This species should perhaps be placed in another genus, as it differs 

 somewhat structurally from Philentoma pyrhoptera, but if so Drymo- 

 phila Temminck (March 1825) cannot be used on account of Drymo- 

 phila Such (January 1825). 



P. V. caesia ranges from Sumatra north through the Malay States 

 and Peninsular Siam to southern Tenasserim. 



PHILENTOMA PYRHOPTERA PYRHOPTERA (Temminck) 



Muscicapa pyrhoptera Temminck, Nouveaii recueil de planches colorizes d'oiseaux, 

 livr. 101, pi. 596, fig. 1, 1836 (Borneo and South Sumatra; type locality 

 restricted, Borneo). 



Two females, Sichol, Bandon, August 29-September 1, 1929; one 

 male, Tha Lo, Bandon, September 23, 1931; three females and one 

 unsexed, Kao Sai Dao, Trang, December 30, 31, 1933, and January 

 8, 1934. 



Dr. W. L. Abbott collected one male and three females. Lay Song 

 Hong, Trang, September 1-December 29, 1896; one male, Kao Soi 

 Dao, 1,000 feet, Trang, February 18, 1899; one male, Tandjong 

 Badak, Tenasserim January 7, 1900. He gives the soft parts of the 

 male as: Iris crimson; bill black; feet brownish leaden. The iris in 

 one female is given as dark brown, otherwise as in the male. Another 

 female has the bill black above, pale brownish fleshy below; iris dark 

 red. This latter is the usual condition. All the females collected by 

 Dr. Smith have light-colored bills. Only one female collected by Dr. 

 Abbott has a black bill. 



For comparison I have two males and one female from Borneo ; one 

 male is a deeper buff on the chest than any male in the Malay Penin- 

 sula series ; the other male shows no differences from the latter. The 

 female from Borneo is lighter above and a deeper buff below than any 

 female in the Peninsular series. 



The one male from Tenasserim and three from Peninsular Siam 

 measure: Wing, 81-87 (83.5) ; culmen, 16.5-17 (16.8) mm. Two males 

 from Borneo: Wing, 86-89.5; culmen, 16.5-17 mm. Two males from 

 Sumatra: Wing, 79-82; culmen, 16-17 mm. Five females from 

 Peninsular Siam: Wing, 75-82 (79.4); culmen, 15.5-16.5 (16) mm. 

 One female from Borneo: Wing, 79.5; culmen, 14.5 mm. 



The present form ranges from southern Tenasserim through Penin- 

 sular Siam to the Malay States, Sumatra, Borneo, and Cochincliina.
