The venation (Figs, i and 2), is typical of Parasemi- 

 dalis, i.e. the cross-vein from M to Cu, strikes the 

 former on the stem and not on M3+^ in both pairs 

 of wings. The cross-vein from R^ to Rs strikes the 

 latter on the stem Rs, except in the right hindwing, 

 vv^here it strikes Rs just out on Ra+a- This character 

 is variable, see below. Where I A meets the margin 

 of the forewing there is a slight indentation. This is 

 more or less distinct in other specimens. 



The abdomen is stout, with wax-secreting areas 

 arranged typically. The apex is more strongly chitin- 

 ised and dark brown (Fig. 5). The lateral valves 

 or paraprocts are narrow, as shown, and their dorsal 

 attachment is peculiar. Lateral hooks are present. The 

 sub-genital plate is small. The penis sclerites (shewn 

 shaded with cross lines) are fused distally round the 

 penis.

Habitat. — Wadi Digla, near Cairo, Egypt; March 

 1923. Taken at light by Mr. C. B. Williams. 



HoLOTYPE cf in British Museum (Nat. Hist.). 



Thirteen specimens, all males, were taken by 

 Mr. C. B. Williams. These shew variations from the 

 type mainly in the wing-venation, but there is also 

 variation in colour of the body, and a slight variation 

 in the number of antenna] joints, tarsal ratio, ar- 

 rangement of setae &c. The colour is probably of 

 little significance, and abdominal coloration from pale 

 yellow to almost black occurs.
