4 INSECTS AFFECTING VEGETABLE AND TRUCK CROPS. 



The record of injurious occurrences includes only Brooklyn, X. Y., 

 and Washington, D. C. Undoubtedly the species occurs in trouble- 

 some nunil)ers in many localities, but no records are available.

NOTES ON OCCURRENCE. 

 ATTACK OX r.KErS AND CIl.VUI). 



October 1, 1005. the writer first observed this species in a small 

 colony on sugar beets growing in the insectary garden connected 

 Avith the Bureau of Entomology. The insect was studied at that time 

 Avith sufficient care to enable a drawing of the larva to be made, which 

 is presented herewith. The moth, however, was not reared because of 

 an accident which occurred to the rearing jar in the writer's absence. 



September 30. 1012, after a lapse of seven years, this same species 

 Avas again detected by the writer and readily recognized from the. 

 drawing previously made. It was first noticed and caused consider- 

 able injury on Swiss chard growing in the grounds of the Bureau of 

 Entomology. The infestation covered one-half of a row of chard. 

 Avhere the damage was practically complete. Injury, however, Avas 

 complicated by another insect Avitli Avhich it Avas associated, the spin- 

 ach or beet flea-beetle (Disorn/rha xanthomchvnd Dalm.), Avhich had 

 been injurious to the same jjlants in an earlier and a later generation 

 and Avas still at Avork throughout the time that the lcpido})terous 

 larva Avas obserA'ed, and CA-en later. The Avork of both species is illus- 

 trated in. Plates I and II, AA'hile Plate III shoAvs, for compari.son, a 

 cluird plant which has been slightly infested but not injured. The 

 large holes Avere made chiefly by the beetles earlier in the season, and 

 the blacker portions shoAv Avhere the larva^ or caterpillars did their 

 greatest damage. 



From the outset of attack it was noticed that larva? Avere rarely 

 seen during the daytime and evidently Avere nocturnal or practically
