the discoloration and generally withered and unhealthy 

 look of the foliage. The treatment directed against 

 this insect in greenhouses is to spray it with a heavy 

 stream of water from the hose, thus dislodging it from 

 the plants. Doubtless the same method of treatment 

 would prove practicable if the spider became very trou-

Bumble Flower-beetle. — Goff reports this insect 

 {Euphoria indd) as sometimes damaging plums in Wis- 

 consin. It is a large, yellowish-brown beetle with the

 to speak of them. They sometimes do great damage 

 in the nursery by eating young budding stock, or by 

 digging and eating plum seeds which are sown ,in the 

 fall for growing stocks. Their customary wickedness,
