184 FORTY-THIRB REPORT ON THE StATE MuSEmT. [88] 



The Insects of the Clover Plant. [Read before llie New York State 

 Apfricultural Society, at its annual meeting, January 19, 1881.] 

 (Fortieth Annual Report of the New York State Agricultural 

 Society, for the year 1880, pp. 10-26, figs. 1-6. 1881. Separate, 

 with t. p. cover, pp. 17, figs. 6 [October] 1881.) Republished in 

 [Transactions of the New York State Agricultural Society, for 1877- 

 1882, xxxiii, pp. 187-207. 1884] 



Eemarks on the value of the clover plant as a fertilizer, and on the 

 increase of insect depredations on clover. Lists of European clover 

 insect depredators, and of those known in this country are given. Of 

 the latter a few are noticed in detail and illustrations given, viz. : the 

 clover-root borer, Languria Mozardi Latr. ; the clover-seed midge, 

 Cecidomyia leguminicola Lintn. ; ' the clover-leaf midge Cecidomyia 

 trifolii Loew ; and the clover Oscinis, Oscinis trifolii Burgess. 



On the Life Duration of the Heterocera (Moths). [Read before the 

 American Association for the Advancement of Science, at its Cin- 

 cinnati meeting, August, 1881.] (Canadian Entomologist, for 

 November, 1881, xiii, j). 218-220.) Republished in [First Annual 

 Report on the Insects of New York, 1882, pp. 339-341. J 



But little attention has been given to the subject, as it is difficult of 

 investigation. The Noctuidce especially have been little observed. The 

 Attacince of the Bomhycidoe have brief lives — the Sphingldce somewhat 

 longer. In the Noctuidce it varies much. In Xylina, Homoptera, and 

 Catocala, it may reach two months, and through hibernation, six 

 additional months. The approximate life duration of the Noetuid 

 moths is probably about three weeks. 



The Corn Beetle. (Country Gentleman, for November 3, 1881, xlvi, p. 

 711, c. 1, 2—18 cm.) 



A beetle feeding on corn just from the field, in Acton, Mass., is iden- 

 tical with the species determined [by Dr. LeConte] as Lathi-ldius 

 pulicarius [see page 183], but possibly an error has occurred in the 

 determination. The injuries to the corn sent can not be due wholly to 

 the insect, which appears not to attack whole kernels, but only such as 

 had been previously broken. 



The Cabbage Plusia — Plusia Brassicse Riley. (Country Oentleman, 

 for November 3, 1881, xlvi, p. 711, c, 2, 3—41 cm.) 



The insect, in different stages, is received from Dover, N. J., where the 

 larvae are reported as destructive to cabbage and Swede turnips, and the 

 moths as ovipositing soon after sunset. The larva, pupa, and moth are 

 described, with mention of the larval food-plants, injuries from the insect 

 in the Southern States, its recent multiplication for the first in New 

 York, its resemblance to Plusia ni, of Europe, and its two annual broods. 

 As remedies, hand-picking, hot water and pyrethrum in powder or water 

 are recommended. The bibliography of the species is given.
