52 PROCEEDINGS OF THE NATIONAL MUSEUM vol. U6 



Type locality. — "Castro, Parana, Brazil." 



Additional type data. — Originally described from tliree males 

 and two females, no single specimen of which was stated to be "the 

 type" in the original description. All five of these specimens are 

 therefore syn types (article 73, paragraphs b and c. International 

 Code of Zoological Nomenclature, adopted by XV International 

 Congress of Zoology, London, 1961). Two of these syntypes bear 

 the USNM type number assigned by Dyar: 10921. In addition, one 

 of these two specimens bears a written label containing the word 

 "type" in Dyar's handwiiting. I hereby designate this specimen as 

 the lectotype and have so labeled it (USNM type 10921; collection, 

 William Schaus; & genitalia slide WDF 1533). 



Location of type. — United States National Museum.

 Janeiro.

 gin of upper surface near anal angle.

Male genitalia as characterized in key and as illustrated by figure 4, 

 shows close relationship to draudti and laudamia. From both species 

 it differs greatly in form and shape of cuiller and aedeagus.
