species unknown to ME. 

 Xylophasia libera Wlk. 

 1856. Wlk., Cat. Brit. Mus. Lep. Het. ix, 170. 



" Testaceo-cana ; thorax fascia vittisque duabus nigris; alse anticse 

 disco et margine exteriore ex parte fuscis nigro strigatis, strigis dua- 

 bus lunulisque marginalibus liturisque costalibus nigris, annulis dis- 

 calibus nigromarginatis ; posticse cinerese, ciliis pallidis," 



" Xylophasia cariosa f " 



" Male. Testaceous, hoary. Thorax with a black band in front, and 

 with a black stripe on each side. Fore wings partly brown, and streaked 

 with black in the disk and along the exterior border, in the middle of 

 which there are two lanceolate streaks ; a row of blackish marks along 

 the costa ; discal ringlets with black borders ; exterior border with 

 black lunules. Hind wings cinereous with pale cilia3. Length of the 

 body 5 to 6 lines, of the wings 14 lines." 



" New York." 



It is scarcely likely that this description refers to any species not 

 herein described under some other name, and probably Walker's own 

 suggestion of cariosa is the true one. 



Mr. Grote (111. Essay 44), refers this to Mamestra grandis, as a syn- 

 onymn ; but the description can scarcely be tortured into application 

 to that species, while it does agree very well with X. cariosa. 



Xylophasia infixa Wlk. 

 1856. Wlk., Cat. Brit. Mus. Lep. Het. ix, 178. 



"Subcervina; caput et thoracis fascia fuscescentia; alse anticae 

 punctis costalibus, vitta discali striga posteriore strigisque exteriori- 

 bus nigris; posticie pallide cinereaj, marginibus latis fuscescentibus."
