 behalf of Mr. J. J. Joicey specimens of Papilio (Troides) 

 priamus r. coelestis, Roths., from Rossel Island and St. Aignan, 

 and the allied race urvilleana, Guer., from New Ireland and 

 the Solomons. The specimen shown of coelestis from St. 

 Aignan was very close to urvilleana. A ^ coelestis from 

 Rossel exhibited on the hind- wing the costal and discal yellow 

 spots of the type-form, which reappear as an aberration in 

 most priamus forms.

 masses of eggs of Stegomyia fasciata, the " yellow-fever 

 mosquito."

 hibited a live specimen of Xestdbium tessellatum, and demon- 

 strated its marked power of " ticking " in response to tapping 

 on the table on which the box stood in which it was contained.

 the question as to whether Anobium domesticum possessed the 

 same power.
