Black ; the antennae fulvous beneath ; face below the 

 antennae, white, and the basal joint of all the tarsi, and 

 the base of all the tibiae, yellow in the 3 ', face in the 

 ? with two yellow oval spots placed diagonally, the 

 tubercles yellow, and the base of the posterior tibiae 

 white. Head and thorax punctured ; the head in both 

 sexes, and in the 3 especially, much more closely than 

 the thorax. Eyes in the 3 converging much more 

 rapidly to the clypeus than in most of the species, and 

 the clypeus very narrow ; ? with the face shorter and 

 rounder than in most of the species. Scape of the 

 antennae simple in the 3 , not swollen or dilated. Abdo- 

 men dull in the 3 , and rather largely punctured, 

 especially on the basal segment, the puncturation of 

 the following segments closer and finer ; in the ? the 

 surface is more shining, and the puncturation is finer 

 and remote. Genitalia of the 3 with the stipites and 

 sagittae simple ; the stipites with long apical hairs. 

 (See pi. vii., fig. 5.) Length 4|- — 5j mm.

Easily distinguished from hrevicornis by the simple 

 scape of the 3 and the diagonal facial spots of the ? , and
