plants as asparagus, beans. cabl)agre. and a variety of other garden 

 plants. From the above statements, it is evident that Mamestra 

 Icgitima is somewhat of a general feeder l)ut not a species one is 

 likely to find commonly associated with milkweeds. 



Euchaetias egle Drury (Lep.). 



The tufted larva; of this species occur on milkweed in various 

 sections of Xew Jersey but during the .sea.son of 1920 they were 

 not at all numerous. There are two broods in New Jersey, the moths 

 appearing in June and again in late July and August. Various 

 species of Asdcpias are recorded as food plants, chief among these 

 being A. conntti. Jewett (Can. Ent., Vol. XII, p. 230, 1880) describes 

 the eggs and first stage larva and states that his notes carry the 

 life history of the insect to the point where Lintner begins. Lintner 

 (24th Kept. X. Y. St. Mus. Nat. His., pp. 136-137, 1870) describes 

 the larvae after each moult and the cocoon. Edwards (Papilio. Vol. 

 Ill, p. 147, 1883) also describes the larva in addition to the adults 

 of the spring and fall broods. The adult was described by Drury in 

 1773 (111. Exot. Ent., ii. pi. 20, f. 3) and its distribution is given by 

 Dyar (Bull. 52. U. .S. Xat. Mus.) as the Atlantic States. 



Ammalo tenera Ilubner (Lep.). 



This is one of the common tiger moths of the Atlantic States and 

 has been recorded by various authors as feeding on Asclcpias. 

 Its i)referred food plant however appears to be Apocynum. Numer- 

 ous references to the early stages are given by Edwards (Bull. 35, 

 U. S. Nat. Mus.) under the name Ruchcctcs collaris Fitch and need 

 not be gone into here. 



Pygarctia eglenensis Clem. (Lep.). 



Edwards (I'apilio, Vol. Ill, p. 147. 1883) under the generic name 

 Jiuchcrtcs describes tlie larv?e and adults of the fall and spring broods 

 of this species and gives Asclcpias spp., especially A. tubcrosa, as 

 food plants. The adult was described by Clemens (Proc. Acad. Nat. 

 .Sci. Phil., XII, 533, i860) and its distributon is given by Dyar (loc. 

 lit.) as South Atlantic States. It is recorded in "Insects of Florida*' 

 ( Bull. .\mer. Mus. Nat. His., Vol. XXXVIII. Art. i. pp. 1-147. 1917. 

 IV Lep.) with the statement, "extends through the .Atlantic States to 

 Xew ^'ork."
