pubescence on the back. The wax-coloured markings are as follows : humeral calli 

 entirely ; a short and narrow stripe on each side of the transverse suture ; a very 

 broad, spot-like patch (about double as broad as the corresponding band of annulatus) 

 occupying almost the whole of the mesopleura and the adjoining part of the ptero- 

 pleura, ending with a small spot on the upper border of the sternopleura ; a single 

 rounded hypopleural spot. Mesophragma entirely black. Scutellum wax-coloured, 

 with a very narrow, black, basal stripe. Halteres whitish. All the bristles are black ; 

 no trace of anterior supra-alars : pteropleurals weak ; scapulars not distinguishable 

 in the type ; two scutellars. Abdomen ovate, punctate and pubescent like the 

 pronotum, a little constricted near the base ; it is black, but has a broad yellowish 

 band at hind border of second segment, like annulatus, and besides a broad yellow 

 middle band extending from hind border of second segment to the end, where it is 

 dilated and occupies almost the whole hind half of the last segment ; along the 

 middle of this yellow band there is a narrow black stripe, dilated at base and attenu- 

 ated before reaching the tip ; the sutures of the segments are partly fused and the 

 third is not ciliated at the sides. Venter yellow, with dark or blackish sides ; geni- 

 talia reddish. Legs with the coxae entirely of a pale yellowish colour, the ends of 

 the femora and the four apical jomts of the tarsi being a little reddish. Wings (fig. 3)

hyaline, with brownish veins ; second vein short ; small cross- vein a little beyond 

 the middle of the discoidal cell ; last portion of fourth vein gently curved at base ; 

 prolongation of the anal cell proportionally short. There is a narrow blackish 

 fore border, which leaves the costal cells hyaline, but is more intensively coloured on 

 the stigma ; below this, the fore border is dilated, filling broadly the base of 

 the submarginal cell and surrounding the upper end of the small cross-vein ; at 

 its end the marginal band is a little dilated, but without forming a distinct spot at 

 the end of third vein. There is no trace of an anal stripe, the anal cell being only a 

 little yellowish on its upper half. 



Type <J, and an additional specimen of same sex, in the writer's collection, taken 

 near Ghinda, Erythraea, December 1916, by Dr. Alberto Mochi, in whose honour 

 the species is named. 



4. Dacus woodi, sp. nov. 



Exceedingly close to the preceding species (D. mochii), and resembling it in its 

 unspotted face and unciliated third abdominal segment of -the male, but differing in 

 the colour of ^ody and in the not infuscated upper end of the small cross-vein.
