separated from it by the antenne being much shorter and 
thicker, by the median area on the metanotum originating at 
the middle of the segment—not at the base—and by the much 
flatter scutellum. ‘The body is stouter, as are also the legs; 
the 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. 
Xestojoppa olivacea, sp. n. 
Olivacea, apice antennarum lineisque mesothoracis nigris; alis 
fulvo-hyalinis, stigmate fusco. 9. 
Long. 16-17 mm. 
The twenty-one to twenty-two basal joints of the antennze 
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; the 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 the base of 
the hinder wings the sides project intoa blunt somewhat trian- 
gular tooth. ‘The basal half of the median segment is entirely 
without keels, and consequently there are no arew, the base is 
coarsely punctured, the centre broadly raised; the apex hasan 
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 propleure
