Report of the State Entomologist. 49 



observed iu Albany the present year, 1887, but to a mucli less 

 extent than before. Early in June individual leaves of elm were 

 picked up from the sidewalks, having their foot-stalk so peculiarly 

 eaten to a point that it at once suggested the former demonstration 

 above mentioned, which had not been observed in the intervening- 

 years. The suspicion was confirmed a few days later (June lOtli) by 

 the falling of girdled tips in every respect like those of 1883. The 

 fall continued for some time thereafter — perhaps throughout the 

 remainder of the month, but as it was not very abundant, and was 

 only conspicuous in certain localities in the city — the most marked 

 one being in the vicinity of St. Peter's Church, at the intersection of 

 Maiden lane and Chapel street, — no particulars were noted of its 

 extent or continuance. The caterpillar is represented in figure 23. 



The Same Observed at Utica, N. Y. 

 In the first notice of this attack, above cited, it was stated that it 

 had also been observed by me at Troy, N. Y., at the time that it was 

 prevailing at Albany, but had not been reported elsewhere, although 

 it jjrobably extended to other localities where the Orgyia abounded 

 under similar climatic conditions. My only knowledge of its occur- 

 rence at other places, is from a communication made to the JJtica 

 Morning Herald, by Mr. Daniel Batchelor, of that city, in June of 

 1887. The cutting from the jDaper is before me, but its date was not 

 preserved. Mr. Batchelor states: 



Yesterday, L. B. Root, of New Hartford [six miles west of Utica], 

 informed me that the leaves of an elm tree on his lawn were falling 

 off in showers sufficiently to cover the ground immediateh' under the 

 tree. On riding into town, Mr. Boot had observed an elm on the 

 nox'th-ea3t corner of Genesee and Dakin streets, where the same green 

 shower of leaves was fluttering down. The writer went to the tree, 

 and there saw the fresh, green, glossy leaves fast falling and bestrew- 

 ing the street about as thickly as do the faded leaves in autumn. 

 The leaves are severed from the twigs about midway of the j)etioles 

 or stems, a few only being cut off nearer to the axils. The severing 

 is as clean as if done with a razor. Professor Lintner, the State 

 Entomologist, first witnessed the same kind of defoliation of elms in 

 Albany, early in June, about five years ago. 



Must the Insect be Renamed ? 

 It is possible that the above attack, together with all that I have 

 hitherto published of the i^resence and operations of 0. leucodirjma in 

 Albany, may have to be referred to another species. Mr. John B. 

 Smith, of the National Museum at Washington, who is conceded to be 

 excellent authority in the Lepidoptera, and has for a long time been 

 a careful student of the order, having lately seen examples of the
