been observed in this locality, but they are comparatively very 
rare. Currant worms [Pteron us ribesii] have appeared 
on currant bushes. The currant aphis [Myzus ribis] is not 
very abundant. May 21. Tent-caterpillars are comparatively 
scare thus far. A few forest tent-caterpillars were noticed in 
Poland 4 miles away. The appletree bark louse has also proved 
quite injurious to cultivated mountain ash and Crataegus in a 
yard. One orchard near a forest undergrowth is about equally 
infested with the appletree and forest tent-caterpillars. The cold 
seems to have kept the tent-caterpillars in check, but plant lice 
are very numerous and injurious. May 31. Colorado potato 
beetles [D or yphora 10-lineata] first appeared in con- 
siderable numbers May 26. Tent-caterpillars are relatively very 
scarce. The prolonged rainy weather seems to have kept some 
insecis in check severely, though currant worms are plentiful and 
quite injurious. June 6. Cabbage butterflies [Pieris rapae] 
were noticed June 13, and on the 18th rose beetles were quite 
abundant. The onion thrips [Thrips tabaci] is working on 
our lettuce. The first grubs of the Colorado potato beetle were 
seen June 13. Grasshoppers seem to be more plentiful than last 
year and currant worms are unusually abundant. Not a cocoon 
of either tent-caterpillar has been observed. June 19. Squash 
bugs were first observed on the vines June 16. Grasshoppers 
are very plentiful, but so far no particular injury has been done 
by them. Potato beetles are unusually numerous. Rose beetles 
[Macrodactylus subspinosus] are attacking the ap- 
pletrees and rapidly devouring the smallapples. June 27. Rose 
beetles have now disappeared, and it does not seem as if 
they had caused much injury. Grasshoppers are reported very 
numerous in the valleys but not on the hills. The spinach flea 
beetle [Disonycha collaris| has been quite abundant in 
this vicinity. July 13 two specimens of the praying mantis 
[Mantis religiosa] were observed in this place, undoubt- 
edly coming from the eggs sent me last spring, though I have 
been unable to find any young from their egg clusters. July 13.
