•' $ . 1*5 mm. Yellow, legs pale. A few erect hairs around the 

 mouth and the apex of the abdomen, the rest of the body covered with 

 a short adpressed pubescence. Shining, epinotum and petiole sub- 

 opaque. Smooth, with a piligerous puncturation somewhat effaced. 

 Epinotum and sides of thorax very finely reticulate-punctate. Head 

 rectangular, one-sixth longer than wide, the sides moderately convex, 

 the posterior margin straight. The eyes occupy nearly all the second 

 anterior fourth of the sides of the head. Clypeus feebly excised in the 

 middle of its anterior margin, unarmed, the carinae reduced. Frontal 

 carinae sub-parallel. Mandibles with four teeth, the last very small. 

 Antennae 12-jointed; the scape does not extend back quite as far as 

 the hind margin of the head; 2nd-8th joints of the flagellum sub- 

 equal, wider than long, the 9th shorter and hardly wider than the 1st, 

 the 10th more than one-third longer and wider than the 9th, the last 

 joint very thick and nearly as long as the four preceding joints taken 

 together. Pro-mesonotal suture effaced on the dorsum, more distinct 

 laterally. Meso-epinotal impression pronounced, but less so than in 

 rhopalocerum. ' Profile of the pro-mesonotum fairly convex, that of the 

 epinotal dorsum less so, the junction of the dorsum and the declivity 

 forming a rounded but fairly distinct angle. The declivity is feebly 

 margined, and a little longer than half the dorsum, the latter dis- 

 tinctly longer than half the pro-mesonotum. Peduncle of the 1st 

 joint of the petiole half as long as the node, with a tooth below, at its 

 anterior extremity. Node triangular, rounded at the apex and below, 

 higher than long, hardly narrower than the 2nd node. The latter is 

 rounded and one-quarter higher and wider than the 1st. 



" This species belongs to the rhopalocerum, Em., group. In Arnoldi, 

 Forel, Bruunsi, Mayr, and speluncarum, Santschi, the erect pilosity is 

 more abundant, and the epinotum is smooth. In Schultzei and angus- 

 tinode, Forel, the colour is different ; in nltinode, Santschi, the petiole 

 is higher, and in termitobiiim&iid modestum the eyes are rudimentary."
