NOTES ON THE ETHIOPIAN FRUIT-FLIES — I. 243 



reddish yellow, with pale pubescence ; ovipositor reddish, shining, with yellowish 

 pubescence. Leg entirely pale yellowish, immaculate, with yellowish pubescence 

 and bristles ; the bristles of the front femora very strong in the female. 

 Wings shining, with yellow veins ; the base broadly yellow to the small cross- vein ; 

 from it there runs a marginal stripe, which does not extend below beyond the 3rd 

 longitudinal vein, being only slightly produced beyond that vein at its apex ; this 

 stripe is yellowish in colour, but has some dark spots along the costa (two in the costal 

 and two in the marginal cell) and is besides infuscated at the apex. The second 

 longitudinal stripe, or yellowish ray, runs along the upper vein of the discoidal cell, 

 ending at its apex and there being bent below to form a dark band over the hind 

 cross-vein. A small, oblique, fuscous band crosses the middle of the last portion of 

 the 4th vein, extending from the hind border of the wing to the 3rd vein, which meets 

 the costal stripe. The hind border of the wing is broadly but faintly yellowish- 

 fuscous on the 3rd posterior and axillary cells. The stigma is yellow like the costal 

 stripe, but is broadly and faintly infuscated towards the middle. 



I assume the above-described species to be identical with that named, but not 

 described, by Prof. Hendel from E. Africa. There are in the collection some 

 specimens from British East Africa, Masai Reserve, viz. a <$ from Ngare Narok, 

 31st December 1913, about 6,000 ft. (Capt. A. 0. Luckman), and a couple, 2nd April 

 1913 (T. J. Anderson). I have in my collection a male taken at Kikuyu by Doherty, 

 and given me many years ago by the late Dr. Magretti, the well-known dipterologist. 



Trypeta jucunda, Loew (Berl. Ent. Zeits., v, 1863, p. 258, pi. ii, fig. 1), from 

 Caffraria, is perhaps allied to this species, but apparently not congeneric with it, on 

 account of its bare arista, short ovipositor and very differently placed small cross- vein ; 

 it is besides much darker in body coloration, and the wing pattern is of a very 

 different type. 



X. Themarictera, Hendel, 1914. 



This genus also was recently erected by Prof. Hendel* on the undescribed type- 

 species Th. rufipennis from S. Nigeria. I will give here the essential characters of the 

 genus from a species which I assume to be the Trypeta flaveolaia of Fabricius and 

 Wiedemann, with which probably the species of Prof. Hendel is identical. 



Head very broad, twice as broad as high, and considerably broader than the 

 thorax. Eyes rather rounded, being only a little higher than broad. Frons very 

 broad, not prominent at base, but rather prominent at its apex. Antennae inserted 

 towards the middle of eyes, only a little shorter than the face ; 3rd joint rounded at 

 end ; arista broadly plumose. Face concave, with a flat, triangular middle keel, 

 rather prominent at mouth-border ; antennal grooves narrow and deep. Cheeks 

 moderately broad, jowls very broad : mouth-opening broad. Palpi less dilated 

 at end, bristly ; proboscis short. Cephalic chaetotaxy complete, with 2 i. or., the 

 2nd pair of which is placed much nearer the middle line than the first ; but all the 

 other bristles are broken off in the specimen examined. Thorax elongate, with 

 complete chaetotaxy, but the st. wanting (according to Hendel) ; 1 mpl. ; dc. placed 

 much behind, about in the line of the first p. sa. Scutellum proportionally small, 

 flat above, triangular, with two pairs of strong bristles and between these a 3rd pair
