segment is attached, the distal lobe being broad, broadly rounded 

 and thickly setose, terminal clasp segment subapical, short, stout, 

 somewhat curved, strongly chitinized and unidentate apicad; 

 dorsal plate moderately long, broad, deeply and triangularly 

 emarginate, the lobes rather thickly and irregularly rounded and 

 margined with rather sparse, stout setse; ventral plate moder- 

 ately long, broad, deeply and narrowly incised, the lobes rather 

 broadly rounded and sparsely margined with coarse setse. Style

 than the body, reddish brown, sparsely long-haired ; 14 segments, 

 the fifth with a stem one-fourth the length of cylindrical basal 

 enlargement, which has a length about three and a half times 

 its diameter, a sparse basal whorl of rather stout setae, a broad 

 subapical band of longer, slenderer setse, and low circumfila 

 at basal fourth and apicad. Segments progressively somewhat 

 shorter, twelfth with a length a little over twice its diameter, 

 thirteenth with a length one and a half times its diameter, and 

 fourteenth with a length a little greater than its diameter. 

 First segment of palpi subquadrate, second rather broad with 

 a length about two and a half times its diameter, third as long 

 as the second and slightly dilated. Mesonotum dark yellowish 

 brown, the yellowish submedian lines sparsely haired. Scutel-

Luzon, Laguna Province, Los Baiios and Mount Maquiling, 

 1917, College of Agriculture accession No. 18315 (L. B. Ui-

 from leaf galls on Symphorema luzonicum F. Vill. 



Genus DICEROMYIA novum 



Allied to, though easily separated from, Zalepidota Riibsaamen 

 by the greatly produced tapering spurs or horns at distal angles 

 of terminal clasp segment. The subcostal cell is not remarkably 

 broad. The female is unknown, but the characters of the male 

 abundantly justify the above association. 



Type of the genus, Diceromyia vemonim sp. nov.
