and widest at its posterior third. The dorsum of the epinotmn is not 

 clearly delimited from the declivity, into which it merges by an even 

 curve. The 1st joint of the petiole is not pedunculate ; it is very 

 convex above lengthwise, the dorsal surface, half as long again as 

 wide, is margined laterally and sharply delimited from the sides. 

 The 2nd joint of the petiole is widest behind, about as long as wide, 

 and one-third wider than the 1st joint. The abdomen is elongate, the 

 sides almost straight, the 1st segment a little longer than wide. 



$ . 9 - 2 mm. Similar to the £ , excepting the usual sexual diffe- 

 rences. The teeth of the clypeus are a little larger. The mesonotum 

 is wider than long, and one- quarter longer than the pronotum ; the 

 scutellum transversely oval, half as long as the mesonotum. The 

 dorsal portion of the epinotum is about as long as the mesonotum, 

 a little wider than long, and widest at the base ; the declivity is less 

 oblique than in the $' . The puncturation of the epinotum is stronger 

 than in the $ • Deflated .

$ . 6'7 mm. This differs from the type in its slightly smaller size 

 and darker colour, which is ferruginous brown, with the front of the 

 head, the abdomen, antennae, and legs yellowish brown. The punctu- 

 ration is slightly stronger, and the 1st joint of the petiole is more 

 convex longitudinally. 



$. 8'2 mm. (hitherto undescribed). Colouring similar to that of 

 the ^ . It differs from the $ of the type by the stronger punctura- 

 tion, especially of the thorax. The mesonotum is also narrower, and 

 as long as wide. The dorsum of the epinotum is distinctly shorter 

 and more convex. The 1st joint of the petiole is thinner at the base, 

 and is shorter and more convex lengthwise than in the type. There 

 are a few long pilose hairs on the back of the head and on the thorax. 

 Deflated, otherwise like the ^ . 



<$ . 8 mm. Head, thorax, and petiole piceous brown, the sides of 

 the scutellum and metanotum, the base and apex of the 1st joint 

 of the petiole, the anterior half of the head below, including the 

 frontal carinae, the mandibles, scapes, and 1st joint of the flagellum 

 dirty yellow ; flagellum brown, legs yellowish brown, first three 

 segments of abdomen dirty yellow, but brownish at the margins, the 

 remaining segments dark brown. Wings hyaline, nervures yellow, 

 stigma brownish yellow. The pubescence is much longer than in the
