Captain G. D. H. Carpenter's Pierines from Lulanguru 

 and St. Michael's Mission. — Dr. F. A. Dixey exhibited 

 Capt. Carpenter's Pierines and made the following observa- 

 tions : — 



The Pierines collected by Capt. G. D. H. Carpenter at 

 Lulanguru, seventeen miles W. of Tabora in East Africa, are 

 in several respects of great interest. The most noteworthy 

 captures are as follows : — 



(1) A series of Teracolus ducissa, Dognin, consisting of five 

 males and seven females, including one pair taken in cop. 

 This pair settles the question of the male of T. ducissa, which 

 has been erroneously stated to be like the female. In reality 

 it bears considerable resemblance to the male of T. sub- 

 fascial as. Swains., from which it is chiefly distinguishable by 



the fact of the dark subapical bar of the fore-wing being 

 continuous into the hind margin, and the included apical 

 ground-colour being of a deeper orange. Aurivillius in Seitz, 

 tk Macrolepidoptera of the Ethiopian Region," p. 61, describes 

 the male of T. ducissa as differing only from the female by 

 its yellow ground-colour. His figures of the sexes {ibid., 

 pi. 20, f, g) really represent two females ; but the same plate 

 contains a figure of w ' subfasciatus $," which may very well 

 have been drawn from the male of T. ducissa. My attention 

 was called to this by Prof. Poulton. 



(2) A long series of Teracolus casta, Gerst.. comprising 

 twelve males and seventeen females; twelve of the total 

 number were taken paired. The males are mostly of the large 

 dark-bordered form called sipylus by Swinhoe. The females 

 show a remarkable range of variation. 



The captures range in date from July 25, l!»17, to Jan. 2. 1918. 

 Capt. Carpenter notes that the wet season began from the end of 

 November. In most of the species there is a well-marked corre- 

 spondence with the change in meteorological conditions. This 

 is evident in the case of the three species of Terias, T. brigitta, 

 Cram., regularis, Putl.. and senegalensis, Boisd., though not 

 without some exceptions. The specimens of the first-named 

 species were caught July 25-Aug. 1 . and are all of t he dry-season 

 form, the males being somewhat transitional, and the females, 

 as is usual, having the dry-season character more strongly
