﻿134 ERNEST E. AUSTEN — NEW AFRICAN 



segment, the broad grey stripe between the admedian dark stripe and the dark 

 lateral margin on each side consisting of a continuous series of oblong blotches, 

 one on each segment, the inner margin of each blotch being roughly parallel to 

 the lateral margin of the segment, while the outer margin of each blotch runs 

 obliquely backwards and outwards ; hind margins of dorsal scutes of second and 

 following abdominal segments often narrowly grey ; dark stripes on dorsum 

 clothed with minute, appressed, blackish or black hairs, grey stripes clothed with 

 similar yellowish hairs ; lateral borders of dorsal scutes of all segments except 

 last two light smoke-grey pollinose (invisible from above in case of dried speci- 

 mens) ; venter light smoke-grey pollinose, clothed, except in case of last segment, 

 with minute, appressed, yellowish hairs, ventral scutes of first four segments 

 more or less fawn-coloured, hind borders of second to sixth segments inclusive 

 cream-buff. Wings faintly tinged with drab ; veins mummy-brown ; stigma 

 mummy-brown, elongate, and often conspicuous. Squamae isabella-coloured, 

 borders cream-buff or fawn-coloured. Halteres (in dried specimens often appear- 

 ing pinkish or fawn-coloured) : knobs yellowish cream-coloured, stalks ochraceous- 

 buff. Legs : femora lighter or darker grey, clothed with whitish hair, their 

 distal extremities or extreme tips buff or ochraceous-buff' ; tibiae buff or 

 ochraceous-buff, tips of front pair dark brown ; front tarsi clove-brown or dark 

 brown, not expanded, middle and hind tarsi ochraceous or ochraceous-buff, tips 

 of joints dark brown, last joint of hind tarsi often entirely dark brown. 



Nyasaland Protectorate : type and four other specimens (para-types) 

 from Fort Johnston, South Nyasa, 26. ii. 191(3, " taken in goat-kraal " 

 {Dr. A. II. Barclay) ; four specimens from the Shire River, alt. 2,000 ft., 

 1, 3, 25. iii. 1910, and two other specimens from Fort Johnston, 24. iii. 1910 

 {Dr. A. H. Barclay) ; one specimen from Kambiri, Central Angoniland, near 

 Lake Nyasa, 28. i. 1910, and two specimens from the vicinity of the Livelezi 

 River, South Nyasa, 3. ii. 1910 {Dr. J. B. Davey) ; two specimens from Zomba 

 District, 1909 {Dr. S. K. Norris) : — all except the last two presented to the 

 British Museum (Natural History) by the Entomological Research Committee. 



In addition to the foregoing, the following in the possession of the Committee 

 have also been examined ; seven specimens taken by Dr. Barclay between 

 26. ii. and 24 iii. 1910, at the localities already mentioned ; two specimens 

 taken by Dr. J. B. Davey, 2. ii. 1910, at the locality mentioned above ; one 

 specimen from Fort Johnston, February, 1910 {S. A. Neave) ; and one specimen 

 from Liwonde, 20. i. 1911 {Dr. J. E. S. Old). 



The species described above, which has been named in honour of one of its 

 discoverers and is apparently common in South Nyasa in February and March, 

 is allied to Tabanus pallid if acics, Surcouf, which is at present known only from 

 the East Africa Protectorate. Tabanus barclayi, which resembles T. pallidifacics 

 in the width of its front and the shape of its frontal callus, may however be 

 distinguished from the species mentioned by the narrower shape of its body, by 

 the front being if anything wider below than above (instead of the reverse), 

 and by its abdominal markings, — the greyish longitudinal stripe on the dorsum 

 between the median stripe and each lateral margin not being broken up into a 

 series of oblique spots.
