thirds from the base of the second cubital cell, second at one-third 

 from the base of the third cubital cell ; submedian cell longer 

 than median ; cubitus of hind wing originating just beyond the 

 transverse median nervure. 



Length 20 mm. 



Hab. Mackay, Q. ( Turner) ; Melbourne [French). 



In flavicornis 2 the three or four basal joints of the antenna? 

 only are yellow, the pubescence on the front is golden, the median 

 segment is slightly longer in proportion to the breadth, the head 

 and clypeus narrower, and the whole insect smaller and less stoutly 

 built ; the second recurrent nervure is received only just before 

 the middle of the third cubital cell, and the wings are darker at 

 the apex. It also occurs at Mackay, but does not seem to have 

 as wide a range as the present species. 



PSEUDAGENIA LUNULATA SaUSS. 



Pogonius lumdatus Sauss, Reise d. Novara, Zool. ii. Hym. i. 

 p. 58 (1867). 



IPompilus spectrum Kohl, Verb, zool.-bot. Ges. Wien, xxxvi. 

 p. 329 (1886). 



I think Kohl's name is probably intended for this species. He 

 states, however, that there is no transverse groove on the second 

 ventral segment, whereas in lumdatus it is distinctly visible, 

 though in some specimens almost hidden by the apex of the first 

 segment. The hind tibia?, though feebly spined, are much more 

 distinctly so than is usual in Pseudagenia, so that it can only be 

 placed in the genus with doubt. 



Cryptocheilus aureosericeus Guer. st. Australasia Sm. 



Mygnimia australasice Sm. Ann. & Mag. Nat. Hist. (4) xii. 

 p. 259 (1873), 2- 



The Australian form has the apical segment orange-brown 

 clothed with golden pubescence, but does not seem to differ 

 otherwise from Indian specimens.

Not previously recorded from Australia. Cameron's remarks 

 on this species are correct (Nova Guinea, vol. i. p. 55). 



Cryptocheilus commixtus, sp. n. 



2 . Clypeus more than twice as broad as long, very sparsely 

 punctured, slightly porrect, the apical margin transverse. Eyes
