Type-locality. — Coach ella Valley, Calif. 



Allotype-locality. — Presidio, Tex, 



Type.— C^t. No. 27688, U.S.N.M. 



Five females and one male all reared by Alan P. Dodd, of the 

 Prickly Pear Board of Australia from lepidopterous larvae boring in 

 Opuntia. 



All but one of the specimens were reared as parasites of Cactobrosis 

 strigalis Barnes and McDunnough, Paratype 6 having parasitized 

 Zophodia glaucatella Hulst. Paratype a is from the allotype-locality, 

 Paratype h from Uvalde, Texas, and the other two, which are returned 

 to Mr. Dodd, are from the type-locality. 



Paratype a and the two returned to Mr. Dodd are essentially like 

 the type while Paratype 6 is even less extensively and less distinctly 

 marked than the allotype.
