NEW AND LITTLE'KNOWN BUTTERFLIES. 159 



larger quadrate spot near the middle of the first median interspace. 

 Ilindwing with a large oval anal snow-white patch, anteriorly crossed 

 by two veins of the ground-colour. Underside, foreiolng marked as 

 on the upperside. Hmdioing with the anal white area considerably 

 larger than on the upperside, and extending a little way along the 

 abdominal marghi. Cilia of the forewing fuscous ; of the hindwing 

 anteriorly fuscous, posteriorly snow-white. Anteiince, pa^n, head, 

 thorax, and abdomen at the base fuscous ; posterior two-thirds of the 

 abdomen snow-white, tipped with fuscous. 



At present there are two species only in the genus Iton* — " Hesperia" 

 semamora, Moore {=Hesperia barea, Hewitson), which has in 

 the male a tuft of hair turned forwards on the underside of the fore- 

 wing on the sutural area towards the base of the wing, and " Parnara " 

 watsonii, de Nioeville, which lacks this male secondary sexual 

 character. 7. azona agrees with the latter in this respect, but differs 

 from both species in having the antenn?e very perceptibly longer ; 

 the whip-like tip to the crook also longer. In markings it is nearest 

 to I. semamora ; on the underside, however, the ground-colour is wholly 

 black ; in /. semamora the costa and apex of the forewing and the 

 hindwing have the ground-colour ochreous ; on the hindwing also 

 the white area is very much smaller in I. azona. Mr. Hewitson's 

 description of the species is very short, being of four lines only ; he 

 gives its expanse as 2 inches, the habitat Macassar. Mr. Francis A. 

 Heron, of the British Museum, has kindly compared the drawing 

 here reproduced with the type, and says that it well agrees therewith. 



Described from a single example sent to me by the collector, Rerr 

 H. Fruhstorfer, from Patoenoeang or Patanuang in South Celebes. 

 Genus Stimula, n. n. 



I propose this name for the genus Watsonkt, Elwes and Edwards, 

 Trans. Zool. Soo. Lond., vol. xiv, p. 220 (1897), which is preoccupied 

 by the Marquis L. de Folin in the Molliisca (1879) ; type " Watsonia " 

 swinhoei, Elwes and Edwards. I have received a single male of 

 this species from the Khasi Hills from Mr. E. Svvinhoe, and two 

 males from Hsipaw, North Shan States, captured by Major F. B. 

 Longe, K.E. Superficially it hardly ditfers from Iverana diodes, 

 Moore, but has the wings narrower, the antennn? shorter, the lower
