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



yellowish colour. Colouring of the body in great part 

 reddish. 



The species of this group before me can be distinguished 

 as follows : — 



1 (2). The brown pattern of the marginal cell ends a little after the 



veinlet dividing the first from the second submarginal 

 cell and leaves therefore a fairly broad apical hyaline 

 space ........ basal is, Ric. 



2 (1). The marginal cell is filled up by the brown pattern to the end, 



or almost to the end. 



3 (6). The marginal cell is filled up by the brown pattern to its 



end and even a little beyond ; thorax black. 



4 (5). The bristles of the hypopleural tuft are all of a golden colour, 



or only a few are black; squamulae with the fringe golden 



nyasae, Eic. 



5 (4). Hypopleural tuft with black bristles ; squamulae fringed 



with argenteous . . . . argyrulepis, sp. n. 



6 (3). The brown tint of the marginal cell leaves at the end a small 



hyaline space. Thorax red, with black stripes. 



7 (8). The first posterior cell is broadly hyaline at the end ; thorax 



with three black stripes . . . ricardoi, sp. n. 



8 (7). The first posterior cell is filled with brown almost to the 



end ; thorax with two black stripes . dentiferus, sp. n. 



40. Litor rhynchus hasalis, Ricard o (1901). (Plate L, 



% 8-) . . . 



Four gigantic specimens, 20 mm. in length, and with 



a wing-expanse of 46 mm., all from North Nyasa, Karonga 



to Fort Hill, near Lufira River, May 30, 1909 {Dr. 



J. B. Dave;/). 



These specimens agree very well with the description ; 



but I think that this species is perhaps the same as 



macropterus, Loew (1860) ; the difference in the shape of 



the pattern at the base of the wings is very small. Loew 



records also a specimen of his species of eight lines in 



length. 



41. Litorrhynchits nijasae, Ricardo (1901). (Plate L, 

 fig. 9.) 



A specimen from North Nyasa, in bush near Vua, May 

 15, 1909 {Dr. J. B. Davey); compared with co-type by 

 Mr. E. E. Austen. Another smaller specimen from West 

 Nyasa {Dr. H. S. Stannus).
