NOTES ON THE ETHIOPIAN FRUIT-FLIES — II 27 



on the mesopleura and a broader one on the sternopleura ; scutellura reddish, 

 broadly black at base above, and with 4 black spots at the base of the 4 macrochaetae ; 

 mesophragma black. All the bristles are pale yellowish ; dc placed much before 

 the line of the a. sa. ; 1 mpl. ; scp. indistinct ; the pubescence of the back is yellowish ; 

 4 scutellar bristles, those of the middle pair being shorter and crossed at the tips. 

 Halteres pale yellowish. Abdomen broad, reddish brown, with 4 rows of broad black 

 spots, the 2 middle rows being more marked ; the pubescence is pale yellowish, but 

 is black on the black spots ; bristles black ; ovipositor flat, reddish. Legs entirely 

 reddish, but the femora with two black spots in the middle forming a more or less 

 complete ring, which is more developed on the hind pair, in which there is also a 

 black spot at base beneath ; front femora with 4-5 yellowish bristles beneath ; 

 hind tibiae with a well-developed row of black bristles. Wings broad and rounded, 

 with obtuse end and with rather broad axillary lobe ; costal bristle long and double ; 

 small cross-vein placed beyond the middle of the discoidal cell ; lower angle of the 

 anal cell shortly produced. The wings are entirely and intensely black, even at the 

 extreme base and on the axillary lobe ; they are adorned with very numerous whitish 

 dots, which are more abundant in the marginal and submarginal cells, and scarcer 

 in the hind half of the wing ; on the axillary lobe they are fewer but broader ; 

 besides in the middle of the wing there are some more intensely black spots on the 

 3rd and 4th longitudinal veins, four of which are better defined and form a square, 

 being symmetrically placed about the small cross-vein. Around the whole border of 

 the wings there is a series of slightly larger and more whitish, elongate spots, 1 in the 

 first costal cell, 2 in the second costal, 2 in the stigma (the first being the smaller), 

 3 in the marginal, 2 in the submarginal (the second of which is smaller), 1 at end of 

 the first posterior cell occupying the space between the ends of 3rd and 4th 

 longitudinal veins, 4 in the second posterior cell, the last of which is much smaller, 

 3 in the third posterior cell being all very small, and 4 or 5 in the axillary cell, which 

 are larger and more elongate. Third longitudinal vein bare. 



Type $, a single specimen in the writer's collection from Erythraea, Ghinda, 

 March 1916 (Dr. A. Mochi). 



5. Eutretosoma polygramma, Walker (1861). 



The peculiar wing pattern and the very different coloration of the legs are 

 distinctive features. 



Described from Natal, and not recorded subsequently. 



XXVII. Elaphromyia, Bigot (1859). 



Of this very peculiar genus, which I described for the Oriental fauna under the 

 name of Parallelojtera (1913), there are in Africa the two following species : — 



1. Elaphromyia adatha, Walker (1849). 



Described from Congo and not recorded subsequently ; it is closely allied to the 

 following species, from which it seems to be distinct in having the wing base broadly 

 hyaline.* 



* [In E. adatha it is not the basal half of the wing that is hyaline, but the basal half 

 of the posterior border only ; E. uhda is undoubtedly synonymous with tbis species. — ■
