mostly in southern New Jersey, retaining only a few myself. Adults 
from these masses were seen during the summer of 1901 at a number 
of places, and during the following winter I added materially to the 
supply by further lots of eggs obtained through Mr. Laurent. In 
addition, Professor Shngerland sent me a number of egg cases of the 
European species, which had established itself, in northern New York, 
also the result of an accidental importation. There were thus in New 
Jersey during the early spring of 1902 a large number of eggs of 
Paratenodera sinensis Sauss., some of which had been placed there by 
insects that might be considered native to the State, since they were 
born and bred there; and an additional lot of eggs of Jlantis religiosa 
Linn., natives of New York State, and which might have been ex- 
pected to do fairly well in the somewhat milder climate into which 
they were introduced. Hatching was pretty general from all the 
ego masses of the Chinese species; but so far as I could make out 
none of the European egg cases produced young. 
During 1902 the adults were seen everywhere that the introduction 
had been made; but nowhere in any very large numbers. Still they 
were there, and again, during the early spring of 1903, I added some 
350 egg masses, secured from Mr. Laurent, to the previous sendings. 
The result in 1904 was not in proportion to the work that had been 
done. Fewer examples were seen in most of the places than ever 
before. In one locality only was any considerable number of speci- 
mens noticed. In one place that had received sendings each year, and 
which was almost a duplicate of the locality near Philadelphia where 
they had first established themselves, not a specimen could be found. 
T sent Mr. Dickerson through one of the places that he had seeded 
down, and where the location of every egg cluster had been mapped, 
and, while many of the whole clusters were found, the eggs apparently 
hatched, the net result seems to have been one new egg mass and 
nothing else. As the result of introductions continued three years in 
‘succession there is no one point where I could go at the present time 
with any reasonable hope of finding even a single egg mass. 
For some reason New Jersey seems to be a veritable paradise for 
the injurious species that are introduced; but something very much 
to the contrary for such beneficial insects, or rather predatory forms, 
as have been introduced to control them. So far as the records go, 
they offer very little encouragement to those who are inclined to de- 
pend upon fighting injurious species with natural enemies. 
Mr. Washburn asked whether any coccinellid was found working 
on Lecanium. 
Mr. Smith said no, but that Lecaniums were rare in New Jersey.
