NORTH AMERICAN TETRASTHCHUS — BURKS 567 



types, Silver Spring, Md., April 6, 1933, reared from clothes moths, 

 W. S. Abbott; and 6 female paratypes, St. Louis, Mo., reared from 

 Tinea fuscipunctella Haworth, P. Ran. 



Remarks. — This species is most likely always a parasite of Apan- 

 teles carpatus (Say), and thus a secondary parasite of clothes moths, 

 although sometimes it has been said to have come from clothes moths 

 themselves. Tinea fuscipunctella Haworth, from which some speci- 

 mens were said to have been reared, is not a clothes moth but or- 

 dinarily develops in bird nests. Occasionally T. fuscipwnctella is, 

 however, a pest in carpets and other articles of wool in houses and 

 thus is undoubtedly subject to attack by the same parasites as are 

 the true clothes moths. The male of this parasite evidently is 

 quite rare.
