Bombyliidae (Diptera) from Central Africa. 633 
6 (8). Propleurae and metapleurae with golden-reddish hairs; a 
pellucid spot on the small cross-vein. 
7 (8). Third joint of the antennae elongated, as long as or longer 
than the style , : ‘ ‘ tollini, Loew. 
8 (7). Third joint short, much shorter than the style 
perplexus, sp. n. 
45. Lntorrhynchus repletus, sp. nov. (Plate L, fig. 12.) 
9. Length of the body 6 mm., of the wing 8 mm. A small 
species, very distinct from all the others of this second group, owing 
to the black end of the marginal cell. 
Head, dark yellowish, blackened on the frons and on the occiput, 
clothed with black hairs and with sparse pale pubescence, antennae 
short, the two basal joints reddish, the third blackened, of a short 
conical shape, much shorter than the style. Proboscis 4 mm. long ; 
palpi darkened. Thorax black, with pale pubescence; the hairs 
are long, those on the collar yellow, on the pleurae partly black 
and partly golden; the bristles are black and very long. MHalteres 
black, with greyish knob, Scutellum dark red, with very long 
marginal black bristles. Squamulae blackish. Abdomen black, red 
on the sides of second, third and fourth segments ; first segment with 
white hairs on the sides ; the silvery spots on the third segment are 
well developed ; the hairs are black, those on the sides are disposed 
in the shape of a fringe, and are all black. Spines of the female 
genitalia yellow ; underside of the abdomen dark blackish, yellowish 
towards the middle. Legs dark reddish, the tibiae paler ; bristles 
black; tooth of the hind claws very small, indistinct. Pattern ofthe 
wing black, as in the following species; but the black colour fills the 
marginal cell and extends over half of the apical submarginal cell ; 
small cross-vein without pellucid spot ; hyaline spot of the second 
basal cell large ; the upper internal angle of the first submarginal 
cell is also blackened, while in the other species it is always hyaline. 
Middle cross-band broad at the end, filling the half of the second, 
and the whole of the third posterior cells ; basal cross-band distant 
from the apex of the discal cell. 
The left wing of the single specimen examined shows only two 
submarginal cells, the dividing veinlet being reduced to a stump. 
Type ? from West Nyasa, Choma, 4000 ft., May 1909 
(Dr. H. S. Stannus). 
46. Litorrhynchus rostratus, Loew (1860). 
Distinguished by the conspicuous tufts of black hairs 
on the sides of the thorax. The black basal band extends 
to the apex of the anal cell, or ends only a little before it.
