wider and more convex behind. Eyes in the middle of the sides of 

 the head. Clypeus with two very small median carinae placed close 

 together, each ending in front in a blunt tooth. Scape very short, 

 half as long as the distance between the antennal sockets and the 

 occipital margin. Flagellum thick, the joints excepting the first and 

 last, wider than long. Pronotum rounded, as wide as long, flattened 

 above. The metanotum is nearly as long and as wide as the meso- 

 notum, the latter wider than long. The epinotum is fairly convex, 

 the dorsum as long as the declivity, the brow of the latter rounded. 

 The epinotum is as high as the mesonotum. The thoracic segments 

 are separated by deep sulci, but are not constricted. First joint of 

 petiole with a short peduncle, both joints short, thick, wide, and 

 roundly pyriform ; the 1st, excluding the peduncle, hardly longer than 

 wide behind, the 2nd much wider than long. Abdomen elongate- 

 ovate, fairly pointed posteriorly. Antennae and legs short and thick. 

 Very shining, very finely and shallowly reticulate ; head almost quite 

 smooth. Pilosity nearly entirely absent, only a few thin hairs round 

 the mouth and apex of abdomen. Pubescence very sparse. Brownish 

 black, legs and flagellum brown, mandibles and anterior margin of 

 the head brownish red. Scape, base of the flagellum, the ends of the 

 tarsi, and articulations of the legs yellowish. 



<$ . 47 mm. Wings clear. Clypeus produced triangularly in the 

 middle in front. Head oval, longer than wide. Petiole as in the $ . 

 Antennae blackish brown, margins of the mandibles reddish ; legs 

 brown, tarsi yellowish. All the rest of the body black, shining. 

 Much wider and with a wider petiole than clypeata, and with cruite a 

 differently shaped clypeus. The very strongly developed metanotum 

 gives this species a vei*y distinctive appearance."

 tarsi and articulations reddish brown, antennae reddish yellow, darken-

 Head, thorax, and abdomen microscopically rugulose, with a few fine 

 punctures ; the anterior half of the head rather closely but very finely 

 and shallowly punctured. Pubescence exceedingly sparse and micro- 

 scopical, except on the antennae, where it is dense and longer. Clypeus
