1909, June, Brookline, Mass.; adult, Charles W. Johnson (A). 



1910, April, Victoria, B. C. ; reared from Narcissus bulbs, E. A. Wal- 



lace (G). 



1910, October, Victoria, B. C. ; larvae abundant in greenhouse, C. G. 

 Hewitt (G). 



1910, December, first published record; Johnson, C. W. (A). 



1911, August 19, Saratoga Springs, N. Y., reared from Iris roots, E. P. 



Felt (B). 

 1914, May to July, Walnut Creek, Berkeley and Oakland, California; 



ten specimens on the wing, W. M. Davidson (C). 

 1916, Melrose Highlands, Mass.; adult, R. T. Webber (D). 

 1916, San Francisco Bay region, Calif.; adults, W. M. Davidson (E). 



1916, July 2$, Bar Harbor, Mt. Desert Island, Maine ; I took a num- 



ber of adults on the wing in one of the large nurseries. They 

 were flying about among low-growing ornamentals, feeding 

 from the blossoms. The nurserymen had no record of damage 

 by the larvae to their bulbs. 



1917, February 5, Montreal, Quebec; adult in greenhouse, J. I. Beaulne 



(G). 



To these records I can add the following: 

 1916, May 23, Eburne, B. C. ; adult, R. S. Sherman. 



In 1917 I received through the kindness of Mr. H. F. Dietz, 

 of the Federal Horticultural Board, a number of larvae of this 

 species which had been intercepted in Narcissus bulbs from 

 Holland in November. The larvae pupated in the laboratory 

 from February 12 to March i, and adults emerged from Feb- 

 ruary 28 to March 14. On this last date some of the speci- 

 mens were still larvae. 



The species is recorded to have two generations a year. Its 

 host plants include onion, Iris, shallot, Narcissus, hyacinth, and 

 Amaryllis. Its reported distribution in America ranges from 

 Maine to California and from Texas to British Columbia, 

 Ottawa and Quebec. I believe that this species, like its com- 

 panion in habit, Mcrodon cqncstrls. is thoroughly established 

 in widely separated regions of this continent ; that many other 

 records of its occurrence at intermediate points will be forth- 

 coming ; and that it constitutes a real and totally unappreciated 

 menace to the interests of horticulturists, florists and onion 

 farmers. It will be very surprising if we do not have a sud- 

 den and severe outbreak of one or both of these pests, when 

 they have become a little more thoroughly acclimated and have
