filled up with brownish, tlotted, as is the base, with bluish scales. The sec- 

 ondaries are clear chalk-white, not creamy, as in A. dii'a. The marginal 

 band is broader and more even on its edges than in that species, and the base 

 of the wing is more densely filled up with black. Beneath the ground color 

 is wholly pure clear white, and not yellowish, as in A. diva. On'the apical 

 margin of primaries is a heavy blackish patch containing a series of six sagit- 

 tate, bluish white spots; before this the white band of the upper side is re- 

 peated with a small black linear and one roundish discal spot, and then a 

 blackish band widest on costa. The base is white, with a bluish tinge. The 

 secondaries have the marginal band of the upper side repeated with small 

 bluish white patches, while the base is marked by a bluish white cloud, en- 

 closed by black hairs, broadening into a spot on the costa. The thorax above 

 is concolorous with the base of the wings. Abdomen brown at base, becom- 

 ing gradually white towards the tip, the segments being indicated by narrow- 

 white bands. Below, the thorax, abdomen, legs and palpi are clear pure 

 white. Average expanse of diva, ten examples, 17 mm.; casta, ten ex- 

 amples, 21 mm.

There is no doubt as to distinctness of this species. The col- 

 lection contained many specimens of A. diva for comparison, and 

 though resembling each other, it would be impossible to confound 

 the two forms. 



Euclidia annexa n. sp. — Primaries slate-brown. A little before the middle 

 begins a brown mark which is remarkably like that in the well-known E. mi 

 of Europe. It is almost even on its anterior edge, scarcely touching the in- 

 ternal margin, but there slightly rounded and curving upward into a deep 

 tooth in the middle, broadening along the course of the median nerve and 

 running up to costa, where it is joined by another longitudinally-oblong brown 

 patch not reaching to the internal margin. These patches are bordered by a 

 pale line, and in the larger patch is a distinct black dot. On the costa sub- 

 apically is a greenish brown patch, and the external margin is also brownish, 

 with a paler anterior shade. The secondaries are dusky slate color, with two 

 very distinct ochreous waved bands, and a patch of the same shade in the 

 middle near the costa, enclosing a brown discal spot. Abdominal margins 

 dusky. Underside wholly pale ochreous, with the margins, two waved bands, 

 and discal marks brownish black. Thorax and abdomen above wholly brown- 

 black, except the tip of the latter, which is ochreous. Beneath wholly ochre- 

 ous. Expanse of wings 30 mm.

It has been claimed that "sugar" is not attractive to moths in 

 tropical countries, and that quite different bait must be used. Dry 

 codfish and other strong smelling substances are used with success, 

 and recently I learned of quite a novel attraction ; it is simply the 

 collector's shirt that he has had on all day when hard at work and 

 which is said to be rather superior to anything else as bait.
