50 MR. A. Thomson's REPORT ON THE INSECT-HOUSE. [Feb. 1, 



9. Myiobius subochraceus, sp. iiov. 



Supra sordide olivaceo-viridis, uropygio paulo magis ochraceo ; alls 

 nigrlcaatibus, tectricum alariiim apicibus latis et secundariorum 

 mai'ginibus extends pallide fulvis ; cauda obscure cinerea : subtus 

 late ochraceus, in rostro medio magis flavescens ; subalaribus 

 pallide ochraceis ; rostro obscure fusco ; pedibus niyris : long,

Obs. Affinis M. pulchro, sed crassitie majore et colore subtus 

 ochraceo diversus. 



The specimen described is apparently a female of a third species 

 of the group of M. pulcher, distinguished by its large size and the 

 uniform ochraceous colouring below. There is just a faint appear- 

 ance of a bright colour on the crown, so that the male would 

 probably have a concealed orange crest. The bill is rather narrower 

 and more elongated than in M. bellus and M. pulcher.

 tibus ; alts schistaceo-nigris , tectricum alarium apicibus et secun-

]\Ir. Ridgway marlcs this bird, which has been submitted to his 

 examination, as " probably a new species, most like E. trailli in 

 coloration, but uith the outer web of the exterior rectrix white, as 

 in E. obscurus." I ])ropose to adopt this suggestion, which I quite 

 agree with, and to call the species Empidonax ridgwayi, after one 

 who has done so much good work in this group of birds. 



The second, third, and fourth primaries are nearly equal and 

 longest in this species. The first is shorter than the filth, and very 

 slightly longer than the sixth.

Dr. St. George Mivart, F.R.S., Vice-President, in the Chair. 



Mr. F. Day, F.Z.S., exhibited a specimen of a hybrid Pilchard, and 

 a specimen oi Salmo jiurjniratus raised in this country. 



A series of specimens of Lepidopterous Insects, which had been 

 bred in the Insect-house during the past season, was laid on the
