scutellum with somewhat larger punctures. Metanotuiii finely rug-ose, 
the basal median area indicated, also the lateral carina?, and very 
indistinctly the petiolar area. Pleurae finely punctate, and metapleurae 
more closely so. First abdominal segment a little long-er than wide 
at apex, with two central carinae which extend to the middle of the 
second seg-ment, and with lateral carinae which extend nearly to the 
apex of the second. First and second seg-ments longitudinally rugose ; 
third scabrous, apical ones nearly smooth. Legs entirely bright ler- 
rug'inous, except the base of the anterior coxae, and the posterior tibiae 
and tarsi, which are deep black, the former with a white ring at the 
base. Spurs of posterior tibiae long, the longer one one-half the length 
of the metatarsus. AVings nearly hyaline, the veins and stigma dark 
fuscous, latter pale at base. Areolet very small ; transverse median 
vein in hind wing broken at the middle. Clypeus ferruginous ; man- 
dibles, except tips, yellow ; small lateral mark on mesonotum, tegulae,

Antenna? 28-jointed ; scape very thick, rounded, a little longer than the 
second joint, following decreasing very gradually to the tip. The 
antennae are pale browoiish yellow on the basal half, except the scape, 
above which is black like the apical part of the flagellum. Clypeus 
and mouth parts honey-yellow. Face stronglj^ raised medially, the
