aiulessentially alike ill the species. Theharpes are suddeiily narrowed 

 anil rectau^iularl.v bent, tlie tii) variously dilated and iVin^^ed. The 

 hind niar;4in is always thiekenetl autl corneous, the claspers various, 

 and sei)arately described for each species. 



Variolata is blotchy. The jjround color is yellowish fuscous, some- 

 what olivaceous. The uiacidation white and contrastingly. A yellow 

 shade runs across the wing through median si)ace, and the apex is con- 

 spicuously white. 



Glaciatd is much more even, grayish olivaceous m color, the lines and 

 or<linary si)ots white marked but scarcely blotchy, as iu the preceding. 

 There is a distinct white spot beyond theclaviform. 



Minorata is smaller, of the same ground color and with essentially the 

 same markings as {/laciata. It lacks the white spot beyond the clavi- 

 form, and in its place has a dark shade crossing the median space. 



In tabular form the differences show as follows: 



Lar^e, black ; orbicular small adjl'NCTA. 



Moderate sized, color variable ; orbicular large. 



Maculatiou blotchy, ground color yellowish fuscous, an apical white 



patch VARIOLATA. 



Maculatiou not blotchy ; no apical white patch. 



A white spot beyond claviforuj ; t. a. line sinuate and dentate GI.aciata. 



No such white spot : t. a. line very even, upright minorata.
