 teristic case l)ut it failed to mature. 



Family COCHLIDIID.T:. 



TORTRICIDIA TESTACEA Packard. 



Three specimens, June 13. They aj^'ree with specimens from Man- 

 itol)a and Colorado, and are probably referable to thc^ form t-ri/pfif 

 Dyar. A single larva was found on birch, but it was parasitized, and 

 died before the characteristic markings had appeared. This is the 

 westernmost record (except in the extreme Southwest) for any Cochli- 

 dian in North America. The rarity of the species jirevented as com- 

 plete observations as are desirable. 



Family (^OSSID^E. 



COSSUS POPULI Walker. 



No specimens; one in Mr. Cockle's collection, July 27, 1902, is a 

 male in good condition, expanding CO nun. It reseml)les loidnsus 

 Lintner, but the collai' is graycM- and the lin(\s on tlu^ wings are less, 

 pronounced, more broken and strigos{\ 



Family SESIID.E. 



ALBUNA PYRAMIDALIS Walker. 



Ten specimens, June 11, 18, 23, July 11 (Ainsworth), 21 (Bear Lake 

 Mountain), 28 (Bear l^ake Mountain), taken at flowers. Five are 

 normal pyrainhhiJis^ three of the variety nihcxcens^ and two of the 

 variety coJovitd nxix. The extremes suggest ditlerent species, and it is 

 not surprising that the\' were described as such. 



SESIA TIPULIFORMIS Linnaeus. 



No specimens; ojie in Mr. Cockle's collection, June 27.
