Fort Smith, June 25; Eoromo, 7800 feet, Dec. 17, 1899, Jan. 12, 1900. " I recognize this as the little insect I took at Ngong, where it is very plentiful. " Taken on the railway-line in tbe midst of thick forest on either side. I have not previously remarked a specimen of this insect at this altitude (7800 feet). " Here and there a solitary specimen seen ; not, as at Ngong, where sometimes six could be taken with a single stroke of the net." (R. C.) Mr. Crawshay evidently only sent us his best examples, or else we returned a series to his brother; we have five specimens from Ngong. 64. POLYOMMATUS B^TICUS. Papilio bceticus, Linnaeus, Syst. Nat. ed. 12, i. p. 789 (1767). cf cf, Eoromo, Dec. 17, 1899 ; Jan. 21, 1900. " An insect of irregular fluttering flight, fond of hovering low over moist ground, but, if once missed, very^difficult to take." (R. C.) 65. ZIZERA GAIKA. Lyccena gaika, Trimen, Trans. Ent. Soc (3) i. p. 403 (1862). cf, Nairobi, 5400 feet, March 17, 1900. " Taken on the open plain, half a mile from Nairobi railway-station." (R.C) For many years we have had an example of this species in the Museum labelled as received from Pernambuco ; I doubted the correctness of this locality, but M. de Johannis has shown me a second example which he said he knew to have been undoubtedly received from Brazil. 66. CHILADES TROCHILUS. Lyccena trochilus, Freyer, Neuere Beitr. Schm. v. p. 98,^pl. 440. fig. 1 (1844). Nairobi plains, 5400 feet, April 24, 1900. PAPILIONIDJE. 67. MYLOTHRIS RUBRICOSTA. Pieris rubricosta, Mabille, Ann. Soc. Ent. France, (6) x. p. 28 (1890); Nov. Lep. viii. p. 61, pi. 10. tig. 3 (1892). 2 , Nairobi plains, 5400 feet, March 28, 1900. Mr. Crawshay took this for a small example of the common 31. agathina; it is quite new to our collection, though a smaller example agreeing more nearly with M. Mabille's figure stands in the Hewitson collection. |
