" $ . Like gallicola in size, and with the same brighter colour in 

 the $ minor and with more equal sized $ $ . Posterior half of the 

 head very shining and fairly smooth. Mesonotum without a median 

 tubercle in front. Epinotal spines longer than in gallicola. First 

 segment of the petiole with a quite obtuse protuberance below in 

 front, directed entirely forwards (not projecting out underneath). 

 Thorax somewhat more coarsely rugulose and more feebly constricted. 

 Otherwise similar.

$. 3-37 mm. Black; abdomen, antennae, legs and mandibles 

 dark brown or blackish-brown. Finely and very sparsely pubescent ; 

 pilosity absent except on the clypeus. Head smooth and shining, 

 sparsely and finely punctured, the clypeus, mandibles and sides in 

 front of the eyes finely striate longitudinally. Thorax longitudinally 

 rugulose above and dull (sometimes more strongly sculptured, almost 

 rugose), the sides of the pronotum shining, the mesopleura reticulate. 

 First segment of petiole fairly dull, very finely reticulate or coriaceous, 

 the 2nd segment and the abdomen smooth and shining. Head as 

 wide as long, very little narrower in front than behind, the posterior 

 margin straight, the sides very convex. Eyes placed in the middle of 

 the sides. Frontal area indistinct. The scape nearly reaches as far 

 as the occipital margin; all the joints of the flagellum longer than wide, 

 except the 3rd and 4th, which are about as wide as long. Seen in 

 profile, the anterior face of the pronotum is subvertical, its brow 

 rounded, the rest of the pronotum and the mesonotum flat. The pro- 

 mesonotal suture is very shallow, the meso-epinotal deep. Dorsum of 

 epinotum oblique, forming a continuous plane with the declivity. 

 Epinotal spines thin and acute, divergent, directed obliquely upwards, 

 a little more than one-third the length of the interval between their 

 bases. The mesonotal declivity is short and slightly concave trans- 

 versely. First segment of petiole ti-apezoidal, wider than long, the 

 anterior angles obliquely truncate, with a minute denticle on each 

 side in front of the posterior margin ; node of 2nd segment with a
