Two females labeled: Gipsy Moth Laboratory, No. 820-0, 

 1907. One male, labeled: Washington, D. C, F. D. Couden, 

 Coll. Adult issued October 2, 1907. All three specimens reared 

 from Hemerocampa leucostigma. 



This species has been collected in the field at Melrose High- 

 lands, Massachusetts, the female specimen bearing Gipsy Moth 

 Laboratory No. 1976 being indistinguishable from the above 

 specimens. 



The genus Sisyropa, which belongs in the subfamih^ Hemi- 

 masiceratinae, may be distinguished from the closely similar 

 genus Eiimasicera (described below) of the Masiceratinae as 

 follows : Sisyropa has the face and front of female very narrow, 

 nearly equilateral, and equal to width of one eye; cheeks and 

 parafacials extremely narrow, the latter at narrowest equal to 

 half length of second antennal joint or even less; eyes thickly to 

 densely pilose; palpi moderately stout basall}^ a little enlarged 

 at tip; scutellum and abdomen with thickly placed erect hairs; 

 apical pair of scutellar bristles long ; antennae inserted well above 

 eye-middle. Reproductive habit, larviposition.
