wards and is concave transversely. The margins of the mesonotum, 

 in front and at the sides, are rounded and project a little over the 

 vertical sides and front of the pronotum. The sides of the meso- and 

 epithorax are also vertical. The epinotum is very deeply excavated 

 from near its base above to its apex below, in such a way as to leave 

 a narrow wall on each side. Seen from above, only the edges of the 

 walls can be seen, so that the epinotum appears almost bispinose- 

 The declivity is margined by the downward continuation of the walls 

 and is vertical (in globulinodis the dorsum and declivity are oblique, 

 and only feebly marginate at the sides). 



* First segment of the petiole very strongly compressed laterally, 

 almost lamelliform except at the lower half behind, where it is a little 

 wider. It is produced downwards and is deeper behind than in front, 

 quite one and a half times deeper than long. Its dorsal surface is 

 rounded transversely, very narrow, almost linear. The 2nd segment 

 four times wider than long, and at least four times wider than the 1st, 

 the anterior margin concave, narrower behind than in front. Basal 

 half of the 1st abdominal segment depressed in the middle, the lateral 

 angles thereby rendered prominent and forming a more or less elongate 

 tubercle at each corner. Abdomen ovate, not much longer than wide, 

 rather flat above. 'Wings hyaline, nervures very pale. 



The structure of the nodes and epinotum may be made more apparent 

 by reference to the figures on Plate VIII.

5 . 3 "4-3 • 9 mm. Dark yellowish-brown, the posterior half of the 

 head and the thorax darker, legs, antennae, and mandibles paler, the 

 latter and the flagellum somewhat reddish. Very similar to trans- 

 versinodis, but larger and darker, differing from it also in the following 

 characters : 



Very finely and sparsely punctured, the head also very finely 

 rugulose. The pubescence longer and a little more abundant. The 

 sides of the head are much more convex, the posterior margin less 

 emarginate, the posterior angles less prominent and wider. Pro- 

 mesonotal suture obsolete, the meso-epinotal well defined. The 

 dorsum of the epinotum is proportionately longer and more convex 

 lengthwise, passing into the declivity by a much shorter and less 

 oblique curve than in transversinodis. The 1st segment of the petiole,
