Types: Catalogue No. 12725 U. S. N. M., the above speci- 

 mens and a slide bearing a head of each sex, a male first femur 

 and three female caudal legs. 



The species is parasitic on a Scymnid larva which preys 

 upon Lecanium oleae on orange, San Luis, Mexico. Also at 

 Monterey, Mexico, from the larva of Azya orhigera. The 

 scutellum has a delicate cross suture near its apex. 



Polynema piceipes Girault. 

 The legs are concolorous as the name indicates. 



Collecting Papaipemae (Lep.). 

 By Alex Kwiat, Chicago, Illinois. 



My object in writing on this subject is not particularly to 

 recount my own experiences but to serve as -a guide to others, 

 who, by its aid, might become interested and succeed in adding 

 to our knowledge of the various species of Papaipema and 

 their life histories. 



A great deal of careful and painstaking work on this group 

 has been done by Mr. Henry Bird and others during the last 

 eighteen or twenty years and the results published from time 

 to time. My intention is merely to summarize a few of the 

 known facts so that anyone who wishes to do so can seek in- 

 telligently for the larvae of species whose food plants and 

 habits are known and rear them to maturity. Anyone work- 

 ing along the lines suggested will not 6nly add materially to 

 his collections but also may discover new species and the life 

 histories of others hitherto unknown. 



In general the larvae of the Papaipemae are borers in the 

 stems or roots of persistent annuals or perennial plants and, 

 in at least one instance, in the young shoots of an indigenous 

 tree. 



The moths appear rather late in the year, the earliest spe- 

 cies about August 15th and thfe latest about October 5th. They 

 are sluggish of habit and seldom fly far from their breeding 

 place. This sluggishness and the late period of flight accounts 

 for their scarcity in collections. 



Eggs are deposited on or near the food plant and hatch the
