27.— MACRONYCHIA, Rud. ~ C ^^V^r^ K ^ ^ 



Gen. ch. — Eyes nude, somewhat widely separated in both sexes ; 

 fronto-orbital bristles reaching to the roots of the antennae, and partly 

 in a double row in the male as well as in the female ; antennae with 

 the second joint rather thickened and setose, the third joint not much 

 longer than the second ; arista bare ; cheeks wide, and clothed with 

 fine scattered hairs ; facialia bare ; vibrissae with^two long decussating 

 bristles, placed some way above the epistome ; abdomen ovoid, and 

 somewhat flattened in the male, and elongated with a projecting horny 

 oviduct in the female ; the first segment is nearly as long as the 

 others, and there are no discal setae; wings with the fourth longitudinal 

 vein bent at a sharp angle, and with a cubital appendix ; legs having 

 large tarsal claws and pulvilli in both sexes.

Colour yellowish-grey ; forehead prominent ; fx'ontal stripe black, rather wider 

 than the sides of the frontalia, which, like the cheeks, are white with black re- 

 flections ; antennae black ; arista thickened to nearly the middle ; palpi black ; thorax 

 with thi'ee wide stripes, the middle of which is trifid, and the outer ones maculi- 

 form ; the outer dorso-central bristles are three in number behind the transverse 

 groove ; scutellum yellow-brown with a reddish tinge ; abdomen grey, with three 

 reddish-brown triangular spots on each segment, the bases of the triangles being 

 backwards ; legs black. This species, which is very variable in size, is rare ; Mr. 

 Dale has one in his collection. 



T. cylindrica, Fin., has been recorded as a British species ; I have not seen 

 a specimen, and, from Zetterstedt's description, I do not think it will belong to thi; 

 genus.

 a few hairs on their lower part ; vibrissae seated near the sides of the
