Var. mangiferae, Cotes.

 Cotes, Ind. Mus. Notes, iii, 17, fig. \_Dacus\ (1893); Maxwell- Lefroy, Indian Ins. Pests, 170, figs. 

 igi-92 [Dams] (1906) and Mem. Dept. Agric. India, i, 227. 129, fig. 71 [Dacus] (1907) both as 

 ferrugineus, F. 



This variety very much resembles the lighter coloured specimens of ferrugineus , 

 from which it is distinguished by the paler colouring and by the shape of the abdomen, 

 which is pointed at the end and distinctly narrower than the thorax. The dark 

 brown spots of the frons are often indistinct. Thorax always pale ferruginous, the 

 yellow markings therefore less distinct ; thoracic bristles yellow. Wings with an 

 indistinct narrow greyish margin on the fore border, often quite hyaline with only a 

 small grey spot at the tip of the third vein; anal stripe also less distinct, but the 

 dark spot at the end of the anal cell in the male is present. 



In my paper of 1909 I have, with Mr. Froggatt, not distinguished this variety. 

 D. xanthodes , Brown, as described and figured by Froggatt, seems to be a closely 

 allied form; it was bred in New Zealand from larvae infesting fruits brought from Fiji. 

 It is very probable that this variety is based only on bred specimens, its 

 colouring and the peculiar shape of the abdomen depending only on immaturity. 

 There are many specimens in the collection. Two males from Calcutta (-f 1°. "ff-). 

 bred from mangoes, are co-types of Cotes. One female from Calcutta (-ff-), deter- 

 mined by Bigot as ferrugineus, is said to have been compared with specimens of this 

 species in the British Museum. Other specimens come from Hughli, Bengal (/. C. 

 Chakrahutty).

A proportionally large species, which can be easily recognized from all other 

 known Indian species by the posterior cross-vein of the wings being widely bordered 

 with brown. 



Vertical, thoracic and scutellar bristles black. Third abdominal segment of the 

 male with a row of black bristles ; anal stripe dilated at the tip, but less abruptly 

 than in the preceding species. 



This species was originally described from Hawaii, but subsequently it has been 

 found widely distributed over India and Ceylon, and this is its original home. In 

 the collection are many specimens from Calcutta, caught in April, May, June and 

 September; others from Durjhana, Nepal Terai ; Ranchi ; Jhansi, N. W. India, 

 850 ft. {Brunetti); Katihar, Purneah district, N. Bengal; Kumdhik, Nepal Terai, 

 in March; Bhogaon, Purneah district, N. Bengal, in October; Allahabad, United 

 Provinces, in August; Nepalganj, Nepal Frontier, 22-xi-ii ; Siripur, Saran, N.
