than in front, the sides not very convex. The transverse contour of 

 the head, at the level of the eyes, forms a moderately convex and 

 regular curve. Occipital emargination fairly deep, deeper but 

 narrower than in punctulata. Occipitofrontal sulcus narrow and 

 deep. Anterior margin of clypeus emarginate in the middle. The 

 frontal carinae extend back as far as the level of the eyes, and 

 are slightly prominent. Frontal area depressed, the margins bounded 

 by a raised line. Scape of antenna extends back as far as the 

 posterior third of the head, all the joints of the flagellum longer than 

 wide. Eyes placed a little in front of the middle of the head. 

 Posterior lateral angles of the pronotum very obtuse, much less pro- 

 minent than in punctulata ; the profile of the pro-mesonotum is also 

 much less convex than in that species. The mesonotum has a shallow 

 transverse impression in front of the slightly tumid scutellar region. 

 Meso-epinotal suture not very deep. Dorsum of epinotum narrow, 

 longer than wide, margined at the sides and concave transversely. 

 Epinotal teeth directed upwards and slightly backwards, not as long 

 as the width of the dorsum ; declivity subvertical, a little shorter than 

 the dorsum. First node with the posterior face horizontal, the anterior 

 vertical, the dorsal edge slightly emarginate. Second joint subglobose, 

 feebly angular at the sides, narrowed behind, three-fourths wider than 

 the first and about as long as wide. • 



^ . 2"8-3 mm. Colour similar to that of punctulata, but the head 

 and thorax darker and more reddish-brown, or the body entirely dark 

 brown. Mandibles dark yellow, legs brownish-yellow. 



Pilosity longer and more abundant than in punctulata. Head 

 smooth and shining, the cheeks and temples sparsely striate longitudi- 

 nally, the spaces between the striae reticulate. Thorax more strongly 

 reticulate than in punctulata, the sculpture extending over the posterior 

 half of the mesonotum. Mandibles very finally longitudinally striate. 

 Anterior margin of clypeus shallowly emarginate in the middle, the 

 median area with a raised line in the middle which does not quite 

 reach the posterior margin of the clypeus. Scape of antenna longer 

 than in punctulata, extending by one-fourth of its length beyond the 

 posterior margin of the head (one-fifth in punctulata) ; 1st joint of 

 flagellum as long as the 2nd and 3rd taken together. Frontal carinae 

 slightly convergent behind, not widely divergent as in punctulata. 

 Thorax narrower than in that species, the dorsum of the epinotum 

 long. Mesonotum with a faint transverse median impression. 

 Dorsum of epinotum margined at the sides as in the 1/ , but less 

 sharply. First joint of the petiole with the peduncle quite as long as 

 the node, if not longer ; the node is thinner above and higher than in
