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 . : ‘ : . basalis, Rie. 
2 (1). The marginal cell is filled up = 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, Rie. 
5 (4). Hypopleural tuft with black bristles; squamulae fringed 
with argenteous . ‘ argyrolepis, Sp. D. 
6 (3). The brown tint of the oneal 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 : : rm cearden sp. Nn. 
8 (7). The first posterior cell is filled an brown almost to the 
end; thorax with two black stripes .  dentiferws, sp. n. 
40. Litorrhynchus basalis, Ricardo (1901). (Plate L, 
fig. 8.) 
Four gigantic specimens, 20 mm. in length, and with 
a wing-expanse of 46 mim., all from North Nyasa, Karonga 
to Fort Hill, near Lufira River, May 30, 1909 (Dr. 
J. B. Davey). 
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. Litorrhynchus nyasae, Ricardo (1901). (Plate L, 
fig 99: 
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).
