Phylogeny of the Pierinee. 307 
A comparison of Tatochila (especially of J. theodice) 
with Phulia nymphula will show an almost exact identity 
of pattern, the correspondence extending even to the 
chevron-shaped spots of S in the hindwing, and to the 
peculiar triple striation of the nervules on the under 
surface. The neuration of Phulia is distinct, but not 
really far removed from that of Tatochila, some species 
of which show a near approach to its most remarkable 
feature ; viz., the emission of the second radial from the 
subcostal, and the consequent obliteration of the upper 
disco-cellular, Phulia again is closely allied in structure 
with Mr. Moore’s genus Baltia,* which, however, retains 
the short 38rd subcostal nervule lost by Phulia and 
several species of Synchloe. Phulia and Baltia are thus, 
in all probability, the terminal twigs of another branch 
which issued from the Pontia stem between the departure 
of Tatochila and Synchloe. Neophasia menapia appears 
to me to be an offshoot of the same stem at an earlier 
stage than Tutochila. It may possibly belong to the 
Bucheira group, but it is not known to make a social 
web,+ and Behr gives no real grounds for making it 
congeneric with “ N.” terlootii. As above noted, its 
neuration is very distinct from that of Huchetra. 
The African species of the genus Mylothris{ appear 
to hold a somewhat isolated position. Their neuration 
shows points of likeness with the equally isolated 
Australian genus Hlodine and the widely-spread and 
probably ancient Nychitona, || which genera they also 
somewhat resemble in texture of wing. In pattern 
they are chiefly remarkable for the strong and distinct 
development of series M, and of the precostal orange-red 
* Moore’s type is “ Mesapia” shawii of Bates, which is certainly 
generically distinct from J/. peloria, and much nearer Synchloe. 
The butterfly described by Moore in Proce. Zool. Soc., 1882, p. 234, 
as Synchloe butleri is undoubtedly a Baltia. 
+ Stretch, however (Papilio, ii, pp. 106, 107), describes the 
larve of N. menapia as suspending themselves from great heights 
at the end of long silken threads. Even the pup were, in some 
cases, suspended. It is probable that the numerous threads cover- 
ing the bark of the trees seen by Stretch (/bid.), were also made 
by these larvee. 
+ I cannot but agree with Mr. Trimen (South African Butter- 
flies, 1887, vol. iii, p. 29) that the American P. pyrrha, Fabr., 
and allies, are not generically akin to the African J/. agathina, M. 
chloris, etc., with which Mr. Butler unites them on account of 
their correspondence in neuration (Proc. Zool. Soc., 1892, pp. 37, 38).
