Wings hyaline, with the usual venation; third vein with eight to 

 ten hairs at base, reaching halfway to cross vein ; third costal segment 

 slightly longer than fifth : no costal spine. Epaulet black, subepaulet 

 yellow. 



Female. — Front 0.31 of head width (average of two, 0,30 and 

 0.32) ; the usual orbitals present, lower frontals as in male. Middle 

 tibiae Avith two or three bristles on outer front side. Tufts of white 

 or yellow hair on sides of scutellum as in male. Genital segments a 

 little reddish, the organs much retracted. 



Length of male, 10 to 11 mm.; of female, 8 to 10 mm. 



Described from one male, Brownsville, Texas, collected by T. C. 

 Barber in June, 1922; and from three lots, all from James Zetek: 

 (a) One male and six females, reared at Ancon, Canal Zone, from 

 dead Murex; (&) one male, one female, reared at Fort Amador, 

 Canal Zone, from Hylesia., species, which we assume was dead to 

 begin with; (c) four males and four females, reared at Ancon by 

 one of Mr. Zetek's predecessors, but the data are now lost. This 

 third lot are paler in color of pollen, and the lateral scutellar tufts 

 are yellow instead instead of whitish, but the puparia show no dif- 

 ferences. The type and allotype are from the lot a. Mr. Zetek's 

 numbers for the three lots are Z-2305, Z-2303, and Z-1834, re- 

 spectively.
