﻿G44 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 ; haltères with yellow knob. Scutelluni 

 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 E. 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 ^, from West Nyasa, Ekwendeni (Dr. H. S. 

 Stannus) ; a single specimen. 



61. Exofvosopa jacchoides, sp. nov. (Plate L, fig. 20.) 



(J. Length of the body 13 mm., of the wing 12 mm. 



A black species, with extensive black markings on the wings, 

 recalling that of E. jacchus ; the first abdominal segment bears on 

 the sides tufts of black hairs (not white, as usual). 



Plead 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 stronglj' 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 ; 

 haltères 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
