purpose, especially such as smells strong and rotten. The females 

 are rarely seen compared to the males ; they keep to the thicker 

 parts of the forests and do not bask or indulge in pleasure -flights, and 

 imbibe nourishment from the saps of trees and fruits. Neither males 

 nor females are ever seen at flowers. The insect is distributed in 

 India from Lower Bengal to South India, and occurs nowhere else, 

 though a very similar butterfly, C. psaphoit, inhabits Ceylon. The 

 larva has various food-plants ; Saccopetalum tomentosum, i/., a large 

 tree belonging to the Anonacece being one of the commonest : this is 

 related to the Custard-apple : another is Aglaia Ihtoralis, Talbot, a 

 relation of the Neem's and Tamarindus huika, L., the Tamarind, 

 though the last is not a favourite. 



35' Charaxes fabius, Fahr [V\. D, fig. 18). — Male and female uppersid6 

 black ; basal area of both wings brownish. Both wings crossed by a conspi- 

 cuous sinuous discal series of sulphur-yellow spots, separate on fore, continuous 

 on hindwing and a subterminal series of similar smaller spots, often incom- 

 plete towards apex of forewuig. Discal spots increase in size posteriorly, that in 

 interspace 1, being largest ; on hindwing they are subequal, but those in inter- 

 spaces 7 and 8 are paler, almost white. Forewing has also a sulphur-yellow spot, 

 at lower apex of cell and a costal one obliquely beyond, traversed by veins 8 and 

 9. Hindwing with a terminal incomplete line of spots posteriorly ending in a 

 larger blue spot at tornal angle. Underside lilacine-grey ; basal area with two 

 series of interrupted broken black lines ; discocellulars black ; discal spots and 

 those beyond apex of cell on forewing as on upperside, but white, diffuse out- 

 wardly and inwardly margined by short black lines. This is followed by an 

 irregular sinuous transverse row of ochraceous spots surrounded by black 

 shading, crossing both wings ; on the forewing the lower spots are margined, 

 beyond the black, with diffuse white and, on the hindwing, the posterior spots' 

 are margined mside by white lunules. The hindwing bears, in addition, an 

 inner subterminal series of white dots followed by an outer scries of ochrace- 

 ous spots lined inwardly black, then a few white spots and terminal black line. 

 The tails of hindwing are well developed, longer somewhat in the female, 

 slightly sharper in the male. Exp. •"52-92mm. 



Larva. — The body is subcylindrical, thickest at middle with the anal end 

 square, flattened, with a small conical, round-topped tubercle or point at each 

 posterior ; angle, about equal in breadth to the neck ; the head large, flat, more 

 or less hexagonal with slightly convex face furrowed shallowly and broadlj' 

 down centre, the surface rugose ; on margin there are small simple spines and 

 four horns lying in the same plane as the face, the two central horns pointing 

 straight up on vertex, separated at base by a distance equal to breadth of face 

 at eye-level and as long as breadth of head at middle ; the outside ones, rising 

 from a point ^ of the length of face from vertex of head, grow out, up and
