One female collected, 1911, by F. W. Terry. Also one female 

 paratype collected by H. R. Caldwell at Foochow, China. 

 Type. — In the British Museum of Natural History. 

 Paratype.— Cat. No. 22357 U.S.N.M. 



CIBDELA MELANOPTERA, new species. 



In size and appearance more like poecilotricJia (Konow), but the 

 darker wings will readily distinguish it from that species. 



Female. — Length, 10 mm.; length of anterior wing, 11 mm. 

 Anterior margin of labrum depressed, slightly emarginate; clypeus 

 flat, the anterior margin distinctly arcuately emarginate ; supraclypeal 

 fovea deep, elongate oval; walls of middle fovea parallel, prominent, 

 especially opposite antennae, extending somewhat below ventral 

 margin of antennal foveae; eyes reniform, slightly converging below; 

 postocellar line distinctly longer than ocellocular line; postocellar 

 area feebly defined laterally, not parted; postocellar furrow distinct, 

 angular anteriorly; stigma below nearly straight for half its length 

 then distinctly tapering; second and third cubital cells subequal or 

 radius. Metallic with a distinct purplish tinge; pubescence on top 

 of head and thorax blackish, the rest whitish; wings (anterior and 

 posterior) uniformly brownish; venation blackish. 



The paratype has the basal part of the hind wings paler. 



Type locality. — Iligan, Mindanao. 



One female from C. F. Baker. Also one female paratype from 

 Mount Merinjak, altitude 2,200 feet (about 66 meters), May 29, 1914. 



Type.— Cut. No. 22358 U.S.N.M. 



Paratype. — In the British Museum of Natural History. 



CIBDELA POECILOTRICHA (Konow). 



Syn. Cibdela pruniosa (Cameron). 

 The specimens determined as this species agree well with Cameron's 

 description of pruniosa, and there seems to be but little doubt that 

 they are his species. They also agree with Konow's description of 

 poecilotricJia, but this description does not include sufficient characters 

 to enable one to feel sure of the correctness of the identification. 

 Konow has, however, synonymized pruniosa with poecilotricJia, so I 

 have used his name and accepted the synonymy. 



Family TENTHREDINIDAE. 



Subfamily Diprioninae. 



NEODIPBION (NEODIPRION) EXIMINA, new specie*. 



This species is closely allied to abbotii Leach, but is readily sepa- 

 rated by the black tergum and scutum. 



Female. — Length, 6.5 mm. Clypeus gently convex basally, with- 

 out sculpture, apical margin narrowly depressed and broadly, 

 arcuately emarginate; supraclypeal foveae unusually prominent;
