1LELOPIIILUS. 97 



Type c? from Chintechi, Nyasaland (Dr. H. S. Stannus), and 

 an additional specimen from North Nyasa, Songwe lliver, 17. ix. 

 1909 (Dr. J. IB. Da vet/)'; type $ and another specimen from N. 

 of Mount Kenia, near Crater Lake, 5,700 ft., 15. ii. 1911 (T. J. 

 Anderson). 



101. H. (Mesembrius) africanus, Verrall (1898). 



A single female specimen from British East Africa, Makindu, 

 3,300 ft., 5-7. iv. 1911 (S. A. Neave), which agrees very well with 

 the description of this species from Aden, but also with that of 

 tenegalensis, Macq. 



102. H. (Mesembrius) ingratus, Loeio (1858). 



A very distinct species, with entirely black legs. Front tarsi of 

 the male short and broad, yellow ; the first joint bears on the out- 

 side a tuft of black hairs, which are like those of the tibiae ; the 

 last joint has two very distinct black rounded spots. Hind tibiae 

 with a prominent tubercle on the last third ; hind tarsi black, the 

 first joint rather swollen. 



The present species shows a great many characters of the genus 

 Prionot&myia, Bigot, which is therefore probably synonymous 

 with Mesembriut *. Two males from N.E. side of Lake Albert 

 Edward, Uganda, 1906 (Dr. A. D. P. Hodges) ; a couple from 

 Durban, 26. x. 1902 (F. Bluir) ; some additional specimens of both 

 sexes from Uganda, various localities (Dr. R. van Someren). 



103. H. (Mesembrius) cyanipennis, sp. n. 



c? . Length of the body 10-12 mm. 



A very distinct black species, with the abdomen mainly reddish and 

 with infuscated wings, which have very strong bluish reflexions. 



Head black, the frons with black, the occiput with yellowish, 

 and the face with white, hair ; face with a faint whitish pollen, 

 the median black stripe being therefore indistinct; antennae 

 entirely black, the third joint rounded ; face with a distinct but 

 not very prominent tubercle ; eyes bare, unicolorous, in the malo 

 approximated but not touching; frons of female shining blaek, 

 with an indistinct transverse greyish band in the middle. Thorax 

 and scutellum entirely black, slightly shining, but the scutellum 

 reddish along the hind border ; the hair is short and grey, longer 

 and paler on the pleurae ; the thorax shows no distinct stripes on 

 the back, but two parallel rather distinct longitudinal furrows. 

 Squamulae pure white and with a white fringe ; haltares yellowish. 

 Abdomen of male more red than yellow ; lirst segment black ; 



* Since this was written Dr. Speiser has shown that the synonymy here 

 suggested is correct.
