TACHINIDAE OF ORIENTAL REGION 73 



Eyes haired. Palpi brownish black. Head with normal profrons and moderately 

 wide parafacials (the parafacial at mid-height subequal in width to length of third 

 antennal segment). Antennae of medium length, third segment about twice as 

 long as second segment. Abdomen black with narrow basal bands of pale pollinosity 

 on T3-T5, the pollinose bands of T3 and T4 incomplete medially, the colour of the 

 pollinosity mainly bright silver but becoming coppery golden brown towards the 

 mid dorsum .......... annularis Villeneuve 



Description of New Species of PHYLLOMYA Robineau-Desvoidy 



Phyllomya gibsonomyioides sp. n. 



(J. Head ground colour mainly black but appearing reddish brown in some lights on genae 

 and parafacials, interfrontal area dark velvety brown. Head virtually holoptic, eyes so strongly 

 approximated that upper part of interfrontal area completely obliterated (Text-fig. 69), pre- 

 vesical setae and proclinate orbital setae absent (head form resembling Gibsonomyia) . Occiput 

 flat. Upper ends of postorbits evanescent, the rows of exceedingly long fine postocular setae 

 inserted adjacent to the upper posterior eye margins. Parafacial hair present on most of the 

 parafacial surface. Genal dilation weakly developed. Ocellar setae very long and very fine. 

 Vibrissae strong. Antennae black; third segment twice as long as second segment; arista 

 bushy long-plumose (Text-fig. 69), total width in profile including the plumosity conspicuously 

 more than width of third antennal segment. Palpi brownish. Thorax black with thin silvery 

 pollinosity, the pollinosity most evident on pleural regions, prescutum and humeral calli, 

 very thin and inconspicuous on scutum and scutcllum ; in some lights prescutum showing a 

 broad black median vitta and paired sublateral black spots. Three post dc setae. Two stpl 

 setae. Wings with a very faint brownish tinge to naked eye. Legs black ; fore tibia with 

 two pv setae; mid tibia with two ad setae; hind tibia with three ad setae and two pd setae, 

 and without pd preapical seta. Abdomen blackish, without definite bands of pale pollinosity 

 and appearing almost uniformly black to naked eye; in some lights the sides of Ti + 2 and 

 T3 and more or less all of the remaining tergites showing a thin coating of bluish grey or silvery 

 pollinosity, and Ti + 2 and T3 each showing a large brownish black median triangle that 

 contrasts with the paler pollinosity. Abdominal shape elongate fusiform (Text-fig. 109); 

 Ti + 2 without discal setae. Length 9-10 mm. 



9- Similar to <$ except for dichoptic head with a pair of prevertical setae and two pairs of 

 proclinate orbital setae. Abdomen with a rather even coating of very thin bluish grey polli- 

 nosity except for a median parallel-sided or posteriorly tapering black vitta on Ti + 2, the 

 pollinosity not changing much in appearance with direction of light (except for being more 

 evident anteriorly than posteriorly on tergite venters). 



Holotype $, India. In British Museum (Natural History), London, ex coll. 

 Brunetti. 



Paratypes. India: i £, West Bengal, Darjeeling, vi.1917; 1 <$, Himachal Pradesh, 

 Simla, 20-28. vii.1918; 1 $, Himachal Pradesh, Simla, 6.viii.ic;i8; 5 $, no further 

 data (two without head, one without abdomen). 



All paratypes in BMNH ex coll. Brunetti. Those with no locality data other 

 than 'India', and the holotype, are almost certainly from either Himachal Pradesh 

 or West Bengal, whence much of Brunetti's Indian material came. A male from 

 either the Simla or the Darjeeling specimens has not been selected as holotype, 

 despite the more complete data, because each lacks important features (the Darjeel- 

 ing male has no mid legs and the Simla male has lost both third antennal segments 

 and therefore the aristae).
