10G SY.1U41IDJE. 



112. Syritta aculeipes, Schlner (1868). 



A single male specimen from Nairobi, 5. vi. 1911, appaars to 

 belong to this species, which, with the exception of the hind 

 femora, agrees in all respects with the foregoing. 



113. Syritta bulbus, Walker (1849). 



I believe I have this species before me in the shape of a female 

 from Obuasi, Ashanti, West Africa (Dr. W. J/". G-rahatn), which 

 is readily distinguishable owing to the yellow colour of the thoracic 

 pollen, of the hind femora, and of the abdominal spots. The 

 abdomen, which is wanting in Walker's specimen, is velvety black, 

 shining only on the last segment ; the first segment has a small 

 yellow spot on the sides ; the second and third have broader lateral 

 yellow spots ; the fourth has a yellow spot on the fore corner and 

 a yellow hind border; the hind femora have a very strong basil 

 spine. This specimen agrees very well with the description of 

 6}. bulbuliis, Speiser, 1913. 



I also refer to this species a male from Durban, Natal, 8. ix. 

 1903 (F. Muir), which shows the same coloration of the hin 1 

 femora, and has also a strong basal spine on the latter ; its color- 

 ation, however, is like that of pipiens, and the thoracic tomuntum 

 has the usual colour and disposition. 



111. Syritta fasciata, Wiedemann (1830). 



I am of opinion that the present species is the Ethiopian repre- 

 sentative of xS'. pipiens, L., from which it differs in its sm iller size, 

 paler antennae and face, more extended yellow markings on the 

 abdomen, the second yellow band (i. e. that on the third segment) 

 bjing mostly uninterrupted in the middle in the male and being 

 very broad in the female. The hind femora are black, varying 

 more or less to a reddish brown ; thay are finely toothed beneath 

 and bear long white hairs, which, as in pipiens, appear to be 

 deciduous. Hind trochanters smooth, not so beset with minute 

 spines as in pipiens ; coloration of abdomen and legs apparently 

 variable as in pipiens. 



S. abyssinica, Rondani, from Keren, Abyssinia, of which I have 

 topotypes before me, is only a smaller variety with black hind 

 femora. 



Two males from Durban, Natal (F. Muir\ and one from Sierra 

 Lxme (J. Fox croft). 



115. Syritta stigmatica, Loew (1858). 



I refer with some doubt to this species some specimens which 

 seem to be only a variety of the preceding. They are usually of 

 greater size, the yellow markings on the third abdominal segment 

 of the female arc greatly reduced, the wings are more or less infus-
