 the greenhouses in this State ; very common on Coleus plants. Cacti, 

 Geranium, Ivy-Hedera, and also found in ants' nests. It is recorded 

 from Washington, D. C.; New Mexico, California, Florida, Colorado,

 This is another very common pest at Lawrence, Mass., in all green- 

 houses on palms and Coleus ; it is found in ants' nests at Lawrence ; at 

 Washington, D. C, and New Mexico on a house fern. It is quite safe 

 to say that the two last coccids cited can be found in nearly all of the 

 greenhouses in Mass., although we have no such record, and perhaps 

 in nearly every State if looked for.
