18 Blattidae 



A total of 136 species are recorded in this list, whereas Morse records 

 126 for New England, including 8 species of adventive cockroaches found 

 but rarely. On the other hand, New Jersey, adjoining New York on the 

 south, has an orthopterous fauna of about 150 species. 



Taken together, Staten Island and Long Island have 112 species, and 

 24 species are recorded as not occurring on these islands. These species 

 are usually of more northern range. A collector will discover that some 

 of the species mature earlier on Staten Island than on the eastern part of 

 Long Island. 



The sequence of the families follows closely that of Morse's Manual of 

 the Orthoptcra of New England (1920), which is nearly that of West- 

 wood (1839). In Morse's book, or in the very useful Orthoptera of 

 Northeastern America, by Dr. W. S. Blatchley (1920), which covers a 

 much wider area, the species here mentioned are all treated in detail, 

 excepting three which have been recently described. Dr. Blatchley's book, 

 moreover, contains a useful bibliography of the writings of Scudder, Rehn 

 and Hebard, Caudell, and other authors who have mentioned the 

 Orthoptera of the State of New York.

BlattellA Caudell 



B. germanica L. Croton Bug. The adult of this common introduced household 

 insect is most common in early summer, but in warm kitchens and among warm 

 w^ater pipes it may be found at almost any season. It is generally distributed 

 in such situations throughout the State. 



Parcoblatta Hebard^ 



P. virginica Brunner (borealis Brunner). Ardsley-on- Hudson, Je, Winters; West

 The females are much longer-lived than the males.

3 In The Blattidae of North America, Hebard records Eurycotis caraibea (Bol.), Leucophaea 

 maderae (Fab.), and Blaberus discoidalis Serv., as adventive species found within the limits of 

 the State, and Professor Morse mentions still others as having been introduced into New England. 

 None of these insects, however, are likely to become established.
