The aeeount <d this genus which I published 111 I'.Mt was based mainly on the 

 e.\:tmiiiation of sjierimens from Continental Asia. 1 had, it is true, receiveil a few 

 siHM'imens from the Arrhipelago ; and I was able to make a hurried examination of the 

 name<l collection in Berlin. But I had had no opportunity of examining a large and 

 representative collection at leisure, an opportunity which has now been aflfortle*! by the 

 obtaining of the Van de Poll collection for the Indian .Museum. 



The careful examination of this additional material convinces me that the drastic 

 reduction in the numl>er of ,spec4es, advcK-atetl in my previous paper, was fully ju.stitie<l 

 f\< ••|it in the case (d /,. fmrhirauda. Zang ; and. indcetl, that a few further retluctions must 

 In- iii.iile. Thus L. nltluvidnis proves to be a synonym of A. hi col or ; and L. unraajuitteae, 

 together with the names regardetl as .synonyms with it. are almo.st certainly .synonyms of 

 the Mime .spe«ie>, or partiv «d the same species and j>artly «d L. dnitalus. 



I have seen nothing in the collection that can be distinguishetl as L. mnro*«iri>w*»jr ; 

 but n specimen laU'lled with this name, and a.sso<iated with specimens both «d /.. /»»ro/<>r 

 anti A. drntaluii, proves to lielong to the former s]>ecies. I am still inclined to think, judging 

 fronj Sthaufu.Hs's ilescription. that the type may prove to be of n distinct species, the 

 puncturing of the head Iwing apparently much coarser than in /... hicolor. and the c<«nvexity
