New Species of North American Cynipidae (1890)

Neuroterus favosus n. sp.

Flattened, polythalamous galls on the leaves of Quercus tinctoria [velutina] varying in lateral diameter from one-fourth to almost an inch; they project from both surfaces of the leaf, but more prominently from the upper surface; their vertical diameter is not more than one-fourth of an inch. The upper and under surfaces, especially the first, bear a very close resemblance to a honey-comb. This resemblance is more striking after the insects have left, when the upper surface is literally full of holes. In general appearance they resemble the galls of N majalis Bass., but when green they are less succulent, and when dry they are of an extremely hard, ligneous texture, while the others are soft and pith like. I collected old galls in September, 1888, from a single oak tree in Rockport, Ohio.
