Type locality. — "Santo Domingo" (=Dominican Republic). 



Types. — Holotype in the United States National Museum (No. 

 26346) , collected by August Busck. (The recorded paratype is now 

 the type of O. cube7isis Blackwelder.) 



Records. — The following are the records known to me : 



Kispaniola: Dominican Rf.pubi.ic (Notman, 1925; U.S.N. M.) ; Haiti, La Visite 

 (Darlington, 1937; A.M.N.H.), KeuskcfE (Darlington, 1937). 



Specimeiis examined. — I have seen only the type and one of the 

 specimens collected by Dr. Darlington at La Visite. 



Remarks. — The paratype that Notman designated was from Cuba 

 and is believed to be a distinct species. It is herein described as 

 cubeiisis new species. Darlington has collected nine additional spec- 

 imens of this species in Haiti.
