NOVITATES ZOOLOGICAE XXIII. 1916. 229 



stigma obsolete ; subterminal line paler, more sharply inbent below the angle at 



vein 7, making that angle and the one below 4 appear more prominent. 



Hindwing paler, with the lines less marked ; underside pale, without markings or 

 dusting, except a dark apical shade. 



Head, thorax, and abdomen pale greyish ochreous, the patagia darker, like 

 basal area of forewing. 



Described from a single ? from Nakheila, R. Atbara, Lower Egypt, taken by 

 Mr. N. C. Rothschild in February 1904, along with a long series of C. fasciolata, 

 among which it was overlooked. In breadth of median area and shape of lines it 

 agrees with G. dispar Piing. from Syria, but in coloration it is quite different. 



ON THE POEMS OF BHODINOCICBLA ROSEA. 



By ERNST HARTERT 



SEVERAL subspecies of Rhodinocichla rosea have recently been separated, but 

 the Venezuelan form has always been united with the one from Colombia. 

 This is not correct, as the former is considerably paler, more greyish on the upper- 

 side, and smaller, the rufous of the throat and breast of the female lighter. In fact 

 the Venezuelan form is in the coloration of the upperside like Rh. rosea schistacea, 

 from Western Mexico, but it is smaller and the throat and breast are considerably 

 paler. The wings of our Venezuelan specimens measure, in the male, 81-84, ? 

 77-84, those of Colombian (Bogota), males 89-93, ? 83, while males of Rh. rosea 

 schistacea have wings of 87-91, females 85-89 mm. 



Rhodinocichla rosea was first described as Furnarius roseus by Lesson, Illustr. 

 Zool. pi. 5 and text (1832-43 — "San Jose', Brazil"). Lafresnaye, in his critical 

 notes on types in the Paris Museum (Rev. Zool. viii. 1845, p. 10) showed that the 

 type did not come from Brazil, but from Colombia. In 1849 Hartlaub described 

 a female from Caracas, Venezuela, collected by M. A. Rojas, in the Hamburg 

 Museum, as " Turdus vulpinus" (Rev. Zool. 1849, p. 276). Not only does the 

 name clearly refer to a Venezuelan bird, but the description of the upper surface as 

 " olivaceo-cinerascentibns " absolutely fits the Venezuelan race, while the back of 

 the Colombian race would be described as " nigro-schistaceus." Therefore the 

 name vulpinus must be accepted for the Venezuelan Rose-breasted Mocking Thrush. 

 The species would, so far, be separable into the following subspecies : 



Rhodinocichla rosea rosea (Less.) : Colombia. 



Rh. rosea eximia Ridgw. : Panama to Costa Rica. 



Rh. rosea zulpina (Hartl.) : Venezuela (Caracas ; from Caripe, San Esteban, 

 Tucuyo, and Ejido, collected by Mocquerys, in the Tring Museum). 



Rh. rosea schistacea Ridgw.: Western Mexico. 



There is, of course, no reason why schistacea should be treated as a species and 

 uamed binomially, as Mr. Ridgway (B. North and Middle America, ii. p. 772) 

 has done. Rh. rosea vidpina is quite as different from Rh. rosea rosea as is 

 schistacea, and all the known forms agreeing in their main features, differing only 

 slightly in tint of coloration and size, and representing each other in their distribu- 

 tion, the only reasonable treatment is to name them trinomially, as above.
