I have refrained from giving a kej- to the inchidecl forms because 

 the numerous species described b}^ Blanchard and Pliilippi are abnost 

 certainly a mixture of several genera, and until more of these species 

 are rediscovered it would be foolhardy to attempt a key in this group. 



I am including in Limnophila the species described as Polymoria 

 Philippi. The only species I have ever seen, P. lutea, is represented 

 by a single legless specimen, and I am unable to decide as to whether 

 or not this insect has spurred tibia?.
