THE INSECT FAUNA OF NEW JERSEY GREEN- 

 HOUSES EXCLUSIVE OF THE COCCIDiE. 



By Harry B. Weiss,

While greenhouse insects are not strictly a part of the New Jersey 

 fauna, many of them are to all purposes firmly established in their 

 glass homes and constitute a force to be reckoned with by the grower 

 of indoor plants. The number of square feet under glass in New 

 Jersey is conservatively estimated at several millions and in this 

 somewhat tropical atmosphere, certain species breed more or less con- 

 tinually. The following list while dealing only with New Jersey 

 insects is representative of conditions in most greenhouses in north- 

 eastern United States. Forty-nine species are listed exclusively of the 

 Coccid?e which have been treated in a separate paper. This family 

 numbers thirty-two species all of which belong strictly to the green- 

 house fauna, being unable to maintain themselves out of doors in 

 New Jersey throughout the year. The list while aiming to be as 

 complete as possible does not include accidental visitors remaining 

 only for short periods of time or such insects as white grubs and wire- 

 worms accidently introduced in the soil and troublesome until they 

 have been worked out.
