CORYPHISTA MEADII Packard, var. BADIARIA Henry Edwards. 



Five specimens, June 13, July 21, 25, 31, August 1. Both forms 

 occurred, meadil being" the usual one. The true hadiarki looks very 

 distinct, and Mr. G. W. Taylor has pointed out to me that there 

 are no intergrades, yet I think it is onlj^ a varietal form. A t3^pical 

 hadiarla was bred from a larva on barberry. My description of the 

 larva of hadiarla" should be applied to ineadii^ as we took no true 

 hadiaria in Colorado, though one specimen is very near it. The two 

 larvffi are, however, indistinguishable. I observed all the stages in 

 the Kaslo specimens. 



HYDRIA UNDULATA Linnaeus. 



One specimen, Jul}" 21 (Bear Lake Mountain, CurrJe and Caudell). 

 Observations on this larva should be made. I have described the 

 eastern form,^ but in the West Primus serot'ma^ the food plant, does 

 not occur, nor have the peculiar nests of the larvje ever been noted, so 

 far as 1 can discover. 



EUSTROMA DESTINATA Moeschler. 



Sixteen specimens, August 11 (South Fork Creek, Mr. Cockle), 20 

 (West Robson), September 7 (Glacier), 8 (Glacier), (Field). None 

 taken at Kaslo, though Mr. Cockle has some in his collection. 



EUSTROMA POPULATA Linnaeus. 



Two specimens, July 21 (Bear Lake Mountain), Sandon (G. C. Rob- 

 bins). They are of the variety pachirdata Lintner, agreeing exactly 

 with a specimen from Yosemite, California (J. B. Lembert), and less 

 closely, but still very nearly, with Lintner's type before me. There 

 are a number of differences between this form and the European ^«9jO- 

 ulata., and I suspect that packardata will be found to be a distinct spe- 

 cies. I have specimens of the true j^opulata from Clatsop County, 

 Oregon (H. Alilers), and Wellington (T. Br^-ant). Mr. Cockle has 

 latterly sent me a true pqpnlata from his collection, taken August 10 

 (South Fork Creek). 



EUSTROMA CERVINIFASCIA Walker. 



One specimen, August 13 (Sandon, Mr. Currie) and two from Mr. 

 Cockle's collection August 10 (South Fork Creek) and August 13, 1902, 

 all three females. The specimens are alike and agree well with the 

 original colored figure of Walker's type which Doctor Packard used for 

 the figure in his monograph. They differ markedly from popidata ?ind
