96 BULLETIN 182, UNH^ED STATES' NATIONAL MUSEUM 



Ty'pe locality. — "Amazone: Pebas (de Mathan). Antilles: Saint- 

 Vincent (Smith).'' 



Types. — Presumably in the collection of Blanche Kancin, Caen, 

 France. 



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



St. Vincent: (Fanvel, 1904; British Museum), 

 South America: Brazil (Fauvel, 1904). 



Specimens examined. — I have examined 10 specimens in the British 

 Museum and borrowed 2 of these for further study. 



Remarks. — The specimens in the British Museum are undoubtedly 

 part of the series from which Fauvel's examples came. I have ob- 

 served in this series that the median tooth of the front of the head 

 in the male varies greatly in size. 



I find no record of the liabits of this species.
