2nd node of the petiole, which is narrower and lacks the flattened 

 and translucid upturned edge at the sides. The spines are also a 

 little shorter." Abdomen smooth and shining, and in some examples 

 also very faintly rugulose over the 1st segment. 



$ . 6 mm. Somewhat lighter than the £ > more reddish-brown, 

 especially the thorax, nodes, and legs. Pronotal angle only just 

 visible from above, prominent but not acutely angular as in the ^ . 

 The mesonotum is longitudinally striate, the scutellum and epinotum 

 transversely striate, the striae on the former more or less concentric. 

 The head is as wide as the thorax, not considerably wider as in the 

 case of the ^ . The 1st segment of the petiole differs from that of 

 the ^ in not having a dorsal face. It is very comrjressed from front 

 to back, almost laminate throughout, so that the posterior surface 

 forms one continuous and oblique face, from the dorsal edge above to 

 the ventral edge below. The 2nd node, four times wider than long, 

 4s on the contrary less rounded above, so that the anterior and 

 posterior faces meet above in a fairly acute angle ; the dorsal edge 

 formed by the junction of the two faces, is slightly sinuate, curving 

 forwards at the sides. Epinotal spines shorter and less acute than 

 in the ^ , and only very slightly divergent, very little longer than 

 their basal width, and hardly longer than half the interval between their 

 bases. Wings tinged with yellow, nervures and stigma pale yellow.

The description of the petiole in the type of the species is not very 

 clear, and requires amendment. 



The 1st node is more or less squamiform, but much thicker above 

 than below, so that there is a distinct, but short, dorsal face. This 

 meets the almost vertical posterior face at right angles. The dorsal 

 face becomes narrower, i. e. thinner, laterally and is curved down- 

 wards and is continuous with the sides of the node or squame. The 

 sides end below in somewhat projecting and obtuse angles, which are 

 turned a little bit forwards. The 2nd node, which is fairly convex 

 transversely, has the .posterior third of its sides strongly flattened 

 dorso-ventrally (laminate), so as to form a trenchant' edge at its 

 lateral margins.
