13. Taructis theophrastus. 



Hesperia theophrastus, Fabricius, Ent. Syst. iii. 1, p. 281, n. 32 

 (1793). 



LyccBna theophrastus, Lucas, Expl. Alg., Zool. iii. pi. 1. fig. 6 

 1849). 



c? 2, Lahej, 3rd April, 1883. 



Occurs also at Huswah according to Major Yerbury. 



M. Lucas's figure is not very characteristic. The species may 

 readily be distinguished from T. nara of India by the break iu the 

 submarginal series of spots on the under surface of the secondaries, 

 the spots towards the costa forming a line with those beyond the cell. 



14. ZlZERA TROCHILUS. 



LyccBna trochilus, Freyer, Neuere Beitr. v. pi. 440. fig. 1 (1844). 



Lyccena parva, Murray, Trans. Ent. Soc. 1874, p. 526, pi. 10. 

 fig. 1. 



Aden, 14th January; 3rd, 6 th, and 18th February; 6th, 12th, 

 and 19th March ; Huswah, 2nd March ; Lahej, 3rd April, 1884. 



The characters upon which Mr. Murray relied for the separation 

 of his L. parva from Zizera trochilus are not only slight but not 

 constant : — " Its much smaller size, and also from its presenting in 

 both wings a series of white markings immediately beyond the 

 discal row of spots." In the eleven Aden specimens before me the 

 size varies from 17 to 24 millimetres in expanse, the smallest 

 specimen therefore agreeing with Mr. Murray's type, and the largest 

 exceeding by 4 niillim. the largest of our other examples of Z. 

 trochilus ; the white markings also (which are only expansions 

 of the white borders to the ordinary spots) fail, or, more strictly 

 speaking, correspond with those of Z. trochilus, in two specimens 

 from the Transvaal in the Museum collection. 



15. Zizera knysna. 



Lyctena kni/sna, Trimen, Trans. Ent. Soc. ser. 3, vol. i. p. 282 

 (1862). 



Shaik Othman, 18th January, 9th March ; Huswah, 2nd April ; 

 Lahej, 3rd April, 1884. 



As a rule slightly larger than specimens from South Africa, but 

 exactly corresponding in every other respect ; one example taken at 

 Shaik Othman on the 20th April is somewhat aberrant, being small 

 even for typical Z. knysna, and with the under surface as white in 

 tint as that of Z. pygmtBa. 



16. Zizera gaika. 



Lyccena gaika, Trimen, Trans. Ent. Soc. ser. 3, vol. i. p. 403 

 (1862). 



Aden, 4 th February, 6th and 12th March ; Haithalkim, 4th 

 April, 1884. 



The specimens correspond in all respects with those from South 

 Africa.
