yellow. Third abdominal segment of the male with a row of bristles. Wings with- 

 out anal stripe, but in the male a grey round spot at the tip of the anal cell. 



The synonymy with persicae seems to me very certain ; that with maculigera 

 appears to be proved by lyoew's label in the Museum at Vienna, of which Mr. Frog- 

 gatt speaks in his Report. 



There are several specimens in the collection caught on board ship, ten miles off 

 Masulipatam, Madras coast, 4— 5th June 1908, by C. Paiva (-\i~-~jl-)- This is 

 a very good example of the transport of fruit flies by shipment. Another specimen 

 is from Paresnath, West Bengal, 4300 ft., 9-iv-i909 {Annandale) (--ff-), and another 

 from Pusa, June igo8 (-tI")- 'T'he species is already recorded from several places 

 in India, Doleschall has it from Amboina and Enderlein from Sumatra.

A middle-sized species, varying in colouring from ferruginous to dark brown with 

 distinct yellow markings on the thorax and with hyaline wings filled with brown only 

 on the fore border and at the anal cell. 



This species is very variable in size and colouring, as already stated by Mr. Frog- 

 gatt. The male shows the row of bristles on the third abdominal segment, and the 

 anal stripe of the wing dilated at the tip. Frontal spots distinct ; vertical bristles 

 yellow; posterior bristles of the thorax darkened, often almost black. In dark 

 specimens the yellow streaks of the thorax and the yellow scutellum are very striking. 



This is a widely spread species, since we find records from India, Ceylon, Java 

 and Amboina, but it is very doubtful if the species has ever been exactly recognized. 

 The fermgineus of Macquart is a different species, and the maculipennis of Doleschall 

 has been erroneously placed here by Van der Wulp. 



In the collection are many specimens from Calcutta, all caught in May, and one 

 fed on rotten mangoes. Other examples are from Bangalore, S. India; Mergui; 

 Sikhim; Tenasserim, Lower Burma; Sylhet; Shillong; Kurseong, 5,000 ft., E. 

 Himalayas (A^. Annandale)) Rajmahal, Bengal, ö-vii-og ; Katihar, Purneah district, 

 N. Bengal, 15-v-io ; Peradeniya, Ceylon, i6-iv. There is also a specimen from 

 Batavia, determined by Prof. Meijere. 



To judge from a specimen from Peradeniya, Ceylon, labelled by Mr. Froggatt 

 himself, Dacus tryoni is synonymous with the present species; the specimens bred 

 from fruits which I have received from Gospad district, N. S Wales, through the 

 kindness of Mr. Froggatt, approach the following variety: —
