mostly in southern New eTersey, 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 Slingerland 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 1002 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 Mantis vdigiosa 

 Linn., natives of New Yorlv State, and which might have been ex- 

 j)ected to do fairly well in the somewhat milder climate into which 

 they were introduced. Hatching was pretty general from all the 

 egg 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 Avere seen everywhere that the introduction 

 had been made; but nowhere in any A^ery large numbers. Still they 

 Avere 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 1901 Avas not in proportion to the work that had been 

 done. FcAver exan'iples Avere seen in most of the places than ever 

 l^efore. In one locality only Avas any considerable number of speci- 

 mens noticed. In one place that had received sendings each year, and 

 Avhich Avas almost a duplicate of the locality near Philadelphia Avliere 

 they had first established themselves, not a specimen could be found. 

 I sent Mr. Dickerson through one of the places that he had seeded 

 doAvn, and Avhere the location of CA^ery egg cluster had been mapped, 

 and, Avhile many of the Avliole clusters Avere found, the eggs apparently 

 hatched, the net result seems to have been one ucav egg mass and 

 nothing else. As the result of introductions continued three years in 

 succession there is no one ])oint Avhere I could go at the present time 

 Avith any reasonable hope of finding even a single egg mass. 



For some reason New Jerse}^ seems to l)e a A^eritable paradise for 

 the injurious species that are introduced; but something A'ery 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 A^ery little encouragement to those Avho are inclined to de- 

 pend upon fighting injurious species Avith natural enemies. 



Mr. Washburn asked Avhether any coccinellid Avas found Avorking 

 on Lecanium. 



]Mr. Smith said no, but that Lecaniums Avere rare in Ncav Jersey.
