Related to D. guttula, Alexander (Portuguese East Africa) 

 general coloratiou yellowish brown ; thoracie pleura with 

 a broad dark brown longitudinal stripe ; wings grey with a 

 sparse brown dotting along the veins; Sc short; cell \st M^ 

 irregular in shape, lying far out in the wing-membrane. 



Male. — Length 4*8 mm. ; wing 5*5 mm. 



Female. — Length 5 mm. ; wing 6 mm. 



Rostrum and palpi dark brown. Antennae short, dark 

 brow^n ; basal flagellar segments subglobular, gradually 

 passing into oval. Head greyish pruinose.

 femora yellowish brown, the extreme tips indistinctly paler; 

 remainder of the legs brown, on the tarsi passing into darker 

 brown. Wings grey with a sparse brown pattern that is 

 confined to the veins, the principal spots as follows : at tip 

 of Sc and origin of Rs ; fork of Rs ; tip of i?i ; along 

 cord ; at tips of longitudinal veins ; one before mid-length 

 of M and another less distinct spot before the end of M ; 

 a series of about three small spots along Cu ; an indistinct 

 series in cell C ; two spots along vein 2nd A ; wing-axil 

 darkened; veins pale, darker in the infuscated areas. 

 Venation : Sc short, Sc^ extending a short distance beyond 

 the origin of Rs ; Rs about equal to the deflection of R^^^ 

 and approximately in alignment with it, both gently 

 arcuated ; cell 1*/ M^ very irregular, situated far out in the 

 membrane ; inner end greatly arcuated, about as long as the 

 basal deflection of Cu^ ; m short, from one-third to one- 

 quarter the length of the outer deflection of M^ ; basal 

 deflection of Cu^ at or some distance before the fork of M. 



Abdomen brown. Male hypopygium Avith the ventral 

 pleural appendage relatively small but fleshy ; dorsal pleural
