THE WESTERN CURRANT AND GOOSE¬ 
BERRY SPAN-WORM. 
(Thamnonoma 4-linearict Pack., and T. flavicaria 
Pack.) 
On the first of June, last year, Mr. Brose, fore¬ 
man of the Horticultural Department, called my 
attention to the condition of the gooseberry bushes, 
some of which were entirely stripped of their leaves 
by a worm that was then leaving them and going 
in search of other food. These worms when fully 
grown were an inch in length, were light-colored, 
covered with small black spots, and traveled by 
looping their bodies, and are one of the so-called 
“ measuring worms.'’ Their appearance was so like 
the old currant span-worm that I did not think of 
their being anything else until specimens of the 
moths sent to Mr. G. D. ITulst, Brooklyn, N. Y., 
were determined for me as Thamnonoma 4-linearia 
(Fig 10, a, b, c. ch, and T. flavicaria (Fig. 10, e, f, g.) 
A large number of these moths were reared in 
our breeding cages and the two species appeared 
in about equal abundance.
