Hypocrita meander (part.), Snellen, Nat. Hist. Sumatr. p. 35 (mec 
Tijd. v. Ent, xxii. pl. vii. fig. 1] 
General aspect of J. meander from the Celebes, but cer- 
tainly distinct: primaries ochreous, with pale grey-brown 
markings, as follows—two convergent basicostal dashes, a 
slightly simuous oblique stripe, marched at costa, across the 
basal fourth, a zigzag stripe (the first angle of which unites 
with the first stripe) just before the middle, a sigmoidal stripe, 
and aseries of longitudinal discal dashes, the fitth and seventh 
of which are longer than the others; there are also two 
blackish dots at base of costa; fringe greyish: secondaries 
pale stramineous: body above ochreous, the head and thorax 
spotted with grey. Wangs below creamy stramineous, without 
markings, the primaries of a deeper colour than the secon- 
daries: body ochreous. Expanse of wings 41 millimetres. 
A specimen of this species was taken on the 7th of August, 
1879, on hilly ground at Bankala. 
Nyctemeride. 
3. Secusio picatus, sp. n. 
Allied to S. mundipictus, but larger, the interno-median 
streak of primaries wider, the white band longer and more 
oblique, its inner edge notched at origin of first median 
branch; the external border of secondaries considerably nar- 
rower, and on the upper surface terminating abruptly at the first 
median branch, but reappearing as a narrow greyish marginal 
dash near to anal angle ; abdomen grey, with white edges to 
the segments, black lateral (but not dorsal) spots, and ochreous 
anus; in other respects similar to the well-known species with 
which I have compared it. Expanse of wings 4 inches 4 lines. 
One female example. 
A. Trypheromera zerenoides, sp. n. 
Wings above snow-white, semitransparent; primaries with 
the costal border grey, crossed by an oblique white line near 
apex ; two unequal, almost confluent longitudinal grey streaks 
on the basal half of the cell ; three transverse series of more or 
less fusiform unequal grey spots, the first series just before the 
middle and uniting at its inferior extremity with the second 
series (which is interrupted on the first median interspace) ; 
second series discal; third series abbreviated, marginal, de- 
creasing, the second spot being, however, as small as the fifth 
and sixth ; secondaries immaculate: body ochreous, spotted 
with black, the spots of the dorsal abdominal series being
