portions in the paratypc. Wings transparent, iridescent, tinged with mummy 

 brown, area of costal veins and distal areas toward appendicular field mummy 

 brown in type, prout's brown in other specimens, except area of swollen portions 

 of costal veins which is whitish; appendicular field heavily tinged with mummy 

 brown in type, prout's brown in other specimens. Ventral surface pale ochra- 

 ceous-tawny, with abdominal segments narrowh" margined with ochraceous-bufT. 

 Limbs ochraceous-buff. 



The allotype is clearly a recessive example and has the tegmina immaculate. 



In addition to the type and allotype, we have before us a para- 

 typic male, taken at Cabima, Panama, May 21, 191 1, by A. Biisck.

The series of adults differs from the majority in a Mexican series 

 before us, in having the tegmina more suffused with brown between 

 the veins, except toward the costal margin. Some variation in this 

 respect is, however, shown by the Mexican series. 



The male sex has relatively short stout styles with interval be- 

 tween their bases relatively broad, the dextral style having beneath 

 its base sinistrad a pair of microscopic dccurvcd teeth. The margin 

 of the subgenital plate appears to be somewhat irregular and sub- 

 ject to some indi\idual variation. 



Our recent remarks on this si)eciesi''^ can not be supplemented 

 until much larger series are secured. 



The large immature examples before us are pale and immaculate 

 ochraceous-tawny dorsad, except that the abdominal segments are 

 marked with microscopic and rather distant flecks of ochraceous- 

 tawny, while at the latero-caudal angles of the fifth segment are 

 large blotches of mummy brown, the sixth segment being lined at 

 that point along the caudal margin with the same color.
