S6 EXPERDIEXT STATION. - [Jan. 



given to the apple trees of the State, and in general a eloser 

 examination of our cro])s, in order to protect them from injnrv, 

 is evident. 



Flies, fleas, roaches, bedbugs and other household pests liavc 

 required considerable correspondence during the year; and it 

 would seem that whenever anytliing unusual made its appear- 

 ance anywhere in the State in insect lines, it aroused sufficient 

 interest to lead to inquiries. 



During the latter part of September, 1011, an unusual 

 abundance of cotton-worm moths, AlalxDna anjillacca Ilbn., 

 was noted, and this was also the case almost everywhere through 

 the northern States. Another, but smaller, flight of these moths 

 took place this year, only a single s]~)ecimen being captured at 

 Amherst. As, so far as known, this insect feeds only on cotton, 

 its appearance so far from where it normally occurs is always 

 of interest. 



One brood of the seventeen-year locust or cicada. Cicada 

 septendecim L., due in 1911, has never been reported from 

 Massachusetts though abundant in northwestern Connecticut 

 and eastern ISTew York. During that year specimens were 

 captured in ISTew York only about three miles from the Massa- 

 chusetts State line. Under these circumstances it is probably 

 safe to consider this brood as also occurring in southwestern 

 ]\rassachusetts. though perhaps in limited numbers. 



The discovery in January, 1012, of more than 50 specimens 

 of a lady beetle, TlipporJaniid anihiffua Ixc, in bunches of 

 celery purchased in the market at Amherst, is of interest, as 

 the beetles are natives of the Pacific coast and the celery came 

 from California. Fortunately, these insects are beneficial, but 

 injurious forms could easily be introduced into Massachusetts 

 in similar ways and add to our already too long list of enemies 

 to fiirht here. 



The juniper scale, Diaspis rariieli Targ., a European foe of 

 the juniper and arbor vitfp, was found during the year in such 

 abundance on plants imported from abroad as to seriously in- 

 jure them. This insect has already been found in a number 

 of places in this country, probably in all cases having been 

 received from Europe. A serious attack on valuable hedges of
