gradually shading off distally, this browu scaling forming a band which narrows 

 costiid. Fifth abdominal tergite often with a distinct grey shade ; this grey scalinir 

 does not represent a mdiment of tlie white belt of .SV',s/rt tni)fah(x, etc., which is 

 situated upon the fourth tergite ; basal steruites also oft(ai distinctly paler than 

 the more distal segments. 



S. Tenth segment similar to that of (//■/■■<rii (PI. XLll. f \'2) ; tergite ending 

 in a short, blunt tooth ; it is apically not dilated exteruo-laterad as in jamaicrHsin 

 (compare PI. XLII. f. PS). Plarpe as m jamaici'nsis (PI. XLVII. f. fi) ; clasper 

 much narrower. Penis-sheath as \n jamaiceiisis, the number of tnliercles individually 

 variable. 



?. Vaginal orifice free, postmedian, slightly asymmetrical in jiosition, its edges 

 a little raised ; vaginal plate triangular, somewhat folded transversely.
