Cocoon of silk. 



APATELA FELINA Grote. 



Three specimens, June 13, 16, 25. Mr. Cockle has had this species 

 in his collection as canadensis Smith and D3'ar, but it does not agree 

 with our type, which was from Calgary, Alberta. It is, however, like 

 specimens before me named felina, by Prof. John B. Smith. The 

 Kaslo specimens agree in color with one labeled "Wash. T. ;'"' Cali 

 fornian specimens are lighter. This error in identification illustrates 

 the resemblance of the Kootenai fauna to that of distant California, 

 whence felina was descril)ed, rather than to that of the near eastern 

 foothills of the Kocky Mountains toward Calgary.
