390 Records of the Indian Musetim. [Vol. XXIl , 



Xylocopa fenestrata (Fab.), p. 539. 



Barkuda, 2 ex., 25-vii-4-viii-i7 (Annandale) ; ix-iq [ByiineUi). 

 A widely distributed species rare on the island. 



Xylocopa nr. fenestrata (Fab.) 



Barkuda, i ex , iv-20 [Annandale and Dover). 



This specimen seems to be intermediate between X. fenestrata 

 (Fab.) and X. lunata Klug, which Bingham doubtfully sunk as a 

 synonym of the former species. It differs from both forms m the 

 possession of a comparativelj' large and a small, almost reniform, 

 hyaline marking on the hindwings. Were it not for the. fact 

 that the large marking on the right hindwing is almost lost I 

 might have been tempted to describe this as a new variety of X. 

 fenestrata. 



Xylocopa aestuans (lyinn.), p. 540. 



Barkuda, 18 ex., 3-i9-viii-i9 {Gravely); i6-20-ix-i9 (Bru- 

 neiti); 25-vii-4-viii-i7 {Annandale); 26-iv-20 {Dover); 7-vi-20 

 {Annandale). 



The most abundant Xylocopa on the island at all seasons. 

 Its favourite food-plant appears to be the pea Crotolaria striata. 

 It often bores in a dead log, cutting a rather neat round hole 

 as an entrance to the nest. The handle of a disused falki (a sort 

 of native carriage) was completely ruined by these insects in this 

 manner. 



Xylocopa rufescens Smith, p. 543. 



Barkuda, 3 ex., 25-vii-4-viii-i7 {Annandale) ; i-6-ix-i9 (An- 

 nandale) ; 26-iv-20 {Dover). 



Previously recorded by Bingham from Sikkim, Burma, Te- 

 nasserim, Java, Sumatra, and Borneo. It is represented in the 

 collection of the Z.S.I, from the Andamans, Singapore, Sikkim, 

 Murshidabad and the Ganjam dist. A comparatively rare bee of 

 crepuscular habits. Its capture in the plains of Peninsular India 

 is interesting. 



The Indian Museum possesses three specimens from South 

 Malabar identified as Xylocopa ferruginea L,epel., a species relegated 

 to a foot-note description in Bingham's volume, as he had not been 

 able to identify it. I am inclined to think that these examples 

 are in reality X. rufescens, but they are in too bad a condition to 

 admit of a definite opinion being expressed. 



Tribe TUBUUFERA. 

 Family Chrysididae. 



Stilbum cyanorum var. splendidum (Fab.), II, p. 432. 



Barkuda, i ex., iv-20 (Annandale and Dover). 

 A cosmopolitan species.
