Show 1900.] ON BUTTERFLIES FROM BRITISH EAST AFRICA. 911 The spermathecce 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 m m . ; 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. Hab. Malay Peninsula. 6.

Early in the present year I received a letter from Mr. Crawshay (Nairobi, March 17),in which he says : - " I am taking the opportunity, now that 1 a m 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 foliow7s :- " 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. |
