﻿618 Prof. Mario Bezzi's Report on a Collection of 



20. Mvlijhdainoeha puadiiieniiis, Wied. (1821). 



Some specimens which figree well with Loew's descrip- 

 tion ; but Loew says nothing about the patches of large 

 scales on the sides of the abdomen. The usual lengtii 

 is 14 mm. ; but one male measures only 10 mm. The 

 male genitalia are of large size, and wholly shining red. 

 Black tufts of hairs on the sides of abdomen are to be 

 found only on the second and fourth segments. The 

 single female has the hairs on the face whitish. The 

 wings show always the dark spot at base of the fork of 

 the third vein. 



Two males from North Nyasa, Karonga to Fort Hill, 

 near Lufira River, May 80, lUUi), and Akamanga, South 

 Rukuiu River, October 10, 1909 (Dr. J. JJ. Davcy); three 

 males and a female from Nyasahmd, Fort Johnston, 

 2,000 ft., June 1910 {Dr. A. H. 'Barclay). 



21. Molyhdamoeha incisvralis, Macquart (1840). 

 Agrees very well with Loew's description ot Anthrax 



mixtus (I860), which is without any doubt the same 

 species. 



Closely allied with the preceding species, but dis- 

 tinguished, by the want of large scales on the sides of the 

 abdomen ; by the male genitalia being black at the base 

 and without a black fringe; by the presence of black 

 tufts of hairs also on the sides of the fifth abdominal 

 segment ; by the want of the dark spot at the base of the 

 fork of the third vein. 



Three males from North Nyasa, Mulanasasa, Nchipomi 

 stream, September 16, 1909, and Mudumuka village, North 

 Rukuru River, August 25, 1909 {Br. J. B. Davey) ; a 

 couple from Nyasaland, Fort Johnston, 2,000 ft., June 

 1910 {Dr. A. H. Barclay). Two male specimens from 

 Non h Nyasa, Karonga to Fort Hill, near Lutira River, 

 May 30, 1909 {Dr. J. B. Davey), belong to the variety 

 mentioned by Loew (1860, p. 213, note 2), with the dark 

 spot at the base of the fork of the third vein. As the 

 male genitalia are, moreover, wholly red, as in M. jni/ncti- 

 pennis, I will give a name to this variety, calling it var. 

 inqnirenda, var. nov. ; perhaps a distinct species. 



22. Molyhdamoeba leacopogon, sp. nov, 



^ . Jjt-ngtli (two specimens), 9-10 mm. 



A grey species, with an oval elongate body ; very distinct on account 

 of the wholly whitish hairs of the face and the closed anal cell.
