The adult beetles are found feeding upon the elm leaves in 

 June, and the field notes for 1907 record them as mating on 

 June 14. On June 26 of the same year, one of the writers ob- 

 served their yellow eggs in rows along the midrib and other 

 veins of the elm leaves. The adult beetles feed upon the elm 

 leaves at this time and Fig. 94 shows the character of their 

 injury. 



But, as would be expected, the chief damage is done by the 

 larvae which skeletonize the leaves as shown in Fig. 95. So 

 abundant was this insect in 191 1 about Orono that the foliage 

 of some elms was very seriously damaged in this way, the in- 

 jury presenting identically the appearance of that caused by the 

 imported elm-leaf beetle. The larvae of this Haltica become 

 full fed late in July and descend to the ground for pupation 

 which takes place for the most part before August. This sea- 

 son larvae were bred in the insectary where the adult beetles 

 began to emerge August 15. A field excursion resulted in 

 the capture of adult beetles in the infested region August 23. 



The beetles collected at Orono in 1907 and 191 1 are burn- 

 ished copper with dark blue reflections or dark metallic blue 

 with bright coppery red reflections. They measure from a lit- 

 tle less to a little more than 4 mm. The collection of 1907 

 was determined by Mr. E. A. Schwarz as Haltica carinata 

 Germ. We have, as yet no Maine record of their appearance in 

 anything but Ulmus americana. Lots 29, 1393, 1403. 



The larvae resemble those of Galerucella hiteola in appear- 

 ance but differ in being a little smaller and paler, and in having 

 smaller tubercles, each of which is provided with but 2 or at 

 most 3 small setae instead of from 4 to 6 on each tubercle as is 

 possessed by the imported elm-leaf beetle larva. The larva of 

 H. carinata somewhat resembles that of H. ignita figured by 

 Chittenden in Bui. 23, N. ser. U. S. Div. Ent. 



Galerucella luteola. 



The imported elm leaf beetle was present in Fryeburg, Me., 

 this season and adults were captured in October in houses 

 where they had entered for hibernation as is their custom. Lot 

 1418.
