Hagen.] 264 [Feb. 3, 



Mouth yellow, last joint of labial palpi blackish. Prothorax short, 

 narrower in front, yellowish, with a brown band in middle and one 

 on each side ; thorax yellowish, with a large but somewhat indef- 

 inite brownish band in middle and one on each side ; abdomen 

 (not in good condition) yellowish, with a broad black band in 

 middle and one on each side ; end of abdomen and appendages 

 yellow with black villosity, but it cannot be well made out. 

 Legs long, yellowish, claws black, first joint of tarsi a little 

 shorter than half the length of the tarsus. 



Front wings three times longer than broad ; front margin straight 

 in the basal two-thirds, then curved to form an elliptical apex; 

 hind margin curved, so that the greatest breadth is in the middle 

 of the wing ; subcosta and mediana yellow, the other veins brown ; 

 subcostal-space yellowish with a very faint tint of brown, which 

 passes above in the costal-space but only along the costals, so that 

 nowhere is an isolated yellowish spot in the costal-cells to be seen ; 

 34 costals between the base and the small milk-white pterostigma, 

 which does not reach the front margin ; beyond it a brownish cloud 

 to the tip ; the extreme base of the hyaline wing a little brownish. 

 Hind wings very narrow, the two basal thirds yellowish, more 

 brownish at the base, followed by along brown band ; apex white, 

 twice as long as the brown band, narrowed to tip. 



Female. Similar to the male ; head smaller ; eyes a little more 

 distant, vertex not depressed ; below it a narrow blackish middle 

 line to occiput ; a curved tranverse impressed line on occiput, on 

 each side with an impression near the eyes ; fovea open without 

 palpus ; antennae probably shorter, but not entirely perfect. I 

 find no other difference. 



I have no doubt that male and females belong together, though 

 two of them are a little larger than the male. All are from the 

 same place and collector, and the number given to them shows that 

 King had taken them to belong to his N. bacillaris. I believe that 

 all belong to the true N. Africana Leach, and as the type, accord- 

 ing to Walker, is still in the British Museum, this can be easily as- 

 certained. This species is undoubtedly N. latipennis Burm., also 

 from the same place and collector, and from the same lot of dup- 

 licata of which my specimens were taken. Leach's type is from 

 Sierra Leone, and he speaks about a specimen from Egypt, re- 

 ceived by Macleay from Savigny.
