Although Cossus centerensis has only recently been discovered, it must have existed for many years in the vicinity of Center, N. Y., its present home. More than twelve years ago, while riding in a Central R. R. coach, I noticed certain species of Poplar, the central shoot of which had perished from causes then unknown; later, while on an Entomological tour near the same place, I found a group of the Populus tremuloides which were similarly affected, as were also many other trees of the same species in the vicinity.

L. Murtfeldtella Cham.

Miss Murtfeldt favors me with the following notes upon the larva of this species : “It feeds in the flowers of the Œnotheras both wild and cultivated, and is especially destructive to Œ. Missouriensis, which is now extensively cultivated.

Anisota bisecta, nov. sp.

♀. Head sunken ; head and collar tawny. Antennæ short, simple, the joints showing as distinct rings. Thorax robust, globose, elevated in front, and projected over the head more than in A. bicolor or in A. Heiligbrodti. Shoulder-covers narrowly bordered above with brown. Abdomen short, not extending beyond the hind wings, concolorous with them.

On two occasions I have observed Allantus basilaris (Say) Nort. ♀ devouring another insect; in one instance the larva of a Chrysopa, in the other a small flower beetle of the genus Phalacrus. Although no such habit has been recorded previously in regard to any American species, it does not appear to be entirely without precedent among the European members of this family, for, according to Westwood, (Introd., ii., 109) “Various species, however, (T. viridis, scalaris, etc.) attack and devour living insects which frequent the same plants, as observed by St. Fargeau (Ann. Soc. Ent. France, 1834, p. 11) and Dahlbom (Prod. Hym. Scand., p. 38).”

Catocala sinuosa, n. s.

This species is allied to C. coccinata, but very distinct from that and all other described species. Fore wings whitish gray, paler, but lines much as in coccinata.

Demonstrations from examples taken by me during the past three years, and from examples taken in Farmington, Conn., twenty years ago, give indubitable evidence that our Limenitis are plastic forms of one species, accommodating themselves readily to the environment, assuming colors from climatic effect or different seasons and localities, or for purposes of protection—the form L. disippus being mimetic of plexippus, as already suggested by authors.

About one year ago I received a small bug from a gentleman in Maryland, together with the information that it was a serious enemy of the honey bee. It was stated that this bug would lie concealed among the flowers, and upon occasion would grasp a bee, and, holding it off at arm's length, would suck out its blood and life.
