not wider than long, feebly concave behind. Eyes in the middle of 

 the sides of the head. Clypeus feebly carinate; the frontal carinae 

 short. The scape almost reaches the posterior margin of the head ; 

 3rd-5th joints of the flagellum wider than long. No trace of a scrobe. 

 Thorax short; the profile of the dorsum hardly, or not at all inter- 

 rupted (more distinctly interrupted in the race depressum) . Epi- 

 notum with very small teeth. First node almost cuboid, as in 

 caesjritum, \sly . jnmicum, Smith. Clypeus, frons, cheeks, and thorax 

 finely and feebly longitudinally striate (sometimes indistinctly) 

 shining. The rest of the body smooth. Pilosity and pubescence as in 

 the other races. Brown ; legs and antennae brownish-yellow, abdomen 

 dark brown.

" Near the race depression, Forel, but much smaller, not so smooth 

 and without any emargination of the thorax, with a more cuboid 1st 

 node. Also closely allied to the var. pwnicum, Smith, but still 

 smoother and with the head depressed. Differs from pusillum, Emery, 

 by the short frontal carinae." 



The type species has a wide distribution, occurring over the whole of 

 Europe and the south shores of the Mediterranean.

^ . 17 mm. Pale ochreous yellow, the abdomen slightly brownish- 

 yellow ; the clypeus more reddish-yellow. Pilosity abundant, com- 

 posed of thin, whitish hairs, which are erect on the head, thorax and 

 nodes, oblique on the abdomen. Legs and antennae very sparsely 

 pubescent. Head, dorsum of thorax and the nodes nitidulous, finely 

 reticulate-rugose, the sculpture emphasised longitudinally on the head 

 between the frontal carinae, the sides of the head and thorax more 

 densely sculptured, almost rugulose. Abdomen smooth and shining, 

 and in some examples, with a golden reflection on the sides. 

 Head subquadrate, excluding the mandibles as long as wide, the 

 sides nearly parallel, the posterior margin straight, a little narrower 

 in front than behind. Eyes large, placed a little in front of the 

 middle, occupying about one-fifth of the sides of the head. Frontal 

 carinae divergent, extending back almost as far as the occiput, and 

 forming the upper boundary of the fairly deep and wide scrobes. The 

 latter are smooth and shining, divided into two parts over the basal 

 third, by a longitudinal ridge. Scapes as long as the scrobes; 1st 

 joint of flagellum as long as the 2nd, 3rd and 4th taken together, 

 3rd-7th joints quite twice as wide as long, the club one and a half 

 times longer than the rest of the flagellum. Mandibles shining
