tlie seven or ei^^Iit hairs ou the pteropleurao are deL-ideilly l)ristly; 

 scutellum tawny-yellow and bearing a very fine ])ulverulenee of the 

 same colour ; a.^r. convergent and crossed at the apex ; ail the bristles 

 are black except the pt. pale yellow. 



Abdomen entirely hlaek and covered with a very fine and thin 

 grey pulverulence which is tawny on the extrême apical margins of 

 the first four segments and on the apical third of the fifth segment; 

 the pubescence is very similar to that of the thorax, but with a few 

 longer hairs on the lower and latéral margins and, in addition, with 

 a few small black bristles on the lower margin of the fifth segment; 

 the short and flat ovipositor is shining black, the pubescence ou its 

 basai half lieing similar to that of the thorax and abdomen, but on 

 its apical half much finer and blackish. 



Legs entirely rusty-yellow with the usual black pubescence; the 

 front femora possess three rows of small bristles on the outer margin 

 and below, two of which are usually black and the third row pale- 

 vellowish; in addition, on the hind femora, there is one very short 

 l)lack bristle on the outer margin near the apex. 



Wings hyaline, but yellowish at the base, with one complète 

 transverse dark brown band and three or four spots on the upper 

 half; the cross-band is situated immediately after the middle and 

 extends from the Costa to the base, covering the radio-median and 

 médian cross-veins. to the lower margin; sometimes there are some 

 ])aler rounded spots in this dark band, especiallv in its upper half; 

 the dark brown spots are: one on the stigma, variable and usually ex- 

 tending from the costa over the 2nd costal cell to the base of R2 + 3 

 and R4 + 5; this spot is the palest, least conspicuous and is much 

 darker below than above; one covering the whole of the stigma and 

 extending downwards almost touching R2 + 3, usually this spot is 

 interrupted in the centre by a paler spot and its outer corner is very 

 often connected with the top of the cross band ; finally one large spot 

 on the apex of the wing, covering the apices of R2 + 3, R4 + 5 and 

 Ml ; this spot is extremely variable in shape, usually its lower mar- 

 gin is very emarginate. especially in the centre and with a small 

 rounded hyaline spot below the extrême tip of R2 + 3; sometimes it is 

 completely interrupted in the centre (i.e. the deep hyaline emar- 

 gination of the lower margin meeting the round hyaline spot below 

 the apex of R2 + 3) and thus giving the appearance of two distinct 

 ^pots: in addition there are three small, indistinct, pale l)rownish 

 s])ots, two on the lower side of and touching M3 + Cul and one im- 

 mediately beloAV Cu2-i-2nd A; ail the veins are vel'iow. but blackish 

 in correspondance with the dark spots and band ; costal bristle small 

 but distinct. 



Squamulae and haltères yellow.
