THE LEPIDOPTERIST 



13 



Mr. L. Trouvelot, who was an accomplished entom- 

 ological artist, did not "carelessly allow the moths 

 to escape through an open window." Some of the 

 cocoons were blown out of the window and M". 

 Trouvelot, when the loss was discovered, not only 

 searched diligently for the missing cocoons but ad- 

 vertised the loss in the American Naturalist and the 

 local papers. Plate III.

Primaries, upper surface, differ from typical form 

 as follows: the black bar running along the costal 

 margin is broadened as a suffusion posteriorly over 

 the anterior half of the discal cell. It also is ex- 

 tended outward toward the apex, entirely obscuring 

 the white of the subcostal area. This suffusion re- 

 sults in a partial obliteration of the white marginal 

 spots, and a marked blurring of the white submarginal 

 area between the discal cell and the apex. The under- 

 side of primaries show all the suffused areas carried 

 through but to a lesser degree. The white marginal 

 spots are not involved, however, in this suffusion. 



Secondaries, upper surface shows a slight tendency 

 for the dark venation to carry through from below, 

 along the marginal area, this feature varying a little 

 in the two specimens before us. The under side of 

 secondaries show a tendency for heavier lineation of 

 of the nervules.
