abdominal segments. lyegs entirely yellow; bristle-row of the front femora with 

 4 or 5 bristles, hind tibiae with well-developed row of bristles. 



Wings with the basal streaks as in the preceding species ; the yellow cross-bands 

 are similarly disposed, but the first is wholly separated from the second, owing to the 

 fact that the hyaline space between the two first bands extends to the costa. 



A female from Kohima, Assam (-^s")- 



5- Gastrozona, n. gen. 



Like the preceding, but easily distinguished by the weaker oc, the unpointed 

 third antennal joint and by the different pattern of the wings, which have also no 

 distinct costal bristle. 



Head as high as broad or higher than broad, the eyes being round or narrowed ; 

 face concave; third antennal joint rounded at the tip ; arista plumose, with more or 

 less long hairs; the chaetotaxy exactly the same as in the preceding, but the vibris- 

 sal edges without bristles and the oc. much weaker than the or. or the vt. Palpi 

 without stout bristles. Thoracic and scutellar chaetotaxy also the same ; scp. black ; 

 scutellum more flattened. Abdomen with the last segments bristly ; ovipositor 

 flattened and short. Legs as in the preceding. Wings also, but the pattern very 

 dift'erent and not unlike that of the Neotropical genus Anastrepha; the base without 

 black streaks ; small cross-vein after the middle of the discal cell ; anal cross-vein 

 non-CeratitisAAko: ; the inferior angle of the anal cell drawn out in a very narrow 

 point, longer than the second basal cell. 



Type : Tephritis fasciventris, Macquart. 



This genus seems to be allied to the recently created African genus Carpophthoro- 

 myia, Austen (Bull, entom. Research, i. 71, 1910), but is distinguished by the 

 flattened non- tubular ovipositor, the less developed costal bristle, the different shape 

 of the anal cross-vein, the want of black streaks on the base of the wings and by the 

 thorax having longitudinal in place of transverse bands. 



The Indian species before me can be distinguished as follows : — 



1 (4). Eyes not narrowed; thorax ferruginous with or without black 



longitudinal stripes ; scutellum pale yellow. 



2 (3). Thorax with two longitudinal black stripes; scutellum with an 



apical black spot ; abdomen with a single black cross-band . . fasciventris, Macq. 



3 (2) Thorax without such stripes; scutellum entirely whitish yellow; 



abdomen with two or three transverse black bands . . montana, n. sp. 



4 (i). Eyes narrowed; thorax black with ferruginous longitudinal stripes; 



scutellum shining black, with yellow spots on the sides . . melanista, n. sp. 



14. Gastrozona fasciventris, Macquart. 

 (PI. viii, fig. 16.) 



Macquart, Dipt, exot., iii. 382 (225) 4, pi. 31. f- 2 [Tephritis] (18^3) ; fasciventris m the index, 

 p. 459 (302). 



A yellow ferruginous species with two longitudinal black bands on the thorax 

 and a transverse black band on the third abdominal segment.
