Rhizagrotis defectipes Dyar. 



1921, Dyar, Ins. Insc. Menst., IX, 63, Cerapoda. 



This insect is not a Cerapoda but represents a Rhizagrotis prob- 

 ably conspecific with albalis. The secondaries are a Httle darker than 

 typical for albalis which is however a very variable species. The 

 Barnes Collection possesses a single specimen from Montana (Miles 

 City) which had heretofore been placed as albalis. More material 

 from Montana will be necessary in order to form a conclusive opinion. 



Feltia volubilis form dentilinea Sm. 



1890, Sm., Trans. Am. Ent. Soc, XVII, 45, vohibilis form, "S.". 



1917, B. & McD., Check List, p. 44, No. 1409 form, volubilis form, Feltia. 



No specimens were found labeled type in either the National 

 Museum or Smith Collections and apparently the types were either 

 not labeled by Smith or have been lost. No locality is given by Smith 

 in the original description and the name appears to have been over- 

 looked by him (1893, Bull. U. S. N. M., XLIV), by Dyar (1903, Bull. 

 U. S. N. M., LIT), and, by Hampson (1903, Cat. Lep. Phal. B. M.). 



In the Smith Collection two specimens are placed a little to one 

 side of the series of volubilis. One is labeled "Ct.", and somewhat 

 resembles musa without the t. p. line so distinct, but with the costa of 

 volubilis. The other specimen is labeled "Colo." "Hulst" and appears 

 to be the Colorado representative of acncipennis, but is longer winged. 

 Probably neither of these represent the "type" of dentilinea which was 

 described from "a number of specimens". 



Judging from the inadequate description of dentilinea the name 

 might well represent typical volubilis, and stigmosa Morr. might be 

 available for the slightly duller form. This, however, appears to be 

 splitting too finely. The name dentilinea may tentatively remain on 

 lists as an unknown form of vohibilis. 



The authors are indebted to Messrs. Schaus and Ilg for carefully 

 checking the negative result of the attempt to locate types of dentilinea 

 at the National Museum and Smith Collections.
