on segments 6-12; spiracles black, pale-centered; tuLercles "ii" 

 wider apart dorsally than "i," "iii" just above spiracle; 

 "iv-j-v" below spiracle, farther from it than ''iii" is. When 

 ready to pupate the larva eats a liole out through the pod ; then 

 spins quite a dense cocoon of whitish silk having one end near 

 the hole in the pod, so that the moth may readily make its exit 

 when ready to mature. 



The pupa is 6~10mm. long., by about 3mm. wide; medium 

 brown; dorsal surface of abdominal segments, beginning with 

 second, supplied with two transverse rows of very nmnerous 

 tiny, sliort, conical spines, those of the anterior row are the 

 larger; those of succeeding segments increase somewhat in 

 size going posteriorly ; cremaster obsolete ; wing, and antenna- 

 cases extending to apex of 3d abdominal segment, a free tip ex- 

 tending a little farther ; articulations between segments 3-7 

 movable. The pupal period is 10-12 days. 



Emarmonia sp. 



In July, 1907, I found a few larvae of this moth eating the 

 growing seeds of Canavalia galeata, a native species of bean 

 with a woody twining vine and very large pods containing 2 

 to 4 black beans about f inch long. The vine had been planted 

 by a fence in Honolulu and had gotten considerable of a growth, 

 and a few pods had already formed. As ihe vine continued to 

 grow and produce pods these larvae increased in abundance so 

 that finally nearly every pod was attacked by them. They 

 did not confine their attacks to the pods, however ; besides 

 feeding in the fleshy walls of the green pod and eating the 

 growing beans within, they also bored the peduncles of the 

 flower clusters, the petioles of the leaves, and the branches of 

 the vine itself ; practically attacking all parts of the plant. 



Quite a series of this moth was bred from the vine during 

 January and February, 1908. There is some little variation 

 in coloration as shown by the specimens exhibited. I find that I 

 have a specimen of this moth collected up Makiki Valley in 

 May, 1908, which is the only one I had previously seen. 



The eggs are laid on the surface of the bean pod, singly or 

 one or two together in slight unevennesses of the surface. They 

 are irregularly oval, about half a mm. long; flattened below, 

 slightly convex above and finely reticulate ; whitish in color.
