Lygus Chagnoni, n. sp.— This species of the genus Lygus is of a form near to L. pabulinus, Linn., in appearance.

It is ovate, convex bright green in living specimens, with irregular purplish-brown markings at the base of the membrane, smooth and without bristles, and a silky pubesecence on the sides of the pronotum, which has an orange-yellow border next the head, shading backwards in narrow lines into the green coloration, so as to make the reen appear in broad bands.
