/v>-. /oiru. <tml jHip,i,— V\n- r<y<r is oval-cylimlrical, yellowish, the shell 

 niiich thinner, and less dense, and ron<rlier than in .f. unlumiKita. 'i'liey arc 

 laid in piles irre<rnlarly, iio( in Dal cakes, side l.y side, as in auhimmita. The 

 larva is brown as a i,n-()und-eolor, with three broken, partly obsolete, while, 

 dorsal threads, a broad, brown, subdorsal band, nearly twice as wide as the 

 dorsal striped area A lateral, broad whitish area broken by two broken brown 

 lines, the lower part of the band being whiter than on Ww upper edire, and 

 I'orniing a narrow brok.'U line more or less marbled with brown. This broken 

 white line is the only line contrast inir with the brown bodv, while in 

 (uitumnata tii(>re are as a rule sevei'al such while lines. Jieneath. a broad, 

 whitish, median line, contrasting with the flesh-colored under surface. 



The tendency to variation is in this species shown to consist iii (he l)odv 

 being whi(er, the dor.sal area being ])ale, wi(h a dark lateral line, some speci- 

 mens l)eing pale, with a broken lateral line sonu'times represented ]»v isolated 

 spots. It thus appears (hat the variation is in the diree(ion of (/«///w//^/A/. 

 The two species are of about the same size, (hough several ou( of the Iwentv- 

 seven autumnatu are larger than any of the seven hnndred and thirtv vcrnata

The pupa- of the two six-cies I have not myself studied. :\[r. Kiley 

 describes that of rernula (male) as pitted, the wiuiif-sheath extending to the 

 fifth abdominal ring, with the terminal spine simple; while the pupa of 

 aiilmmata (male) is not ])itted, is darker brown than renKtta, (he wings 

 reaching to the; si.xth abdominal ring, aiul with the terminal spine bifurca(e. 



The pupa of autumnata differs, ]Mr. Kiley states, in the same way as in 

 the male, bu( is lelatively stouter and more arched dor.sallv. and with a broad,
