74 SYRPIIID^. 



70. Phytomia fucoides, sp. n. 



$ . Length of the body 15 mm. 



This species unites the characters of the bunata-groMip with 

 those of the zonata-grou.p, agreeing in shape with natalensis, but 

 not being yellow-banded ; it is distinguished by its black abdomen 

 and by the wings being pubescent on the basal half. 



Head black, grey pollinose, moderately shining; frons broad, 

 gently rounded, clothed with rather long and closely-set yellowish 

 hairs, which are dark towards the middle; occipital border almost 

 bare, white below ; supra-antennal area rather small, dark reddish, 

 more deeply punctate than wrinkled; antennae short, blackish 

 brown, the third joint rounded, with a reddish arista, which is 

 plumose basally ; face broad, with short yellowish hairs, the tubercle 

 rather prominent but rounded, the lateral keels rather distinct ; 

 peristoma broad, shining black on the middle, yellowish pilose 

 beneath ; opening of buccal cavity small ; proboscis black ; eyes 

 small, purplish black, with (?) four bands. Thorax black, dark 

 pollinose, dark reddish on the humeri, clothed on the dorsum with 

 dense yellowish-red hairs, and on the pleurae with paler hairs, though 

 those on the mesopleurse are black. Scutellum dull black, dark 

 red towards the hind border, margined, and densely clothed with 

 erect cinnamon -rufous hair ; squamulae black and black-fringed ; 

 halteres brownish ; subalar callosity dark brownish. Abdomen 

 dull black, somewhat shining towards the distal extremity ; the 

 hair is short and dense, longer towards the apex, coloured like that 

 on the thorax, but darker on the middle and hind border of each 

 segment. Legs black and clothed with similarly coloured hair, all 

 the tibiae whitish towards the base, and there pale pilose ; tarsi 

 dark red, those on the first pair short and broad. Wings hyaline, 

 with typical venation, the basal half as far as the base of the 

 discal cell appearing infuscated on account of its dense pubescence. 



Type $ , a single specimen from the Uganda Protectorate, Daro 

 or Burro Forest, Toro, 4,000-4,500 ft,, 25-29. ix. 1911 (S. A. 

 Neave). 



There is in the collection a damaged female specimen, without a 

 head, from Madagascar, Ambohimitombo, 26. i. 1895 (Dr. Forst/fk 

 Major), very like the present species, but distinguished by the 

 second abdominal segment being yellowish on the sides, and by the 

 legs being quite black, except the tarsi which are bright orange. 



71. Phytomia (Eristalis) fronto, Loew (1858). 



A species resembling E. tenax, with hind tarsi of ordinary 

 length, very broad black face, and frons densely clothed with long 

 hairs. 



Described from Caffraria by Loew, and not recorded again till now. 

 Typical specimens have the second abdominal segment yellow with 

 a broad black hind border and a short black transverse band on the 

 fore border; the third and fourth segments are also yellow on the 

 fore border.
