minor pectin. The claws are more slender and the pectin more 

 numerous than in the female. Genitalia; basal clasp segment long, 

 stout; terminal clasp segment as long as the basal, rather stout, 

 somewhat irregular and with a well-developed though inconspicuous 

 tooth apically; dorsal plate short, deeply and roundly emarginate, 

 the lobes well separated and tapering to a narrowly rounded, thickly 

 and coarsely setose apex; ventral plate long, broad, broadly and 

 slightly emarginate, the lateral angles rather thickly and coarsely 



setose; style rather long, stout, nar- 

 rowly rounded. Other characters as 

 in the female. Type Cecid. a 2504. 

 Paratype.— Cat. No. 19006. U.S.N .M. 



XENASPHONDYLIA, new genus. 



Antennal segments 14, subsessile, the 

 stem with a length about one-fourth 

 that of the cylindric basal enlarge- 

 ment. The palpi are long, quadri- 

 articulate, the claws simple, stout, and 

 about equal in length to the pulvilli. 

 Ovipositor as long as the body, the 

 basal portion fleshy, eversible, the dis- 

 tal part aciculate as in Asphondylia. 



Type of the genus. — Xenasphondylia 

 aTbipes, new species. 



This genus approaches Tetrasphon- 

 dylia KiefTer and Parasphondylia 

 Kieffer, from which it may be sepa- 

 rated by the distinctly more generalized condition of the antennae 

 and the more specialized ovipositor. 



XENASPHONDYLIA ALBIPES, new species. 



Female. — Length, 2.75 mm. Antennae extending to the fifth 

 abdominal segment, sparsely haired, basally yellowish, the flagellate 

 segments yellowish brown; 14 segments, the third and fourth free, 

 the fifth with a stem one-fourth the length of the basal enlargement, 

 which latter has a length 3 J times its diameter, with short, sparse 

 subbasal and subapical whorls of setae and numerous finer ones. 

 Low circumflli united on one face occur near the basal fourth and 

 subapically; terminal segment with a narrowly conical apical process 

 having a length about one-half that of the cylindric basal enlarge- 

 ment, which latter has a length three times its diameter. Palpi 

 long, the first segment irregular, the second with a length nearly 

 three times its diameter, the third fully one-half longer than the 

 second, more slender and the fourth three-fourths longer than the
