646 Prof. Mario Bezzi’s Report on a Collection of 
second from the third posterior cell much shorter than the inferior 
vein of the discal cell and not placed on the same line with this ; 
discal cell obtuse outwardly, with the basal angle more or less 
developed ; small cross-vein placed at the middle or a little before 
the middle of the discal cell, the origin of the second longitudinal 
vein always taking place before it. Wing-pattern very simple, con- 
sisting only of a narrow brownish fore border and some small spots 
on the cross-veins. 
Of #. punctulata (= rasa) there are in the collection 
five very similar specimens from North Nyasa, Karonga to 
Fort Hill, near Chikweta’s village, May 31, 1909 (Dr. 
J. B. Davey); also a § specimen taken between Deep Bay 
and Vua, May 14, 1909, by the same collector. The spines 
of the female genitalia are yellow. 
64. Hxoprosopa major, Ricardo (1901). 
A single specimen from Nyasaland, Marimba, Kam- 
bindingo, January 20, 1910 (Dr. J. b. Davey), which 
agrees very well with the description of Miss Ricardo ; the 
original locality was Fort Johnston, also in Nyasaland.

but characterised by the red legs and different colour of the 
abdomen, 
Head red, with yellow tomentum ; a black spot on the occiput, 
near the vertex, sometimes wanting; frons with dense yellow 
pubescence towards the base of the antennae and very few black 
hairs near the vertex. Antennae short, the two basal joints red, the 
first bearing yellow hairs ; third joint black, a little longer than the 
style. Proboscis black, little projecting ; hind margin of the eyes 
very broad. Thorax black, clothed with short yellowish-grey hairs, 
absolutely without any black hairs, the bristles alone being black. 
Squamulae very large, dark red, with a yellowish fringe; halteres 
with whitish knob and reddish stalk. Scutellum red, with a com- 
plete row of strong marginal black bristles. Abdomen entirely red, 
without black cross-bands ; there are rounded basal black spots in the 
middle of the second, third and fourth segments, which are of decreas- 
ing size ; the first segment is black, with lateral tufts of whitish hairs. 
Venter covered with whitish tomentum. The hairs of the abdomen 
are very short and greyish, with scattered black hairs on the sides
