The labruni resembles that of 0. falht.r, etc., in respect of 

 its only slight projection from the perpendicular front face of 

 the head hui differs by its much larger size which may be 

 expressed as follows : — Looking (from in front) at the front 

 face of the head one sees the outline of the clypeus as an arc 

 of a circle the altitude of which is evidently greater than the 

 distance from the vertex of the labrum to the vertex of the 

 perpendicular front face of the head, while in fallaa% etc.. the 

 corresponding altitude occupies a very much smaller propor- 

 tion of the front face of the head. The extremely coarse punc- 

 turation of the dorsal surface prevents the confusion of this 

 species with any other Ocnodvs known to me.

DiPHYLLOCERA. 



D. kirhyana, White. Burmeister has drawn attention to 

 the fact that the antennal flabellum of this species consists of 

 five lamellce according to White and of six according to Erick- 

 son. In the male there are six lamellae of about equal length, 

 while in the female the basal lamella is so short that its 

 being in reality a joint of the flabellum might easily be over- 

 looked. As White describes the male it is clear that he either 

 counted incorrectly or had before him a species unknown to 

 subsequent authors and distinct from that which has since 

 borne the name kirhyana. 



Pachygastra. 

 In my tabulation of the Australian Sericoid genera (loc, 

 cit.) this genus is distinguished by the form of its front tibias. 

 It should be noted that I have described, above, a new species 

 under the name calorata having front tibiae not much different 

 from those of Pachygastra but which certainly cannot be re- 

 garded as a member of that genus. I have placed it in 

 FrencheUa.
