63. SCOLITANTIDES STELLATA. 



Lycmxa stellata, Trimen, Trans. Ent. Soc. London, 1883, p. 349. 



Fort Smith, June 25; Koromo, 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 the 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," (2?. O.) 



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 BJSTICUS. 



Papilio bceticvs, Linnaeus, Syst. Nat. ed. 12, i. p. 789 (1767). 



<J d , 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." 

 (S. C.) 



65. ZlZERA GAIKA. 



Lyccena cjaxka, Trimen, Trans. But. Soc. (3) i. p. 403 (1862). 



6 , Nairobi, 5400 feet, March 17, 1900. 



" Taken on the open plain, half a mile from Nairobi railway- 

 station." (B.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, Ereyer, Neuere Beitr. Schm. v. p. 98," pi. 440. 

 fig. 1 (1844). 



Nairobi plains, 5400 feet, April 24, 1900. 



PAPlLIONnXE. 



67. Mtlothris rubricosta. 



Pieris rubricosta, Mabille, Ann. Soc. Ent. France, (6) x. p. 28 

 (1890); Nov. Lep. viii. p. 61, pi. 10. fig. 3 (1892). 



? , Nairobi plains, 5400 feet, March 28, 1900. 



Mr. Crawshay took this for a small example of the common 

 M. acjathina ; it is quite new to our collection, though a smaller 

 example agreeing more nearly with M. Mabille's figure stands in 

 the Hewitson collection.
