few Hessian flies are to be found in the " flaxseed " stage, though 

 • no complaints of their work have been received. A leaf miner, 

 probably Pegoinyia vicina Lintn., is very abundant in a 

 large field of beets. Spittle insects are quite common in certain 

 fields of grass. Potato beetle eggs are hatching, but the grubs do 

 not appear to be as numerous as the old ones and are 

 causing comparatively little damage. Black flea beetles 

 ( C r e p i d o d e r a cucumeris Harr.) have caused some in- 

 jury to both tomato and potato vines. Striped cucumber beetles 

 (Diabrotica vittata Fabr.) are present on pumpkin 

 vines but are not causing much injury. No squash bugs 

 (Anasa tristis DeGeer) have been observed this year, 

 though they are usually very abundant and destructive in this 

 section. Rose beetles (Macrodactylus subspinosus 

 Fabr.) are quite destructive to rose bushes, though late in appear- 

 ing, and leaf hoppers have also caused some injury to rose bushes. 

 Peas are more free from weevils (Bruchus pisorum Linn.) 

 than usual, but the vines are being eaten by a green worm similar 

 to the cabbage worm. House flies are not as abundant as 

 usual. — June 29 



Orange county [J. M. Dolph, Port Jervis] — A few mourning 

 cloaks (Euvanessa antiopa Linn.) and some Colias butter- 

 flies have appeared. Many small bees are frequenting plum 

 blossoms. — April 23. Plant lice (Aphis mali Fabr. and 

 Myzus c e r a s i Fabr.) are very numerous, specially on apple 

 and cherry trees and rose bushes. Tomato plants are also affected 

 by a species of plantlouse which may be Rhopalosiphuin 

 s o 1 a n i Thos. In general there are fewer insects than usual, 

 due probably +o the exceedingly dry weather. — June 2. Potato 

 beetles (Doryphora 10-lineata Say) have made their 

 appearance in considerable numbers, the first abroad on May 20, 

 and the first larvae being observed June 9. Hundreds of lady- 

 beetles were found on a crimson rambler rose, three or four on a 

 leaf. We have never seen them in such great numbers before. 

 This bush had been badly infested by plant lice, and the lady 

 beetles were undoubtedly attracted by their prey. The currant
