Nuptial Flight of Pierines. It may be remembered that 

 in Proc. Ent. Soc. LoncL, 1917 : pp. 1 i i i , liv, a number of cases 

 were recorded in which paired specimens were taken by (apt. 

 Carpenter, the male in every instance but one supporting the 

 female. Since then many more pairs have been sent home 

 by Capt. Carpenter from the same locality (Itigi) as before ; 

 and in addition to these, further examples from Lulanguru. 

 The following is a list of all the Pierines actually captured in 

 the paired condition by Capt. Carpenter, including those 

 mentioned in the communication above referred to. It will 

 be understood that in every case the paired specimens them- 

 selves have been sent home by Capt. Carpenter, and may be 

 seen in the Hope Department. 



Teracolus casta, Gerst 17 pairs 



T. evagore, Klug 1 pair 



T. ducissa, Dogn 1 pair 



T. ackine, Cram 3 pairs 



Herpaenia eriphia, Godt I pair 



Pinacopteryx simana, Eopff. . . . -35 pairs 



Belenois gidica, Godt 1 pair 



B, mescal in«. Cram 10 pairs 



B. screri no, Cram 8 pairs 



Terias regularis, But! 1 pair 



T. senegalensis, Boisd 1 pair 



Catcpsilia florella, Fabr '2 pairs 



Eighty-one pairs in all. 



Inasmuch as (except in one pair of P. simana) the female 

 was invariably supported by the male, it may, I think, be 

 concluded that this is the general rule in the subfamily 

 Pierinae.
