Hymenoptera Orientalis. 263 



projecting, thick, much broader than long, slightly incised 

 at the apex ; the apex with five teeth ; the central and 

 outer sharply pointed, the other two broader and truncated 

 at the apex. Third antennal joint not much longer than 

 the fourth and not twice the length of the second. The 

 punctuation on the head is close, moderately strong ; the 

 pubescence short and sparse. Thorax opaque, aciculate, 

 and bearing widely separated shallow punctures, those on 

 the median segment more widely separated than those on the 

 mesonotum. Triangular area of median segment opaque, 

 finely and closely rugose, channelled down the middle. The 

 oblique furrow on the mesopleura is wide, deep and obliquely 

 striolated ; the metapleurae finely obliquely striolated ; 

 median segment short, its apex obliquely and rather 

 abruptly rounded. Petiole longer than broad, dilated slightly 

 in the middle, clearly separated from the second segment, 

 and covered with moderately large punctures. The other 

 segments are similarly punctured, the punctuation becoming 

 sparser towards the apex. Pygidial area opaque, irregularly 

 and slightly reticulated, much narrowed at the base, the apex 

 rounded. Incision on hypopygium extending beyond the 

 middle, rounded at base, of nearly equal width throughout. 

 The flagellum is rufo-fulvous beneath, the inner orbits of 

 the eyes, the antennal tubercle, the pronotum, metanotum, 

 the third abdominal segment, except at apex, and a 

 band occupying the apical half of the fifth segment, rufo- 

 yellow.* Legs inclining to piceous ; the anterior knees, 

 tibiae and tarsi, yellow in front ; the spurs white ; the spines 

 blackish. The second recurrent nervure is almost interstitial ; 

 second cubital cellule rather shortly pedunculated ; the 

 apical nervure longer than the basal. The wings, although, 

 dark smoky throughout, are darker along the radial cellules. 

 Length 8 mm. 



* I suspect that the rufous tint is caused by cyanide of potassium.
