some Oriental Nycteribiida?, 227 



line near tlie apex ; [some variation is noticeable, e. g. the 

 ? from Bihar has an extra tour bristles situated two on 

 either side of the median line midway between the basal and 

 median pairs, and this specimen also has the apex of the 

 sternite shallowiy emarginate, a character not observed in 

 any other] . Subi/enifal plate almost hidden under sternite 5, 

 undivided, with bluntly rouiuled ajjcx, and several longish 

 bristles on and near its margin on cither bivle. 



The form of the ? abdomen in 6'. roy/ei is quite unlike 

 that of any other Nyctcribiid known to me. The very 

 great length of the basal segment is higldy remarkable, as, 

 too, is the extraordinary arching forwards of the second, 

 third, and fourth sternites. The i)Osition of the spiracles also 

 appears curious ; two pairs are visible dorsally on the con- 

 ncxivum, one pair rather close to the middle line, immediately 

 adjacent to the inner side of the anterior extremities of the 

 lateral dark areas, and another not mnch posterior to this, 

 but situated quite at the sides of the body. Two other pairs 

 are visible on the connexivum ventrally, close behind the 

 outer angles of sternites 2 and 3. 



Loc. ^Malay Peninsula, Ceylon, India. 

 "Wcstwood^s type of Nycteribia roylei was recorded from 

 '' India orientalis '"' without further particulars, and the host 

 was unrecorded. The specimens described by Speiser as 

 Nycteribia chlamydophora were from the Malay Peninsula, 

 from Biserat, Jalor, and from Bukit Besar, in both cases on 

 Scotophilus castaneus, Horsfield, which Mr. Oldfield Thomas 

 considers to Ije merely a form of Scotophilus kuhli, Leach 

 (see below). 



3 (J and 1 $ were obtained by T. Bainbrigge Fletcher 

 on Scotophilus heathi, Horsfield, at Pusa, Bihar, India, 

 vi. 1911. Fryer's material from Ceylon is as follows: — 

 9 J and 18 ? on Scotophilus ivroi/ffhtoni, Thomas, Pera- 

 deniya, 1912 ; 3 c? on l^jlonycteris pachypus, Peradeniya, 

 9. xii. 1911 ; 1 c^ and 3 ? on the same host, Peradeniya, 

 20. xii. lull; 1 S ^"fl 2 ? probably from Scotophilus 

 loroughtoni, collected i. 1912 at Ambalangoda by Dr. Buguioa 

 and given by him to Fryer. 



Also the British Museum contains the following : — 

 2 dried ? ?, labelled "India: Hardwicke Bequest '■' (these 

 were referred to as " A^. roylii ? '^ by Walker, List. Dipt. iv. 

 p. IIJ-S) ; 1 dried ? taken in Madras on Megaderma lyra 

 (registration number 79. 51); ] ? in spirit taken at 

 Saidapet, Madras, 1. i. 1908, on Scotojihilus kuhli.
