Genus KRONODIPLOSIS novum 



This peculiar genus is easily distinguished from all other bifili 

 by the unidentate claws and the uniarticulate palpi. Other dis- 

 tinguishing characters are given in the detailed description of 

 the species. 



Type of the genus, Kronodiplosis uichancoi sp. nov. 



Kronodiplosis uichancoi sp. nov. 



Male. — Length, 1.25 millimeters. Antennse probably one-half 

 longer than body, yellowish bronze, thickly haired; probably 14 

 segments, third and fourth apparently fused, fifth with stems 

 one and a half and one-half their diameters, respectively, the 

 basal stem being little more than a deep constriction of what 

 otherwise would have been a cylindrical basal enlargement, each 

 swelling with a moderately thick whorl of long, stout setse and 

 a circumfilum, the loops on basal enlargement extending nearly 

 to middle of distal enlargement and those on the latter almost 

 to apex of segment. Terminal segments missing. Palpi com- 

 posed of one broadly fusiform, sparsely haired segment. Eyes 

 large, black, confluent. Mesonotum nearly smooth and variable 

 yellowish brown. Scutellum and postscutellum yellowish brown. 

 Abdomen a little darker, thickly haired. Genitalia lighter. 

 Wings hyaline, subcosta uniting with costa at basal third ; third 

 vein just beyond apex, fifth at distal fourth, its branch at basal 

 third. Halteres yellowish, transparent. Coxae yellowish. Legs
