446 RHOPALOCERA MALAY AN A. 



Additional H.\b. — Malay Peninsula ; Penang (Biggs — coll. Dist.) ; Province Wellesley (Birch) ; Perak 

 (Kiinstl. — Calc. Mus.) ; Sungei Ujong (Durnford — coll. Dist.) ; Singapore (Kerr — coll. Dist.). — Borneo; 

 Sandakau (coll. Pryer). 



From information contained in a letter sent me by Mr. J. K. Birch, this species appears 

 to be not uncommon in some parts of Province Wellesley in the month of December. 



Genus HESTINA {to follow Hypolimnas). 



ILstiiM, Westwood, Diadeuia, sect. 6, Geu. Diuru. Lap. p. 281 (1850). 



This genus may be synoptically separated from Hypolimnas, with which it has considerable affinity, 

 by the character of the cells of both wings being open and not closed by a disco-cellular nervule. 



The distribution of this genus appears to be foeussed in Northern India, and it is also 

 found in China.

Male. Anterior wings above very dark indigo-blue, with the following pale bluish markings:— a basal 

 streak in cell, followed by two spots, and two other similar spots at end of cell, a curved discal series of six 

 linear spots placed between the uervules, the lowermost longest and duplex ; beyond these are an irregular 

 cluster of spots, with a distinct submarginal series, basal two-thirds of inner margin pale bluish. Posterior 

 wings creamy with a bluish tinge, the neuration and a broad outer margin castaneous, the last containing 

 some dark spots which are inwardly margined by some small pale creamy spots, extreme outer margin 

 sublunulate and paler in hue. Anterior wings beneath as above, but the ground colour of the apical area 

 ferruginous ; posterior wings beneath as above, but paler, and with the outer sublunulate spots creamy 

 white and with three somewhat large subapical spots of the same colour. Body above dark indigo-blue ; 

 head and anterior portion of pronotum spotted with creamy-white, lateral margins of pronotum pale 

 bluish-grey ; body beneath thickly spotted with creamy- white ; abdomen with a lateral stripe of the same 

 colour on each side ; legs streaked with creamy-white. 



Exp. wings, (? , 85 to 90 millim. 



Hab. — Continental India; Sikkim (de Nic). — Malay Peninsula; Perak (Egerton — coll. Dist.). 



The exertions of Mr. W. Egerton have enabled me to add this butterfly to the list of 

 species composing our rhopaloceroiis fauna. My collection contains male specimens only, and 

 Mr. de Niceville narrates his collecting experiences in Sikkim with reference to this species as 

 " males only taken on the lower hills. On the wing it much resembles Dannis Ujtia."* 



Genus CETHOSIA {antea, p. 170).

■'■ This of course does not necessarily imply that one species mimics the other, though such is probably the case. In 

 forming these hkely conclusions one is reminded of the apothegm of Bacon :— " The Lord St. Albans, who was not over hasty 

 to raise theories, but proceeded slowly by experiments, was wont to say to some philosophers, who would not go his pace, 

 ' Gentlemen, nature is a labyrinth, in which the very haste you move with will make you lose your way.' "
