EUCOSMA TRANSMISSANA Walker. 



One specimen, July 28 (Bear Lake Mountain) and three from Mr. 

 Cockle's collection, May 13, June 11, are apparently ver}^ near to ininx- 

 misHaixi Walker, if not really that species. The}^ may retain the 

 identification pending the receipt of more complete collections. 



EUCOSMA DORSISIGNATANA Clemens. 



Two specimens, sent ])v Mr. Cockle, taken prol)ably sometime in 



August. 



EUCOSMA PULSATILLANA Dyar. 



Three specimens, July 24, 25, 2l» and one from Mr. Cockle's collec- 

 tion, July 31. The larvae were found w(d)])ing and killing the leaves 

 of clematis. 



EUCOSMA SIMILANA Hiibner. 



No specimens; two from Mr. C'ockle's colUvtion, October 1, 1902. 



EUCOSMA CRENANA Hubner. 



Forty-four specimens, March 2t) (Mr. Cockle), June 1, 29, July 1, 

 2, 5, 0, 8, 24, 25, 31, August 4, 5, (>, 11, 12, 13, IT, and six from Mr. 

 Cockle's collection, March 29, April 4, June 6, Sej^tember 21, Octo- 

 ber 20. This seems inseparable from the European species. Mr. 

 Kearfott has recently descril^ed it as Proteopteryx eoluinhia"' with two 

 varieties, but 1 do not think the new name necessary. It is extremely 

 variable, but my European scries of six specimens match nicely the 

 forms columhla Kearfott and alhidorsana Kearfott. It should certainl}^ 

 not be placed in Proteopteryx^ which has no costal fold in the male.'' 

 Meyrick^ gives the larva on willow. A mmiber of my specimens 

 were bred from this plant, but so mixed with other species that I 

 can not give a description of the larva with certainty. 



THIODIA APACHEANA Walsingham. 



Eight specimens, June 23, 24, and one from Mr. Cockle's collection, 

 June 11. They agree well with one from Los Angeles, California 

 (Koebele), identified by Lord Walsingham in 188T. They are a little 

 larger and the markings seem brighter, w^hich is probabh" due to their 

 being fresher. In going over this species with Mr. Kearfott we 

 concluded that it was Eucosma alhangulana Walsingham; but in this 

 we were hasty, as the male has no costal fold. It resembles the figure 

 of that species, however.

''As this is in press I see that Professor Fernald corrects Lord Walsingham' s diag- 

 nosis of Proteopteryx to include the costal fold. Can. Ent., XXXVI, 1904, p. 120.
