tibia darker ; abdomen brown ; posterior margin of segments darker ; wings grayisli 

 with brown spots and clouds ; the four brown clouds along the anterior margin are 

 the most conspicuous and are placed as follows ; The first opposite the inner end of 

 the basal cells ; the second over the subcostal cross vein and opposite the tip of the 

 anal vein which is also surrounded by a fainter brown cloud ; the third over the tip 

 of the auxiliary vein and the origin of the pra-furca ; the fourth over the marginal 

 cross vein and the tip of the first vein ; a brown cloud at the base of the submarginal 

 cell and over all the cross veins ; all the cells with small dots arranged in more or 

 less irregular rows ; tip of auxiliary vein a short distance beyond the origin of the 

 praefurca ; a second subcostal cross vein close to its tip ; posterior cross vein just be- 

 fore the inner end of the discal cell which is closed. Length, female 7 mm.;

 palpi dark brown ; first two joints of antenna; dark lirown, others much lighter brown ; 

 dorsum of thorax browni.sh yellow with three brown stripes, the lateral ones extend-

 halteres dark brown ; tips of knobs lighter brown, bases white ; legs yellowish ; 

 femora with a brown band before the apex ; abdomen yellowish with a brown band 

 on the posterior margin of each segment ; ovipositor short, reddish ; wings with a 

 whitish tinge, marked with many brown clouds and spots, those along margins being 

 largest ; the most important of these are as follows : one in the region of the hu- 

 meral cross vein ; one over the origin of the prrefurca ; one at the tip of the auxiliary 

 vein ; one just before and including the tip of the first vein ; one at the tip of the 

 second vein ; and one in the margins of the fourth posterior, anal, axillary, and 

 spurious cells ; other smaller spots are scattered over the surface of the wing, the 

 second basal cell containing more than any of the other cells ; all the cross veins are 

 broadly margined with brown and the tips of all the longitudinal veins are marked 

 with larger or smaller spots. Length, male 9 mm.; female lomm. ; wing 11 mm.
