Cubital vein twice forked, the first time very far from its origin, which is near the middle of the proximal half of the space between the base of the first oblique and the stigmatic veins, the second time scarcely behind the base of the stigmatic vein. Second Oblique vein arising many times nearer the first oblique than the cubital vein and close to the former, the first discoidal cell between them about ten times broader on the hind margin than at the base.
