Tylotuypes, gen. nov. 



This new genus is distinguished from all the others on 

 account of the third longituilinal vein ending some disfiitice 

 before the apex of tiie wing; in tliis character it agrees with 

 Diasteneura, Hend., from which it is separated by the very 

 different shape of head and antennae. There is some resem- 

 bhince witli the Ethiopian genus Tephritopyr(jota^ Ilend., 

 chieHy on account of the wing-pattern. 



Head as broad as thorax; frons flattened, l^ times as 

 broad as eye; vertex very slightly prominent; jowls very 

 narrow, less prominent above; peristoma narrow, not more 

 than \ the vertical diameter of the eye; antennal grooves 

 very short, hardly any longer than half the length of 

 the face ; ocelli wanting ; eyes broadly oval, less than 1^ 

 as long as broad, with the anterior areolets distinctly dilated. 

 Atitennse very short, not surpassing the half of the face ; 

 third joint as long as the second, oval, with a bare arista 

 inserted basally ; palpi rather long, but not dilated ; proboscis 

 small. Macroch£eta3 rather long and strong — a pair of 

 ocellar, a pair of divergent postvertical, two paiis of vertical 

 (the outer much weaker), a single pair of rather weak orbital. 



Thorax as broad as long, convex, clothed with long and 

 dense hairs; macrochsetas rather long and strong ; a humeral, 

 three notopleural (2:1), a prsesiitural, three supra-alar ; a 

 pair of dorso-central and a pair of prifiscutellar, botli rather 

 weak and Itss distinct between the long hairs ; the pleural 

 macrochaitjfi are not distinct between the hairs, only the pos- 

 terior sternopleural being long and prominent. Scutellum 

 rather convex, distinctly bilobate at end, clothed with thick 

 hairs, even longer than those of the thorax, and bearing only 

 a pair of apical niacrochaitte, which are long and diverging. 



Abdomen short and broad ; first segment narrowed at base 

 and .'^trongly dilated in the distal half, the abdomen being 

 therefore stalked ; the segments bear on the sides below some 

 rather long and strong bristles. Ovi[)ositor exceedingly 

 strong and thick, clothed with long and dense hairs ; it is 

 longer than the abdomen, and bears at base below a very 

 large prominent tubercle, directed forwards. 



Legs rather short and strong, with somewhat thickened 

 femora ; the femora are clothed with long hairs, those of the 

 front pair showing below a complete row of very long but 

 thin bristles ; coxae with long bristles. 



Wings rather small, proportionally short and narrow ; 

 second and third longitudinal veins straight and parallel, the
