 the origin of the antennae, except tip of mandibles, dull honey-yellow. 

 Autennse brown-black, often tinged with rufous above toward apex 

 and dull rufous beneath, except the two basal joints, four-fifths as long 

 as body, third joint, viewed laterally, four times as long as wide, joints 

 "A — 5 eijual in length. Tn two females the antenna? are ten-jointed, 

 the tenth slender and as long as ninth. Thorax, with the anterior 

 lobe above, a wide stripe on the disk of each lateral lobe, which is rare- 

 ly reduced to a mere dot on the whole of each lateral lobe, a spot at 

 the base and tip of scutel, the two sometimes confluent or subobsolete, 

 a small spot at the outer end of each cenchrus and a transverse gemi- 

 nate spot between them, the tip of metathoracic scutel, the front and 

 hind edge of basal plates or rarely its whole surface above, the whole 

 surface of the breast between the front and middle legs, or rarely two 

 large spots arranged crossways on that surface, all black. Abdomen, 

 with segments one and two, rarely edged at tip with black. Sheath 

 of ovipositor tipped more or less with black, the surrounding parts 

 sometimes more or less tinged with dusky. Legs bright honey-yellow;

 fous, as long as the body, vertically more dilated. Thorax (black,) 

 with the wing-scales and entire collare honey-yellow. Abdomen with 

 more or less of its sides, the extreme tip above and its entire inner 

 surface honey-yellow. In two % the middle submarginal cross-vein is 

 wanting, so that they might be mistaken for Euura."
