for the "brood failed to show up anywhere in our 1919 iurvey. This

Nebraska M a H„ Swenk (May 25): Relative to Brood XVI of the periodical 
cicada, I believe there is an error here* Although Nebraska never 
extended east of the Missouri River, or south of the 40th parallel, 
in 1857 it included much of the Dakotas, Montana, Wyoming, and 
northeastern Colorado; in fact it reached its present boundaries 
only in 1861. Some of the earlier reports use the name in a very 
broad sense, and in the fifties it was sometimes loosely used for 
localities row in Kansas, end it may "be this record of the periodi- 
cal cicada for Richardson County in 1857 really pertained to some 
locality farther south, Again it rray have .been a plain misidenti- 
fication At any rate, it was not found by us in 1908 nor do I 
have any records of it left me by Brof„- 3runer for the year 1891, 
My opinion- is that we have only Brood J.V, vhich I traced over 
a considerable area in southeastern Nebraska in 1913, and of which 
we have records of occurrence in Otoe County in 1896, 
GIPSY. MOTH (Po^h^tria disbar L. ) 
Massachusetts A« J, Bourne (May 26): Eripsy moths are present in such\3mall 
numbers that the crchardists are practically ignoring them, Mr, 
Earrar, of South Lincoln, finds but 20 egg masses on '-shout 
l t 200 young bearing trees 9 (J-yne 22): Mr, Lacroix states that 
while the gipsy moth can be found somewhat on a very few bogs, yet 
his observation would indicate that it is causing less and less ' 
damage each year. 
Rhode Island A E* Stene (June 20): Scouting for the gipsy moth indicates 
that this inject is rather more widely distributed than at coy 
time in the past and is quite a little more abundant than it / was 
last year although so far there has been little indication of . 
prospective defoliation in any of the sections in which We have 
worked,,
