Extract

I. Cecidomyia spec. on Aristolochia sipho.

Flat rounded galls on the under side of the leaves, pale, somewhat transparent, pale greenish, 4 mil. diam. On the upper side of the leaf the gall becomes a slightly elevated disk marked with dark red and having in the middle a small pale-bordered hole. The galls grow larger and more globular on the stems of the leaves, to globes of 8 mil. diam., some more elongated, 18 mil. long and 8 mil. broad. The larvæ are brick red, 3 mil. long, very agile. I find no species on Aristolochia described by Osten Sacken and others.
