1900.] ON BUTTERFLIES FROM BRITISH EAST AFRICA. 911 



The spevmathecce are four pairs in segments vi.-ix. The main 

 pouch is circular, sometimes even kidney-shaped in outline ; in the 

 latter case the duct arises from the hilum. The duct is quite as 

 long as the pouch '. The diverticulum is altogether longer than 

 the spermathecae ; it is made up of an oval pouch and a long duct. 

 In the neighbourhood of the second or third spermatheca is a soft 

 cushion-like gland, bilobed, which appears to be related to the 

 papillae upon the spermathecal segments. 



The following definition of the species includes the principal 

 characters of 



Amyntas biporus, n. sp. 



Length 115 mm. ; number of segments 93. Anterior setae a 

 little stouter than upon succeeding segments. Clitellum xiv.-xvi., 

 with setae upon all segments. Genital papillae upon vii., viii., and 

 upon xix. a pair of slit-like orifices leading into a sac resembling a 

 bursa copulatrix and with penis-like process. Male pores far apart. 

 Gizzard-septum absent. Caeca present. Last hearts in xiii. 

 Sperm-sacs in x., xi., xii. Spermiducal glands in xvii.-xix., with 

 horseshoe-shaped duct and small terminal sac. Spermathecae in 

 vi.-ix., with long diverticulum. 



Hub. Malay Peninsula.

(Plate LVIII.) 



Early in the present year I received a letter from Mr. Crawshay 

 (Nairobi, March 17), in which he says : — " I am taking the oppor- 

 tunity, now that 1 am in actual close touch with a reliable post- 

 office, to send you another consignment of Lepidoptera, about 

 three hundred insects in all, some of which ought to prove 

 especially interesting, as latterly I have been collecting high up in 

 Kikuvu in primaeval forest, at altitudes varying from 7500 to 

 7800*feet." 



These insects (two boxes) came safely to hand, and about a 

 month later a second (smaller) consignment, together with a letter 

 dated April 1st, as follows : — 



"1 have to write you an introduction to the collection of 

 Lepidoptera despatched to you some three weeks ago. 



" As far as I can recollect, there are no insects — Butterflies, that 



1 This is not always apparent. Sometimes the diverticulum is shorter ; hence 

 the need for care in basing specific distinctions.
