A Japanese Bug New to New Jersey (Hemip.). 

 During the latter part of the summer of 1915 an outbreak of 

 "lace bugs" occurred on hardy azaleas growing in widely separated 

 parts of New Jersey, notably at Rutherford, Riverton, Arlington, 

 Palmyra and Far Hills. At some of these places the damage was 

 quite severe, much of the foliage being lest and the remainder 

 discoloured and brown. Through the courtesy of Dr. L. O. Howard, 

 the species was identified by Mr. Otto Heidemann as Stephanitis 

 azalea Horv., of the family Tingitidae. Mr. Heidemann also said 

 that this insect was first observed in the United States by Dr. 

 Chittenden several years ago at Washington, D. C, on azalea 

 plants from Holland, the bugs being imported there from Japan. 

 Most of the infested azaleas in New Jersey came originally direct 

 from Japan. For the past several years Azalea amcena var. Hino- 

 degiri hg.s been a favorite with New Jersey importers, and this was 

 the variety against which most of the bugs directed their attacks. 

 The species was described in 1912 by Dr. G. Horvath in the X 

 Annales Musei Nationalis Hungarisi.p. 333, Budapest, Austria.

A State's Insects and Their AcTnrriES. 



BY HARRY B. WEISS, NEW BRUNSWICK, N. J. 



According to Smith's Insects of New Jersey, and other papers 

 dealing with the insect fauna of that State, the number of species 

 listed trom New Jersey is about 10,530. Considering them collec- 

 tiveh% and in a general way, it is interesting to know what ihey are 

 doing. Are most of them injurious to vef;etation.'^ Are many bene- 

 ficial.^ and so on, are the questions v/hich naturally arise when so 

 many species are considered. Such inquiries can best be answered 

 by charting the actual proportions of each group engaged in differ- 

 ent lines of work. This has been done on the accompanying chart. 

 The large circle indicates what proportion of the total number of all 

 species found in New Jersey is occupied by each of the important 

 orders. The smaller circles indicate the predominating activities of 

 each ot the main groups, these activities being separated as: insects 

 injurious to vertebrates, those feeding upon or injurious to vegeta- 

 tion, predatory species, scavengers and parasites. It would be 

 possible, of course, to have a larger number of divisions, but many
