These are all general feeders on foliage of woody plants. An undetermined 

 tineid from Cephalatithus is mentioned in Insect life, vol, 3, p. 18. These and 

 Robertson's list of visitors to the flowers, are the only records I have found. When 

 beginning my study I wrote Dr. L. O. Howard, asking him whether the records of 

 the Division of entomology of the Department of agriculture included other species, 

 and he kindly sent me the following list : — 



1. Harrisimemna trisignata (Walk.). 



2. Laverna cephalanthiella Chamb. 



3. Aphis cephalanthi Thomas. 



4. An undetermined cecidomyiid. 



In my own studies I have come upon only the first of Dr. Packard's list and 

 the third of Dr. Howard's. I will now give my own list, omitting all flower visitors 

 except such as are not included in Robertson's list, arranging them by orders first 

 with notes and observations, and concluding with a summary list according to 

 habits. 



Lepidoptera. I. Melano7ni7ia aiiricinctarimn Grote. Pupae of this species may 

 be found singly in pith cavities excavated in the broken ends of dead stems about 

 half an inch in diameter, during the entire winter and early spring. They are 

 fotmd also in cavities excavated in the bark of the thickest of the fallen stems, 

 generally a number near together, where conditions are favorable. The cavities in 

 the bark are short and tortuous, and are directed toward the surface at the end and 

 cut almost, but not quite through, by the larvae before pupating. The pith cavities 

 in standing stems have the appearance of excavations of the wasp Dahlbohmia, 

 (No. 7 post). Although this is perhaps the most abundant of the Lepidoptera 

 found on the button-bush, larvae were not observed. A good many heads of fruit 

 were found still hanging in winter, with holes bored through them transversely to 

 the seeds ; I did not find the borers. I thought they might perhaps be the larvae 

 of this species, but found no proof. From pupae collected for breeding, images 

 emerged in May. They were determined by Prof. C. H. Fernald. 



2. Acronycta oblinita (Smith & Abbot). This is a common leaf feeder. Its 

 larvae when newly hatched are ramblers, feeding here a little and there a little, but 

 when they are older they feed at the tips of the flowering shoots. They begin at 

 the top, eating the leaves off down to stubs of the petiole, thus consuming generally 

 two, sometimes three or four pairs of the opposite leaves, and then removing to 

 another shoot. When not feeding they are often to be found resting in seclusion 

 on the gray bark of the preceding year's growth. They are very frequently 

 parasitized, especially by the big red Rhogas rileyi (No. 8 post) \ and the parasi- 

 tized individuals settle upon the stems, first overspreading them with a thick mat of 

 silk, attach their feet, and then at their death there exudes in the thoracic region a
