beyond the cell. A broad black marginal band containing 
ill-defined pairs of whitish streaks ; the dots.on cilia clear 
white. Across the centre of wing is a black macular band 
terminating with a yellow spot enclosed by black. Some 
faint yellow scaling between the black spots composing the 
band. 
Hab. N. Peru, Rentema Falls, Upper Maranon, 1000 ft. ; 
Chinchipe River, 6000 ft., September 1912; Charape, 
4000 ft. (A. & E. Pratt). 
63d,1?2. 
Hleliconius numata silvaniformis, J. & K., subsp. n. 
Fore wing above with the basal half ochreous. A very 
heavy black nail-shaped blotch within the cell. Costa black. 
_A heavy black curved band along vein 1. A large, square, 
black discoidal blotch joined to the black costal stripe. 
Space between basal black blotch and discoidal black blotch 
yellow suffused with ochreous. Beyond discoidal blotch is 
a transverse yellow band much broken up on its outer edge. 
Two large black blotches between veins 2, 3 and 3, 4, and 
touching one another. A heavy black wedge-shaped blotch 
running up from outer margin touches the upper of the two 
black blotches at the lower angle. Apex black, with three 
yellow spots, the two upper ones almost contiguous. 
Hind wing above ochreous, with a rather narrow black 
transverse band. A black marginal band almost uniting 
with transverse band between veins 8,4 and thence com- 
pletely to apex, containing two or three pairs of small yellow 
spots. A series of marginal yellowish-white dashes. 
Hab. Lower Amazon, Para, Jan.—March, 1914 (A. Hall). 
This insect strongly recalls silvana diffusa, from which it 
may be separated by the heavy black pointed blotch in cell, 
silvana having instead a small round blotch only. Dr, El- 
tringham has treated silvana and numata as conspecific, but 
we cannot follow this for the present. 
Sic Heliconius ignotus, J. & K., sp. n. 
Fore wing above with the basal half brownish ochreous, 
A large black wedge-shaped basal streak joined (or sometimes 
separate) to a Jarge roundish black patch. Costa black and 
a large black discoidal patch united with the black thorax, 
A rather narrow discal yellow band ending quite pointedly 
just beyond vein 2 close to outer margin. In the middle of 
this band just beyond cell between veins 3, 4 is a rather 
small black spot, and below vein 3 is a larger black spot.
