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.

Heliconius namata silvaniformis , J. & K., subsp. n. 



Fore wing above with the basal half ochreous. A very 

 heavy black nai!-shaj)ed 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 unitino- 

 with transverse band between veins 3, 4 and thence com- 

 pletely to apex, containing two or three pairs of small yellow 

 spots. A series of marginal yellowish-white dashes. 



Bah. Lower Amazon, Para, Jan.-March, 1914 {A. Ball). 



This insect strongly recalls silvana difusa, 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 niimata as conspecific, but 

 we cannot follow this for the present. 



Heliconius ignotiis, 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 large roundish black patch. Costa black and 

 a large black discoidal patch united with the black thorax. 

 A rather narrow discal j^ellow 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.
