NORTH AMERICAN LASPEYBESIINAE AND OLETHREUTINAE 75 



cycle from adult to adult is completed in a little over a month (35 

 to 40 days) in early and middle summer. Larvae are to be found, 

 therefore, in nearly all stag;es from late May to early November (our 

 last field date for the vicinity of Washino:ton is November 10). 



A few specimens have been reared by W. G. Boyd at Weir, 

 Miss. ("7-14-1923") from larvae boring in stems of Wisteria. As 

 this is an introduced plant, the infestation was probably accidental or 

 is evidence of a new, acquired habit. I laiow of no records other 

 than this upon any host but Rohinia. 



Genitalia figured from reared specimens in National Collection 

 from Falls Church, Virginia (" Hopk. U. S. No. 12103 Z, issued 31 

 July 1914," male; and "Hopk. U. S. No. 12103 n, issued 26 June 

 1916," female).

 insiticiana (of which it may be only an aberration) except by the 

 genitalia. The differences in structure are shown in figures 115, 117.
