reference of contagionis to Euxoa must stand. Porosagrotis 

 is recognized by Hampson, and distinguished from Euxoa, ( i ) 

 by the stoutness of the fore tibial armature and (2) by the 

 male clasper being falcate instead of bifurcate. The former 

 character is not a well-marked one, and can hardly be distinc- 

 tive. The form of male clasper, on which Prof. Smith based 

 the genus, he states to be striking and quite constant. Sir 

 George Hampson appears to take this for granted, as he gives 

 no figure. Pro- and metathoracic crests in Euxoa, absent in 

 Porosagrotis, is the only other distinctive character mentioned 

 by Hampson, but this is not well marked either, as I find such 

 crests in both vetusta and satiens, placed by him in Porosa- 

 grotis. 



Mamestra tenisca Sm. 



Described in the same journal from Stockton, Utah, and 

 Bozeman, Montana. I saw the type in Prof. Smith's collec- 

 tion, beside specimens of stricta from Stockton which he does 

 not mention having. Tenisca seemed to me a very close ally 

 of stricta, but distinct. I have no compared specimen, and 

 though I have one of the species from Stockton, my notes do 

 not enable me to feel sure which. 



Mamestra meodana Sm. 



Described as a close ally of liquida yet, and said probably 

 to occur over a similar range. Of its validity as a species I am 

 very doubtful. Typical liquida Prof. Smith states to be narrow 

 winged and brighter colored. I saw the type from Washington 

 in the British Museum, but did not note that it was brighter 

 or narrower winged than Calgary specimens which were there 

 also. Hampson figures the type, and I passed the figure with- 

 out other comment, so assume it to be good. It appears a 

 little narrower winged and more contrasting than Calgary 

 specimens, which are typical meodana. But as those figures 

 are sometimes a trifle inaccurate in detail, it is unsafe to judge 

 from one with respect to such a closely allied form as the pres- 

 ent. But assuming Prof. Smith to be correct in stating that 

 liquida is the bright form, I studied his t\vo series together and
