The systematic part of the work inchides useful keys for identifying 

 famihes and species, each species being described with notes on its 

 Hfc-history. The total number of Orthoptera recorded from New 

 England is 132, but no less than 28 do not occur there naturally, 

 being introduced purposely, e.g., Mantis religiosa, L., or accidentally, 

 e.g., Forficula auric iilaria, L., several cockroaches including Pycnoscclits 

 surinamcnsis, L., and the European mole-cricket, Gryllotalpa 

 gyyllotalpa, L. The latter insect has been recorded from the island 

 of Nantucket, but it is not known whether it has become fully estab- 

 lished there. Another introduced Euroj^ean Gr^dlid is Gryllus 

 doiiiestictis, L., which is now fairly numerous in certain parts of New 

 England. Of Tettigoniids, Dicstrammcna marmorata, De Haan, 

 is recorded as injurious in greenhouses, while three native species 

 of Scudderia — S. texensis, Sauss. & Pict., 5. curvicauda, De G., and 

 S.fttrcata, Br. W. — are possibly injurious when occurring in the vicinity 

 of cranberry bogs. Nemobius fasciatus, De G., though not usually 

 considered an injurious cricket, is undoubtedly responsible for a very 

 considerable diminution of food in New England pastures. Five species 

 of tree-crickets are abundant and somewhat injurious, though the 

 damage they do is perhaps offset to a considerable degree by the fact 

 that they destroy Aphids. The snow}' tree-cricket {Oecanthns niveits, 

 De G.) is the one most often recorded in economic literature as a pest, 

 but many such records apply to other species. It is of economic 

 importance chiefly in neglected orchards, where its punctures during 

 oviposition scar and injure the twigs and provide an entrance for 

 canker and blight. The narrow-winged tree-cricket (0. angnstipennis. 

 Fitch) is a common insect in apple orchards, but is recorded also on 

 oaks, alders, etc. The dusky tree-cricket {0. nigriconiis, Wlk.) 

 frequents raspberry and blackberry canes and sometimes injures them 

 severely in ovipositing ; it also oviposits in many other plants. The 

 four-spotted tree-cricket (0. qtiadripundatus, Beut.) is the most 

 abundant and generally distributed species. It oviposits chiefly in 

 such weeds as golden rod, wild carrot, aster, etc. The pine tree- 

 cricket {0. pini, Beut.) is described as being found only in pine trees ; 

 it oviposts in the pith and wood of the smaller twigs of the pitch 

 pine. 



The grasshopper of chief economic importance in New England is 

 Camnula pcllucida, Scudd. ; it is extremely common throughout the 

 northern part of the country and needs but a few favourable dry years to 

 enable it to multiply in such numbers as to render it a formidable pest. 

 Of the genus Melanoplus, twelve species are recorded, the commonest 

 being M. feniur-ntbrmn, De G., which covers the entire country and is 

 likely to occur in any grassy area or sedge from seashore to mountain 

 top. The destruction caused from time to time in New England by 

 grasshoppers is generally ascribed to this species, though M. mexicanits 

 aflantis, Riley, is also very abundant and injurious. Less often, 

 -1/. bivittatus. Say, becomes destructive locally.

Hvlobius pales, Hbst., although a voracious feeder upon the bark 

 of coniferous seedlings, escaped notice as an economic forest pest 

 until 1914. It is a native of the United States and apparently 

 occurs nowhere else except in Canada. Though white pine [Pimis
