108 H. C. EFFLATOUN. 



the face is very short and flat ; peristoma narrow ; month small 

 and oval ; f rons much narrower than in the other species ; the ver- 

 tex and occiput are rather puf fed out and possess pale greyish pu- 

 bescence. Eyes entirely covered with dark grey hairs, which are 

 rather long and tufted. Antennas rather short, with the two basal 

 joints small, black and the third joint medium, rounded, rusty-red, 

 and possessing on the outside, some light, ashy-coloured dust; 

 arista blackish, quite bare and thin. 



Thorax longer than wide, entirely aeneous-black, rather shi- 

 ning and finely punctate ; it possesses the usual pair of whitish 

 lines on the front of the disc, which are rather inconspicuous and 

 scarcely extend beyond the middle; the pubescence on the disc, as 

 well as on the side margins and the pTeuras, is fairly long, pale 

 and even ; scutellum rather shining aeneous-black, punctate with 

 the lower margin flattened and somewhat blunt. 



Abdomen elongate, rather flat, but gradually tapering to- 

 wards the apex, where it is conical; it is shining aeneous-black, 

 except for the following markings: — two large yellowish-red spots 

 on the sides of the second segment, two much smaller and fainter 

 ones on the side margins near the apical corners of each of the 

 third and fourth segments respectively, and the apex of the fifth 

 segment which is also yellowish-red. The second segment possesses 

 two white lunules which are indistinct and obscured by the large 

 reddish markings in my type specimen ; these, however, Bezzi des- 

 cribes as "oblique, separated, but not dilated in the middle." The 

 third and fourth segments each possess two white lunules which 

 are distinct only in certain lights ; the lunules on the third segment 

 are oblique, slightly bent in their middle and with their upper 

 ends rounded, well separated and almost touching the basal margin 

 of the segment; the lunules on the fourth segment are distinctly 

 wider, with their upper ends rather more widely separated; their 

 upper three-fourths ran parallel with the side margins of the seg- 

 ment, then they suddenly bend outwards at right angles, thus their 

 lower fourth being parallel with the lower margin. Pubescence on 

 the abdomen is entirely whitish, dense and rather short. Venter 

 shining aeneous-black, but with the yellowish-red markings of the 

 dorsum showing through by transparency; pubescence very pale 

 and rather short. Ovipositor very small, retracted and with a small 

 tuft of rusty-yellow hairs. 



Legs shining blackish but with the knees and the basal halves 

 of the tibias yellow. All the tibiae and the tarsi bear strong spurs 

 and the hind femora, which are weak, possess from seven to eight 

 strong bristles on the ventral surface near the apex. 



Wings transparent, colourless, with the nervures strong and
