Male. Anterior wings above greyisb-white, tbc base and basal balf of costal area bluisb-grey ; about 

 the apical half of wing black with its inner margin oblique and profoundly sinuate, and the apical third of 

 inner margin of the same colour. Posterior wings bluish-grey, the costal area blackish, a pale discal streak 

 extending "through and beyond cell, and the fringe pale greyish. Wings beneath pale brownish. Anterior 

 wings wiUi an obli.jue central whitish fascia, before and beyond which the colour is dark bluish-grey, and with 

 the following spots and fasci:e margined with grey :— two spots in cell, a disco-cellular elongate spot at apex 

 of cell, a spot between the tirst and second subcostal nervules and another between the second and third, 

 a waved fascia extending from fourth subcostal nervule to about upper median nervule, and a submarginal 

 row of small dark spots placed between the nervules. Posterior wings with the following spots and 

 fasciffi :— three beneath costal nervure, three crossing cell (the third at apex), two beneath cell (the second 

 bifid), beyond these a waved transverse fascia crossing wing, and a waved submarginal dark line. Body and 

 legs more or less concolorous with wings. 



Female, liesembling the male, but with the posterior wings more elongated and angulated ; the white 

 area of the anterior wings much larger, * and the white discal streak on the posterior wings also larger and 

 more distinct. 



Exp. wings, <? and ? , 34 to 42 millim. 



Hab.— Malay Peninsula ; Malacca (Pinwill— Brit. Mus. ; Biggs— coll. Gosse and Dist.)— Java (coll. 

 Horsf.); Batavia (Snellen). 



Although the male specimens collected in Malacca, and now before me, show no variation, 

 such miiformity in the species does not ensue when a larger series from the whole area of its 

 distribution is examined. As I have noticed in the British Museum and other private 

 collections, the variability is in the extent and distinctness of the white area to the anterior 

 wings. 



It is of this species that the erroneous statement as to its habitation in ants' nests has 

 been ascribed (antea, p. 205). 



2. Gerydus biggsii,f n. sp. (Tab. XXII. , lig. 12 2 .) 



Female. Anterior wings brown, almost crossed near centre by an oblique white fascia, beyond which 

 the brown colour is much darker and almost black. Posterior wings uniform brown, with the fringe paler. 

 Wings beneath pale brownish ; anterior wings with the white fascia as above ; both wings with spots and 

 fasciae margined with grey, arranged similarly to those of G. symctlius. 



Male. Resembling the female, but with the white fascia to the anterior wings a little narrower, and 

 the posterior wings more convex and less outwardly angulated. 



Exp. wings, 30 millim. 



Hab. — Malay Peninsida; Malacca (Biggs — coll. Dist.). 



I have now received three specimens of this well-marked species, all collected at 

 different times by Mr. Biggs at Malacca. I neither met with it myself in Province Wellesley, 

 nor have I seen it in any of the many collections examined from other parts of the Peninsula. 



* In an allied Amboinese species, G. hoisduvalii, Bull., the distinctive colouring of the sexes is reversed, the male having 

 the largest white area to the anterior wings. 



... .t.-'- '"^^^ named this species after its discoverer, the Kev. L. C. Biggs, now Chaplain at Malacca, who has devoted much 

 of his leisure to the collection aud study of tlie Bhopalocera of his tlistrict.
