 i'uretarsns about three times as long as broad, armed with three long spines, second 

 segment with one long ajiical spine ; midtarsus generally with two or three long 

 bristles indicating the comb ; first segment of mid- and hindtibia shorter than the 

 four others together ; long apical spur of hindtibia not half the length of the first 

 tarsal segment ; no spines on the upperside of the tarsi ; jiaronychinm jn'esent, 

 the lol)e long but very slender ; no pulvillns. Spinulatiou of abdomen weak. 



Early stages not known. 



Hab. Southern Neotropical Region. 



Tlie genus is a dwarfed offshoot from Protojmrcc, parallel with the series 

 CIdaenogrammn — Ceratomia. It has aei[uired, like Geratomia, the short and 

 Strongly armed foretarsns, lost the pulvillns, and preserved the unarmed tibiae. 

 The presence of some long bristles indicating the comb on the midtarsus proves 

 Xeogene to have branched off' independently of Chlaenogramma, in which the comb 

 18 entirely reduced to the ordinary spinulatiou, while in the modification of the 

 bristles of the pilifer into scales JS'eogene is even more advanced than Ceratomia, 

 which has the normal brush of bristles. It belongs to the Nannoparce branch, 

 forming a more specialised member of that series, which terminates in the 

 Australian Coenotes.
