almost exactly like ehalyhca^ of which I have examined the 

 typo, a tbmale from Celebes. C. chalyhea has the ocelli lar^e 

 niul fulvous (as also have C. aptcaUs, (^ , and C. ievminalifi)^ 

 but in vaijans they arc black and more ur less aborted, espe- 

 cially the lateral ones. C. chaiybea has two widely separated 

 dentiform processes on labrum just below clypeal mar^^in, but 

 these are absent from C. vaijans^ C. apicah's, ^ , and C. tenni- 

 nalin. C. cliaJybea has the face considerably broader below, 

 and the abdomen less decidedly purple than in C. vaganSy 

 but these dif^Vrences are ])robably sexual.

Ashmead, in his recent list of Philippine Ilymenoptera, 

 does not cite any species of Ctenoplectra. The genus has 

 hitherto been known from Burmah, i\lalacca, Celebes, and 

 Natal. In C. apicolis, ^ , the ajiex of the abdomen is pro- 

 longed into \on'^ processes laterally, but in C. vai/ans the 

 processes are quite short, and the apical projection is more 

 pointed. 



C termtnalvt, Sm., from Natal, is remarkable for the 

 brilliant blue of its abdomen.

l)ilTers from J/, bicolor thus : — Abdomen piceous, broad 

 hind margins of the segments and most of tilth segment dark 

 rufous ; fimbria dull white ; marginal cell shorter and broader; 

 niesothorax shining, with well-separated or scattered punc- 

 tures of various sizes; clypeus shining, smooth in middle, at 

 sides with some rather large punctures (in bicolor it has 

 large well-separated punctures all over) ; supraclypeal area 

 also shining. Long tongue and hairs on tibiie (long and 

 curved) as in bicolor. tScutellum with a median shining 

 impunctate space ; nietathorax coarsely rugose at extreme 

 base only ; ventral surface of abdomen ferruginous clouded 

 with fuscous, hind margin of iirst segment shallowly 

 emarginate.

In the interleaved copy of the Cat. Ilym. B. 3Ius. in the
