breeding. On Aug. 30, 1897, but two of these beetles were alive and 

 active. Between November 15 and December 9, one of these two died, 

 but the remaining one is still bright and active at this date, Nov. 18, 1898, 

 and has therefore hved for over 26 months under close observation with 

 no better food than dry samp. The above record shows beyond doubt 

 that these beetles can maintain hfe for long periods of time under com- 

 paratively unfavorable conditions. 



Byturus unicolcr Say. The latter part of May Dr Peck, state bot- 

 anist, brought me several beetles belonging to this species, with the state- 

 ment that from one to five were to be found in many of the opening 

 buds of his raspberry plants where they were evidently feeding. This 

 insect does not appear to have been noticed in the state since Dr Fitch 

 gave a brief account of it in his 14th report for 1870, though Dr 

 Lintner records in his 8th report for 1891, its receipt from New 

 Haven, Ct., where it had been injuring leaves and buds of the 

 raspberry. 



Elaphidion villosum Fabr. Complaints of injuries by the oak or 



maple-tree pruner have come from several localities the present season. 



Serious injuries were reported to me from Lake George and also from 



Oakes, Ulster county, where its operations had been observed for 

 several years past. 



Galerucella luteola Midler, The prolificacy of the imported elm- 

 leaf beetle was brought very forcibly before me by certain studies made 

 in connection with the preparation of State museum bulletin 20. The 

 last day of May, I captured two beetles well distended with eggs and 

 determined to ascertain for myself the number they would produce. 

 One was confined in a small, corked vial, and the other in a jelly tumbler. 

 As might be expected, there was considerable difference in the number 

 of eggs deposited, the former producing 431 and the latter 623. A por- 

 tion of the discrepancy was probably due to disparity of conditions 

 and the remainder must be attributed to a variation in capacity. In order 

 to bring out certain points clearly, I have tabulated the record.
