field and this after careful search. He also states that they are solitary feeders 

 and that they leave their food plant during the day and hide. Jewett (loc. cit.) 

 states that there are from three to four broods a year, each one requiring from 

 37 to 39 days, the fall brood hibernating as pupae. 



Jewett (loc. cit.) describes the egg and Van Wagenen (loc. cit.) gives a 

 description of the larva, which was drawn up for him by Lintner. Edwards 

 (Papilio, vol. iii., pp. 145-8, 1883) under the name £. coUaris gives brief 

 descriptions of the larvae after each moult, beginning with the second. The 

 adult was described by Hubner in 1818 (Zutr. exot. Schmett., i. 7, f. 3, 4,). 

 Barnes and McDunnough in their Check List of Lep. of Bor. Amer., 1917, give 

 collaris Fitch and antica Wlk. as synonyms. 



Haemorrhagia diffinis Boisd. (Lep.) 



Under the generic name Hemaris, Edwards (Bui. 35. U. S. Nat. Mus.) 

 lists dogbane as a food plant of this species and gives several references to the 

 larva. Mead (Can. Ent., vol. ii., p. 157) gives a brief description of the larva 

 and lists snowberry as the food plant. Lintner (24th Rept. N. Y, St. Mus. 

 Nat. His., pp. 109-11, 1870) gives a description of the larva and cocoon and 

 states that the larva was taken on bush honeysuckle Dieiinlla trifida. We have 

 not noted this insect on dogbane in New Jersey, although Smith ( Ins. N. J., 

 p. 425) records it as not rare, larva on Apocynum and Symphoricarpus. 



Pyrausta futilalis Led. (Lep.) 



On several different occasions, the yellowish, black spotted larvae of this 

 species were abundant on dogbane, notably at New Brunswick, N.J., July 25, 

 Oct. 2, and Princeton Junction, N.J., July 28. They were found in colonies 

 webbing up the foliage and tips, feeding thereon and destroying everything except 

 the larger veins of some leaves. They hide by day in the curled up partly eaten 

 leaves and feed at dusk and during the night. At the approach of cool weather, 

 larvae under observation constructed rather loosely built cocoons within curled 

 and pulled-together partly eaten leaves. Dormant larvae were found in such 

 situations in November, and from this it appears that pupation may occur in 

 the spring. Most of the larvae under observation were parasitized. The adult 

 was described in 1863 by Lederer ( Wien. ent. Mon., vii., 467). Dyar in his Check 

 List (Bui. 52, U. S. Nat. Mus.) gives crccialis Grote as a synonym and the 

 distribution as the Atlantic States. 



A good account of this species by Dr. E. P. Felt is found in Lintner's 

 11th Report on the Injurious and Other Insects of the State of New York 

 (49th Rept. N. Y. St. Mus., 1896, pp 138-142). This paper includes notes on 

 the habits of the larvae, descriptions of the larval stages, number of generations, 

 etc., together with a bibliography of the literature up to 1896. 



Miscellaneous Species Found Associated With Dogbane. 

 Very little opportunity was afforded to collect the insect visitors and 

 the following list is recognized as woefully incomplete.
