1945] Notes on Hippoboscidoe 93 
noted that Bustard and Sandgrouse, though not in the least 
related, are the only bird groups which have a pinkish under- 
down.” I suggest that Sandgrouse and Francolins act as facul- 
tative, and perhaps temporary, hosts for specimens of L. pilosa 
that hatch at the season when Bustards are absent. 
Bigot (1863, in Maillard, Notes sur File de la Reunion, 2d 
Ed., II, p. M3 8) includes Olfersia pilosa in his list of the Dip- 
tera of Reunion. If this record was based on a specimen taken 
in Reunion, it was certainly an erroneous identification.

Male. — Head seen in front about one and one-third times as 
wide as high; frons at its narrowest about twice as wide as the 
eye, measured along inner orbits distinctly shorter than its 
greatest width at vertex, the sides converging markedly from 
vertex to lower third and slightly diverging opposite fronto- 
clypeus; inner orbits (parafrontalia) broad, at their widest 
about half the width of mediovertex (frontalia), mostly smooth 
and shiny; frontal bristles moderately numerous, mostly placed 
in one irregular row; one very long and thick vertical bristle; 
postvertex (vertical triangle) rather long and wide, more than 
one-third of the length of mediovertex, transversely lozenge- 
shaped, the occipital margin nearly straight, the anterior margin 
straight and much longer than the sides, with a slight median 
triangular depression, but without pit; fronto-clypeus deeply 
notched medially at apex, the antero-lateral angles moderately 
produced. Palpi short, thick, slightly longer than fronto-clypeus 
(measured from ptilinal suture to apical notch), densely setulose 
and with one long bristle near the tip. Dorsal appendage of 
second antennal segment short and broad, its apical portion 
bearing many bristles, mostly curved downward. Thorax: an- 
terior margin nearly straight; humeral callosities fairly long 
and prominent, with broadly rounded apex; median notal and 
transverse mesonotal sutures deep, the transverse suture broadly 
interrupted medially. Scutellum semi-elliptical, less than three 
times as wide as its greatest length, the anterior (mesonotal) 
margin slightly convex, the hind margin very strongly and 
evenly so, the disk with a fine longitudinal groove. Thorax 
mainly bare; a few soft, short and long hairs, directed back-
