﻿610 Prof. Mario Ëezzi's È('.port on a Collection of 



8. Anastoechus mcridionalis, sp. uov. 



Ç . Length 10 mm. 



Very near A. nitiihdus 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 iipper and yellowish on the lower 

 portion. Antennae with the two basal joints red ; the third black, 

 not constricted at the base and tajjering into a long point. Scutellum 

 dark red. Squamae whitish and white-fringed ; haltères 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. nitididus, but the 

 first posterior cell a little larger. 



Type Ç, from West Nyasa, Mzimba, August 1909 {Dr. 

 IT. S. Stannns) ; 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. rctrogradus, Becker, also has 

 the ba?al joints of the antennae red. 



4. Disckistus, 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. Dischistiis diadcmatus, sp. nov. 



Ç . 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 

 hair.s, 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, 2h 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. Halterea
