PRECIS TUGELA. Trimen. 



Precis tngela, Trimen, Trans. Ent. Soc. Loud., 1879, p. 334 (1887) ; S. AlV. Butt., I, 

 p. 241, pi. IV, fig. 5 (1887). 



The collection contains thirty-seven specimens of this si)ecies, only 

 four of which were submitted to me for examination. There are two 

 forms, one with the apex of the primaries very acute and falcate, as 

 represented in the tigure gixen by Mr. Trimen ; the other with the apex 

 likewise falcate, but the produced portion truncate at its extremity. I 

 am inclined to think that we are dealing here with a case of seasonal 

 dimorphism analogous to that which we observe in the case of Junonia 

 aJmana and Junonia asterie, which are the dry and wet seasonal forms 

 of the same insect. Aside from this difference in the outline and the 

 somewhat more distinct development of the markings in the form with 

 the acute apices of the primaries, I can see no difference sufficient to 

 warrant more than a varietal separation. Being at present engaged in 

 a revision of the African Nymphalid;e, I defer any further remarks upon 

 this subject until I shall have had opportunity to more thoroughly go 

 over the species of the genus Precis, of which I have enormous suites
