Panama, the larvse in ground pools. In the monograph, Mr. 

 Knab, at the last moment, placed punctimacula with apici- 

 macula on his own responsibility. I agree with him in the re- 

 duction by one of the number of species, but I' think that the 

 single type of punctimacula is clearly a malefactor and not an 

 apicimacula.
