THYSANOPTERA 701 



It is a Nearctic form and is recorded by Miss Beach from bean, blackberry, elm 

 and hop, by Pergande as having been found on many plants infested with red spider 

 (mite), on which it had repeatedly been observed to feed, and by Bruner as feedino- on 

 mites in fold of cottonwood leaf. 



From these records it will be seen that S. t-uiacnlatiis is an interesting insect, and 

 one of the very few thrips that have been observed to be predaceous in their habits.

 by him to Mr Dudley Moulton of the Californian State Commission of Horticulture,

Limothrips cerealium chiefly infests cereal crops and has a wide European range, 

 whilst Hinds records it (under the name avenae) from Pennsylvania as very abundant 

 on oats during the summer of 1S98. I have specimens collected by Mr Champion in 

 Central America, though not yet recorded, and believe that the species will most 

 probably be found wherever cereal crops are cultivated. I have also found it in 

 various grasses and recently recorded it from the flower of the bittersweet [So/aiiiim 

 dulcamara); from the sap of a felled pine tree, and in large numbers from the witches 

 broom, on birch'. There are two e.xamples of this cosmopolitan species in the collection 

 made by Dr Perkins.
