PSYCHE. THE INSECTS OF BE TULA IN NORTH AMERICA. BV ANNA KATHERINA DIMMOCK. CAMBRIDGE, MASS. {Concluded from p 24J.) Amp/iidasYs cogirataria Guen^e (Hist. nat. d. ins., 1S57, ^-9' ^^I'sii. et phal., v. i, p. 208). Cramer (Bull. Brooklyn entom. see, Aug. 1SS3, ^'-^' P-4S) briefly describes the eggs of this species, of wliich about five hundred were deposited 3 June. Bowles (Can. entom., April 1S71, \'. 3. p. 1 1-12 ) (.Vnn. rept. Entoiii. soc. Ontario, 1S71, p. 3S-39) describes a vari-ety of the larva which fed on "black currant" {^Ribcs Pm'g-nim']. and Goodell (o/. c//., Ajiril 1S7S, V. 10, p. 67) describes another varietv which fed on apple and pear. Lintner (En-tom. contrib., no. 3, 1S74, p. 166) briefly de-scribes the larva, giving Acer as food-plant, and Packard (Guide study ins., 1869, p. 322; gives a few notes on the larva, which he states feeds upon Ribes aurcitm^ R. I'grossularia^ and Spiraea ftomentosa. Pilate (Papilio, May 1SS2, v. 2, p. 71) gives "honey-locust" {Glcdils.c]ita iriacaiithos^ as food-plant. Lintner (Entom. contrib. [no. i], 1869, p. 64) gives plum as food-plant. To the above food-plants may be added Betitla alba, B. Icfita, Castaiiea vesca. Salix, and Spiraea sorbifolia. The larva varies from pea-green to brovvnisli grey or even brownish black in general color: as far as noticed the green form is from Ribes, Salix and Spiraea, \\h\\& those from apple exhibit all the color varia-tions; on Betula and Castaiiea the larvae are grey. Similar variations have been noticed in the larvae of Anip/n'dasys betitlaria, a European species. The larvae often rest in a partially twisted position, with their rigid bodies at a considerable angle from the stem to which they cling, thus imitating very closely twigs and petioles. The larvae are common in New England in [nlv and August ; they pupate from the latter part of July to September, the pupa hibernating under leaves and rubbish. Cymatophora crepiiscularia Treits (Schmett. v. Europa, 1S27, v. 6, pt. i, p. 190). Goodell (Can. entom., Apr. 1S7S, V. 10, p. 67) has described the larva of this species from a single specimen taken on plum, 30 May; pupation took place 6 June, and the imago emerged 19 June. In Europe this very variable larva has often been reared. Herr (Anleitung d. schmett. u. raupen , . . 1S33, pt. 2, p. 272) gives a good description of the larva, and states that its food-plants are Aquilegia, Salix, Populus, Aliiiis, Ulmiis, Spartium, and Sambucns. Kaltenbach (Pflan-zenfeinde, 1872, p. 614-615) writes "A very common geometrid whose larva is very dif-ferently marked according to its food-plant. On Salix Borkhausen found it brownish-green, on Italian poplar grey-green, on Alnus brownish-grev, on Ulmus lighter green than on Salix, on Sambiicus grey-brown, etc. Treitschke's specimens reared on plum were yellowish. Pupation takes place under the ground; the moth appears in two genera-tions, in spring from hybernated pupae and again in July. The larvae appear in June and in September." Kaltenbach {op. cit., p. 1 10, 234, 302, and 435) adds the following to previously' mentioned food-plants : Betula alba. Genista, ^uercus, Rubus, Lonicera, and Ligustrum. The larva of this species is common on Betula alba in eastern Massa-chusetts, where it isYound ready for pupation as early as the middle of June. Of three larvae taken 12 Aug. 1SS2, one pupated 29 Aug. and hibernated as pupa, tieveloping an
