MALLOriiAGA FROM BIRDS OF THE PONAPÉ I. ETC. 485 



3. The oval emargination in 

 front of the frontal margin is bound- 

 ed all around by a broad chitin- 

 ous band, which, in P. australis, 

 bounds only the posterior margin 

 of the emargination. 



4. Eye with a very fine 

 spine instead of a hair. 



5 . Antennae somewhat shorter 

 and broader. 



6. The inner row of hairs on 

 the metathoracic border contains 

 two hairs instead of three. 



7. The first abdominal seg- 

 ment much narrower, bringing 

 about a distinct constriction be- 

 tween metathorax and abdomen. 



8. Thoracic and lateral ab- 

 dominal bands much darker in 

 colour. 



9. Transverse bands of ab- 

 domen darker in colour and well 

 defined. 



The specimens which Mr. 

 Harrison 1 } obtained from the Blue- 

 bellied lorikeet, Trichoglossus no- 

 vœ-hollandiœ, closely resemble the present species as regards the size 

 of body, the shape of head, the chaetotaxy of metathorax, and the 

 colour of body markings. They were provisionally assigned by him 

 to P. australis, but are, in my opinion probably identical with the 

 present new species.
