NEW ETHIOPIAN FRUIT-FLIES OF THE GENUS DACUS. 71 



sexes with the sutures partly obliterated. Legs pale yellowish ; front femora 

 brownish at the end ; four posterior femora broadly black at the end ; middle 

 tibiae black at the base exteriorly, hind tibiae entirely black ; praetarsi paler 

 than the other joints. Wings (fig. 6) hyaline, with blackish veins ; second vein 

 short, the fourth segment of the costa being about one-third the length of the 

 fifth ; third vein rather straight and parallel with the last portion of the fourth, 

 which is less curved near the base ; lower end of the small cross-vein placed after 

 the middle of the discal cell ; prolongation of the anal cell longer than the 

 remainder of the anal vein. The very reduced pattern consists only of the black 

 stigma, the infuscated marginal cell and an isolated blackish spot at the end of 

 the third vein ; there is no distinct grey spot at the end of the anal cell.
