The early specimens of this interesting species were those sent by 

 McLeannan, who collected it in company with Galbreath somewhere 

 on the Caribbean slope along the line of the Panama Railroad. The 

 two specimens concerned, male and female, are in the U. S. Na- 

 tional Museum, but as usual with this older material have no 

 definite locality noted on the label. It is probable that they were 

 obtained on the Rio Chagres.
