 Bull. Soc. Vaud. Sc. Nat. vol. 50, p. 249, §, 1914. 



Q|. 16-17 mm. Head varying from brownish red (burnt sienna) 

 all over, to reddish brown and becoming paler towards the posterior 

 margin. Mandibles dark reddish brown. The flagellum, the thorax 

 and petiole entirely brownish red or burnt sienna, the upper sur- 

 face of the thorax a shade darker than the lower part of its sides. 

 Tibiae, tarsi and scapes dark reddish brown. Abdomen brownish 

 black, the apical margins of the segments pale flavous and translu- 

 cent, the spots of a dark reddish ochreous, large and fairly sharply 

 defined, those on the 3rd segment very little smaller than on the 

 2nd. The sculpture of the head is a little stronger than in the 

 type of the race and distinctly more so than in the type of 

 the species. 



Head as long as wide, the posterior margin more deeply emar- 

 ginate than in the type of the race, and also differing from the 

 latter (in which the sides are continuously convex), by having the 

 middle third of the sides straight. The mandibles are also longer 

 than in the race, being half as long as the head. The lateral angles 

 of the lobe of the clypeus are sharply rectangular, (much more than 

 a right angle in the type of the race). The meso-metanotal and 

 meta-epinotal sutures more deeply impressed than in the race. The 

 dorsum of the epinotum is wider and less oblique, forming with the 

 subvertical declivity a continuous curve; the declivity as long as the 

 dorsum, (shorter in the race). Convexity of thorax, L. = 4 H. 

 Scale of petiole thinner, less convex in front, the sides moderately 

 convex, (almost straight in the race). 



§ media, 12*2 mm. Colour as in the Qj. but a little paler. The 

 spots on the basal half of the first abdominal segment extend right 

 across it, (separated by a narrow median line of black in the Oj.), 

 the 3rd segment is entirely black. The head is like that of the 

 ^ media of the race but is widest behind the eyes and not in the 

 middle ; the posterior margin is much wider than in the type of the 

 race, and very shallowly emarginate. The clypeus is more sharply 

 carinate, the lobe longer and rectangular. Scale of petiole higher 

 and less convex in front than in the race. 



§ minor, 8-9 mm. Head, thorax and legs ochreous or reddish 

 ochreous, the antennae and tarsi reddish brown. Abdomen brownish, 

 the pale markings dull ochreous and diffuse. Sides of the head in 

 front of the eyes parallel, behind the eyes convergent and modera-
