median space is shaded with brown, the tint beeomini; obvions below 

 the reniforin. Oibicnlar wanting- in the specimen. Keniform hirge, 

 oval, brown, with a- blackish delining line. Secondaries more luteons, 

 paler basally, w ith a feebly marked, dusky extra median line, an irreg- 

 nlarly dentate, pale subterminal line, preceded by darker-brown S]>ots, 

 and a narrow, black, interrupted terniinal line. Beneath, all wings 

 with adiscal lur.ule, a dnsky extra median line, and a pale subterminal 

 line, which is preceded by a darker shading.

A single specimen only, from the United States National Museum, 

 ''Collection C. V. Kiley." The species very strongly resembles Z. kvvi- 

 (jata in general a])pearance, and with this it was associated in the 

 Museum collection, though with a query. The specimen is defective 

 and badly mounted, but seems to have been bred, and bears the number 

 "2585, April 17, '82." 



It is readily distinguished from Z. hvvUjaiti^ which it most resembles 

 in superficial appearance, by the uneven transverse anterior line and 

 by the characteristic, lunnlate, pale subterminal line, emphasized as it 

 is by the prominent preceding black spots. 



The antenna' of the male do not differ in any essential feature from 

 those of Z, hrvu/aia. and there are two modified joints, with rather evenly 

 curved stout spines, while the curve or bend in the antenna below the 

 scaly thickening is slight. 



The forelegs differ very decidedly, however, and first in the relative 

 length of the trochanter, which is proportionately very much shorter 

 and does notecpial one-fifth the length of the femur. The tuftings seem 

 to be much the same in character, but are much less prominent, the hair 

 much less scalelike and not so much enlarged at the tips. The enlarge- 

 ment of the tibial process is much less evident, and indeed the entire 

 foreleg is very decidedly shorter.

" Pale, testaceous, brownish. Primaries crossed by three black, broad, 

 distinct lines. The transverse anterior even, per]»endicular, broad. The 

 transverse ])OSterior narrow superiorly, exserted slightly beyond the 

 disk, where it is slightly medially notched, more broadly marked below 

 the subiiiedian nervure, even. Subterminal line very broadly black, 

 the subterminal s]>ace deepening in color to the line, followed by a very 

 pale shade (as are the first two lines), even, a little inwardly arcuate, 

 arising on costa before apex and reaching the internal margin within 

 the angle. Terminally the wing is darker, more brownish. Hind 

 wing a little paler, crossed by two ill-defined darker shade bands. On 

 ]trimaries a relatively large, rounded, black discal spot in the place of 

 the reniform. Beneath i)aler, with double common lines, the subter-
