612 Prof. Mario Bezzi’s Report on a Collection of 
Sisyrophanus has more affinity with Dischistus, notwith- 
standing the closed first posterior cell. The South 
African fauna is rich in species of Dischistus, which have 
an elongated cylindrical body, and this is to be seen 
also in the species of Sisyrophanus. 
In the collection are represented two species, which 
are both different from S. homeyeri and very distinct. 
11. Sisyrophanus leptocerus, sp. nov. 
dg. Length 11 mm. 
A species near S. homeyeri, but with black femora, wholly black 
abdomen and wholly hyaline wings. 
Head black ; face shining black, strongly and conically produced, 
bare in the middle, with long pale hairs on the sides; eyes touching 
for a considerable distance ; ocellar tubercle with some black hairs ; 
on the occiput and below the hairs are greyish. Antennae black ; 
the first joint shining, swollen; the second opaque; these two 
joints bear below some strong and long black and white hairs ; 
third joint opaque, as long as the first two together, much narrower 
than the first, attenuated at the tip, without distinct terminal style. 
Proboscis black, 5 mm. long. Upper facets of the eyes distinctly 
enlarged. Beard dense, white. Hairs of the thorax dense, short, 
greyish on the upper side, white below; thorax and scutellum 
black, without black hairs or bristles. Halteres yellowish ; squamae 
with white fringe. Abdomen black, clothed with hairs like those 
on the thorax ; hind margin of the segments with a row of long 
black hairs. Legs black, the tibiae dark reddish; bristles of the 
tibiae black ; hind femora without bristles, with a few white hairs 
only. Wings pure hyaline, with a small yellowish area towards 
the extreme base; veins yellowish ; costal cell dilated at the tip ; 
anterior branch of third vein very sinuose ; small cross-vein beyond 
the middle of the discal cell ; anal cell widely open ; first posterior 
cell very pointed at the end, 
Tyre 2, from Mbwabwa, Momberas, May 1909 (Dr. HS. 
Stannus); a single specimen, not in very good condition. 
12. Sisyrophanus pyrrhocerus, sp. nov. 
Q. Length 9 mm. 
A smaller and more cylindrical species, very distinct on account 
of the bright red third antennal joint and the yellow legs. 
Frons wide, shining black, with a grey band at the base of the 
antennae and some erect black hairs; face very prominent, black, 
very shiny, with a small yellowish spot at the posterior, lateral
