as it lies in the field and not in places in which it has been 

 collected. Miisca ijattoni, Aiist. (1910), is abundant in Madras 

 throughout the year and breeds regularly in the heap of cow- 

 dung kept on the Sewage Farm of the King Institute, Guindy, 

 Madras. It never lays its eggs in isolated patches of cow-dung. 

 Each egg is laid singly. The larvae, unlike those of gibsoni, 

 never migrate from the dung, but pupate in it. The flies are only 

 seen on cattle and horses, and they vrovvy PhUaematoviyia insignis 

 and Stomoa'ys calclfraiis in much the same way as Musca gihsoni. 



Miisca conce.iifrons, Thomson (1868), is common in Madras 

 throughout the year, but has not been found in any of the hill 

 stations. The oviposition is similar to that of Miisca gihsoni and 

 both sexes feed on cattle. 



Musca hezzii, sp. n. The male of this handsome fly was first 

 found at Kodaikanal in 1910 by Mrs. Patton. Two years later 

 Cragg found it in Kolagni, in the Nilgiri Hills, and was able 

 to follow its life-history. It is numerous only during the middle 

 of the year and was rarely seen at Kodaikanal in September, and 

 the authors have never seen it in the plains. The fly closely 

 resembles Fhilaematomyia gurnei. It is larviparous and its 

 reproductive habits are similar to those of M. corvina, F. (ovijjara, 

 Portch.), of Europe. Only one young larva is produced at a birth 

 and this passes through the next two phases exactly like the 

 larvae of gibsoni or imttoni. On two occasions a large egg was 

 laid instead of the larva, one of these kept in moist dung did 

 not hatch and the fact is regarded as abnormal.

The first known species of this genus, insignis, was described 

 by Austen in 1909 from several localities in India. Since that 

 time it has been recorded from Ceylon, Borneo, Sokotra, Senegal 

 and the Congo Free State. It appears to be a common fly in 

 the tropics and in' Madras, at any rate, it is the commonest 

 biting fly found on cattle. In 191(3 Brunetti described a second 

 species, lineata, erecting for it, however, a new genus PristirJnjn- 

 chomyia. The authors regard this fly as properly belonging to 

 Austen's genus and describe the male of lineata which was not 

 known to Brunetti. This species is not uncommon at Saidapet 

 in cold weather, but is never so numerous as insignis. In the 

 hot weather it has been found at Kodaikanal. The authors, after 

 careful observation, are able to say with certainty that it is not 

 able to make a wound for itself, though it is a true blood-sucker. 

 Philaern atomy ia gurnei, Patton and Cragg, is described at 

 length. It appears to be a hill species and is somewhat rare. 

 It was proved by dissection to be oviparous. A specimen taken 

 from a cow in the grounds of the King Institute, Saidapet, is 

 regarded as having been imported from the hills with the animal. 

 The remainder of the paper is devoted to a discussion of the 

 general characters of the genus Philaeniatomijia.
