PALMACORIXA new genus. 



Elongate, with vermiculate semi-obsolete markings. Male 

 palae thin, platelike, obliquely inserted, the height about one- 

 half the greatest length, the upper margin parabolic, the strid- 

 ulating "pegs" in two rows and reduced to the lower proximal 

 corner of the inner surface. Large stridular area on femur. 

 Female palae short cultrate, femur also apparently with a strid- 

 ular area. No terminal palar spine in either sex. Male vertex 

 tumid, face flat, hardly foveate, female face convex. Meta- 

 thoracic wings aborted in both sexes. Male asymmetry and 

 strigil dextral ; fifth tergite entire, sixth divided. Perhaps re- 

 lated to Arctocorisa Walleng. but differs, markedly in several 

 particulars from any other genus hitherto described. 



Palmacorixa gillettii new species. 



Head pale yellow, vertex usually carinate, posterior angles rather 

 acute and produced backward. Posterior margin emarginate. In-
