^GOPHAGAMYiA *, gen. nov. 



Resembling and allied to Silvias, Mg., but distinfjidshed b)j 

 the absence of a frontal callus in the ? , by tlie proboscis being 

 slender and elongate, and by the first and fourth posterior cells 

 in the wing being closed before reaching the margin. Distin- 

 guished from Scione, Walk., by the eyes not being hairy nor 

 the face conical. Distinguished from Bouvierella t> Surcouf, 

 in which the first and fourth j^osttrior cells in the iving are 

 also closed, by the absence of a frontal callus in the ? , bij the 

 proboscis being slender and elongate, ant terminated by narrow, 

 elongate labella {instead of being short and having large 

 labella), by the smaller antennae — especially the less elongate 

 third Joint, and by the first posterior cell in the wing being 

 closed a relatively long way from instead of close to the hind 

 margin, the stalk of the first posterior cell being two or three 

 times as lung as, instead of approximately equal in length to, 

 onlg slightly longer or even shorter than that of the fourth 

 posterior cell. — Body Tabanus-Zi/i-e in shape. Eyes meeting 

 together above in J ; front in ? of moderate breadth, its sides 

 parallel ; facets ?n front portion of eyes of (J not conspicuously 

 larger than those behind; ocelli present. Proboscis and pa/pi 

 slender, former elongate and prominent, projecting downicords 

 and forwards, or {i7i (^ ) sometimes horizontal, not thickened at 

 base ; labella long and narroiv. Palpi small, in J linear and 

 horizontal or slightly curved upwards, terminal joint in ? 

 elongate, somewhat sivollen at base then bent downwards and 

 acicular. Antenna short, especially first and second joints, 

 third joint lanceolate in pjrojile, ivithout any projection on its 

 upper margin; terminal portion of third joint indistinctly 

 annulate, composed of four annuli. Jflngs hyaline ; first 

 posterior cell with a long stalk, i. e. closed 06 to 0*75 mm. 

 before reaching hind margin ; fourth posterior cell closed either 

 just before margin, or at any rate nearer to margin than point 

 at ivhich first posterior cell is closed ; anterior intercalary 

 vein, though sometimes complete, often terminating abruptly 

 before reaching margin.

 of the typical species taken by i)v. Aders in Zanzibar -weiv I'onnd on 

 goats) ; fiina, a iiy.

 (>iglio-To9,tlio habitat of which is the Seychelles Is., the eight species of 

 Bouvierclla at present known are contiiud to Madagascar.
