4 INSECTS AFFECTING VEGETABLE AXD TRUCK CROPS. 
The record of injurious occurrences includes only Brooklyn. N. Y.. 
and Washington, D. C. Undoubtedly the species occurs in trouble- 
some numbers in many localities, but no records are available.

NOTES ON OCCURRENCE. 
ATTACK OX BEETS AXD CHARD. 
October 1. 1905. the writer first observed this species in a small 
colony on sugar beets growing in the insectary garden connected 
with the Bureau of Entomology. The insect was studied at that time 
with 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. 1912, after a lapse of seven years, this same species 
was 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, 
where the damage was practically complete. Injury, however, was 
complicated by another insect with which it was associated, the spin- 
ach or beet flea-beetle (Disonycha xanthomelmna Dalm.), which had 
been injurious to the same plants in an earlier and a later generation 
and was still at work throughout the time that the lepidopterou- 
larva was observed, and even later. The work of both species is illus- 
trated in Plates I and II. while Plate III shows, for comparison, a 
chard plant which has been slightly infested but not injured. The 
large holes were made chiefly by the beetles earlier in the season, and 
the blacker portions show where the larva? or caterpillars did their 
greatest damage. 
From the outset of attack it was noticed that larva? were rarely 
seen during the daytime and evidently were nocturnal or practically
