in front. Mesonotum wider in front than behind, as wide as long, 

 and twice as long as the pronotum. Scutellum ovoid transversely, 

 one-third as long as the mesonotum. Dorsum of epinotum rather 

 short, twice as wide as long, the declivity much less oblique than in 

 the $ : seen from in front, the brow of the declivity is feebly but 

 distinctly concave from side to side. The node of the petiole is 

 thinner above than in the $ . Abdomen elongate, very nearly as 

 long as head and thorax together. Dealated. Other characters as 

 in the $ .

g . 2-5 mm. Head, thorax, and legs reddish yellow, the head 

 ■somewhat redder ; abdomen brown-yellow, the 1st and 2nd segments 

 •dark brown with the basal margins paler. This species is very 

 similar to spei, from which it is clearly distinguished by the following 

 characters. 



Head much longer proportionately than in that species, one and a 

 quarter times as long as wide. Eyes very minute ; flagellum more 

 incrassate. The clypeus has a bisinuate anterior margin as in spei, 

 but is convex from side to side, and rather abruptly raised in the 

 middle so as to form a sub-carinate hump below the frontal carinae. 

 The epinotum is proportionately wider than in spei, and the declivity 

 is not sub-margined laterally. The abdomen is impunctate.

" $ . 2'4-2-8 mm. Yellow, slightly reddish, head more or less 

 dark brown, thorax brownish red or yellow. Legs, mandibles, 

 antennae, and abdomen always paler. Meso-metanotal suture very 

 deep. The scape does not quite reach the occiput. Node of petiole 

 very much as in the type form ; the clypeus is shorter and the 

 mandibles longer.
