basai half ; s.or.l, i.or.S: oc. very weak; ocp. distinct; ail the bristles 

 are black. 



Thorax and seutellum extremely shining black and almost free 

 from pubescence, however the few scatterod hairs which are présent 

 are black; ail the bristles are black. 



Abdomen entirely black, shining, with a short blackish pubes- 

 cence except at the apex where it becomes somewhat bristly; female 

 ovipositor longer than the two apical segments of the abdomen to- 

 gether, flattened, rather pointed at the tip and entirely shining 

 black; it possesses a very minute and inconspicuous pubescence. 



Legs with ail the femora black except the extrême tip dark yel- 

 lowish-brown; front tibiae and tarsi wholly yellow; middle tibiae 

 yellowish-brown and somewhat darkened for two thirds of their 

 length from the base but with the apical third yellow; hind tibiae 

 blackish except at the extrême tip yellow; middle and hind tarsi 

 wholly reddish-yellow; the. front femora possess below two rows of 

 about eight small black bristles each, one row on the outer and one on 

 the inner margin. The pubescence on the legs is fairly short and uni- 

 formly blackish. 



Wings black with six hyaline indentations and three hyaline 

 discal spots; the indentations are disposed as follows : one oblique, 

 before the stigma, extending from the costa and running to the 

 base of the wing and to the lower margin, covering more than the 

 lower half of the extrême base and the alula, being narrow above 

 and much broader below; two triangular indentations at the upper 

 margin, toward the middle, close to each other, the inner top angle 

 of the inner one touching the stigma; the vertex of both thèse trian- 

 gles always extends beyond R2 + 3 and the costa is yellow in cor- 

 respondance with thèse triangles, the vertex of the second triangle 

 being exactly above the radio-median cross-vein. The three remai- 

 ning indentations are at the hind margin and are almost eciuidistant 

 from each other; the first, which is the smallest, is oblong and 

 situated in the base of Cul cell with the apex well before M3 + Cul ; 

 the second, which is larger than the first is in the apex of Cul cell, 

 its apex touching M3-i-Cul; the third is in the base of 2nd M2 

 cell with its apex touching the middle of the médian cross-vein; it 

 is the longest and broadest of the three lower indentations, very 

 pointed at the apex and very broad 'at the base forming somewhat a 

 right angled triangle. The three hyaline rounded spots are : one 

 near the base of Ist M2 cell, its upper margin touching Ml ; one (the 

 smallest) in the upper half and at the apex of Ist M2 cell but never 

 touching any of the neighbouring veins; the third, which is some- 

 times oval, in the basai half of R5 ce41 in the middle; thèse spots are 

 somewhat variable in size, shape and rarely in position. Costal bristle 

 distinct although small; stigma deep black with its superior angle
