attribute to the bite of this fly. In some cases of long standing the 

 disease is responsible for an enfeebled condition, but does not apparently 

 cause death. Some individuals recover, but with old people the con- 

 dition persists until death. It is said that repeated bites are necessary 

 before the disease is contracted ; and the fly is said not to enter houses. 

 The clearing of one area of dense and badly infested forest has rendered 

 it a fairly safe district. 



Patton (W. S.). Notes on the Myiasis-produeing Diptera of Man and 

 Animals. — Bull. Ent. Res., London, xii, pt. 3, November 1921, 

 pp. 239-261, 2 plates, 2 figs. 



Present information regarding the myiasis-produeing Diptera is 

 very incomplete, and it is with the object of extending the study of 

 these flies from other parts of the world, particularly from Malaya, 

 the Dutch East Indies, China, Japan, Australia and tropical America, 

 that this useful summary is compiled, partly from the author's own 

 observation and partly from the works of Rodhain, Bequaert, Roubaud, 

 and others. The flies most usually causing myiasis in India are 

 Chrvsomyia hczziana, VilL, which is also the most important myiasis- 

 produeing Calliphorine of Africa [R.A.E., B, ix, 53, 103], C. mega- 

 cephala, F., Lucilia argyyicephala, F., Sarcophaga sp., Aphiochaeta 

 xanthina, Speis., and A. nifipes, Meig. 



The myiasis-produeing Diptera, including those producing specific, 

 semi-specific and accidental myiases are classified ; keys are given to 

 the genera of the Oestrinae from Rodhain and Bequaert, and to those 

 of the CuTEREBRiNAE, and also one for the identification of some of 

 the larvae of myiasis-produeing Diptera, chiefly Muscids. Notes are 

 given on many of the species concerned and on methods of rearing 

 larvae for identification purposes. 



Edwards (F. W.). A Revision of the Mosquitos of the Palaearctic 

 Region. — Bull. Ent. Res., London, xii, pt. 3, pp. 263-351, 18 figs. 



In this revision the geographical limits adopted are those most 

 usuaHy given to the Palaearctic Region, viz., Europe, North Africa 

 (as far south as the tropic), the Atlantic Islands, Asia Minor, North 

 Arabia (including the head of the Persian Gulf), North Asia (as far as 

 the Himalayas), North China, and Japan. No mosquitos have yet 

 been recorded from Iceland. The mosquito fauna is fairly homo- 

 geneous over the greater part of the area, but there are two parts that 

 would seem to be better classed in the Oriental region. In the area 

 round the head of the Persian Gulf there is a very large, perhaps 

 predominating, admixture of Oriental forms, while in the southern 

 islands of Japan, at least as far north as Tokio, the fauna appears to 

 be almost purely Oriental. 



The number of species of mosquitos found in all is ninety-four, and 

 of these seventy may be said to comprise the true Palaearctic fauna 

 (though a number of them spread into adjoining regions), while the 

 remainder are intrusions from the Oriental and Ethiopian regions. 

 There are considerable differences between the North European and 

 Mediterranean faunas. The North European shows very strong 

 affinities to the Nearctic fauna, and a considerable number of the 

 species seem to be common to both Europe and North America, while 

 others have obviously representative forms in the two regions. Of the 

 former nearly all the species are already known to occur throughout
