The caterpillar of this species is brown, with small dorsal and lateral diamond-shaped yellow spots, emitting fascicles of hairs. It feeds, according to Abbot, on the cross-wort, corn, peas, wheat, &c. One of the caterpillars spun up on the 4th of April, and the moth appeared on the 29th. Another spun up on the 27th of May, and came out on the 16th of June. It continues breeding during most part of the summer. SPILOSOMA NAIS. Plate VII. fig. 3. ORDER: Lepidoptera. SECTION: Nocturna.

Phalæna (Noctua) Nais, _Drury, Append. v._ 2 HABITAT: New York; taken on the 24th day of June. _Upper Side._ The antennæ are black, and pectinated; the head and body are of a light yellowish brown. On the thorax are three black marks, running parallel with it, with several black spots on the abdomen. The anterior wings are black; the cilia of a light yellowish brown, which colour is continued along the interior edges, up to the body; some broad lines, of the same colour, occupy about two-thirds of the wing, running parallel with the anterior and interior edges. The posterior wings are of the same light yellowish brown, with a faint black spot on each, having a broad irregular border, of a faint black. {16}running along the external edges, being very narrow in the middle. All the wings are plain and entire. _Under Side._ Exactly like the upper, but the colours are less brilliant. This species is nearly related to our common British species, Spilosoma lubricepida.

Ennomos, _Treitschke, Duponchel_. GEOMETRA TRANSVERSATA. Alis angulatis fusco-fulvescentibus undique strigis minutis transversis fasciâque tenui communi obscurâ notatis. (Expans. Alar. 2 unc.) SYN. Phalæna (Geometra) transversata, _Drury, Append. v._ 2. HABITAT: New York. _Upper Side._ The antennæ are filiform, half an inch in length. The head, thorax, abdomen, and wings, of a brown orange. All the wings are angulated and besprinkled with small short transverse streaks parallel to each other. A narrow brown line, beginning at the external angle of the anterior wings, and running in a transverse direction, crosses them and the posterior wings near the middle, meeting above the extremity of the abdomen. _Under Side._ Exactly like the upper in every circumstance, except that the brown line is not to be seen.
