coxae. The coxae and femora are punctured ; on the posterior coxae, behind, is a large

Antennae stout, the joints longer than broad. Head covered with a silvery white 

 pubescence ; front excavated, punctured ; the inner orbits of the eyes are yellow to the 

 ocelli, the outer orbits yellow in the middle ; mandibles and palpi yellow, the tips of the 

 former brownish. Thorax covered with a silvery white pubescence, coarsely punctured, 

 the punctures running into striations on the pleurae. Scutellum but slightly elevated. 

 Metanotum hollow in the centre, the upper area open at apex, the other areas not 

 defined. Petiole bordered at the sides, aciculated, the postpetiole strongly striated 

 longitudinally. Abdomen closely punctured all over, the apex blunt; the second 

 segment broadly yellow at the base, third with a narrow band contracted in the middle ; 

 the apices of the other segments bordered with yellow. The basal half of anterior 

 femora, anterior tibiae entirely in front, more than the basal half of four posterior tibiae, 

 the anterior coxae at the apex, and all the spurs yellow. There is a small yellow 

 roundish mark on the mesopleurae, and the tubercle beneath the tegulae is also yellow,
