Mr. S. Henshaw has kindly sent us for examination the three 

 specimens from the I.oew collection on which Osten Sacken based his 

 Cuban record of hcemorrhoidalis Fab. They prove to be our species. 



Since we characterized this species, two additional specimens of 

 the female have come to hand, through the kindness of F. W. Urich. 

 These show the red lateral tufts on the seventh segment, though less 

 pronounced than in the male. The red cilia occupy only the pos- 

 terior two thirds of the margin, while on the eighth segment they 

 appear to be absent altogether. Mr. Urich writes: "These Megar- 

 hini are so wild when they emerge, that they damage themselves a 

 great deal if not killed soon." We have also received two males of 

 this species from Bluefields, Nicaragua, through Dr. W. F. Thornton.

Mr. Theobald obviously redescribes our species, having indepen- 

 dently recognized that the continental North American form is not 

 conspecific with the one from Porto Rico.
