610 Prof. Mario Bezzi’s Report on a Collection of 
8. Anastoechus meridionalis, sp. nov. 
?. Length 10 mm. 
Very near A. nitidwus and hyrcanus, but with very different 
antennae. Hairs on the upper side of the body greyish yellow, on 
the ventral side white. Head with white hairs, except those on the 
frons, which are black on the upper and yellowish on the lower 
portion. Antennae with the two basal joints red ; the third black, 
not constricted at the base and tapering intoalong point. Scutellum 
dark red. Squamae whitish and white-fringed ; halteres yellowish. 
The bristles on thorax and abdomen are yellowish. Legs yellow, 
with white pubescence and white hairs ; femora broadly black at 
the base, the hind femora almost entirely black ; bristles whitish 
yellow ; tarsi darkened at tip. Wings as in A. nitidulus, but the 
first posterior cell a little larger. 
Type 2, from West Nyasa, Mzimba, August 1909 (Dr. 
H. §. Stannus); the only specimen. 
This is the first Anastoechus recorded from the southern 
hemisphere ; the first posterior cell is larger than in typical 
forms. The North African A. retvogradus, Becker, also has 
the basal joints of the antennae red. 
4, Dischistus, Loew (1855). 
Of this genus, which is represented by very numerous 
species in Africa, there are in the collection only two 
specimens, which belong in my opinion to two new 
species. 
9. Dischistus diadematus, sp. nov. 
?. Length 6 mm. 
A small species, readily distinguished by the two silvery spots on 
the sides of fore margin of the frons at the base of the antennae. 
The body is clothed with golden hairs; only on the frons are 
there some black hairs; the bristles of thorax and abdomen are 
black. Head black ; frons shining in the middle, with black short 
hairs, covered on the sides by dense golden pubescence ; face clothed 
with wholly yellowish hairs; the silvery hairs form a transverse 
band (interrupted in the middle) at the insertion of the antennae ; 
occiput with short and dense hairs. Antennae black; the basal 
joints very short and black-haired; third joint long, not pointed, 
obtuse. Proboscis black, 2} mm. long. Thorax and scutellum 
velvety black, densely clothed with golden hairs; scutellum bearing 
eight strong black bristles on the hind margin, those of the middle 
decussate. On the pleura the hairs are of a paler tinge. Halteres
