A decidedly variable si)ecies, the pale more unicolored forms of which 

 are usually marke«l aenelpennin in collections. 



The type of ra»ro«rcr('M,v/,s' is larf>e and fully marked; that of .sym/- 

 vUirata smaller, and with the transverse markings obsolete, A series 

 of eighteen specimens proves the undoubted identity of the forms. 

 (Uodinna also is but a Ibrm of this s])ecies with the maculationsoMiewlmt 

 obscured. The ligure in the illustrated essay is very poor. Hortulana 

 Morr., is one of the forms allied to aeneipennis. To give a better illus- 

 tration of the forms, the original description of each is reproduced." 



A grot is vancouverensis Grote. 



" $ Light brown with pale shadings, A very broad distinct basal 

 dash, wi«lening outwardly, extends into the median space, apparently 

 concealing the claviform. T, a, line strongly dentate interiorly. Dis- 

 cal s]>ots set in the black fdling of tlu^ cell. Transverse ])osterior line 

 unusuidly sharply denticulate; the i)ale subterminal line i)receded by 

 large cuneiform brown marks. An interrupted black terminal line on 

 the margin; fringes light brown. Hind wing fuscous without mark- 

 ings, save from the rellection of the black and distinct discal liture of

"A rather large, broad-winged si>ecies, allied to .4. oheliscoides and
