narrower than in leucophyrus. The spots on the costal border are 
also not so numerous. The species is evidently variable and thus 
may only be a variety of leucophyrus. The type is in the British 
Museum (Nat. Hist.), presented by the describer. J am not 
sure if it comes in this genus, as the specimen is imperfect. It 
may be a Nyssorhynchus.

This is described from a balsam specimen, and the description 
is thus too incomplete to be of any diagnostic value. Really 
only the wing is described, and in balsam specimens scales, etc., 
get destroyed and may even have been damaged previously. Any 
way, Wings are variable, and it is just as unscientific to describe 
an insect from its wing as its leg or head alone. It is probably 
one of the species I have described from North Africa, so kindly 
sent me by French collectors. In the commencement of the 
description the author says “the two forks begin at an equal 
height ” (unless my translation is wrong); but in the photo 
(Fig. 15, Taf. II.) the base of the first sub-marginal cell is 
decidedly nearer the apex of the wing than that of the second 
posterior. 
The description is as follows :— 
The two forks begin at an equal height. There are.four small dark 
spots at the anterior margin of the wings; the marginal spots are 
missing on the branches of the superior fork and on the superior branch 
of the inferior fork. Three small spots on the sixth long vein. All the 
spots small and scanty. Joints of palpi with narrow light scaling.

anterior margin are small, of almost equal length, and extend evenly on 
to the first longitudinal vein; even the membrane itself is darkened at 
these places. Spot two reaches to the second long vein, on which there is
