consider them as distinct until future investigation shall determine their 

 true position. The lower wings of the Salt Lake forms are clear white, 

 while those from Denver are smoky. 



Orgyia leucographa Walk. (Lep. Meter. B. M., p. 1723.) 

 I have before me 7 examples of a form of Orgyia, which to say the 

 least, are very extreme varieties of the common species. In the first 

 place, there is a marked difference in size. O. leucostigma being much 

 larger than the specimen under consideration. The color is uniform 

 stone drab, with the lines very faintly marked, and the usual dark costo- 

 apical entirely obliterated in 3 of the specimens, and only very faintly 

 shown in the remaining 4. The white posterior spot near the internal 

 angle, is also very faint in 2 specimens, stronger in 2, and quite distinct 

 in the other'3. The ground color of all however is the same, stone drab, 

 instead of brownish drab. Two Qs of this form are also very much 

 slighter and smaller than those of 0. leucostigma. Could Walker have 

 had this form before him when describing O. leucographdi He must 

 have been well acquainted with 0. leucostigma, as on page 7S6, I.e., he 

 quotes Smith & Abbott's description, and therefore he cannot in his de- 

 scription of O leucographa refer to the common form of the well known 

 species. HoweveV, should this surmise prove incorrect, I propose for 

 the present insect the varietal name of . obliviosa . My examples are 

 all from New Jersey, and are by no means faded, as 3 of them were rais- 

 ed from cocoons found on maple. 



Apatelodes indistiicta n. sp. 



Primaries of a grayish drab, tinted with reddish, the lines and marks all obsolete, 

 the suiface dotted with black irrorations. There is near the apex a semi-transparent 

 square spot, with a smaller one beneath it. The fringe is reddish chestnut. The 

 secondaries are reddish testaceous, without marks. Underside wholly reddish fawn- 

 color, with a few black and brown specks, but wholly without the dark shading so 

 conspicuous in A. torrefada. Thorax, color of primaries. Abdomen reddish testa 

 ceous with brown dots. Expanse of wings 35 mm. Length of body 18 mm. 1 ^.

Apatelodes torrefacta var. Floridana n. var. 

 In this form, which I have never seen, except from Florida, the 

 wings have a much redder shade, the secondaries being almost dull brick 

 red. Th-e double brown spot on the internal margin near the base, is 

 much smaller than in the typical form, while the whitish shade on the 

 abdominal margin of secondaries is almost wanting. The lines are all 

 much fainter, the discal whitish spot, as well as that at the apex, being 

 much more clearly defined. Beneath, the wings are foxy red, darker at 

 the apex of primaries, with the bands only very faintly marked. It is 

 possible that we may have to do with a distinct species. Specimens are 

 in my own collection, and that of Mr. 13. Neumoesren,
