Hulecoeteomyia trilineata. Leicester (1904), 

 The Entomologist, Vol. XXXVII., p. 163 (1904). 



Thorax rich brown, with three narrow golden lines, the 

 median one entire, the lateral broken before the roots of the 

 wings. Abdomen black, with pearly white lateral basal spots 

 in the female, with narrow white bands in the male. Legs 

 black, basally pale-banded, most prominently on the hind legs. 

 Fork-cells short. Male palpi about four-fifths the length of the 

 proboscis. 



" J . Head black, clothed with flat black scales and 

 numerous upright black forked scales ; there is a line of narrow- 

 curved scales, creamy yellow in colour, running down the centre 

 and along the orbital margins, and behind over the nape, 

 scattered among the flat black scales, are a few white narrow- 

 curved ones ; laterally there is a patch of white flat scales 

 succeeded by black scales, which are followed again by white 

 scales ; on the vertex, projecting forwards between the eyes, is 

 a tuft of pale golden bristles ; there are other bristles along the 

 orbital margins which are black at the base and pale at the 

 tip. Antennae with the basal segment dusky black, with small 

 black spindle-shaped scales on its inner face (in some specimens this 

 segment is ferruginous), remaining segments black ; second segment 

 black-scaled ; verticillate hairs black ; all the segments after second 

 clothed with short silky white hairs. Clypeus black, frosted. Palpi 

 yellowish-brown, of four segments ; first segment constricted in 

 the middle, fourth segment very small, clothed with black spatulate 

 scales except towards the tip, which is white-scaled. The amount 

 of this white scaling varies. In one specimen it includes little 

 more than the last segment, in another one it includes half the 

 penultimate segment. Proboscis yellowish-brown, black-scaled 

 dorsally and laterally ; beneath it is white-scaled ; about half-way 

 white scales appear laterally, and may even go right round, 

 forming a complete band. Prothoracic lobes simple, prominent, 

 white-scaled. Mesonotum dark brown, clothed with narrow- 

 curved scales, black under a hand lens, but under a two-thirds 

 power the tips appear pale golden ; there is a central line of pale 

 golden scales which forks in front of the scutellum, enclosing an 

 unsealed area ; on either side there is another line which runs 

 back about one-third the total distance ; placed a little further 

 out is another line running forwards from the scutellum and
