36 MR. BUTLER ON NEW SPECIES OF PROTOGONIUS. ([Jan. 19, 
running from second third of costa to near the end of second median 
interspace; four apical submarginal ochreous spots, the two upper 
ones largest, the first sagittate; secondaries with the costal half 
tawny, the costa, subcostal vein, and anal half black ; an apical sub- 
marginal blackish line; four submarginal tawny-tinted white spots : 
body brown; antennze with the apical three-fifths yellow, base black : 
wings below very like P. tithoreides; primaries paler, two or three 
pale stramineous subapical spots; secondaries darker, the costal half 
of wing suffused with castaneous. Expanse of wings 3 inches 4 lines. 
Pebas. Coll. Druce. 
Apparently a mimic of Tithorea megara. 
3. PRoroGonivus DIFFuUsus, n. sp. (Plate V. fig. 3.) 
Wings above tawny; primaries with the apex from costa just 
beyond end of cell to third median branch dark brown, outer margin 
from third to first median branch narrowly bordered with brown; a 
rather broad band from basal costa to end of cell, uniting with an 
irregular oblique band from end of cell, crossing second median in- 
terspace near the base ; a broad black internal streak, nearly reaching 
external angle; a broad subapical ochreous band, diffused and fading 
away into the” ground-colour below second median branch ; secon- 
daries with the costa narrowly black ; outer margin broadly bordered 
with black, tapering from inner margin to second subcostal branch ; 
three small pale ochreous submarginal spots: body olivaceous, 
clothed with tawny hairs; antennze with apical two thirds ochreous, 
base black ; wings below much as in P. @quatorialis, but secondaries 
with the bands dark brown on costal area, and anal area plumba- 
ginous. Expanse of wings 3 inches 6 lines. 
Curaray, Ecuador. Coll. Druce. 
This species probably mimics Melinga zaneka or Mechanitis fallax. 
4, PROTOGONIUS SEMIFULVUS, n. sp. (Plate V. fig. 4.) 
Primaries above bright tawny; a broad patch at apex, the costa, 
a streak covering costal area to end of cell and terminating in a large 
discocellular spot, and a broad internal streak black; secondaries 
black; a broad patch at apex bright tawny, the base of cell and 
costal area dull tawny; abdominal area brown: body brown; an- 
tennee pale yellow, basal joint black ; under surface almost as in P. 
tithoreides, but without subapical white spot. 
Villagomes, Ecuador. Coll. Druce. 
Mimics Melinea methone and parallels Meehanitis decepta, Cera- 
tinia semifulva, Heliconius bicoloratus, Eresia ithomiola, and Peri- 
copis hydra, all of which are coloured in the same way and range 
over the same region.
