February, '16] WEISS: recently established pests ' 213 



ing as it does on the experience, ability and carefulness of the inspector 

 and the impossibility of closely examining every individual plant. 



Lepidoptera 



Gracilaria zachrysa Meyrick has been found in greenhouses in north- 

 ern New Jersey, the larvte of which turn over the tips and edges of 

 azalea leaves and feed therein, causing them to turn black and die. 

 This species has also been taken in the larval and pupal stages on 

 azaleas imported from Belgium and was evidently introduced from 

 that country. Evetria huoUana Shiff., which is the well-known, 

 destructive European pine-shoot moth on whose account the further 

 importation of pines from Europe has been prohibited, is also estab- 

 lished in New Jersey. 



Orthoptera 



In this order we have Gryllotalpa gryllotalpa L., the European mole 

 cricket to which numerous European writings refer as a troublesome 

 pest. The party on whose premises it was discovered claims to have 

 destroyed at least 20,000 including eggs. This insect undoubtedly 

 came over in the soil around plants from Holland or Belgium or both 

 of these countries and the impossibility of thoroughly inspecting soil 

 in such conditions is self evident. 



COLEOPTERA 



In this group we have Otiorhynchus sulcatus Fab., long established 

 in this country, suddenly becoming quite active as a rhododendron pest 

 in several parts of the state. Agrilus viridis L. var. Jagi Ratz., which 

 does considerable damage to standard and Rugosa roses, is another 

 foreign beetle which is prevalent in New Jersey. Still another and 

 much more injurious beetle, especially to Scotch fir, is Myelophilus 

 piniperda L., which as far as is known has only a slight foothold in 

 the state. Plagiodera versicolora Laicharting, which is an old name 

 for the common P. armoricce of Europe, was found during the last 

 two summers injuring poplars and willows at Arlington, Elizabeth and 

 Irvington. Both the larval and adult stages feed on the foliage and 

 do considerable damage. This species is jSrmly established in New 

 Jersey. 



DiPTERA 



This order is represented by Phytomyza aquifolii Gour., lately 

 found mining the leaves of English holly and also taken on holly 

 imported from Europe (Holland), by Merodon equestris L., known as 

 the narcissus fly, which was evidently introduced in bulbs from Hol- 

 land where it does considerable damage, and by Monarthropalpus
