which may vary to a streak more or less broken, running from 

 the anal angle for some millimeters toward the humeral angle. 

 In both wings the markings of the upper surface are dupli- 

 cated beneath. Expanse of primaries 47-52 mm. 



Note. — Since writing the following paragraph a female has 

 been bred bearing rows of fuscous loops on primaries and 

 secondaries situated as in the male. These loops are pale 

 brown in color.

 pair of short subdorsal transverse white lines, except last seg- 

 ment which is entirely white but for yellow or red-brown lat- 

 erals. Legs entirely white except claws. Wings white with- 

 out any markings above or beneath ; rub very easily, the prin- 

 cipal light brown veins often showing rather conspicuously.
