THYSANOPTERA 



Thrypidae 



iritici Fitch, Euthrips 



Nymphs and adults of Euthrips tritici are very common in flowers and 

 flower buds of native hawthorns in April and May. Many flower buds 

 fail to open, and inside of them are found from one to a dozen or more of 

 these thrips. They were exceedingly abundant in the Cornell University 

 arboretum in 1918, and very few hawthorns there bore. fruit that year. 



COLEOPTERA 



Elateridae 



dubitans Lee., Limonius 



The beetles of the species Limonius dubitans occasionally are found 

 eating leaves of native hawthorns in late May and early June. On May 

 31, 1919, one of these click beetles was found on a Crataegus pruinosa 

 leaf where it had been feeding, and was attacked by an adult pentatomid, 

 Apeteticus madestus Dallas. The latter had its beak inserted into the 

 beetle, which died while being carried to the laboratory. 



pubescens Melsh., Agriotes 



The beetles of Agriotes pubescens were eating the leaves of Crataegus 

 punctata on May 23. The species is not common. 



Melanotus sp. 



The beetles of Melanotus sp. were eating the leaves of Crataegus punclata 

 on June 6 and June 8. The species is not common. 



Buprestidae 



aerosus Melsh., Brachys 



The beetles of Brachys aerosus were found feeding on Crataegus punctata 

 leaves in warm sunlight from May 30 to June 20. There were commonly 

 two or three to a leaf, feeding on the upper surface and cutting small 

 holes through the leaf. As many as fifty of the beetles were found on one 

 tree, while neighboring trees had none. They are from 4 to 5 millimeters 

 long, and are brown and gold in color. 



Scarabaeidae 



elongata Fabr . , Dichelonycha 



The beetles of Dichelonycha elongata were found feeding on Crataegus 

 punctata foliage, six being seen on one tree on May 31. A seventh beetle 

 was killed by three adult pentatomids of the species Apsteticus modestus, 

 which were feeding on its body.
