32 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I3I 



for homonyms and four species previously considered Neotropical 

 are shown to be probably or surely from other regions. Specimens 

 compared and agreeing with the types of i8i names (homotypes) 

 were brought back and will eventually be deposited in American 

 museums. Of the names treated, 189 appear to be valid, pending com- 

 plete information on the status of the earlier names of Wiedemann, 

 Thunberg, and some other authors: no are synonyms, and 40 are 

 homonyms — in a fair number of cases a name may be both. In a few 

 cases it was impossible to fix the status of a name owing to the condi- 

 tion of the type or uncertainty as to the material's being a true ty[)e. 

 For the sake of completeness a list is also given of the Walker and 

 Macquart species and a few others whose types could not be found — 

 64 in all. The Walker types are presumed lost, while some of the Mac- 

 quart types not seen by me are in Paris and others may turn up else- 

 where.
