ACIDALIA CALIFORNIARIA Pack. 



A study of Packard's types at Cambridge, Mass., of both this 

 species and pacificaria has convinced us that the two names represent 

 a single species but that in all probability the association with sideraria 

 Gn. is incorrect. Both of Packard's forms show strongly haired palpi 

 and would fall into Prout's genus Holarctias along with rubrolinearia 

 Pack, and sentinaria Hbn. ; rubrolinearia is probably correctly placed 

 as a synonym of magnetaria Gn. as Guenee mentions the hairy nature- 

 of the head (Tete concolore, tres velue). We are not sure of the 

 identity of sideraria Gn. from the description but there is a species 

 extending apparently through the same region of California and very 

 similar in color and design to calif orniaria Pack, in which the palpi 

 are normal, showing very few traces of long hairs ; for the present, 

 in lack of any definite knowledge of Guenee's type, which should be 

 in the Oberthur collection, we apply the name sideraria to this species. 

 Apart from the less hairy palpi it may be distinguished by its rather 

 larger size, a tendency to ruddy fringes and a rather more waved and 

 more distinct subterminal dark line; rubbed specimens however are 

 extremely puzzling to locate. We are also not certain as to whether 

 californiaria may not prove to be merely a color form of magnetaria 

 Gn. ; for the present we hold them distinct. 



Xystrota suavata Hist. 



This species proves to be very close to Xystrota roseicosta B. & 

 McD. from S. Texas ; the two will probably represent races of one 

 species ; suavata has an unbroken terminal line and the s. t. line seems 

 rather more regular than in our species. Both show a double areole 

 which would place them outside of Acidalia or Ptychopoda; for the 

 present they may remain in Xystrota Hist. 



Ptychopoda lacteola Lint. (Pi. XIV, Fig. 16). 



An examination of the type in the National Museum shows that 

 this is the same species as P. pallida Hist and the name will have 

 priority over Hulst's name. We figure a specimen from Kerrville, 

 Texas. 



Ptychopoda rotundopennata Pack. (PI. XV, Fig. 6). 



The type from Brunswick, Me., is in the Cambridge Museum 

 and proves the species to be the same as that described by Hulst under 

 the name of Eois hanhami from Winnipeg, Man.; the types of this
