Rhodites lenticularis n.sp.

'Lentile-shaped galls in parenchyma of the leaves of Rosa lucida, showing on both the upper and underside and from 0.10 to 0.15 of an inch in horizontal, and 0.08 inch in vertical diameter. Comparatively few of the galls are single. Most are confluent and of irregular outline, and in some instances the entire leaf is covered, while in others the right or left lobe is thus covered. These galls resemble the European species R. spinosissimae, but the latter are more nearly globular and their vertical diameter is one-half more, while the horizontal is considerably less. The larval cell is much larger and the walls much thinner than in R. lenticularis...'
