especially at the base, are lighter than the discal portions. The 

 adult measures to the tip of the wings 25 mm. (i 

 inch) or more. Although this is a native species,

 being attracted by lights at night. 



Among our species of cockroaches are many 

 wingless forms. One of these is represented in
