Hymenoptera. 165 



tibiiu and femora opaque, absoletely punctured ; the tibiae 

 channelled. 



A larger species than O. Westzvoodi, Dbm. differing 

 from it otherwise in the front not being rugosely punctured 

 and bearing three distinct longitudinal keels, the lateral 

 keels, too, projecting more ; in the sides of the pronotum 

 being more strongly striolated ; in the tegulse being 

 black, and the nervures whitish ; and in the abdomen 

 being longer, the petiole especially being as long as the hind 

 coxae, while in O. Westwoodi it is not half the length. 



As bearing on the distribution of OnycJda^ I may remark 

 that Mr. J. J. Walker, R.N., has taken O. notata, Fonsc, at 

 Benzus Bay, Morocco.
