644 Prof. Mario Bezzi’s Report on a Collection of 
frons black-haired and with two black cross-bands. First joint of 
the antennae short, black and black-haired ; third joint in the shape 
of a short cone, of a greyish colour, bearing a style longer than the 
joint itself. Face projecting, the proboscis not projecting, Thorax 
black, with yellowish pubescence and with black hairs on the sides 
anteriorly ; mesopleurae with hairs of amaranthine colour ; meta- 
pleural tuft with white and below with black hairs. Squamulae 
dark, with a whitish fringe ; halteres with yellow knob. Scutellum 
black, with red margin and black bristles. Abdomen black, the 
second and third segments narrowly reddish on the sides; pubescence 
black, white and yellow; hairs on the sides alternately black and 
white. Legs dark reddish, black on the knees and on the last joints 
of the tarsi. Wing-pattern like that of EH. ignava, Loew, but with 
more indentations at the third, fourth and sixth longitudinal veins ; 
the upper corner at the discal cell is hyaline, and in this the species 
differs from all the others of the group D. Origin of the second 
vein a little before the small cross-vein ; first posterior cell broadly 
open, second and third of equal width, fourth broader than the 
others; a short stump in the discal cell before the lower apical 
corner. 
Type 2, from West Nyasa, Ekwendeni (Dr. H. 8, 
Stannus); a single specimen. 
61. Hxoprosopa jacchoides, sp. nov. (Plate L, fig. 20.) 
¢é. Length of the body 13 mm., of the wing 12 mm. 
A black species, with extensive black markings on the wings, 
recalling that of EH. jacchus; the first abdominal segment bears on 
the sides tufts of black hairs (not white, as usual), 
Head black: frons black-haired, the dark yellow tomentum 
forming a cross-band towards the middle. Antennae entirely black, 
the two first joints black-haired, the third of short conical shape, as 
long as the style. Face strongly projecting; proboscis as long as 
the mouth. Thorax black and clothed with predominantly black 
hairs, those on the collar being yellow; bristles black; pleurae 
black-haired, the metapleural tuft entirely black. Squamulae dark 
brown, with a white fringe, which is brownish in its exterior angle ; 
halteres dark, with whitish knob. Scutellum black, reddish at the 
hind margin, with black bristles. Abdomen black, reddish towards 
the sides and at the apex; the first and the following segments 
bear on the sides black hairs only; white scales are to be seen on 
the sides of the second, fourth, fifth and sixth segments, the third 
bearing an entire cross-band and the seventh being entirely covered 
with these scales ; there are also black scales in the middle of the
