young or half-grown cucumbers, often doing much damage, is also 
said to occur here, but we did not obtain specimens. The larvz also 
bore in melons and squashes, like those of the preceding species. 
Sweet-potuto Pire-worm. (Hymenia fascialis.) Figures 138, 139. 
According to the notes of Miss Victoria Hayward the Sweet 
Potato vines in midsummer are often very badly damaged by the 
green larvee of a small pyralid moth called the “fireworm.” It eats 
out the parenchyma, quickly reducing the leaf to a skeleton. 
Some of these larvee which were mailed to me by her at Bermuda, 
August 8th, had become pup when they reached me, August 12th ; 
on the 13th the imago emerged from one of them. Thus the dura- 
tion of the pupa stage may be as short as four or five days.

This small moth is rather prettily marked. The ground-color of 
the body and wings above is coppery-brown, with white markings ; 
front of head and a ring behind the eyes white ; abdomen crossed 
by five or six bars of white, the two anterior wider; under side 
buff, with three rows of black spots. Both pairs of wings are 
crossed by a nearly median bar of white, which, when the wings are 
folded, runs directly across in a straight line, coincident with the 
basal white bar of the abdomen, but does not quite reach the costal 
margins of the fore wings, ending in a point, with a subterminal, 
angular, hook-like projection, directed backward ; midway between 
this white bar and the apex of the wing is a white transverse spot, 
bordered with black, and reaching the edge of the wing, with a few 
specks of white at its inner end, and a blackish patch beyond it ;
