NOTES ON THE LONCHAEIDAE (DIPT.) ' 201 



15(14). Antennae with the interior part of 2nd and 3rd joint yellowish ; wings quite 

 hyaline . . . . . . . . . . . . impressifronSj «p. n. 



16(5) . Arista plumose or at least long-haired ; two strong sternopleural macrochaetae 

 present ; antennae always extending to the mouth-border, or even be^ow, 

 with the third joint many times longer than the basal joints together; iowls 

 Unear ; tarsi entirely black ; first posterior cell not narrowed at end (subgen. 

 Carpolonchaea, nov ). All the Ethiopian species here distinguished have 

 white and pale hairy squamulae, and hyaline or pale yellowish wings. 



17(24). Plumosity of the arista of medium length, being not or only a little broader 

 than the breadth of the third antennal joint ; the plumules are moreover 

 thin, straight and close together. 



18(19). Last abdominal segment of the male longer than the two preceding ones 

 together, deeply incised at end and there with the two points clothed 

 with dense and long, bristly hairs . . . . . . exci a, Kert. 



19(18). Last abdominal segment of the male not so formed, never specially ciliated. 



20(21). Abdomen at end with the two last ventral plates inflated and prominent ; 

 smallish species with bare scutellum . . . . gibbosa, de Meij. 



21(20). Last ventral plates not so formed, never prominent ; scutellum more 

 hairy. 



22(23). Bluish species of smaller size (not over 4 mm. ) ; plumosity of the arista 

 broader than the breadth of third antennal joint ; wings quite hyaline 



laevis, sp. n. 



23(22). Black species of greater size, plumosity of the arista as broad as the third 

 antennal^joint ; wings slightly but distinctly yellowish 



ophyroides, sp. n. 



24(17). Plumosity of the arista very long, being twice as broad as the breadth of 

 the third antennal joint ; the plumules moreover less thin, undulated 

 and scattered . . . . . . . . plumosissima, Bezzi. 



1. Lonchaea (Dasyops) phaeoiepis, sp. nov. 



Closely allied to mocJiii, Bezzi, from Erythraea, but smaller and at once 

 distinguished by the characters given in the table. 



cJ $. Length of the body, 3-3 '2 mm. ; of the wing, 2 '9-3 mm. 



Head and its appendages as described for mochii, with the following differences : 

 the frons lacks the greenish reflexions ; the cheeks in the upper part and the sides of 

 frons in the anterior part with rather developed transverse furrows, being thus 

 strongly rugose ; arista yellowish at base. Thorax and scutellum without distinct 

 aeneous reflexions, and with the same chaetotaxy. Squamulae blackish, and with 

 a blackish fringed border ; halteres black, with paler stalk. Abdomen as in mochii, 

 but the ovipositor is distinctly shorter and broader. Legs of all the pairs with the 

 tarsi entirely yellow, the last joint only being black. Wings proportionally shorter 

 and broader, with the base deep blackish to the basal cross- veins ; the first 

 posterior cell is not distinctly narrowed at end ; the sixth longitudinal vein is shorter. 



Type cJ and type 9, and a single couple of specimens (British Museum) from 

 Durban, Umbilo, 16. xi. 1913 and 23.iii.1914 {L. Bevis). In the Cape Museum 

 there is a specimen from Natal.
