PERIODICAL CICADA 
Brood XIX of the periodical cicada ( Magic icada sentendecim tredecim 
Riley), the largest of the 13-year broods, appeared in great numbers through- 
out the greater part of its range. Two records from southeastern Kansas 
filled in a gap in the western limit of this brood. Three records from 
eastern Kentucky apparently extended the limits somewhat north of the 
previously known range. The interpretation of these, however, is confused 
by the problematical Brood VII of the 17-year race. Brood VII, a small 
compact brood in the Finger Lakes district of New York, was due to appear 
this year. There are a few scattered records of a single year's appearance 
" : o£ this brood in western Pennsylvania and southern West Virginia. The 
Finger Lakes records have been repeated over a period of 136 years, but, 
strange to say, no records were made this year, although the brood was re- 
ported from seven counties in 1915. The insect was reported from two 
counties in the south-central part of Pennsylvania. No previous records 
for this brood have been made from this part of the State; and the individuals 
were probably retarded or accelerated specimens of another brood, as are 
possibly those of the previous records of this brood beyond the western New 
York State area. This year brood XIX appeared in the following States and
