 »Nigra, facie et fronte laevis, nitidis; petiolo apicali coxisque posticis punetatis; 

 alis fere fumatis. $ Long. 11 — 12 mm. 



The lower part of the face, the pleurae, the metanotum, the apical three segments 

 of the abdomen above, and the third antennal Joint are densely covered with a silvery- 

 withe silky pile ; the legs are less densely covered, and the pile on them is darker; the 

 pile on the other parts of the thorax is much shorter and fuscons; the petiole has a 

 short fuscous pile; and the rest of the abdomen, except the apical segments above, is gla- 

 brous. The antennae are thickened towards the apex; the scape is as long as the third 

 Joint, the latter being longer than the following two joints united; the fourth Joint is 

 ionger by about one sixth than the fifth Joint. The eyes one are more or less greenish. 

 The face is rather sharply carinate; and there is a less well-defined keel on either side, 

 this keel being placed nearer to the eyes than to the central keel. The front below the 

 antennae projeets and is margined; above the antennae it is depressed. The head is 

 faintly alutaeeous, almost shining. The pronotum is deeply excavated, the sides of the 

 excavation margined. The mesonotum is almost opaque; the sides are margined and 

 have a furrow on the inner side of the margin; the parapsidal furrows reach nearly to 

 the base, and are moderately deep and curved; the surface bears large distinctly separat- 

 ed punetures, the sides being minutely striated. The scutellum has a somewhat in- 

 distinet furrow in the centry and is, if anything, more strongly punetured than the meso- 

 notum. The mesopleurae are covered with large shallow punetures, except a large 

 space in front. The sternum is apparently impunetate, and densely covered whit silvery- 

 white pile. The metanotum is largely rugosely reticulated, the mesopleurae less strongly 

 so; the lateral furrow is wide, and bears oblique wingset-apart keels. The petiole is as 

 long as the upper part of the following three segments united, opaque, impunetate at 

 the base, densely covered with fuscous pile; the apical half bears large punetures. The 

 long hind legs are opaque; the tarsi bear a few stiff bristles on the underside; the spurs 

 are a little more than one third of the length of the metatarsus; the claws on the under- 

 side are rufous; the coxae are pitted sparselv towards the base and beneath; the meta- 

 tarsus is a little longer than the second and third joints united. The wings are more or
