and Mr. E. E. Green remarked on the difference between the 

 inner marginal border of their hind-wing pattern and that 

 of Ceylon specimens. The latter seemed to them to show a 

 smaller development of the red markings in this region. 

 Prof. Poulton had since carefully compared the specimens 

 and found that the difference in appearance was due to two 

 out of the three red markings in area Ic of the western females 

 being fused in the eastern females into a single long basally 

 placed streak, the outermost marking remaining separate 

 in both localities. The basal division into 2 separate mark- 

 ings was sometimes indicated by a notch which occasionally 

 (for example in 2 Singapore females taken in January, 1916) 

 broke through, producing a pattern like that found in the 

 great majority of the polytes females in Ceylon. Among 

 these latter too the same fusion into a single notched streak 

 occasionally took place. So far as could be inferred from the 

 insufficient material in the Hope Department specimens from 

 the mainland of India were intermediate in this respect 

 between those from Ceylon and Singapore. It would be 

 very interesting to breed from the exceptional females in both 

 east and west. 

 Predaceous Reduviid bugs and Fossors, with their 



PREY, FROM THE S. PaULO DISTRICT OF SoUTH-EaST BrAZIL. — 



Prof. Poulton exhibited and described a set of predaceous 

 insects captured 1913-16 by Dr. Gregorio Bondar in the S. Paulo 

 district of S.E. Brazil, and presented to the Hope Department 

 by Mr. G. A. J. Rothney. In determining the species kind 

 help had been received from Mr. C. J. Gahan, Mr. W. L. 

 Distant, Mr. K. G. Blair, Mr. R. South, Mr. A. S. Hirst, and 

 especially from Dr. G. A. K. Marshall and Mr. Rowland 

 E. Turner; in interpreting the often indistinctly written 

 Portuguese on some of the labels, kind help had been given 

 by Don Fernando de Arteaga. The great majority of the 

 observations had been made at Piracicaba, about 100 miles 

 N.W. of S. Paulo, in S.E. Brazil; others at Campinas, about 

 70 miles N.W. of the same city. 



The Reduviid captors and their prey — almost invariably 

 insects belonging to the specially protected groups — were 

 shown in the following table : —
