where the msect is sitting. Forms approaching the _ typical 

 occur here, but the palest is greyer than the type, and individuals 

 of the darker forms'^are more numerous than representatives of 

 the pale one. 



It would appear therefore that this aberration from light to 

 dark is a change brought about for protection, the conspicuous 

 pale form having gradually developed into the very inconspicuous 

 dark one. 



Mr. Barrett, in his great work, figured a specimen that I sent 

 him for that purpose, with a very similar but darker form of the 

 same aberration from Mr. Webb's collection; but the locality 

 from which this latter specimen came is not given. After 

 numerous inquiries I cannot discover that anyone has ever seen 

 or heard of this peculiar form occurring in any other locality, 

 though my inquiries extended even into Germany. 



Such a distinct and remarkable variety seems to deserve 

 a distinctive name, so I propose naming it Z. lyendularia var. 

 subroseata.

ON THE BUTTERFLIES COLLECTED IN EQUATORIAL 

 AFRICA BY CAPTAIN CLEMENT SYKES. 



By Emily Mary Sharpe. 



[My journey into the interior of Africa I commenced early in 

 1898. Starting from Mombasa in the train, which in those days 

 only took one 120 miles, I soon got to Kebwezi and Nairobi. 

 Both these places were excellent haunts for the entomologist, 

 and I much regret that I did not embark on making a collection 

 of Lepidoptera and Coleoptera until the time came for my return. 

 Alas ! I found myself steaming through these places in 1900 in 

 a train, and my opportunity had gone. 



I commenced my collection about July, 1899, when I was at 

 a place called Lamogi, in the valley of the Upper Nile, close to 

 Baker's old fort of Fatiko. Though there are woods in those 

 regions, there is little or no forest, and butterflies were rather 

 scarce. The Nymphalidse were principally represented. In 

 December, 1899, I journeyed to Wadelai, which is a far drier 

 and sandier place, and there the Pieridfe were fairly prolific. 

 More especially did Teracoli abound in great numbers and 

 varieties. Near the sandy banks of the Nile I could always 

 catch as many as I wanted. But the Nile District is a dis- 

 appointing country for the entomologist, who would naturally 

 expect many new species in such little frequented regions. In
