vertical declivity. Epinotal spines relatively shorter than in the $ , 

 hardly divergent, not directed upwards as in the $ , but nearly 

 horizontal. Nodes wider, the anterior dorsal margin of the 1st node 

 less convex than in the ^ • Wings tinged with dirty yellow, nervures 

 and stigma pale yellow.

$ . 35 mm. Differing from the type in the following characters. 

 The colour is darker, on the body quite black. The demiscrobes 

 are wider and deeper and more distinctly defined externally. The 

 sculpture of the thorax is weaker, and almost effaced on the middle 

 of the mesonotum. Pro-mesonotal suture obsolete, meso-epinotal 

 shallower and narrower. Epinotal spines shorter, hardly as long as 

 the dorsum of the epinotum, much more oblique and less divergent 

 than in the type. The dorsal (posterior-dorsal) face of the 1st node 

 is longer, a little longer than wide, and the 2nd node is longer and 

 more convex above. 



$ . Like the $ of the type but a little smaller. The sculpture 

 of the thorax is weaker, the anterior third of the mesonotum smooth 

 and shining ; the epinotal spines nearly horizontal. 



The resemblance of this variety to T. Grassi and its var. laevigatum, 

 Mayr, is even greater than in the type of the species. Joffrei and 

 Grassi are evidently very closely allied.

^ . 2 - 7-3 mm. Brown, legs, antennae, mandibles and petiole 

 brownish-yellow. Pilosity yellow, very sparse ; pubescence short, 

 oblique, very sparse and present only on the legs and antennae. 

 Head fairly strongly and longitudinally striate or striato-rugose, 

 the striae rather wide apart, the sides of the head reticulate- 

 rugose. Thorax longitudinally rugoso-reticulate, the rugae somewhat 

 discontinuous, the median portion of the mesonotum smooth. Head 

 and thorax moderately shining ; declivity of epinotum, petiole and 

 abdomen smooth and shining. 



Head subrectangular, about as long as wide, a little narrower in
