;. EI'FLATOUiN. 



bi'istles are greyish-brown except the p.npl. and the pt. pale yellow; 

 the mpl. and the pt. are accompanied by some pale bristly liairs; 

 pubescence pale yellow. 



Abdomen entirely covered with a dense yellowish-grey tomen- 

 tiim and a pale yellow pubescence like the thorax ; the short latéral 

 bristles are yellowish but the longer apical bristles are usually brown ; 

 ovipositor very shining black and about as long as the two apical 

 ^-egments of the abdomen together ; its pubescence is pale yellowish on 

 the basai half, but brown and finer on the apical half. 



Legs entirely yellow to reddish-yellow; front femora with a row 

 of bristles beneath; middle tibiae with a single spur. 



Wings hyaline with a characteristic dark patch at the upper 

 margin near the tip, from which radiate several dark narrow bands; 

 the first of thèse bands arises from Ml, a little before the radio- 

 median cross-vein and extends upwards obliquely to the stigma, 

 touching El ; the stigma itself is usually yellow but there is a small 

 black spots on the costa at the base of the double costal bristle ; on the 

 upper margin there is a single short dark band which runs a little 

 obliquely from R2 + 3 to the costa, above the radio-median cross- 

 vein: the black patch covers the apical fourth of RI cell, (thus 

 leaving a fairly large triangular spot in the apical third of this 

 cell) more than the apical half of R3 cell leaving the inferior outer 

 angle hyaline and almost the whole of R5 cell except for two hvaline 

 spots at the base and the entire apex broadlv hyaline : the apex of 

 2ndM2cell is also hyaline but the dark patch extends over the upper 

 margin for two thirds of the length of this cell and gives rise to 4 

 narrow bands, 3 of w^hich reach the lower margin and the fourth in 

 Ist M2 cell only reaches M3 + Cul; the first of thèse bands is the 

 stoutest and shortest, the second intermediate in length between the 

 first and third, towards the middle of2ndM2 cell and the third isthe 

 longest and narrowest, covers the médian cross-vein and the extrême 

 tip of M34-Cul ; there is also a small indistinct isolated pale brown 

 spot in Cul cell on M3 + Cul ; the black patch contains, in addition 

 to the two fairly large and variable hyaline spots at the base of R5 

 cell, from 1 to 3 smaller hyaline spots, one of which in R3 cell, 

 touching R2 + 3 is always présent, but the other 2. very small. one 

 at the tip of RI cell and the other in R3 cell immediatelv below the 

 triangular hvaline spot in RI cell. are often absent; the outer latéral 

 margin of the dark patch is emarginate and often there is a fifth 

 short, narrow band arising from the lower angle of the patch and 

 extending over the apical part of Ml into 2nd M2 cell ; in the upper 

 half of the wing, the inner margin of the dark patch is liraited 

 above by the short oblique band in RI cell and below by a band run- 

 ning on the radio-median cross-vein; ail the veins are yellow, but 

 blaclcish in corres])ondance with the dark markings.
