This Journal is to be a quarterly one, the subscription being 6 rupees in 

 India, 10/- foreign, and the number under review contains 211 pages and 

 numerous plates. The articles devoted to Entomology comprise two joint 

 papers by Messrs. W. S. Patton and F. W. Cragg, of the King Institute, 

 Gundry, Madras ; and two by F. M. Hewlett, Imperial Pathological Entom- 

 ologist. The first of the joint papers is entitled " On certain Hsematophagous 

 Species of the Genus Musca," and deals with four species of Musca (two of them 

 described as new to Science), which though blood-suckers, are not " biters," but 

 resort to open sores and the wounds inflicted by other " biters." The second 

 joint paper is entitled " A new species of Philsematomyia, with some remarks on 

 the genus." The drawings by Mrs. Patton represent both sexes of all the 

 species on a large scale, with figures of the egg, larvae, and pupae. The first of 

 Mr. Howlett's papers is on " The natural host of Phlebotomus minutus," which 

 he finds to be lizards of the family Gechonidse ; the other forms Part I of a 

 treatise on " Insect life-histories and Parasitism."

 Bulletin, published by the University of Columbus, Ohio. June, 1913.

This paper brings together, and summarizes the results of, a number of 

 observations on the life-histories of Syrphidz?, published from time to time in 

 the *' Ohio Naturalist," with the addition of a useful summary of the recorded 

 biology of the family and a record of the species which up to the present have 

 been captured in Ohio. Two interesting facts recorded by the author are 

 (1) that the larvae of Paragus feed on Aphids occuring on Bumex, Arctium, 

 and Carduus, and (2) that the larvae of Syrphus xanthostomus and an un- 

 determined species live inside the gall of gall-producing Aphids of the genera 

 Pemphigus and Colopha. Eight of the black and white plates are devoted to 

 illustrating details of larvae and pupa 1 , but the author would have materially 

 assisted one in studying the figures if he had used the same reference letter to 

 an anatomical detail in all figures. The economic value of many Syrphidm, 

 owing to the aphidophagous habits of the larvae, has been very little appre- 

 ciated, and consequently little studied. It is to be hoped that the present work 

 will stimulate research along these lines.
