THE CANADIAN ENTOMOLOGIST. 219 



Scolytus rugtdosus is common in the experiment orchard and very injuri- 

 ous, but does not attack healthy trees. Only such as have been injured 

 in some way seem to be infested. 



Ltimbriais, sp. Quite young worms have been sent from the celery 

 gardens of Northern Indiana, with the complaint that they injured th^; 

 young plants, first in the hot beds, and, later, in the field after trans- 

 planting. The injury has been of quite a serious nature. The Buffalo 

 tree-hopper, Ceresa bubaltis, was sent from Richmond, Indiana, June 1 2, 

 with the statement that they were destroying young tomato plants in 

 gardens. The three specimens received were yet in the larval stage, and 

 were at once placed on young plants in breeding cage. They attacked 

 the plants just above the surface of the ground, puncturing the stems, 

 causing a contraction and weakening of the stem, which soon fell over, 

 though the upper portion did not wither or at once die. The affected 

 part formed a distinct contraction, which was probably an eighth or an 

 inch in length, and discoloured. Precisely similar attacks were made on 

 'a species of Tasmanian Oxalis, which stood upon the same table with the 

 tomato plants, when the tree-hoppers were allowed to gather upon the 

 stems. The last of the depredators finished the pupal stage on July 8. 



The following species have been observed attacking the blackberry: — 

 Coleophora, sp. The larvae were observed eating into the tender expand- 

 ing buds in i\.pril, and in May they were observed mining the leaves. No 

 adults were reared, though attempts were made to do so ; Blennocampa 

 paupera was observed ovipositing in the young buds in April ; Anomala 

 bifiotata, adults were surprised in the act of depredating on the foliage 

 early in May, and an allied beetle, Trichius piger, was observed feeding 

 upon the blossoms in June. The larva of Eccopsis permu?idaria was 

 found eating into the fruit in May, the pupal stage lasting twelve days, 

 and the adult emerging May 21. 



The clover hay worm, Asopia cosialis, was found in abundance in 

 northern Ohio, April 27. Pupation was observed among these May 25 ; 

 adults emerged June 12. These last oviposited June 13-17, and ap- 

 parently these larvae were found in heads of living clover in breeding cage 

 July I St. Adults made their appearance on August 8, at which time 

 pupae and also half-grown larvs were to be found in the cages. 



Sandalus petrophya^ male and female, were observed at La Fayette, 

 Indiana, on red or swamp maple, Acer riibrum.
