Remarks. IN THe cASe OF P. diminuta MALe, SINce THe SPecIMeN ReMOUNTeD BY PROF. WARReN T. ATYeO WAS INcOMPLeTe (LAcKING SeTAe h3, AND TARSUS OF LeG IV), A MALe FROM OTHeR SLIDe (43H8), MOUNTeD ORIGINALLY BY TROUeSSART, WAS DeSIGNATeD HeRe AS A LecTOTYPe AND USeD FOR ReDeScRIPTION. THIS SPecIeS WAS RePReSeNTeD BY A SINGLe FeMALe IN THe cOLLecTION (SLIDe 44A6), WITH FAURe MeDIUM cOMPLeTeLY cRYSTALLIZeD, THeReFORe THe ReDeScRIPTION OF THIS SPecIMeN WAS IMPOSSIBLe.
