370 JNSECTS INJURIOUS TO THE CRANBERRY. 



The hind wings are dusky gray. The moths are very nu- 

 merous during the month of June, when eggs for a second 

 brood are deposited, the larvse from which appear early in 

 July, succeeded by the perfect insect, which deposits the eggs 

 that remain dormant until the following spring. 



Remedies. — For all cranberry insects flooding is the most 

 effectual remedy ; the vines should be kept under water for 

 two or three days, which will clear them for the time entirely 

 from all insect pests. Where this is not practicable, the vines 

 may be slwwered with a mixture of Paris-green and water, in 

 the proportion of a teaspoonful of the poison to two gallons 

 of water. Fires also may be lighted to attract and destroy 

 the moths. 



No. 228. — The Glistening Cranberry Moth. 



Teras oxycoccana (Packard). 



This moth, the larva of which is said to feed on cranberry- 

 vines, measures, when its wings are spread, nearly three- 

 fourths of an inch across. Its fore wings are of a uniform 

 reddish-brown color, with a peculiar shining appearance, the 

 red tint being due to scattered bright-red scales; there are 

 no other spots or markings. The hind wings are glistening

 of hairs at the tip of the abdomen. The caterpillar has not 

 been described. 



No. 229. — The Yellow Cranberry Worm. 



Teras vacciniivorana (Packard). 

 In the cranberry-fields of New Jersey this is a common 

 insect. The larva, which is shown magnified in Fig. 383, 

 both back and side views, draws the leaves together, fastens 

 them with silken threads, and feeds upon their upper surface. 

 It is of a pale-yellow color, with a slight greenish tinge, and 

 a few fine, long, pale hairs arising from prominent tubercles. 

 When mature, it is nearly three-tenths of an inch long. The 

 caterpillar changes to a brown chrysalis within the leafy en-
