1913- 1 E. Brunetti : Diptera. \~jj 



ish, arista plumose. Proboscis rather long with large labella ; 

 palpi long, cylindrical, all pale ^^ellow. Back of head blackish in 

 middle. Three pairs of fronto-orbital bristles, the upper (and 

 strongest) pair nearly on vertex; a pair of ocellar, a pair of small 

 central vertical and a strong vertical bristle situated on the abso- 

 lute margin, behind the corner of each eye. Smaller post-vertical 

 bristles are present. 



Thorax. — Brownish ; maculated with numerous small light grej" 

 spots and short zigzag lines, the most conspicuous of the latter 

 beginning on each side of the anterior margin and passing over the 

 shoulder, below which it encloses at its end a round black spot. 



Bristles: 3 dorso-central, i humeral, i post-humeral, i pre- 

 alar, i sternopleural ; numerous acrostichal bristles. The scutel- 

 lum with one pair of post-basal (marginal) and a pair of widely 

 separated apical ones. Scutellum generally brown with grey 

 marks as the thorax, but all the marks are variable, so that in 

 some specimens the ground colour may be considered light gre}^, 

 and the markings brown. 



Abdomen --Dark brown. The ist segment mainly light grey 

 with a triangular brown mark at base, and the hind margin 

 brown s])otted. Each of the remaining segments bear a pair of 

 large light grey spots on the front border, approximately semi- 

 circular (emarginate on lower outer part) and bearing a distinct 

 round black spot in each. Posterior margins of segments with 

 bristles ; surface of abdomen generally shortly pubescent. Belly 

 dark, with grey markings. 



Legs. — Pale yellow ; posterior femora (especially hmd pair) 

 mainly brown or brownish for basal three-fourths, the intensity of 

 the colour variable; bristles on lower si les of all the femora, 

 longest and fewest on fore pair, weakest on hind pair. Tibiae 

 and tarsi pale yellowish or pale brownish 5'ellow, pubescent; hind 

 metatarsi more or less brownish above ; posterior tibiae with pre- 

 apical bristle, middle tibiae with a few spines at tip. 



Wings. — Blackish, with several semicircular or sub-triangular 

 pale whitish grey spots around margin and numerous smaller simi- 

 larh' coloured spots over the disc. The larger spots are placed 

 thus. An oval one on the costa (with a black spot in its middle), 

 filling the costal cell as far as the auxiliary vein. Four spots 

 on the costa, between tip of 1st longitudinal vein and tip of 

 2nd; of these,, the first three are subtriangular, the first one 

 separated further from the second than the latter is from the 

 third, and in this intervening space a small yellowish costal 

 spot, often indistinct; the fourth spot is more rounded. The 

 remaining spots on the wing margin are more or less semicircu- 

 lar and approximately uniform in size. The submarginal cell 

 has two (a large and a small one), the ist posterior cell, two 

 the upper one the smaller and more triangular; the 2nd posterior 

 cell has three, the uppermost the smallest. Behind the 5th longi- 

 tudinal vein tip there are four on the wing margin, the first im- 

 mediately behind the 5th vein tip and practically contiguous to
