As the species is difficult to describe we give figures of both 

 species which should show the salient points of distinction better than 

 a mere description; we have a good series of mcmoriata before us 

 and the differences seem perfectly constant; both species occur in the 

 same locality and are alike in structure. 



Cleora (Selidosema) dionaria sp. nov. (PI. XX, Fig. 6). 



Primaries whitish, rather heavily sprinkled with smoky and with a yellow- 

 ish tinge on the veins in the neighborhood of the cross-lines; four obscure 

 equidistant smoky patches on costa giving rise to cross-lines of which the first 

 is obsolescent, outwardly rounded and closely approached to the second at 

 inner margin ; the second corresponds to the ordinary t. p. line, is not very 

 distinct, inwardly oblique and slightly dentate ; the third is bent out below costa 

 forming an angle in which a discal ringlet rests, then irregular to inner margin 

 and approximate to t. p. line; the fourth or t. p. line is the most distinct of 

 all, evenly dentate, rounded outwardly below costa, then oblique inwardly to 

 inner margin above which it forms a rather prominent inward excavation with 

 an outward angle on vein 1 ; following it is a slight brownish shade, most 

 distinct on the veins ; s. t. line obscure, pale, dentate, preceded by smoky shade ; 

 a black scalloped terminal line, accentuated at base of scallops by a dark dot; 

 secondaries similar to primaries in color, with a distinct dentate t. p. line and 

 a somewhat larger discal ringlet. Beneath silky whitish, costa of primaries 

 pale ochreous, blotched with smoky; faint discal ringlets and dark terminal 

 line to both wings. 



9 . Whiter than the $ with prominent discal ringlet on secondaries. 

 Expanse $ 40 mm. ; 2 45 mm. 



Habitat: Palmerlee, Ariz. 4 $, \ 9. Types, Coll. Barnes. 



Very similar to grisearia Grt. but larger, less contrasted in colora- 

 tion and with a discal ringlet on secondaries instead of a dot ; it is also 

 allied to fiirfuraria Hist, but separated readily by the ringlet; the S 

 shows no hair-pencil on the hind-tibia. 



Cleora porcelaria Gn. 



This species, which was not definitely recognized by either Pack- 

 ard or Hist., was doubtfully placed as a synonym of umbrosaria Hbn. 

 by Hulst in Dyar's List (p. 325) and this reference was followed by 

 ourselves in our recent Check List. The types are stated to be 3 $ 

 in Coll. Paris Museum and Boisduval ; M. Oberthur states (fit. Lep. 

 Comp., VII, 274) that no specimen exists in his collection ex Coll. 

 Boisduval and we were unable on our last visit to Paris to find any 

 type specimens there so that we must conclude that the types are 

 probably lost.
