76 THE CHINCH BUG. 
for a considerable period of time, thus indicating a seashore habit 
on the one side, while the total lack of the short-winged form else- 
where indicated otherwise. ; . 
In a paper presented before the Entomological Society of Wash- 
ington,* “On the insects found on Uniola paniculata in southeastern 
Florida,” by Mr. EK. A. Schwarz, the author stated that Blissus leu- 
copterus occurred in large numbers on the upper part of the plant, 
the imagos and larger young among the ears and the smaller indi- 
viduals between the upper blades. Mr. Schwarz attributes this habit 
to the tough woody nature of the storm-beaten plant nearer the 
ground, thereby driving the insects to the more tender though more 
exposed portion of the plant. In connection with this statement the 
writer tells us that the imsect occurs in that southern latitude only 
in the short-winged form, and that in the examination of thousands 
of specimens from that region he had never found a single long- 
winged specimen. Under date of May 4, 1896, Mr. W. H. Harring- 
ton wrote of this species as follows: “ In September, 1890, I found 
it at Aulac, almost on the border between New Brunswick and 
Nova Scotia. It seemed not uncommon and occurred under stones, 
about the roots of grass, in a pasture adjoining the marsh where I 
found Diabrotica longicornis, the pasture being on the upland 
skirting the marsh. Both the long and short winged condition 
occurred, asin Cape Breton.” Dr. A. S. Packard communicated 
to Dr. J. A. Lintner the following extract from his diary: “ June 17, 
1871, at Salem, Mass., chinch bugs with wing covers extending over 
the basal third of the abdomen, seen in copula, end to end.¢ In the 
serious outbreak of this insect in the timothy meadows of northern 
New York, in 1882 and 1883, about 20 per cent of the bugs were of 
this short-winged form.” ¢ 
Although Dr. Asa Fitch, as early as 1855, refers to this form along 
with nine others, he does not give the source from which he obtained 
specimens, but just previous to this he says (p. 287) that he had met 
with but three specimens from his own State, and these were found 
on willow in the spring of 1847.° Had any of these been of the short- 
winged form he would have been very hkely to have mentioned the 
fact. Mr. EK. P. Van Duzee? states that he had known of the occur- 
rence of the species in western New York as early as 1874, and had 
also found it at Ridgeway and Muskoka, Ontario. Ordinarily the 
short-winged form predominates, but in hot, dry summers the chinch
