422 ME. B. B. SHARPE ON THE BIKDS OF NEW GUINEA. 



POSTSCEIPT. 



In the same package with the materials for the marine Caddis- 

 fly Prof. Hutton forwarded specimens illustrating the economy 

 of two other species of New-Zealand Trichoptera, from the Weka 

 Pass, Canterbiiry. 



(i.) Helicopsyche. — Numerous cases regularly formed, con- 

 structed of fine sand, 3J-4 millim. in diameter by l|-2^ millim. 

 high, with nearly three complete whorls. Some are empty; 

 others contain larvsB and pupse. Accompanying them were two 

 female pupte emerged from the cases, and ready for the final 

 metamorphosis. So far as can be judged, the perfect insect should 

 be congeneric with the species that have been reared in Europe 

 and in North and South America. I refrain from bestowing 

 names upon cases only *. 



(ii.) Fixed cases, probably constructed by the larvpe of some 

 unknown genus and species of Ehyacophilidse, which should be of 

 about the size of some of the smaller European species of Bhyaco- 

 pJiila. The pupa is enveloped in a special cocoon, as is usual in the 

 family, and does not agree with the genus Bhyacophila either in 

 spurs or palj)i. Philanisus having been removed from the family, 

 the latter is now without any described representative in New 

 Zealand. Of two cases, one is wholly composed of stony (? gra- 

 nitic) fragments ; the other partially of similar fragments, par- 

 tially of shells (of two or three species), and partially of the cases 

 of the Helicopsyche referred to above. 



Contributions to the Ornithology of New G-uinea. 



By E. BowDLER Sharpe, E.L.S.— Part VIII. 



[Read May 4, 1882.] 



The present paper contains notes on collections made by Mr. 

 A. Goldie in districts at the back of the Astrolabe range, in 

 South-eastern New G-uinea, and by Mr. Charles Hunstein on 

 Normanby Island, on the south shore of the mainland of the 

 China Straits, and on the banks of a river at the end of Milne 

 Bay. 



In a communication which I recently made to this Society 

 {antea, p. 317), I gave diagnoses of certain undescribed species 

 of birds which had been forwarded to my friends Messrs. Osbert 



* Helicopsyche-ca,Bes from New Zealand have long been in the British Museum, 

 and have several times been alluded to by me in various published notes.
