South African Higher Myodarii (Diptera Galyptratae). 509 



nearly orange, wider than the orbits ; width of vertex that of 

 the eye. Antennae yellow, reaching only the lower J of the cavity ; 

 3rd joint hardly twice the length of the 2nd ; autennal chaeta black ; 

 strongly thickened at the base; palpi yellow. The inferior level of 

 the eyes is plainly below the anterior buccal border. brownish ; 



in the $ , the joints of the anterior tarsi bear a small internal seta. 



Length 7-8 mm.

The facies of the African representatives of this species is somewhat 

 variable. The red colour of the sides disappears almost totally on 

 the abdomen of the $ $ ; the orbits are golden yellow, as is also the 

 upper part of the genae ; the autenual chaeta is so elongate as to pro 

 ject occasionally beyond the antennae ; the. latter is often short, and 

 the great vibrissae are then a little more raised. These remarks apply 

 also to examples from the coast of Malabar, although in the (J c? 

 abdominal sides remain more or less broadly reddish. These variations 

 do not justify making a new species, but one must see in the Afncar 

 and Asiatic forms a variety which I call " otecurior" the more 

 that on the side of the thorax the tergum becomes obscure at the back 

 of the suture, and the scutellum wholly black, so that the dark hues 

 so well denned in the palaearctic S. fasciata are only visible in 1 

 anterior part of the tergum. 



Two other examples, a $ from South Africa, and 1 ? from 

 Belgium Congo represent another variety, i.e. angustifrons. Here the 

 frons is narrower ; the orbits, which are white like the face, are wider 

 than the narrow frontal band, or at most equal in width, 

 antennae are of normal length.

HOPLOCEPHALELLA GRISEA, n. Sp. 



The $ is at once recognised from H. signataTill.: (1) by its smaller 

 size and more slender build ; (2) by the different coloration of the 

 thorax and scutellum, the latter being black and the dark grey thorax 

 bearing 5 black bands ; (3) by the ashy white head, with the frons 

 hardly equal to f the distance from eye to vertex, and not mucl 

 broadening in front, so that on the whole it is narrower ; the frontal
