to its hind margin, but apparently not near the lateral margins. 

 — The length and narrowness of the $ anal segment are charac- 

 teristic, and when this segment is viewed from the side it is often 

 seen to be curved ventrally. The curvature of the claspers (Speiser, 

 1. c, fig. b; Scott, op. cit., fig. 10) and the dark pigmentation of their 

 apices are also characteristic and constant. In the ? the constancy 

 of one characteristic feature throughout the series is noticeable: 

 on the dorsal chitinous plate before the anal segment (Scott, op. cit., 

 fig. 11c), the 4 (or 6) long bristles do not alternate with the short 

 thorn-like bristles on the hind-margin, but stand in a curved 

 row on the surface of the segment some way in front of the hind- 

 margin. This is an unusual arrangement, for in a number of species 

 when short thorn-like bristles and long bristles are present, the two 

 kinds alternate along the hind-margin, several short ones standing 

 between each two long ones (cf. parvula $, op. cit., fig. 17; &c). 

 The appearance of the two portions of the $ anal segment on 

 either side of the anus varies greatly according to the degree of 

 distension of the abdomen: in gravid they are divergent in 

 position, not parallel as in my fig. 11 (op. cit.). 



There are before me a number of specimens of this species 

 from Ceylon, which are decidedly smaller than the Sumatran and 

 Formosan specimens, but which otherwise agree with them closely. 



Loc. Sumatra, Ceylon, China, Formosa. 



Sumatra: Caves of Lian si Paghe, 1 1 $ (Museo Civico, 

 Genoa); host unrecorded. 



Ceylon: Peradeniya, X. 1911 and I. 1912, from Miniopterus 

 schreibersi (J. C. F. Fryer). 



China: Amoy, 1 $ 1 $ from Miniopterus schreibersi var. 

 blepotis, preserved dry in British Museum. 



Formosa: The great abundance of specimens found on Mi- 

 niopterus schreibersi in this island is attested by the following 

 list of material: 



In spirit: Tainan, 3. X. 1906, 80 & 79 ?. Tainan, 6. X. 1906, 

 34 c?, 52 $. Tainan, 7. X. 1906, 41c?, 32 ?. Taihorin, VI. 1911, 

 from an undetermined bat, 3 <$, 4 ?.

This species was described by Speiser from 2 ? from Sumatra, 

 preserved dry in the Museo Civico of Genoa. As only the one sex 

 was described, without figures, and from dried examples, I un- 

 fortunately did not recognise the specimens received from Formosa 

 in 1908 as this species, but described and figured both sexes as
