No. 2361. DESCRIPTIONS OF NEW SAWFLIES—ROHWER. 91 



which is omitted is scita Konow. Specimens of a species which 

 agrees with Konow's description of scita and were determined as that 

 by Enslin are at hand but they belong to the genus Arge. Whether 

 scita was wrongly placed by Konow or not can not be determined 

 from the information at hand, and a comparison of the type will 

 probably be necessary. The following tabulation is based on females. 



KEY TO CERTAIN SPECIES. 



1. Postocellar and ocellocular lines subequal 2 



Postocellar Hue distinctly longer than ocellocular line 3 



2. Basal part of wings clear; a distinct dark brown spot below stigma, and apex of 



wings faintly brownish macidipennis (Cameron) . 



Basal part of wings brownish; no distinct cloud below stigma, although this area 

 is somewhat darker chinensis, new species . 



3. Winga uniformly dark brown melanoptera, new species. 



Wings with at least basal and median cells subhyaline 4 



4. Body purplish; ridges of middle fovea very prominent, especially opposite anten- 



nae; eyes distinctly reniform, converging' below poecilotricha (Konow). 



Body greenish -blue; ridges of middle fovea less strong; eyes hardly reniform or 

 converging below - .janthina (Klug). 



CIBDELA MACULITENNIS (Cameron). 



Konow considered this to be synonymous with janthina (Klug), 

 but later Enslin expressed the opinion that was a good variety. If 

 the determination for the material before me is correct, I believe 

 muculipennis to be a distinct species. 



CIBDELA CHINENSIS. new species. 



In general appearance more like poecilotricha (Konow), but easily 

 distinguished from that species by having the postocellar and ocel- 

 locular lines subequal ; on this character it falls next to maculipennis 

 (Cameron), but differs from that species by the darker wings. 



Female.— Length, 9.75 mm.; length of anterior wing, 9.75 mm. 

 Anterior margin of labrum depressed, truncate; anterior margin of 

 clypeus not depressed, gently, arcuately emarginate; supraclypeal 

 foveae deep, short oval; lateral walls of middle fovea slightly con- 

 stricted above antennal foveae, not extending below antennal foveae ; 

 inner margins of eyes only slightly converging below; postocellar and 

 ocellocular lines subequal; postocellar furrow complete, not sharply 

 defined; postocellar area parted by a median, impressed line; third 

 cubital cell shorter, on both radius and cubitus, than the second; 

 stigma broadest at base tapering to apex. Metallic with distinct 

 purplish tinge; with the usual whitish pubescence; anterior wings 

 pale brown with the area below the stigma darker; posterior wings 

 subhyaline; venation blackish. 



In the paratype the antennal furrows above the supraclypeal 

 fovea are deep, and the second and third cubital cells are nearer the 

 same length. 



Type locality. — Hongkong, China.
