having been examined by Burr and designated as "type." If 

 the Venezuelan specimen shows the different type of pygidium 

 described and figured bj^ Burr it certainly does not accord with 

 the original description. In the case of confusus it is evident to 

 us that the Colombian material examined by Burr is not specifi- 

 cally identical with the typical Paraguayan specimens of Borelli. 



Labia ciirvicauda (Motschulsky)

Para, Para. (C. F. Baker.) One male, one female. 

 These specimens fully agree with individuals from Long Key, 

 Florida. Aside from the present record, the only one we can find 

 of the occurrence of this circumtropical species on the mainland 

 of South America is that of the synonymous Labia glahricula 

 Kirby, from Santarem (Kirby) and Sao Paulo (Burr), Brazil. It 

 seems desii-al^le to call attention to the fact that the key for the 

 genera of Labiinae given by Burr^ would run this species to 

 Chaetospania or Sphingolahis, the head in this species being sub- 

 sinuate caudad when compared with L. minor, the genotype, which 

 is in the alternate category. Apparently this feature is not of 

 generic value in the present instance, as curvicauda is congeneric 

 with minor.

This specimen is referred tentatively to the present species, 

 the exact relationship of which to certain of the other forms of 

 the genus is not at present clearly understood. However, our 

 individual fully agrees with Kirby 's description except that there 

 are no blackish markings on the head or pronotum. 



Borelli has reported this species from Tacuru Pucu, Paraguay 

 and San Pedro, Misiones, Argentina.
