always identical in their minor details in different specimens, nor some- 

 times on both wings in the same specimen. Beyond the cell there is a 

 transverse continuous line, broader than the rest and outwardly bent over 

 median nervules. The ground color is blackish over nearly two-thirds 

 of the primaries from the base, and outwardly gray. Hind wings rounded 

 in both sexes, with blackish hairs at base, pale and sub-pellucid, with 

 short gray fringe, before which there is a narrow blackish edging. The 

 abdomen is blackish. The males are smaller than the females. The 

 smallest male expands about 40, the largest female over 60 millimetres. 



A female, after being captured and pinned, deposited three eggs, which 

 were clothed with scales of the same color as those of its abdomen. 

 The females possess a long ovipositor, with which they place their eggs 

 securely in the deep crevices of the bark of the same species of tree 

 from which they emerge. In due time the worms are hatched, and although 

 very small, are soon able to bore into the tree, never apparently ceasing 

 to eat and extending their tunnels through solid wood, first in the alburnum 

 and then through the heart, their burrows increasing in size as the larva 

 increases, until the latter are completely grown. In consequence of the 

 innumerable tunnels cut in feeding many trees. are destroyed.

LAVERNA.

Miss Murtfeldt favors me with the following notes upon the larva of 

 this species : " It feeds in the flowers of the (Enotheras both wild and 

 cultivated, and is especially destructive to (E. Missouriensis, which is now 

 extensively cultivated. The eggs are laid singly on the sticky surface of the 

 calyx, and the larva;, as soon as hatched, make their way to the centre of 

 the bud and feed upon the petals and stamens. The full-grown larva is 

 % inch in length, cylindrical, tapering slightly posteriorly and anteriorly.
