G. hippoboscoides, n. sp. 9- Head almost 

 uniform light jellow, between the ocelli 

 tinged with brown. Eves black, bare, not 

 approximated to each other. Front broad, 

 • wider anteriorly, with jellow pollen on the 

 sides, a longitudinal callositj more whitish, 

 extending from the ocelli to the beginning 

 of the antennal prominence; in dried speci- 

 mens a variable impressed line on euch side 

 of this callositj. Antennae situated on a 

 distinct transverse prominence, j'ellow, the 

 third joint more reddish ; second joint al- 

 most annular, third tapering quite sjmmet- 

 ricallj, composed of eight annuli. Face 

 yellow, strongly protuberant, shining. Pro- 

 boscis reddish, directed forward, reaching 

 but little beyond the antennae. Palpi slen- 

 der, long, yellow, with yellow pollen and 

 abundant blackish hairs. Posterior orbits 

 wide, conspicuous, with 3'ellow pollen. 



Thorax whitish yellow below, more brown- 

 ish above, with minute, appressed, silvery 

 yellow pile; on the anterior border just a 

 trace of a slender, median, reddish line; on 

 each side a broad, indistinct reddish stripe, 

 interrupted along the transverse suture. 

 Scutellum short, as wide as the head, 

 yellow. 



Abdomen short, broad, covered with ap. 

 pressed shining silvery-yellow pile; seven 

 visible segments, the last narrow, but little 

 protruded, showing a distinct emargination. 



Legs uniformlj light jellow, the claws 

 black except at base. Spurs of moderate size 

 on middle and hind tibiae. 



Wings hyaline, with a deep brown cloud 

 exte'nding across them, including the follow- 

 ing parts: the stigma, all of the marginal 

 cell except the proximal end, all of first sub- 

 marginal, all of the second except tip, all of 

 the first posterior except posterior half o 

 the distal end, the proximal half of the discali 

 all of second basal, and middle of anal. 

 There is a characteristic small clear spot in 



the second basal, at the anterior distal angle. 

 The cloud is clearly defined behind, but fades 

 more gradually in front. The branch of the 

 third longitudinal vein shows a tendency to 

 emit a stump of a vein. In one of my speci- 

 mens the vein separating the third and fourth 

 posterior cells is obsolete for the greater part 

 of its course. 



Length 12 to 13 mm. Width across ex- 

 panded wings, 28 mm.
