We described this species from a male found by AVeiske on the upper part of 

 the Aroa River. A. S. Meek has obtained five more 6 3, but no ? . The insect 

 lielongs to the present genus. 



8. Platypthima decolor sjiec. nov. 



Though this species is rather different from the three others of the genus, we 

 do not think it necessary to separate it generically from them.

 behind eye creamy ; tibiae and tarsi more or less clayish ; femora, breast and 

 underside of abdomen clothed with olive, clay, and grey hairs : palpus and foreleg
