d o (1 e r a c n c u m e r i s Harr.) are appearing on potato leaves, 

 and some insect is feeding quite generally on plantains, (very 

 probably D i b o 1 i a borealis Chev.) . Horn flies (Haeina - 

 t o b i a s e r r a t a Rob.-Desv.) are quite numerous on cattle. 

 An examination shows that eggs of the currant worm are abun- 

 dant. Elm foliage is full of holes, probably the work of larvae 

 of the elm flea beetle (Disonycha t r i a n g u 1 a r i s Say) . — 

 May 21. Terminal leaves of elms are badly twisted and wrinkled by 

 aphis attack, very probably S c h i z o n e u r a a m e r i c a n a 

 Riley. Potato beetles are very rarely seen, though many eggs 

 have been observed. The foliage of the few potatoes above 

 ground is badly eaten by the black flea beetle. Nests of the 

 applet ree tent caterpillar are very scarce and with but few 

 tenants. Currant aphis continues abundant. — June 3. Rose bee- 

 tles (Macrodactylus subspinosus Fabr. ) were ob- 

 served for the first time on rosebushes June 4, and considerable 

 damage has been inflicted. A species of plant louse (Chaito- 

 p h o r u s n e g u n cli n i s Thos.) has appeared somewhat abun- 

 dantly on the ash-leaf maple. Grasshoppers are becoming quite 

 abundant in old pastures. The scarcity of potato beetles is 

 cause for general comment, and the black flea beetles are ex- 

 ceedingly numerous on potato and tomato vines. — June 10. A 

 few full-grown forest tent caterpillar larvae (Malacoso m a 

 disstria Hiibn.) were observed. Spittle insects are uncom- 

 monly abundant on grass under a spreading shade tree. Rose 

 beetles (Macrodactylus subspinosus Fabr. ) are 

 abundant on applefrees, on thorn apple, and very numerous on 

 white dais}' and dock. The daisy flowers are eaten off in many 

 instances. — June 17. Potato beetle larvae were observed on one 

 plant June 22, and a few striped cucumber beetles (Diabro- 

 tica vittata Harr.) were noticed on lima beans. The cur- 

 rant aphis (M y z u s r i b i s Fabr.) is causing very little damage, 

 while tomato and potato vines are considerably injured by the 

 black flea beetle. — June 2 f i. Currant leaves appear as though 

 they had been eaten by the sawHy. though no larvae have been 

 observed. The little plant louse ( 1) r e p a n o s i p h u m aceri -
