in having the distal margin narrowly and very weakly emarginate 

 mesad, slightly thickened at each extremity of this emargination 

 and with a minute, elongate-conical styliform process situated in 

 •each, directed caudad. From the original description of Burr's 

 Psalis rosenbergi, it would appear probable that this condition is 

 also found in that species and that it is likewise a member of the 

 genus Spandex. 



^linute tubercles are found along the caudal margins of the fifth 

 to ninth dorsal abdominal segments, particularly in females, these 

 tubercles strongest laterad, from each of which springs a very elongate 

 hair.

The brief, longitudinal, rounded, dorso-lateral keels of the disto- 

 dorsal abdominal segment readily distinguish males of this insect 

 from the numerous other generally similar species of the Psalides. 



The present series averages smaller than the type series as 

 measured by Zacher ("Long. tot. 19-22 mm."), but no other features 

 to warrant specific separation appear to exist. Length of body, cf ,

Euborellia scudderi (Bormans).

We are not certain that these specimens represent scudderi, as 

 none of them have the wings showing. They are unquestionably 

 conspecific with the material from Para, Brazil, recently recorded, 

 with a question, as scudderi by Rehn.^ 



There is little doubt but that scudderi Bormans and Psalis burri 

 Borelli are referable to Euborellia, these species being, in fact, closely 

 related to Euborellia janeirensis. The present specimens, when 

 compared with males of janeirensis before us, are found to differ only 

 in the slightly heavier build, complete and rectangular tegmina and
