segment ; pubescence and bristles black ; venter yellowish ; ovipositor black. Legs 

 and coxae entirely pale yellowish, with whitish pubescence and yellow bristles ; only 

 the apical spur of the middle tibiae and the tip of the claws are black. Wings wholly 

 infuscated, more intensively on the elongated stigma and near the end of fore border ; 

 there is a small rectangular hyaline spot on the costa, just behind the upper end of the 

 stigma, as long as one third or one half of the marginal cell ; another small hyaline 

 rounded indentation at the middle of the 2nd posterior cell on the wing border ; the 

 3rd posterior cell at hind border and almost the whole of the axillary cell are greyish 

 hyaline. In the middle of the wing there is always present a small, rounded, hyaline 

 dot at the middle of the base of the 1st posterior cell, a little before the hind cross- 

 vein ; besides there are more or less distinct traces of two other dots, one in the 

 discoidal cell below the small cross-vein, and one in the 1st basal cell ; these three 

 dots are placed symmetrically around the small cross- vein, thus forming nearly an 

 equilateral triangle. The veins are blackish, with yellowish base. 



Type ^ and type Q. (British Museum) and some additional specimens from 

 Nyasaland, Mt. Mlanje, 22-26th November 1912, collected by S. A. Neave y 'm whose 

 honour the species is named. 



This species is certainly distinct from the undescribed type-species of the genus, 

 P. preussi, Hendel, 1914, from Camerun. 



2. Ptiloniola tripunctulata, Karsch, Ent. Nachr., xiii, 1887, p. 5, fig. 4. 



Described from Pungo Andongo, W. Africa, as a Hemilea. The figure of the wing 

 pattern shows a great resemblance to that of the above-described neavei, but the 

 three hyaline discal spots are more developed, and that of the discoidal cell, instead 

 of being placed near the small cross-vein, is very near the hind one, and therefore 

 they are not disposed symmetrically as in neavei. The thorax is described as having 

 two (not one) blackish stripes on each side. 



Perhaps it will be found that the present species is the same as preussi, if the hind 

 femora prove to be provided with bristles. 



Note. — I do not know what .is the genus Coelopacidia, with the type-species 

 C. madagascariefisis, Enderlein (Zool. Zahrb., xxxi, 1911, p. 442), from Madagascar, 

 and I am unable to establish its systematic position. The author places it near 

 Acidia, but in Prof. Hendel's table it comes near Platyparea. 



XIV. Ehacochlaena, Loew, 1862. 



This genus, which was founded on a very rare European species, is clearly 

 differentiated from all the others here recorded on account of the complete want of 

 the prst. ; a character which it shares only with the genus Staurella and which seems 

 to be only rarely present in Ethiopian Trypaneids. As I have before me the single 

 Ethiopian species of the present genus, which was described by Loew in a few words 

 only, I will give here a complete description of it : — 



1. Rhacochlaena fasciolata, Loew, Wien. Ent. Monats., vii, 1863, p. 16 (fig. 2). 



The two broad shining black spots of occiput extend obliquely from the insertion 

 of the neck to the upper edge of the eyes ; they are narrowly margined with yellow. 

 The frons is dull, shining only near the vertex, with a black ocellar spot and a dark
