collected in islands other than Luzon, and for this reason local- 

 ities are given for each species of the second century. Another 

 series of Diptera, chiefly blood-sucking forms, has been received 

 from Mr. M. B. Mitzmain, Alabang, Rizal Province, Luzon. This 

 locality is about 35 kilometers from Los Banos. 



101. Plecia fulvicollis Fabr. 1805. 



Los Banos. A very common species spread over all the 

 Oriental Region and extending also to- New Guinea and Austra- 

 lia. It is very variable in size, one female specimen measur- 

 ing only 4 millimeters in length, like an Indian one recorded by 

 Brunetti. 2 



102. Bibio rubicundus van der Wulp. 1884. 



Some females from Mount Banahao. Previously known only 

 from Java. A very characteristic species, differing from Bi- 

 bio obediens 0. S. (New Guinea) in the yellow coloration of the 

 wings; the antennal flagellum, wanting in van der Wulp's type, 

 is black; on the contrary, the scape, which is said to be black, 

 is yellow in the present specimens, as in obediens. The very 

 long spur of the front tibiae about as long as the tibia is dark 

 reddish. The wings have the stigma pale yellow and rather 

 broad; the second posterior cell is sessile at base. 



103. Culicoides judicandus sp. nov. 



Female. Length of body, 1 millimeter. Near C. molests 

 Skuse of Australia and C. guttifer de Meijere of Java, but the 

 wing pubescence very scanty and confined to the extreme tip 

 of the wings. In this character it agrees with C. pungens de 

 Meijere of Java; but the wing pattern is more like that of 

 guttifer, from which it differs chiefly in having a clear spot at 

 end of the subcostal cell, and in the fact that the clear marginal 

 spots are not in contact with the wing margin, but are placed at 

 a little distance from it; the other spots are distributed as in 

 guttifer. Neuration the same as in guttifer. Body brownish 

 black, without distinct pattern. Legs dark brown, with the 

 knees and the tips of tibiae and tarsi whitish yellow. Antennae 

 short and blackish. 



LUZON, Rizal, Alabang (Mitzmain). Mr. Mitzmain has used 

 this gnat in experiments on the transmission of surra. 



104. Pselliophora suspirans 0. S. 1882. 



Mount Maquiling. An endemic species. The present speci- 

 mens differ from Osten Sacken's description in having a rounded
