Blattidae 19 



male on Pyrus bush, feeding at night on honeydew of aphids, Jl 14, one male; 

 Riverhead, Jl ; Orient, Je ; Gardiners I., Je. 



The nymphs of this and other Parcoblattae pass the winter under dead leaves 

 and litter in the woods, and mature the following spring. 



P. caudelli Hebard.^ LI: Selden, Aug 31, six females; Yaphank, Jl-Sep, Jl, females 

 with ootheca, Jl 8, six males ; Wading R., Je 27 and 28, males on Pyrus bush 

 feeding on honeydew of aphids. 



P. pennsylvanica DeG. Bronx Pk., NYC; West Pt., Je ; Hudson, Morse (Rehn 

 & Hebard) ; Ithaca, May-Jl (CU) ; Portageville, Je; Conesus Lake, Je ; Lewis- 

 ton, Jl, Wat ; Rochester, Deveson ; Thousand Isls., two males ; SI : adults, 

 under loose bark, etc., Je-Aug. 



The males are especially active and are often hard to capture. 



Blatta Linnaeus 



B. orientalis L. Generally distributed over the State. While in very warm houses this 

 introduced species may be found at any time of year, in the average dwelling, 

 which is cool in winter, it has decided seasons, and mature individuals are 

 most common in the late spring and in summer. Hebard states that as its 

 appearance is coincident with the arrival of the shad in the Delaware River, it 

 is locally known as the " shad roach." While the females cannot fly, they are 

 excellent runners, and on SI are sometimes found under stones, etc., far 

 from any dwellings. None, however, appear to survive the winter as far 

 north as NY State, unless they are protected artificially by man. 



Periplaneta Burmeister 



P, americana L. As far north as NY this American species requires even more 

 protection in order to survive the winter than does Blatta orientalis, and for 

 that reason it is found in but few detached dwellings. In greenhouses, hotels, 

 and any large buildings that are kept warm, it finds more congenial surround- 

 ings and multiplies accordingly. It is very common in the reptile house, Bronx 

 Pk., where it "is trapped as living food for lizards, etc. As it is found on ship- 

 board, it also gets into the sea, and so occasionally is washed ashore on SI 

 and LI. Rochester, Deveson, is the most northern record for the State. 



P. australasiae Fab. A nymph of this introduced species was found in the green- 

 house, Prospect Pk., Brooklyn, Jan. 5, 1907, and no doubt it occurs in many 

 such places. It is very common in parts of the Southern States. Ithaca, Aug 

 24, 1894, a female with its egg capsule (CU). 



Pycnocelus Scudder 



P. surinamensis L. This species is very common in parts of the Southern States 

 and has been introduced in the reptile house, Bronx Pk. It is reported also 

 from several localities in New England. The many N. A. specimens thus far 

 found have been females, with the exception of a single male collected in the 

 reptile house, Jan 12, 1914. 



^ The compiler has discovered that the females of caudelli, contrary to the description of the 

 species, have short tegmina, and closely resemble the same sex in fulvescens Sauss. & Zehnt. ; so 

 the published Long Island records of fulvescens must appear under caudelli.
