almost, certain that Riley's original series of P. y-inversus was col- 

 lected in the southern part of Hidalgo County — the only area of 

 New Mexico in which Y. schottii is known to occur. 



When distrubed in the flowers, the adults of P. y-inversus are 

 more apt than other yncca moths to abandon the flowers in an attempt 

 to escape. Usually they either drop or fly to the leaves immediately 

 below and quickly move to the leaf axils where they are protected 

 from most predators — ^including entomologists. 



On two occasions, adults of P. y-inversus were observed to have 

 fallen prey to a crab spider, identified by Mr. Vincent Roth of the 

 Southwestern Research Station as Misumenops coloradensis Gertsch. 

 This spider frequently is encountered in the flowers of Y. schottii 

 and probably constitutes a constant menance to P. y-inversus. Simi- 

 larly, this moth is also attacked while resting in the flowers by the 

 adult of Enoclerus spinolae (LeConte).
