BACCHA. 49 



subsequently, the late 31 r. Yen-all recorded the Oriental sapphirina 

 from Aden, and Dr. Speiser has even reported it from Erythraea 

 therefore I now think that we have only one species, which is widely 

 distributed in the Oriental and Ethiopian Kegions. like Paragus 

 serratus. 



Eves with a median brown band only. 



There are in the collection six males and two females from Zun- 

 geru, Northern Nigeria, 29. iii. 1911 (Dr. J. W. S. Macfie} ; also a 

 male from Durban, 6. vi. 1903 ( F. Muir). Another male from 

 Salisbury, S. lihodesia (G. A. K. Marshall}, shows below the 

 stigma an ill-defined dark yellowish spot, extending over the small 

 cross-vein to the fourth vein, like that Avhich I described in 1908 ; 

 Dr. Kertesz has figured it as characteristic of the male wing in 

 Ann. Mus. Nation. Hungar. xi. p. 280, fig. 7 a (1913), but in 

 Ethiopian specimens it is often entirely wanting. 



43. Baccha praeusta, sp. n. 



. Length of body 8 to 10 mm., of wing 5 to 7 mm. 



A black species, very like the preceding, but with darker antennse 

 and greyish hyaline wings, which have no apical spot, but are only 

 narrowly infuscate near the tip. 



Head" shining black, with bluish reflexions ; frons pale-haired, 

 with a transverse whitish band on the depression ; antermal tubercle 

 rounded and large, rather prominent ; no distinct ocellar tubercle ; 

 facial tubercle small, but narrow and cariniform ; peristoma linear ; 

 face with whitish dusting on the sides ; occipital fringe of typical 

 shape, white ; eyes apparently with the middle band only ; antenna} 

 short, dark yellow, almost brownish. Thorax and scutel'lum shining 

 black, without any yellow marking, clothed with sparse whitish 

 hairs, which are longer and whiter on the mesopleurae. Halteres 

 and squamulse white, the latter with short white fringe. Abdomen 

 with a long stalk and the spatulate portion not very broad ; it 

 is black, with bluish bands at the base of the third and fouith 

 segments, that on the third broader than the other; stalk with 

 long erect white hairs on the sides, the hairs elsewhere rather 

 long, but darker. Venter black. Legs yellow, with black coxae ; 

 the four front femora broadly black at the base, but the extreme 

 base yellowish ; hind femora black, narrowly yellow at both ends ; 

 tibiae' black, broadly yellow towards the base ; tarsi black, with 

 yellowish first joint. Wings short and rather broad, rounded out- 

 wards, uniformly pubescent and therefore greyish hyaline ; the 

 stigma blackish; the apical infuscation small, but very distinct; 

 third and seventh veins almost straight ; alula and axillary lobe 

 broad ; veins black and thick. 



Type $ and four additional specimens from Obuasi, Ashanti, 

 viii.-xii. 1907 (Dr. W. 31. Graham). 



r Male. A specimen from Durban, 1903 ( F. Jlfuir), seems to 

 be the male of the present species. Head, antennas, and thorax as 

 in the female. Abdomen with a long stalk, with the spatulate
