Arizona and Colorado, and, as the type of maculation and structure was 

 unusual for the eastern fauna, I questioned whether the locality of the 

 specimen in the Tepper Collection might not be erroneous. An examination 

 of Dr. Harvey's type in the British Museum confirmed my belief; and in my 

 Catalogue of 1903 (Bull. 44, U.S. Nat. Mus., 79) I cited the two names as 

 referring to the same species, and gave the New York locality with an " ( ?)." 

 Until 1907 I did not see another eastern example, though I had a number 

 from southwestern localities. In a miscellaneous lot received from Dr. 

 Dyar for determination, there was an example which I named acclivis, 

 and to which I appended the note quoted by Dr. Dyar: "The first authentic 

 specimen I have seen from this region. It indicates that the Nev/ York 

 locality which I questioned in my Catalogue may have been correct, or it 

 may indicate two very similar species which I have not had material enough 

 to discriminate." 



Dr. Dyar did have material to discriminate, and he gives the differences 

 between the eastern and the southwestern forms; but in giving a name he 

 re-describes the eastern form that served Morrison as a type, and therefore 

 creates a synonym merely. I assume that Dr. Dyar is correct in determining 

 that there are two species, though I have not been able to verify that point; 

 but, if this is so, it simply means that Dr. Harvey's name must be restored 

 to the list and that the southwestern specimens now labeled acclivis Morr. 

 in collections must be re-labeled opaca Harvey. 



Euxoa cocklei nov. sp. 



Head, thorax and primaries dull brown, varying from chocolate to smoky, and 

 more or less irrorated with black. Collar with a more or less marked black median 

 line. Disk of thorax and patagia with a sparse admixture of yellow scales. Prima- 

 ries with all the maculation traceable, and usually v/ell written. Basal line geminate, 

 black, included space yellowish. T.a. line geminate, included space yellow, the 

 edgings black; upright to median vein outcurved in the space below and outwardly 

 bent below vein 1. T.p. line geminate, inner portion lunulate, not well marked, 

 outer portion hardly distinct; the included space yellowish, variably marked and 

 not always continuous; in course moderately outcurved over the cell and then par- 

 allel with outer margin. S.t. line a little irregular, broken, yellomsh, sometimes 

 reduced to scattered yellow scales. A series of dusky terminal lunules, which are 

 rarely distinct. There is a tendency to a darkening below the median vein, between 

 the basal and t.a. line, and in one example there is a distinct black line. Claviform 

 moderate, black-bordered. Orbicular round or oval, moderate in size, with a nar- 

 row black edging within which is a ring of whitish scales. Reniform moderate in 

 size, kidney-shaped, edged with black scales, then with an inner (more or less 

 incomplete) border of yellowish; the spot sometimes darker inferiorly. Secondaries 

 •smoky yellowish, almost uniform, with an obscure dusky lunule. Beneath, dull
