median segment, and apical three segments of the abdomen black ; 

 the teculsB of the wings, the legs, and the basal three abdominal 

 segments red ; the whole insect covered with a rich glittering 

 golden pile, forming tesselated transverse bands on the apical 

 margins of the abdominal segments ; wings light flavo-hyaline, 

 nervnres testaceous.

5 . Head and thorax pruinose ; abdomen smooth, dull and 

 opaque ; the clypeus rounded in front, the extreme anterior 

 margin narrowly smooth ; the front with a medially impressed line 

 leading down from the anterior ocellus, two slight lateral hollows, 

 one on each side of the line, and a shallow pit behind the 

 posterior ocelli ; median segment long, rather compressed, steeply 

 sloped posteriorly, above transversely striate and covered with soft, 

 short, thin pubescence ; abdomen narrow, the apical segments 

 narrowing acutely to the apex. Black ; the mandibles, the scape 

 of the antennae in front, the femora, tibite, and tarsi of all the legs, 

 the basal two and the apical segments of the abdomen red ; the 

 clypeus and front, and the posterior margins of abdominal 

 segments 1-5 clothed with dense silvery pile, the pygidial area 

 studded with a thin yellowish pubescence ; wings hyaline, yellow 

 at base, broadly pubescent along the apical margins.

This is quite an aberrant species, having affinities to Larra 

 and Tachysphex; it has the front and the median segment of the 

 former, while the armature of the fore tarsi is that of Tachg- 

 sphex, but the pygidial area is pubescent and the general appearance 

 that of a Tachytes.

$ . Head broader than the thorax, sparsely punctured, thorax 

 and abdomen smooth and shining ; the vertex sparsely, the 

 clypeus, front, cheeks, sides of the thorax, the median segment 

 above and on the sides and apex, and the abdomen densely pu- 

 bescent ; clypeus transverse, its anterior margin slightly recurved ; 

 vertex marked with a shallow V-shaped furrow ; mesonotum 

 anteriorly with two parallel abbreviated impressed lines ; median 

 segment above indistinctly transversely striate, the sides obliquely. 

 Black ; the mandibles, the femora, tibia? and tarsi of the legs, and 

 the basal three segments of the abdomen red ; the pubescence 

 glittering silvery white, forming transverse bands on the apical 

 margins of the abdominal segments ; pygidial area clothed with
