beyond apex, fifth indistinct distad, joining posterior margin 

 at distal third, its branch near basal third. Halteres pale yellow- 

 ish. Coxse yellowish brown. Legs pale straw. Claws moder- 

 ately long, strongly curved, unidentate. Pulvilli as long as 

 claws. Genitalia: Basal clasp segment rather long, stout; ter- 

 minal clasp segment nearly as long, moderately stout and dis-

 rowly rounded apex. 



Female. — Length, 1.5 millimeters. Antennae nearly as long as 

 body, brownish yellow, thickly haired; ? 14 segments, fifth with 

 a stem three-fourths the length of the cylindric basal enlarge- 

 ment, which has a length two and one-half times its diameter, 

 a moderately thick subbasal whorl of long stout setae, a subapical 

 band of long, slenderer setae and low circumfila, apparently anas- 

 tomosing and extending from basal fourth to apex of enlarge- 

 ment. First segment of palpi short, irregular; second with a 

 length nearly three times its width; third about two-thirds the

Genus HELIOLIPLOSIS novum 



The unidentate claws and the short triarticulate palpi show 

 an affinity with Kamptodiplosis, from which this genus is easily 

 separated by the structure of the ovipositor. 



Type of the genus, Heliodiplosis spatholobi sp. nov. 



Heliodiplosis spatholobi sp. nov. 



Female. — Length, 1 millimeter. Antennae nearly as long as 

 body, sparsely haired; 13 segments, fifth with a stem one-third 

 the length of cylindric basal enlargement, which has a length 

 twice its diameter, a subbasal whorl of moderately stout setae.
