separated from it by the antenna? being much sliorter and 

 tliickcr, by the median area on tlie metanotum originating- at 

 the micidle of the segment — not at the base — and by the much 

 flatter scutellum. The body is stouter, as are also the legsj 

 tlie head is well developed behind the eyes and is there 

 obliquely narrowed ; the metanotal spines are not much 

 developed ; the mandibles have two unequal apical teeth ; 

 the clypeus is indistinctly separated from the face; the apical 

 abscissa of the radius is roundly curved upwards.

 Long. 16-17 mm. 



The twenty-one to twenty-two basal joints of the antennae 

 whitish yellow, stout, dilated beyond the middle, the apex dis- 

 tinctly attenuated, bearing an obscure, short, white pubescence; 

 the scape smooth, except for a few obscure punctures; the 

 ocellar region, a short line behind them, a narrower line down 

 the front, and the occiput black. The front and vertex 

 smooth, impunctate, the front ocellus surrounded by a deep 

 furrow; there is a shallower furrow down the front ; the face 

 and clypeus with a few scattered punctures, shining; the 

 clypeus with a few long fuscous hairs ; the apex of the clypeus 

 transverse, of the labrum rounded and sparsely covered with 

 long hair ; the mandibular teeth black. Mesonotum closely 

 and rather strongly punctured ; thickly covered with short 

 pale hair ; the sides narrowly at the base, the rest broadly 

 black, but the black does not touch the edge ; the scutellar 

 depression black. Scutellum flat, very smooth and shining ; 

 the apex sparsely covered with fuscous hair. Postscutellum 

 shining, obscurely and finely punctured ; tlie depression at 

 its base wide and deep, almost divided into two by the centre 

 being raised. The depression at the sides of the scutellum 

 wide, smooth, except for a few striations ; in front of tlie base of 

 the hinder wings the sides project into a blunt somewhat trian- 

 gular tooth. The basal half of the median segment is entirely 

 without keels, and consequently there are no areas, the base is 

 coarsely punctured, the centre broadly raised ; the apex has an 

 oblique slope and has in the centre a broad area (the posterior 

 median ?) in the middle ; this is rounded at the base and 

 bounded by a stout keel, which is larger and more distinct at 

 the base ; the area inside is smooth at the base, the apex 

 finely transversely striated, the rest filled up with three 

 rough, stout, irregular, longitudinal keels. The propleurae
