In addition to the above enemies several specimens of a new species of ichneumon fly were reared from the larva? at Tallulah. This species has been described by Mr. H. L. Viereck, of the Bureau of Entomology, as Hyperallus calirose} It is shown, much enlarged, in figure 25. Specunens of this parasite were reared from larvte which had been confined in the rearing cages for varying periods before entering the ground. The youngest larva, from which a parasite was reared, was removed from the tree on April 7, when it was about one-third grown, that is, 3 or 4 days from the egg. The parasite emerged 35 days later, on May 12. This period is, how- ever, rather longer than the aver- age, since this individual was de- veloping during the cold weather of April and May. All of the other specimens were reared from larvse which were nearly full grown at the time they were re- moved from the tree and placed in cages. From larvae placed in a cage on April 16, 2 parasites were reared on May 17, a period of 31 days. Fig. 25.—Hj^pcroZ/MscaHroas, a parasite of the peach 17 1 „ 1 1 • and plum slug. Much enlarged.

An adult of the host emerged on July 26, 15 days before the parasites appeared. From larvse taken on August 10, two parasites were reared on September 1, a period of 22 days. Three adult sawflies emerged on August 19, 13 days before the parasites. From larvie confined in a cage on August 12, one parasite was reared on September 3 (period, 22 days), one on September 4 (period, 23 days), and one on Septemb
