108 Mr. Butler's Brscrijyfions of 



black subcostal streaks, the inferior one l)roader and en- 

 closing a pale tawny spot ; two white apical spots ; twelve 

 marginal wdiite spots or strioles : expanse of wings, 3 inches, 

 6 lines. 



Venezuela (Dyson). 3 specimens. B.M. 



Mimics Mdincca Lilis, and differs from it just as Hcli- 

 conius Tdchinia does from M. Imitata. 



34. Hcliconius Diffusus, n. sj). 



Primaries above as in H. Sylvanm ; the discoidal black 

 spot obsolescent ; secondaries nearly as in ff. Nunudufi, l)ut 

 the discal black band narrower and the costal area entirely 

 greyish white ; the last two spots of the discal tawny band 

 slightly tinted externally with yellow scales : wings below 

 nearly as in H. Si/Ivanns, but primaries without the sub- 

 basal discoidal black spot; secondaries with the black spots 

 of the discal series considerably larger, and beyond them a 

 complete series of almost semicircular tawny spots, the two 

 last (at apex) slightly tinted externally with white : expanse 

 of wings, 3 inches, 3 lines. 



V^yI (Wallace). B.M. 



Mimics Melinwa Taraiya of Eeakirt ; the nearly allied 

 H. Sylvanus mimics IfcUnaxc Egena, and the differences 

 between the tw^o Mclina'a' and Hdiconii is about equal. 



44. Heliconius Miimdimts, n. sp. 



Closely allied to H. Wallacci, but with tlie steel blue 

 basal area more restricted ; the yellow spot in cell of pri- 

 maries enlarged, subquadrate, connecting the large inter- 

 median patch with the costa, thus forming a band as in H. 

 Sara ; the costal, subcostal, and median nervures dusted 

 with yellow scales from transverse band to base ; subapical 

 streak narrower : wings below olive brown ; yellow 

 markings as above ; primaries with base of costa red ; 

 secondaries with eight differently shaped red spots at base, 

 as in H. Wallacci ; apical area irrorated with whitish 

 scales ; basal lobe spotted with yellow : ex^janse of wings, 

 3 inches, 1 line. 



Bogota (Stevens). B.M. 



In the general character of the pattern of the upper 

 surface this species resembles H. Sara of Fabricius.
