In the discussion following this paper, Mr. H. R. Carter pointed out 

 that if development from egg to adult takes sixteen days, there is no 

 need to oil until the larvae are reaching maturity.

 Waterst., with further Notes on the Genus. — Trans. Ent. Soc, 

 London, 1920, pt. 3-5, 21st April 1921, pp. 414-416, 1 fig. 



The female of Chiastopsylla godfreyi, Waterst., is described from 

 Cape Colony, where it infests various small mammals. A key is 

 given to the fleas of the genus, Chiastopsylla, Rothsch.

 d'Alfort, xcvii, no. 2, 30th January 1921, pp. 58-61. 



These observations are based on a number of cases of dermatitis in 

 horses that were caused by ticks, Ixodes ricinus. In severe cases, 

 numerous cutaneous lesions are produced, which merge into large, 

 hairless, irritable patches that are slow to heal. When horses are 

 obliged to cross infested land they should be protected with a wash 

 consisting of a tepid solution of cresyl, or rubbed down with a sponge 

 dipped in benzine and then wrung out so as to contain only the vapour. 

 Sulphur fumigation is the best curative method ; thirty minutes in 

 the disinfecting chamber rids the animals of all ticks.

 Hist. Nat., Paris, 1921, no. 1, pp. 53-59. 



The following Diptera, among other insects, were found in an ex- 

 amination of cesspools in the Paris region: Fannia incisurata, Zett., 

 F. scalaris, F., Tychomyza fnsca, Macq., Limosina fulvipes, Meig., 

 L. minutissima, Zett., and Scatopse notata, L. It was at first thought 

 that these two species of Fannia were probably the same with two 

 different types of males, but breeding experiments proved them to 

 be two distinct species.

A brief account is given of the bionomics of Slomoxys calcitrans, L. 

 During 1920, the first individuals in the vicinity of Paris were noticed 

 between 16th and 21st June. In Brittany, this fly is particularly 

 abundant in iVugust. There are apparently two generations a year, 

 the second being the more important. Among natural enemies of 

 Stomoxys are Nasonia brevicornis. Ash., Tromhidinm miiscarmn, and 

 various fungi. Remedial measures include cleansing stables with 

 1 per cent, cresyl solution and proper disposal of manvu'e.

A key is given to the French species of Culex. Those dealt 

 with are C. pipiens, L., C. laticincius, Edw., C. hortensis, Fie, and 

 C. apicalis, Adams {pyrenaiciis. Brolemann).
