almost imperceptible (hist tarsi of liind legs absent). Ungues equal (simple?). Wings 

 rather densely scaled vvitli lung lateral, rather broad, scales, and with short broad median 

 ones, first sub-marginal cell longer but scarcely any narrower than the second posterior cell, 

 its base about level with that of the second posterior cell, its stem about two-thirds the 

 length of the cell ; stem of the second posterior cell nearly as long as the cell ; posterior 

 cross-vein sloping towards the base of the wing, about three times its own length distant 

 from the mid cross-vein ; the branches of the fifth long vein very long, the cell being nearly 

 as long as the stem ; fringe long and dense, especially at the apex where the scales are broad 

 and sword-shaped ; the median sized fringe scales slope across the long ones. 



Length. 3'5 mm. 



Habitat. Bahr-El-Ghazal (Major Bray). 



Time of appearance. September (1905). 



Observations. In general appearance this species is just like the Stegomyia Scutellaria 

 of Walker. It was nearly placed on one side as such, but luckily the flat scales on the 

 mesonotum at the sides of the bare space in front of the scutellum were noticed. The 

 median silvery line also shows a central, dark, thin line, not seen in the Eastern species, nor 

 are the two small thoracic spots. There are also marked peculiarities in the wings, palpi and 

 antennas, so that it must clearly be placed in a new genus. The specimen bears a note, 

 " bred from a tree," presumably from a larva taken in a hollow tree. It is said to be a very 

 irritating species. 



The hind legs were too damaged to describe. The specimen was collected by 

 Major Bray. Stegomyia scutellari.-i (Walker) is also a tree and bamboo breeder.

This species has been found again 

 in the Sudan, and Mr. Willcocks sends 

 me many from Egypt. 



Larva; and pupae have been foimd 

 in Khartoum, and are described here 

 as they have not previously been 

 examined and figured. 



The specimens are badly mounted 

 so that only a few characters can be 

 given.
