Goosensiata, Mab. 



Minutata, Gn. 126 



Knautiata, Greg. 22 



Absinthiata, Clerk. 84 



We can see little difference in these three forms. We had 

 considerable difficulty in obtaining reliable material for 

 knautiata, many specimens sent as this species show only 

 assimilata genitalia. There is little doubt it is only a 

 variety of minutata. 



Valva fairly large. Cornuti five, four scobinate, one 

 plain with base. Coremata sessile, hairs many, long. 

 Saccus rounded. 



Ostium weak. Ductus burses short. Bursa panni- 

 cular. 



Assimilata, Gn. 105 



Valva generally smaller than preceding species. Cornuti 

 four, three scobinate, one with base. Coremata globular, 

 hairs long. Saccus rounded. 



Ostium weak. Ductus bursae short. Bursa instrate. 



Vulgata, Haw. 105 



Valva almost pointed. Uncus small, sharp, point. Cornuti 

 three, scobinate. Coremata globular, hairs long. Saccus 

 rounded. 



Ostium weak. Ductus bursse short. Bursa pannicular. 



Valerianata, Hb. 32 



Valva rounded. Cornuti two, one broad scobinate; one 

 small finely scobinate. Coremata pedunculate, hairs long. 

 Saccus rounded. 



Ostium weak. Ductus bursae short. Bursa pannicular, 

 a very distinct central patch of spines. 



There appears to be a difference between our examples 

 and that figured by Dr. Petersen. 



Irriguata, Hb. 34 



Valva peaked. Uncus tapered. /Edceagus broad. Cornuti 

 three, one scobinate; one scobinate with corrugated base;
