314 Drs. Dixey and Longstaff’s Observations 
to dismiss forthwith the Kaffir driver, who doubtless, 
while he pocketed his easily-earned fare, pondered on the 
strange results of Huropean civilization and the increase of 
lunacy consequent thereon. 
The park is formed out of a piece of the primeval scrub 
of varied growth, filling a horseshoe-shaped hollow between 
the town and a tributary of the Buffalo. It is intersected 
with roads, footpaths, and streams; in parts are artificial 
shrubberies and flower-beds, which are gradually ousting 
the natural scrub. In the varied scene of insect life the 
most obvious characters were clouds of Mylothris agathina, 
Cram., of both sexes, their brilliant white and orange 
colouring showing clearly as they fluttered slowly and 
fearlessly over the large bushes of Poinsettia [Huphorbia 
pulchervima] glowing with their scarlet bracts. The males 
give out a strong scent very closely resembling that of 
sweet-briar. Amongst the agathina we took three speci- 
mens of the nearly allied riippellii, Koch, of both sexes, 
and in another part of the Park a single male of the 
delicate trimenia, Butl., with its pale yellow hind-wings. 
Less showy, but almost equally common, was Lelenois 
severina, Cram., the “common white” of this part of the 
world. Both sexes were well represented, the male having a 
distinct scent. All were of the dry-season form ; some were 
very small. Of B. gidica, Godt., a single male was taken, 
also strongly scented.* Of the more gaudily coloured 
B. zochalia, Boisd., two males and a female turned up. 
Terias was represented by a single brigitta, Cram., a 
male; Colias by two electra, Linn. also males; and 
Teracolus by two omphale, Godt., one of each sex. Last, 
but not least beautiful of the Piermes was Hronia cleodora,t 
Hiibn., of which five specimens were taken, while a male 
E. leda, Dbl., was netted, but it managed to get away. 
The widely-ranging Limnas chrysippus, Linn., of the 
typical African colouring, which, as is well known, is darker 
than in the Indian form, was flying slowly about in some 
numbers ; two females that were taken yielded the “ musk- 
rat” odour.

+ It is well known that the local races of H. cleodora show great 
differences in the amount of black bordering to the wings. This in 
the East London specimens is reduced toa minimum, See Drxey, 
Proc. Ent. Soc. Lond., 1905, p. lxvi.
