(J. Upperside very close indeed to L. leptines, IIew. Underside 
not unlike L. juba, Fab., but the secondaries apparently have all the 
basal marks confluent, with a band of white beyond, following which 
is the postmedian line. I have been quite unable to discover where 
this type is or whether it exists. I therefore only know the insect 
from the figure in Donovan’s work {1. c.), and I havevei’y little doubt 
that the artist used both his imagination and his colour so as to 
improve upon his model. This is specially evident in the underside.

Neurypexina, gen, nov. 
The general neuration is similar to that of Lycaencsthes, 
but in the primaries 11 and 12 anastomose; veins 7 and 
8 are on a very long stalk branching to the apex and costa, 
very near the latter, so that 8 is quite a short vein ; the 
fork, however, is distinct under quite a low-power lens. 
Eyes hairy. Palpi thickly scaled with hairs, end segment 
long, smooth.

KEY TO SPECIES. 
1. Blackish, above with blacker spots and less 
dark intersjjaces. Below dark pattern 
closely compressed. lyzanius. 
2. Brown above, more uniform. Below white,

fewer markings than in lyzanius .... lamprocles.
