 Hah. Brazil {Noel). 



Erephrosis hasalis, ? , Walker, List Dipt. pt. i. p. 133 (1848). 



The type is in very bad preservation. The palpi are long 

 and slender. 



Hab. Brazil {Mornay). 



Erejihrosis basalis, var., ? , Walker, List Dipt. pt. v. Suppl. 1, 

 p. 322 (1854). 



This is most probably a distinct species, the palpi being 

 quite different in shape from those of hasalis, which are long 

 and narrow ; these have the second joint broad and concave, 

 ending in a point, light red, with sides and tip black ; the 

 proboscis is much shorter and the wings clearer. Another 

 jemale specimen, labelled in Walker's handwriting as hasalis^ 

 resembles this variety, having the same palpi. The variety 

 and the type are in too poor preservation to distinguish other 

 differences between them. 



Hah. R. Tapajos, Brazil, Amazons {Bates).
