to injure seriously the raspberry crop. "It is mentioued by Dr. 

 Packard as iiaving been found by him on red maple leaves, and he 

 also mentions the sweet pepper bush {Clethra ahiifolia) as its food 

 plant, while Mr. Emerton observed it on the currant. [Prof. P'rench 

 has observed it near Carbondale feeding on Lepidium virf/inicum 

 and Polygonum avicidarc] As this species is not mentioned in any 

 of the numerous entomological reports or works on applied entomo- 

 logy [excepting by French], it has probably not heretofore been in- 

 jurious. The larva injures the crop by eating the leaves and ber- 

 ries, and the same articles of diet were taken by all the specimens 

 reared by me. I first noticed them during the middle of -Tune, at 

 which time they were about half grown. Those reared in confine- 

 ment made the cocoons July ath to 7th. the larva^ changing to 

 chrysalids two days later. 



*'The larva is of a beautiful reddish violet color, marked trans- 

 versely Avith reddish stripes, and 2^ to 3 inches long. On the third 

 thoracic ring is a sharp tubercle, 'while just behind the middle of 

 the body is a large wart, and also one on each side of the middle ; 

 just in front of the last pair of abdominal feet, on the back, is 

 quite a large hump. The larva is a handsome object, and when 

 once seen and identified, is easily recognized afterwards. The 

 cocoons were made of raspberry leaves and berries, in nearly circu- 

 lar arrangement, the whole mass held together with silk. The 

 cocoons were all formed on the floor of the breeding cages. In one 

 instance the larva crawled into a cocoon that had been made by 

 another species, and in due time emerged as a moth. The pupa 

 is three fourths of aninch long, Hesh-colored except the end of the 

 abdomen, which is reddish brown. On the back is a row of black 

 dots, one for each ring, and on the side are three rows, one continu- 

 ing to the head. The whole is sprinkled with reddish dots. The 

 venation of the wings and the antenna' were plainly to be seen. 



" The moths appeared July 24 and 25. They were quite variable in 

 color and markings, yet there was a close general resemblance. 

 Tsually of a fawn color, some were light ochreous and others dark 

 reddish brown. On the fore wings were usually found two chocolate 

 brown lines, the outer one making an acute angle near the apex, 

 and as a rule passing over the surface of the hind wings also, while 

 the inner line was more wavy and rarely passed on to the posterior 

 wings. Outside of the outer line were several darker shades, which, 

 in many specimens, were brown patches. Near the center of each 

 wing the discal dot was always present. 



"When the matter of remedies is to be considered, one is to be 

 sought for that will not only cjestroy the pest, but also leave the 

 fruit in an edible condition. The kerosene emulsion and arsenical 

 preparations were tried and found effectual for the destruction of 

 the insect, but Avhen applied while the fruit was yet on the plants 

 they of course rendered it unfit for use. When for any reason the 

 fruit is not to be gathered, or when the caterpillars appear after 

 the fruit has been harvested, the above preparations may be used 

 with benefit. The remedy found most useful was hand-picking or 

 beating the bushes with large broom-corn brushes, and then crushing 

 the larvae as they fall to the earth. As yet the time and place of
