(S. A. Neave*) ; a female from Chirincla Forest, Melsetter District, 

 S. Rhodesia, x. 1905 ( G. A. K. Mars Jin II) ; two males and a female 

 from the same locality, 3,800 ft,, 3-20. iv. 1910, " very common in 

 house" (C. F. M. Swyuncrton). 



48. Bhingia cserulescens, Loew (1858). 



A pretty violaceous or aeneous species, with reddish snout and 

 -wholly metallic, not banded, abdomen, which is more or less broadly 

 yellow towards the base. 



The present species is of the same size as the preceding one, but 

 very different in coloration. The yellow on the base of the 

 abdomen is- very .variable ; some specimens have only the first 

 segment and a median spot on the second segment yellow ; some 

 others have the second segment yellow, except on the sides, and 

 the third with a more or less broad yellow median spot. B.isal 

 black streak on the front tarsi very distinct. 



This species, like the preceding one, in whose company it is 

 often found, seems to be very common. A female from Marsabit, 

 British East Africa, 23. ix. 1911 (11. J. Stordi/) ; Chirinda Forest, 

 S. Rhodesia ( G-. A. K. Marshall and C. P. M. Swynnerton) ; 

 Zomba, Nyasaland (Dr. If. S. Stannug) ; Lualaba River, Belgian 

 Congo, 1910 (Dr. A. Yale Massey) ; a male from Western 

 Ankole, Uganda Protectorate, 4,500-5,000 ft., 12-14. x. 1911 (S. 

 A. Neave). 



Var. fuscipes, var. n. 



c? ? Length of body 11 mm. 



Distinguished from the typical form by its slightly greater si/e, 

 and by having all the femora more or less dark brown or black, with 

 only the apex yellow ; sometimes the hind tibiae also are blackish 

 in the middle and all the tarsi darkened towards the end. 



Type d and iype $ from Chirinda Forest, S. Rhodesia, 3,800 ft., 

 3. iv. 1910 (C. F. M. Swynnertoti) ; a male from N.-E. Rhodesia, 

 near R. Chire, 17. ii. 1909 (Dr. J. B. Davcy); a female from 

 N. Nyasa, Mt, Waller, l.ix. 1909 (Dr. J. B. Davey). 



49. Rhingia pycnosoma, sp. n. 



c? . Length of body 10'5 mm. 



A wholly shining caeruleous species, resembling a Pycnosoma, 

 very distinct from any other on account of its caeruleous frontal 

 triangle, face, and snout. 



This species seems to be closely allied to cyanoprora, Speiser, 

 and pulcherrima, Bezzi, but differs from both in the coloration 

 of the legs, and from the former in the thorax being all cseruleous 

 without yellow markings. R. ccerulea, recently described by me, 

 is perhaps the female of the present species, but has a yellow face 

 and snout,
