With regard to duaria Gn. we have long been dissatisfied with 

 the heterogeneous mass of forms included under this name. Until M. 

 Oberthur completes his publication of figures of Guenee's types it 

 will always be a little difficult to determine the nimotypical form espe- 

 cially as the descriptions of both duaria and the following species 

 hamaria Gn. (which both Packard and Hulst after having examined 

 the type specimens make a synonym) are rather vague in certain direc- 

 tions. The name duaria was based on a single 9 type from Canada 

 (presumably Ont. or Que.), the color is given as a clear testaceous- 

 gray (gris-testace clair) with only a slight black sprinkling, the tw T o 

 cross lines of the primaries are wavy and black (ondulees noiratres) 

 with darker bordering shades leaving the median space clear; the 9 

 which we figure on PI. XXIX, Fig. 5 appears to us in the light of this 

 description to be typical; the $ , which we also figure, (Fig. 4) is very 

 similar but rather deeper in color ; the species seems to extend across 

 the continent from the Atlantic States through Canada and the North- 

 ern States to British Columbia ; we have specimens before us from the 

 Eastern States, Penn., neighborhood of Chicago, Manitoba and Van- 

 couver Is., B. C. According to our notes on Walker's types in the 

 British Museum panisaria Wlk., amyrisaria Wlk., agreasaria Wlk., and 

 adusiaria Wlk., will all become synonyms of the typical form. Apart 

 from the fact that the subterminal blotches may be absent and that the 

 cross-lines tend to lose their wavy nature the variation in this form is 

 not very great; the dark sprinkling over the wing is fine and evenly 

 distributed, the basal space of primaries a rather dull purplish gray, the 

 median space wide and rather paler, the t. p. line on both wings fol- 

 lowed by a rather obscure broad pale purplish shade ; on the underside 

 the lines, especially the t. p., usually form purplish bands, the veins are 

 yellow and the sprinkling is much heavier and more purplish, especially 

 in the $ ; in both sexes the wings show a distinct angle at vein 4. 



With regard to hamaria Gn. which, as already stated, is placed by 

 Packard and Hulst in the synonymy of duaria we must confess that 

 we have not been able to satisfactorily identify this from Guenee's 

 description ; the color is given as testaceous mixed with reddish (testace 

 mele de rougeatre) sprinkled heavily with dark atoms and in the place 

 of the cross-line Guenee mentions two blackish shades, wide apart on 

 the primaries and close together, parallel and subterminal on the secon- 

 daries ; from this it is evident that we are dealing with a much redder 

 form with indistinct maculation ; we imagine the second subterminal
