TOMOMYZA, Wied. 



TOMOMYZA PICTIPENNIS, Bezzi, 11. Sp. 



A very distinct species, resembling a small specimen of Henica, but 

 belonging to the gen. Tomomyza in its true sense, as indicated in my 

 key of the genera (' Ann. S. Afr. Mus.,' xviii, p. 5). The Mediterranean 

 species, attributed wrongly to the present genus, must be removed to 

 Stomylomyia, Big., and belongs to the Lomatiinae. 



Several specimens f rom Willowmore (Cape), December and January, 

 Dr. H. Brauus ; the species will be more fully described in my paper 

 on the Bombyliidae of the Hungarian Museum. 



CYLLENIINAE. 



PANTOSTOMUS, u. gen. 

 PANTOSTOMUS GIBBIVENTRIS, Bezzi, n. sp. 



A species very distinct 011 account of its gibbose abdominal seg- 

 ments. Some specimens from Willowmore (Cape), December and 

 January, Dr. H. Brauus. The new gen. Pantostomus of the CyUetiiinae 

 agrees with Toitwmyza in the absence of ocelli, in the hairy metapleura 

 and in other characters ; but it is at once distinguished by the 

 face being practically wanting, the mouth-opening extending to the 

 base of the antennae. Both the new genus and the new species will be 

 fully described in my forthcoming paper on the Hungarian Museum 

 material. 



EXOPROSOPINAE. 



THYRIDANTHRAX, 0. Sack. 

 THYRIDANTHKAX LUTULENTUS, n. sp. 



Near T. leucoproctus, but distinguished by the greater size, the 

 dense tufts of yellow hairs on the sides of thorax and by the more 

 yellowish base of the wings. 



Type ? , a single specimen from S.W. Protectorate, Otjiverongo, 

 April, 1921 (J. S. Brown). 



9- Length of body 11 mm.; of wing 10 mm. Head] entirely 

 black ; occiput with white scales at eye border, chiefly near the 

 indentation. Frons clothed with short black hairs, more densely 

 on the anterior half. Face bluntly convex, not much, yet distinctly 

 prominent, with black hairs at mouth border and with yellowish ones 

 at sides. Antennae quite black, with the third joint elongate conical.
