I9I7-] E. Brunetti : Diptcra of the Simla District. 85 



Mclanostoma mcllinum, Linn. 



Melanostoma scalare, Fab. 

 Melanostoma orientale, Wied. 



For descriptions see Verrall, British Flies, VIII (Syrphidae), pp. 309 

 and 311, and Wied., Auss. Ziveifl., II, p. 139. 



The specimens originally referred by me to scalare are certainly 

 orientale, Wied., and in my second paper on Oriental Syrphidae ' 

 I have suggested that Wiedemann's species is only a variety of 

 mellinum. Assuming the identity, the species has been taken at 

 Theog., 27-iv-07 ; Simla, 24-iv-07 and Matiana^ 28 — 30-iv-07. 



Mclanostoma ambiguum, Fin. 



For description see Verrall, British Flies, VIII (Sjrphiclae), p. 304. 



A single cf , undoubtedly of this species, from Matiana. 



Melanostoma dubium, Zett. 

 For description see \'errall, British Flies, VIII (Syrphidae), p. 307. 



Erroneously recorded by me from Matiana. See note under 

 Platychirus alhimanus on previous page. 



Sphaerophoria, St. Farg. 



As noted in my second paper on Oriental Syrphidae the species 

 in this genus offer exceptional difificulties, beyond the two common 

 ones, scutellaris, F. and javana, Wied. In that paper I described 

 four " forms," all occurring in the Simla District, to three of which 

 provisional names were given. These are : Form r, flavoabdomi- 

 nalis, Simla, 6— 8-V-07 ; Form 2, Simla. 6 — 8-V-07 ; Form 3, 

 nigritarsis, Matiana, 28— 30-iv-07 ; Theog, 24-iv-07 ; Kodiala, 

 Simla District ; Form 4, viridaenea, Simla, 16-V-09 ; Theog, 

 2-V-07. 



Rhingia laticincta, Brun. 



Rec. hid. Mas. II, p. 58. 



Simla, 7-V-10 ; Phagu, i8— 21-V-06. Occurs also at Mussoorie 

 and Darjiling.
