flattened, scales. Fore tibiae slender, unarmed. Head clothed with long black 

 and white hairs. Thorax clothed with long white hairs with some admixture 

 of black, appearing whitish. Abdomen mainly clothed with black hairs. Pri- 

 maries deep black with a bronze sheen, the scales rather broad, not as heavily 

 scaled on the distal third as on the mesial tv/o-thirds ; fringe pure white. Sec- 

 ondaries entirely similar in coloration to the primaries. Beneath : similar to 

 upper side. 



Expense: 19-21 mm. 



Vettation: essentially the same as in Canephora unicolor Hufn., (see 1906, 

 Spuler, Schmett. Europ., II, 174), but in the specimens of both species examined 

 by the authors, the basal half of vein \c of the primaries is somewhat stronger 

 in polingi, being about half the strength of a normal vein. Fore wing with 11 

 veins, la anastomosing with \b in the central third of the wing and then run- 

 ning toward the inner margin. Hind wing with 7 veins; with a bar between 

 veins 7-8 near middle of cell; 4, 5 variable, stalked or connate. 



Differs from E. carhonaria Pack, by the paler thorax, bronze sheen 

 and broader scales on the wings, the more translucent distal portions 

 of the wings, and the white fringes, primaries with outer margin 

 straighter, more oblique, the apical angle more acute. 



Mr. F. M. Jones has kindly donated a freshly bred specimen, and 

 case, of carhonarin, taken within a few miles of Mr. Belfrage's collect- 

 ing ground in Texas. 



Mr. O. C. Poling, in whose honor the present species is named, 

 collected cases of a Psychid on "tar-weed" in the immediate vicinity 

 where he caught the long series of polingi, and stated in a letter that 

 he believed these cases furnished some of the adults he had caught. 

 The cases are very similar to those collected in Texas by Mr. Jones, 

 and from which he bred specimens of carhonaria. These two species, 

 altho distinct, are structurally closely allied and differ from the re- 

 mainder of the described North American forms. ^ It is, therefore, 

 likely that Mr. Poling is correct in his association of bag and adult. 



Bags: presumably of E. polingi.. About 34 mm. in length, by 3 mm. in 

 diameter at the widest part which is about 10-12 mm. from the larval cephalic 

 end ; from this widest part, tapering somewhat cephalically, and to almost a 

 point, about IJ^ mm. in diameter, at the caudal end; thatched with very small 

 fragments of what appears to be chewed bark or wood, the fragments so small 



sAccording to correspondence between Dr. Burrows, who examined the type of 

 edwardsii Heyl., and Mr. Jones, the name represents a very close ally to the European 

 C. unicolor, but the scaling is fine and hairlike. The original description states that the 

 fringes are black, and give Texas as the locality. Mr. Jones, Mr. Dyar, and the authors 

 are now in accord that this name will probably prove conspecific with carhonaria, and will 

 have priority.
