NOETH AMERICAN LASPEYRESIINAE AND OLETHREUTINAE 21 



mene), spiniatia Duponchel and fimhriana Haworth have the abdo- 

 men simple; trauniana (type of Pammeiie)^ oxycedrana Milliere, 

 spJendidulana Guenee and amygdcdcuna Duponchel have a tuft on 

 sixth segment only; argyranu (type of Pseudotoinia), Juliana Curtis, 

 gallicolona Zeller, christophaiia Moeschler, regiana Zeller and our 

 four North American species have tufts on abdominal segments 

 6 and 7; rhediella Clerck (type of Hemerosia) has them on 6, 7 and 

 8; flexana Zeller (type of Strophedra) has lateral tufts on the eighth 

 segment like these of Grapholitha, otherwise the abdomen is smooth. 

 This last has other differences also ; the fore wing has termen decid- 

 edl}' slanting, costa sharph' bent at apex and apex somewhat pointed 

 and produced and veins 3, 4, and 5 widely separated at termen. 

 Very likely when larvae and pupae are studied it may be found ad- 

 visable to divide the genus. In that case all the above synonyms will 

 take their places as valid genera and the American species be referred 

 to Heinerosia. At present nothing would be gained by splitting. 



It is unfortunate that the name Ilenmnene, which has hitherto 

 been used for the moths now under Dichroravipha, must be sub- 

 stituted for Pauimene; but the fixing of populana as tyj^e by 

 Walsingham and Durrant (1901) compels it. 



In Europe the larvae are leaf tiers, feeders in galls (inquilines) or 

 under bark of forest trees. The larvie of none of our American 

 species are known. 



Derived from and a higher development of Laspeyresia.
