Egg.—Similar to egg of Clyton; nearly spherical, flattened at base, marked by 18 or 20 slightly prominent vertical ribs, and by many fine equi-distant striæ ; color yellow-green. Duration of this stage 6 to 7 days.

Young Larva.—Length .8 inch; cylindrical, tapering from segment 3 ; pubescent : color pale green, translucent; head twice as broad as next segment, sub-globose, bilobed, the surface thickly pitted with shallow excavations ; color shining yellow or ochrey-brown.

Tetanocera clara Lw. Mass., Conn. Specimens of this species with typical frontal markings, have the posterior transverse vein nearly straight and perpendicular, as in valida. In a single specimen there is an incomplete brownish-black abdominal stripe, interrupted at the incisures.

In the spring of 1880, while collecting Coleoptera, I secured a ♀ of a large species of Chalcid belonging to the genus Smicra, which is apparently unknown to the scientific world.

The specimen was captured on an oak shrub, in close proximity to an empty polyphemus cocoon. Could it have hatched from it ? This is not improbable, as Prof. C. V. Riley's Smicra mariœ was bred from this moth, and other species of the genus are known to be parasitic upon the larvæ of our larger moths.

Oria sanguinea, 9, fig. 613–614.

“Georgia.” This species has been generally recognized. Oria is used for maculosa in the Verzeichniss, from which sanguinea is distinct structurally. I have referred the latter as the type of Porrima in the Chheck List, No. 664. The doubtful reference there to Fitch's volupia must be struck out.

Cynips tenuicornis, n. sp.

Galls : Densely hairy hemispherical masses attached by a single small point to the upper or under surface of the leaves of an unknown species of oak found in Arizona. They are from one-half to three-fourths of an inch in diameter. One specimen in my collection is nearly globular, but all the others are hemispherical, the flat side lying close upon the surface of the leaf.
