 .serratiiria. Tlie I)rea(ltli of the coilee-colored border varies sometimes, as in 

 a Kansas sjxicimen whieli is dark eolli'e-hrown, with the outer third of tiie 

 the wings but a shade darker tlian the interior.

This is an exceedingly variable species. It is ol' the same size, and 

 very nearly allied to E. se.rrataria, but is never so yellow, and the wii'igs arc 

 less serrate, especially on the posterior half of the hind wings, which in 

 several examples is not serrate at all. Certain females are unilbrmly pale 

 ash-brown, of the same hue as in E v'mulentaria, diifering in this respect 

 from any of the allied serrated t(>rms. Other females are yellowish-brown, 

 but still much less yellow than in senataria. Usually, however, in both 

 sexes the wings are broadly margined with l)rown, with two or three lda<dv 

 apical spots, and the discal dots are large and distinct. The specimens are 

 always lighter than in effectaria, and less yellow than in serrataria. 



Although it does not exactly agree with Guenee's description of tigri- 

 naria, yet it does in the most important characters. He says the extradiscal 

 line is not bent below the costa, but it is usually nearly as nmeh bent as in 

 E. pe.ctinar la, though in worn specimens the l)eud is indislincf. It is evi- 

 dently his ohtusaria Hiibner, as individuals agree well with his de.-^eription. 



Larva. — Rather thick; body of tiniforni thickness thnmohout, with the 

 head no wider than the body, which is smooth, less tuberculated than usual, 

 there being oidy one or two small (lor.-<al tul)ercles near the end of the body. 

 The body is pale gray, with brown blotcdies, and subdorsal series of reddish 

 longitudinal lines. Food-plant hnpatkm itoli-me-tuttgcre. — (Described from
