tofore understood was to live as a scavenger in the heads of the com- 

 mon Typha or cat-tail. The issuance as images as early in the spring 

 as April or May precludes the possibility of the larva:; of this gener- 

 ation feeding on the eggs of the bagworm, and clearly indicates that 

 there must be another host to carry it through the summer. That 

 the lan'te at this time are in some way associated with the Typha head 

 is likely, but whether they are there as scavengers or preying upon 

 some other insect whose habitat is the Tj^pha head is not apparent. 



In connection with the rearing of this moth it is interesting to note 

 that a small chalcid, Leucodesmia typica How., which is recorded by 

 Dr. Howard as a parasite of a small moth, Dakrumn coccidivora Com., 

 predaceous upon our larger scale insects (Insect Life, YII, p. ■102). 

 was also reared from the bags of the bagworm and is in all probability 

 a parasite of Dicymalomia pdianis. 



EGGS AND STAGES OF THE LESSER APPLE WORM 



(Enantw-ma prunivora Walsh)

During the summer of 1908 the writer had an opportunity of ob- 

 ser\'ing the eggs of Enarmonia prunivora Walsh, which had not been 

 previously kno\^^l to entomologists. This insect, as was shown by ]\Ir. 

 Quaintance in a paper upon "The Lesser Apple Worm" read before 

 the Association of Economic Entomologists at Chicago in 1907 and 

 published as Bulletin 68, Part V, from the Bureau of Entomology, 

 has been found frequently infesting the fruit of the apple and in 

 many cases its work has been mistaken for the damage done by the 

 codling moth. I find this condition to prevail in the orchards of Mis- 

 souri. 



In the paper cited the difference between the two species was plainly 

 pointed out, so that there should be very little confusion in distin- 

 guishing the smaller fusiform flesh-colored larva of the lesser apple 

 worm, with its brownish caudal comb-like structure, from the larva of 

 the codling moth. The work of the former was also shown to be dif- 

 ferent in several respects from that of the codling moth and of course 

 there could be no mistaking the two when the adult moths were com- 

 pared. Neither Walsh in Illinois, who first studied the insect in this 

 country in 1867 as the "plum-moth," nor Riley, who studied the in- 

 sect in Missouri in 1869, mention ever having seen the egg. Fletcher,
