338 THE CANADIAN ENTOMOLOGIST 



did not seem to nie distinct from pugionis of the same collection. 

 Hampson separates ihem in the tables on the colour of secondaries. The 

 quadridentaia of the New Yoik and Washington Museum collections are 

 probably not that species. They were at any rate not pugionis. Holland's 

 figure under quadridetitata is typical niveilinea. Flavidens Smith, of 

 which I have a female from Prescott, Ariz , compared with a female type 

 from New Mexico at Washington, is a larger and altogether darker species, 

 correctly figured by Holland, but apparently wrongly by Hampson, his 

 flavidens seeming to me a suffused pugionis. 



242. E. cogitans Smith (1890), = cJioris Harvey. (1876, Hamps. Cat., 

 IV, 265). — Sir George Hampson's reference appears to me to be correct, 

 and I have specimens compared with both types. Prof. Smitli has called 

 the synonymy in question (Journ. N. Y. Ent. Soc, XV, p. 143, Sept., 

 1907), stating that he had two closely allied species in his collection under 

 the two names. Had such appeared to me the case I should certainly 

 have taken a note upon it vvhen going over his material, but have no 

 record that his choris seemed different. I took a female here on Aug. 

 loth, 1905, the only one since the male previously listed. I have a long 

 series from Stockton, Utah, Achor Strecker, described in 1899 from 

 Colorado, appears to me to be a slightly aberrant choris., browner and less 

 gray than usual The type oi choris is from Nevada. Of cogitans, there 

 are a pair of types in the Brooklyn Museum, the male from Colorado, the 

 female from California, and a pair of types from California at Washington. 



243. The specimen I have recorded from here as Euxoa perfusca Grt. 

 is not that species, but bears a close resemblance to Walker's type of 

 perkiitans from New Yoik, in the British Museum, with which I have 

 compared it. I cannot be sure that it is identical, but it resembles it more 

 closely than anything that I have yet come across. I have never taken 

 another specimen very like it. My specimen may very likely be a form of 

 tessellata. to \\\\\c\\ perie/itans seems correctly referred, so far as I could 

 judge. 



244. The species which I quite wrongly recorded as punctigera 

 appears to be undescribed, though I prefer that it should remain so at 

 present, as it may turn out to be sordida Smith, which is at any rate its 

 nearest ally known to me, but of which I have little knowledge of the 

 variation. The female (of No. 244) is of a rather uniform dull mahogany 

 brown, with the discoidal spots usually rather conspicuously yellowish 

 ringed, and has the abdomeu of that depressed shape which probably 

 caused Prof. Smith to place boretha and sordida in Chorizagrotis (Journ.
