leaves where new blisters are started. The winter is passed as eggs 

 beneath the bud scales. The adult mite is white, elongate, 4-Iegged, 

 H25 inch long (Fig. 242). 



Control. — Spray with lime sulphur, wash before leaf buds open. 



In addition, the following Eriophyids occur in orchards: Epitri- 

 mertis pyri Nal. and Phyllocoptes schlechtendali Nal. on apple and 

 pear, Eriophyes phloeocoptes Nal. on plum, and Phyllocoptes cornutus 

 Banks on peach. 



Family Tarsonemid^ 



Cyclamen Mite {Tarsonemus pallidus). — This mite is reported from 

 many scattered sections as destructive to cyclamens. It destroys 

 the flowers and flower buds, and all 

 stages may be found there. Attacked 

 flowers become distorted, streaked and 

 flaccid and die prematurely. In many 

 cases they die before opening. Infested 

 leaves curl. 



The adult mite is pale brown, H25 

 inch long; the eggs are oval and trans- 

 lucent. 



Control. — Spray plants with nicotin 

 and soap solution when the younge 

 plants are transferred from flats to pots, 

 and every 10 days thereafter.

Class Diplopoda 



243. — a common milliped. 

 {After Folsom.) 



Millipeds. — Millipeds are often termed "thousand-legs," "galley- 

 worms," or "false wireworms." They sometimes occur in rich garden 

 soils containing much refuse organic matter, and do considerable 

 injury. They attack plants grown from seed, and also gnaw holes in 

 potatoes, strawberries and bulbs (Fig. 243). 



The eggs are laid in holes in the soil in the spring, and it requires 

 about 2 years for the young forms to reach maturity. They are' 

 night-feeders. The most common injurious forms belong to the 

 Families Julidce and PolydesmidcB. Julus canadensis is dark brown or 

 black above with sides spotted with yellow, and is from i to 2 inches
