small, equally-spaced brown marks ; from the base to the tip of Ri about 

 19, these marks a trifle narrower than the hyaline interspaces , five large 

 brown blotches along the radial cells, the first at the base of vein M ; 

 second in m'ddle of cell R; third just before the origin of Rs ; fourth 

 over the fork of Rs, and the last at the tip of R2+3, irregular ; all the cells 

 with narrow brown marks across them producing a net-work. Venation 

 (see fig. p) : Sc short, Sc^ ending before the origin of Rs, Scg about 

 opposite it ; Scg longer than Scj ; Rs angular at base ; basal deflection of 

 ]Mi^2 lo"gj so that the inner end of cell ist Mg is almost on a level with 

 cell Rg; basal deflection of Cu^ before fork of M, sometimes far before ; 

 cross-vein ;;/ far out, so that the deflection of M^ is much longer than m. 



Abdomen, tergum, segments brown, darkest on caudal margin, paler 

 on the sides ; sternum dull yellow ; a dark brown median spot on caudal 

 margin of each sclerite.

Whitish ; mesothoracic praescutum with a broad median stripe and 

 two short lateral ones ; femora black, with a postmedian reddish annulus ; 

 wings with brown spjts, bands and seams. 



9. — Length, 6.5 mm (about); wing, 5.7 mm. 



$. — Head: rostrum and palpi dark brownish black, x^ntennœ, 

 basal segments yellowish brown, flagellum very dark brown, almost black. 

 Front, vertex and occiput pale, whitish, tinged with brown. 



Thorax : pronotum dark brown above, abruptly pale, yellowish white 

 on the sides. Mesonotum pale yellowish white, the median stripe broad, 

 dark brown ; the lateral stripes appear on the hind margin of the prsescu- 

 tum and run back across the scutum and scutellum ; at the caudal end 

 of the latter sclerite they unite and form a very broad median band, which 

 occupies the dorsum of the postnotum. Pleurae pale, whitish. Haltères, 

 knob and most of the stem dark brown. Legs : coxse and trochanters 

 yellowish brown ; femora black, with a distinct reddish annulus at about 

 three-fourths the length ; tibiae reddish at base, rest of tibiae and tarsi shiny 

 black. Wing with a slight yellowish tinge, especially in the cephalic cells ; 

 a very narrow brown mark from h caudad ; a brown mark from the tip of 

 Scj down beyond Rs ; a brown mark at tip of Ri and on r ; a narrow 

 seam along the cord; outer end of cell ist Mg seamed with brown ; most
