NOTES ON THE ETHIOPIAN FRUIT-FLIES — II. 29 



3. Spathulina acrosticta, sp. nov. 



A species very distinct from any other on account of the isolated black spot at the 

 end of the third longitudinal vein. 



$. Length of the body, 3 5 mm. ; of the ovipositor, 0"6 mm. ; of the wing, 3 '5 mm. 

 Head rather depressed, entirely pale yellowish, with the occiput a little infuscated 

 in the middle and the frons with a yellow middle stripe ; all the bristles are black, 

 but the pvt., the vt. and those of the occipital row are whitish ; there are 2 lower or. 

 Antennae shorter than the face, yellow, with the third joint rounded at end ; arista 

 bare. Palpi and proboscis yellow. Thorax and scutellum black, clothed with a dense 

 grey dust, opaque ; the bristles are black, only the pt. being whitish ; mesophragma 

 black, faintly dusted. Scutellum with only the basal pair of bristles. Abdomen 

 entirely shining black, with black bristles ; ovipositor shining black, obtuse, 

 depressed. Legs entirely yellow ; hind tibiae without distinct row of bristles. 

 Wings elongate, broadly hyaline at base, with the following hyaline spots : 1 at 

 end of the second costal cell, limited interiorly by a narrow black streak ; 3 of about 

 equal size in the marginal cell ; 2 in the submarginal cell, one below the middle of 

 the three above named, and the other at the end ; 2 of greater size and of rounded 

 shape before and behind the small cross-vein ; 1 at end of the first posterior cell, 

 forming the broad hyaline apical patch in which is the isolated black spot. 



Type $, a single partly damaged specimen from Durban, Umbilo, 26. iv. 1914 

 (L. Bevis). 



4. Spathulina aldabrensiS, Lamb, Trans. Linn. Soc. London, Zool., xvi, 1914, 



p. 319, fig. 12 & pi. xix, fig. 9. 

 Described as a Tephritis from the Island of Aldabra. The scutellum has a long 

 basal and a very small apical pair of bristles. 



5. Spathulina margaritifera, Bezzi, Bull. Soc. Ent. Ital., xxxix (1907), 1908, p. 160. 

 Closely allied to semiatra, but easily distinguished by the more numerous hyaline 



spots of the wings. 



Described from Erythraea, Adi Ugri. 



XXIX. Euaeesta, Loew (1873). 



This artificial genus is taken here in a somewhat wider sense than that attributed 

 to it by Loew, and more corresponding to that used by Hendel, but without the 

 restriction of the radiating marginal wing pattern. Thus I provisionally place 

 here the species which differ from Euribia in having a more extensive black pattern 

 on the wings, with a few hyaline spots. They are distinguished from the preceding 

 genus in having a short proboscis and usually 4 scutellar bristles of equal size. But 

 this latter character must be used with caution, because in some species (for 

 example, in megacephala, Loew) the apical bristles are wanting. 



For the species in which the black pattern of the wing is not radiating at apex, 

 the new subgenus Pliomelaena is erected here. The African species can be 

 distinguished as follows : — 



1(2). Black wing pattern radiating at end and at the hind border (Euaresta s. str.) ; 

 stigma entirely black ; the greater part of the third posterior cell and the 

 whole axillary cell hyaline. . . . . . . . . . planifrons, Loew.
