One male labeled Spathipalpus macuUventris, from Bahia. This 

 is not a type, but agrees perfectly with Rondani's excellent descrip- 

 tion, quoted by me in the reference above. As there stated, I think 

 Spathipalpus Rondani is an entirely different genus. The United 

 States National Museum still contains only the single female of 

 jnuGuliventns that was mentioned by me. As compared with the 

 Vienna male, the former has the palpi decidedly more clavate; in 

 the latter they are of uniform diameter, very slender, projecting 

 forward beyond the epistoma to a distance equal to fully three- 

 fourths the vibrissal axis of the head; they reach almost to the 

 middle of the exposed part of the proboscis when it is directed for- 

 ward as in this specimen. The proboscis, except at base, is covered 

 with minute erect hairs. The ocellars are minute, in the female 

 spreading almost laterally, in the male somewhat more proclinate. 

 The male has no orbitals, a point left a little in doubt by Rondani's 

 statement that there are two rows of frontals. He evidently included 

 both sides. 



Length of male, 6.3 mm ; of female, 7 mm ; Rondani gives 7 mm.
