indicated also in Molnccaii ohlcmgomacidatus. In Iris 1\'. p. 71 0891) these 

 Saleyor sjiecimeus have been described as " var. leda" by Dr. Staudint;iT, who had 

 at that time overlooked that there was already a ledn Wall, and that the Celebes 

 form had already received the name of cefebensis in 18G.i, and the author gave as 

 chief character of his new " var. leda " the thickly black veins of the hindwings, 

 adding, however, that in one of his Saleyer males the veins are scarcely thicker Mack 

 than in ordinary. Moluccan individuals. In my Revision I treated that "var. leda 

 .Standing." as a synonym oi celebeiisis Wall, for the following reasons : — 



1. Wallace's description applies e.xactly to all those Saleyer specimens which 

 have the veins to the hindwings not unusually broadly black. 



2. Wallace's description gives the princijial character by which (dl the Saleyer, 

 and, according to Wallace, the South Celebes specimens (of course, as far as they 

 have become known to science), ai'e distinguishable from the Moluccan specimens; 

 whereas 



3. the characters by which T)r. Staudinger differentiates his "var. leda" are 

 found only in the greater numlier of the individuals, not, in all examples. 



4. A\'e know the Celebes form only from Wallace's description, and as this 

 description gives the chief distinguishing character of the Saleyer specimens, there 

 is no reason to regard the Saleyer specimens as subspecificallv different, until material 

 from Celebes proves this to be the case, though certainly tlie specimens with broadly 

 black veins form an interesting aberration. 



I objected to rename that aberration — the name of leda, was preoccupied — 

 since I consequently should have had to bestow names upon a great number of 

 aben'ations of other yellow Troides. 



In Jris VIII. p. 283 (]89(!) Dr. Staudinger renames his "var. leda," and calls 

 it thestiits. I hope it will be clear enough, from the above explanation, that the 

 black-veined thestius have to stand as aberrations of celebensis (Wall.), and not the 

 reverse, as Dr. Staudinger puts it. 



There are two collectors at present exploring Celebes, and it is to be hoiied that 

 they will succeed in procuring a series of specimens of celebetisis. 



The female from North Celebes (.Alinahassa) which Dr. Staudinger mentions. 

 Iris VIII. p. 283, and which he has been kind enough to lend me for inspection, 

 differs from the Saleyer females especially in the black upper- and underside of the 

 forewings, the latter being below marked with a lai'ge white patch near hinder 

 margin (before and behind submedian nervure), and bearing indistinct and rather 

 small white patches near the uervules iu the submarginal area; I'urther, in the diseal 

 yellow spots being somewhat shorter and the post cellular spot somewhat larger than 

 in i^aXeyer females, in the diseal cone-shaped black markings being obviously longer 

 and the submarginal yellow spots standing nearer the margin. 



Perhaps this female belongs to a North Celebesian subspecies of obtom/o- 

 maculattis. 



Staudinger, Lc, says, in respect to the names obloTigomacukdiis and heletM : 

 " Zum Schluss bemerke ich noch, dass, uach Rothschilds sehr griindlichen Unter- 

 suchungen, Helena Linnd die spiiter von Cramer als Pompeus beschriebene Art sein 

 soil, . . ." If my explanation about this matter (Nov. ZooL. II. p. 212) does not 

 prove that helena L. is the same as pom,peus Cram, (not "sein soil"), I am sorry to 

 say that I cannot add a word to my explanation, as to dilate any longer upon the 

 subject certainly would be a waste of words and time, and would not oi)en those eyes 

 which are kept closed.
