It is to be noted that in the <$ $ of this species, the 2nd-5th joints 

 of the flagellum remain separate, instead of being fused into one 

 joint, as is the rule in the genus.

$ . 4 - 3 mm. Very dark brown or black, the pro-mesonotum 

 somewhat paler or dark reddish-brown, the antennae, tibiae and 

 tarsi yellowish-brown, femora brown, mandibles brownish-red, This 

 race differs from the type of the species by its larger size, and by 

 the more angular junction of the pro- and mesonotum. The 3rd-6th 

 joints of the flagellum are as wide as long (wider than long in the 

 type). The head is also more coarsely reticulate between the striae, 

 and is also a little wider behind. The meso-epinotal suture is 

 indicated by a raised line. Otherwise like the type. 



9 • 5 mm. (Hitherto undescribed.) Pronotum moderately ex- 

 posed above in the middle, more exposed at the sides, the pronotal 

 shoulders subangular. Pronotum very coarsely and transversely 

 reticulate-rugose ; mesonotum and scutellum strongly and longi- 

 tudinally striate, the epinotum transversely striate, more closely and 

 finely so on the declivity than elsewhere. Dorsum of epinotum 

 sloping steeply downwards, slightly longer than the vertical declivity; 

 the epinotal teeth are represented by elongate tubercles, much smaller 

 than the teeth of the $ . Wings slightly smoky, nervures and stigma 

 pale yellow. Otherwise like the $ . 



$ . 4' 7-5 mm. Black, antennae, legs and mandibles yellowish- 

 brown. Head more or less lozenge-shaped, widest across the eyes, 

 wider in front than behind, without a distinct posterior margin like 

 that of the type, in which the head is shorter and wider behind. 

 Mesonotum very gibbous and convex in front, overhanging the 

 pronotum, which is thereby entirely hidden from above. Epinotum 

 unarmed, the dorsum merging into the declivity by a gradual curve ; 

 the declivity fairly steep. The 1st node is more pointed above than 

 in the type. Eyes very large and convex, occupying quite half of 

 the sides of the head, and almost touching the base of the mandibles 

 in front. As in the type of the species, the 2nd joint of the flagellum 

 in some specimens is redivided into two or more of its component 

 segments.
