Another trouble is that, as we learn from Dr. Ilagen of the Musenm of Com- parative Zoology at Cambridge, Mass., a certain parasitic fungus has been recently introduced into New-England from Europe, wiiich is mak- ing great havoc among the larvoe of this and other large moths belonging to the same group, just as another parasitic fungus has for many years back decimated the old-fashioned Silk- worms in Europe. The larva of the Polyphemus Moth is a large fleshy apple-green caterpillar as big as the thumb of a stout man. We have ourselves found it upon oaks and hickories, and it is said to occur sometimes on elm, basswood, ceutly dubbed the " American Silkworm," from the fact that Mr. Trouvelot, of Massachusetts, succeeded in rearing it in very large numbers, so as to obtain whole wagon-loads of its cocoons. The practical difficulty, however, with this, as with a closely allied species from Asia, the Ail- anthus Silkworm (A/lnc/ts t-ynlhi'a) is. that the butternut and thoru. It attains its full growth in August and September, and thereupon spins among the twigs of the tree which it inhabits a tough pod-like oval cocoon, enveloped in leaves and composed of a brownish white silk.
