say, probably all prey upon 

 white grubs. A number of occasional predaceous enemies such as 

 ants, mites and crickets are also mentioned. 



Parasites of the beetle are the Ortalid flies, Pyrgota undata, Wied., 

 and P. valida, Harr., both bred from a large number of species ; the 

 Tachinid flies, Cryptomeigenia thelitis, Wlk., C. aurifacies, Walt., 

 Eutrixoides jonesi, Walt., Eutrixa masuria, Wlk. [exilis, Coq.) and 

 Biomyia lachnosternae, Towns. 



The following have also been recorded, but their value as enemies 

 is doubtful : Sarcophaga prohibita. Aid., S. tuberosa Pand., var. 

 sarracenioides, Aid., S. cimbicis, Towns., S. helicis, Towns., S. utilis. 

 Aid., S. falculata, Pand., and possibly Fannia canicularis, L. Spider 

 enemies include Lycosa helluo, Wakn., Xysticus gulosus, Keys, and 

 Plectana stellata, Hentz. 



Particulars are also given of diseases caused in white grubs by 

 Nematodes, Protozoa, bacteria and fungi, with a list of the birds, 

 mammals and Amphibia that prey upon them.
