In short, Trochopus may perhaps be on the way to developing into a new genus or subgenus, but it cannot be said, in my opinion, to have attained as yet to that point. 10. Corixa Kollarii (Fieb.)

Comparatively broad, length 2 ilì times greater than width: pronotum and clavus feebly rastrate, corium and membrane scarcely rastrate. Head and pronotum short, width of the latter 2 */> times greater than its length; lateral angles obtuse, rounded. posterior angle obtuse, sub- triangular. Metaxyphus triangular, somewhat elongate, not acuminate. Anterior femur incrassate, intermediate tibia one-half longer than tarsus, claw one-fifth longer than Fig. 3. — Face of Corixa Kollarii Fieb. r tibia and tarsus of te same 9.
