386 JOHN B. SMITH. 



maculation is all present, but is not very distinct. The s. t. line is 

 irregular, paler, preceded by a darkei- shade. It is larger than the 

 preceding species. 



Homogena is allied in maculation, but is much brighter and a 

 somewhat smaller species ; the lines are very distinct and are single. 

 The basal space is paler than the median, the t. p. line followed by 

 a whitish shade, darkening again to the s. t. line, which is irregular 

 and very much as in glennyi, but much more distinct. It is not 

 readily confounded with any other species. 



Oecata is a smaller species, of which I have seen only two speci- 

 mens. Its salient feature is the strongly incurved t. p. line, the small, 

 neatly marked ordinary spots, even median shade and paler basal 

 and s. t. shades. The s. t. line consists of a series of white and black 

 dashes, which are obscure in one specimen. Mr. Grote's figure of 

 the species is a good one. 



Meadlana is deep ashen gray and has the appearance of a Mamesira 

 allied to anguiiia. The lines are faintly marked, the s. t. very in- 

 definite; the orbicular is unusually large with blackish ring and 

 centre; the reniform is also dark, somewhat incompletely outlined, 

 stained with reddish. 



Fortis has the color and habitus of an Hovioliadena, as which it 

 was described and now stands in our lists. It has the deep brownish 

 fuscous color of that genus, somewhat paler occasionally, and the 

 median lines are usually punctiform, rarely lunulate, with the venu- 

 lar dots stronger. 



Despite the differences of habitus the genital structure remains 

 constant in type. 



A tabular statement of such a mixture is unsatisfactory and will 

 not be presented. The above review, aided by the detailed descrij)- 

 tions, should be sufficient. 



O. saundersiana Grt., Can. Eut. 1876, viii, 29. 



Head, thorax and primaries grayish fuscous. Primaries with basal and s. t. 

 space pale ash gray. Basal line fuscous, distinct, geminate. T. a. line with a 

 slight outward curvature, very distinct, geminate, the inner line darkest, black. 

 T. p. line bisinuate, the curvatures small, very even, distinctly geminate. S. t. 

 line pale, very deeply and prominently dentate, the teeth entirely crossing the 

 dusky terminal space and emphasized by blackish shades and dashes on both 

 sides of the line. Claviform small, distinct, concolorous, black ringed. Orbicu- 

 lar round, rather large, ringed with fuscous, within which is a pale annulus. 

 Reniform large, normal in shape, rather indistinctly defined, somewhat paler 

 outwardly and inferiorly darker filled ; median shade very distinct, rather nar-
