as hatched make their way to the center of the bud and feed on petals 

 and stamens. Full grown larva is about one quarter of an inch in 

 length, cylindrical, tapering slightly posteriorly and anteriorly. 

 When young it is of a dull, brownish green color, gradually assuming 

 a reddish tint until at maturity the sides are of a deep dull pink 

 arranged in wavy shaded stripes, which are more intense on the sub- 

 dorsal spaces. Head oblique, round, pale glossy grayish brown 

 with the dark brown mandibles and the triangular face outlined 

 with the same color. Cervical collar entirely covering top of first 

 segment, of glossy dark grayish brown marked on dorsum with a 

 narrow but distinct longitudinal line of white. Anal plate brown 

 and horny. Legs and prolegs well developed. Pupates in dense, 

 tough yellowish cocoon on the surface of the ground. Moths issue 

 in about ten days. There are at least two distinct broods in a season, 

 the second of which hibernates in cocoons." 



We did not find this species in New Jersey and Mr. August Busck 

 suggests that it may not occur this far north. 



COLEOPTERA. 



Tyloderma foveolata Say. 



Of the insects associated with the evening primrose, the weevil 

 Tyloderma foveolata Say is one of the commonest and most widely 

 distributed. This species was described by Say in 1831 (Desc. N. 

 A. Cure, p. 19, Lee, ed. I, p. 284), since when its occurrence on the 

 evening primrose has been recorded at various times. Webster 

 briefly mentions (Ins. Life, Vol. 2, p. 11, 1890) the habits of the 

 insect especially in regard to oviposition while Girault (Ent. News, 

 Vol. XXII, p. 112, 191 1 ) gave a further and more detailed account 

 of the insect as he observed it in Illinois. The writers have had 

 it under observation in New Jersey for the past few years and the 

 account here given is a result of their observations as well as those 

 in the papers noted. 



The species is widely distributed in the eastern part of the coun- 

 try. Blatchley and Leng (Rhyn. N. E. Amer., 19 16) state that it 

 " ranges from New England to Nebraska and south to Florida." 

 Smith (Ins. N. J. St. Mus. Rept., 1909) reports it as occurring 

 throughout New Jersey, May, June, and in our observations wc have 

 found it to be more or less common wherever the primrose grows. 



It is said to breed in willow herb {Epilobium sp.) as well as the
