margin and another posteriorly ; the base of the tegulae blackish. Fore- 

 wings creamy white, with large clearly defined blackish spots or patches 

 (varying in different specimens) ; the first near the base of the costa 

 extends obliquely outward and is narrowly connected along the extreme 

 margin with a large quadrangular costal patch, at one-third, reaching to 

 the fold and there connected at its inner angle with a small patch below 

 the fold ; near the base is a small triangular dorsal patch opposite the 

 first costal ; scarcely beyond the middle is a smaller quadrangular costal 

 patch, followed half way to the apex by an irregularly triangular costal 

 patch with serrate inner margin (its apex sometimes connected narrowly 

 with the terminal shading), between these two, but below them, is a 

 distinctly triangular patch on the lower angle of the cell, its apex reach- 

 ing nearly to the fold ; two smaller dentate dorsal patches tend obliquely 

 outward, the first about the middle, the second about the tornus ; a roundish 

 patch at the upturned apex of the wing is partly connected by scattered 

 scales with a less distinct diffused patch on the middle of the termen : 

 cilia white, tinged with fuscous on the middle of the termen, a fuscous 

 line running through their middle. Exp. al. 20-23 mm- Hindwings and 

 cilia rather shining, pale brownish cinereous. Abdomen and legs pale 

 brownish cinereous, the tarsal joints whitish, slightly spotted with brown."'

This is larger tlian the preceding species and quite distinct 

 from them in markings of the adnU moth, it being white with 

 black spots. These spots are larger in the females than the mal<>s. 



The larvae of this species feed in dead wood, particularly the 

 bark and outer parts of stems and trunks. The "hau" tree is a 

 great favorite with theml, but many other species are attacked as 

 well. Their presence may be known by the numerous black 

 pellets of excrement, which are to be seen on the outside of the 

 bark and in crevices, where they cling by the web which the 

 caterpillars produce in abundance. 



The eggs are white, about .5 mm. long by about as much in 

 diameter, cylindrical, rounded at the ends, a little larger at one 

 end on which is a circle of elongate spines bifid at tip, placed 

 close together; surface slightly corrugated. They are deposited 

 by the female in crevices and beneath loose pieces of bark, quite 

 a number in a batch. In some batches twenty-seven, forty-seven, 

 and fifty respectively were counted. They were quite regularly 

 placed, flattened somewhat by being crowded beneath the bark. 



The full-grown larva (Plate II, Fig. 11) is 25-30 mm. long, 

 of a dirty whitish color ; the head dark reddish-brown ; cervical 

 shield with a wide transverse blackish-brown band ; segment
