63. SCOLITANTIDES STELLATA. 



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



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 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 he taken with a single stroke of the 

 net." (E. 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). 



6 o% Roromo, 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." 

 (E. C.) 



65. ZlZERA GAIKA. 



Lyccena gailca, Trimen, Trans. Ent. Soc. (3) i. p. 403 (1862). 



c? , Nairobi, 5400 feet, March 17, 1900. 



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

 station." (E. O.) 



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, pi. 440. 

 fig. 1 (1844). 



Nairobi plains, 5400 feet, April 24, 1900. 



Papilionid^. 



67. Mylothris rubricosta. 



Pi ens 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. 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.
