Idiijicr lluui tlie rcsjKHrtivc first tarsal sefi-nieuts, wliicli are about as long as the 

 cell dl' tin' liiiulwiug is broad ajiically ; tarsal segments 3 ami 4 not twice as long as 

 liroail : ]iulvillus and paronyciiiiim jiresent, the latter with two lobes at each side, 

 tlie ventral lobes broader ; Ibretibia icith a thorn at the end ; spurs very short, two 

 ])airs close together on hindtibia, the longer terminal spur little longer than the 

 tibia is broad. Wings entire, falcate, apex jwintel, not sinuate between SC and 

 SC'' ; D'' of forewing shorter than D' ; K- of hindwing central, or a little beiiind 

 centre of cell, D- slightly enrved or straight, 1)' twice as long as D', lower angle of 

 cell almost UO", sometimes obtuse ; frenulum and retinaculum present. No friction- 

 scales on clasjier and eighth tergite. 



Larva as in Amph/pterus, with white dorso-lateral line. — Food-plant : O/'eo-

Pupa not described in detail ; head with two tuliercles, tongue-case not reaching 

 end of wing-cases.

tj?. Individually variable in the markings. Frons nnicolorous, e.xcept a dot 

 at each side which is white like the terminal surface of the palpi. Mesothoracic 

 tegula without a grey fringe })osteriorly and laterally. Abdomen with a dark 

 mesial line, which is mostly interrupted on each segment ; eighth tergite of S 

 without patch. Tibiae with a white basal spot. Hindwing, near anal angle, with 

 a double spot of ovate scales whicii fall off easily, leaving the spots naked and 

 therefore transparent. 



On examining a series of specimens we come to the conclusion that the 

 differences pointed out by Kirby (see below) between b/ci(his, eo-i and titlioiris arc 

 not specific and not constant. But the Argentinian individuals and those from 

 Uruguay and neighbouring districts differ on the whole somewhat from the examjdes 

 found in the 2>rovinces of liio de Janeiro and Espirito Sauto, and must be kept 

 apart as a separate subspecies until it is ])roved, on receipt of more material from 

 the province of Rio, that the apparent differences are merely individual, not being 

 met with in the greater proportion of the individuals. 



cj. Eighth sternite faintly lobed mesially. Tentli segment essentially the same 

 as in Protamhidj/x and AmpliiptevuH ; sternite shallowly sinuate, sides rounded, 

 the spinose area more extended than in Amph/pterus. C'lasper sole-shaped ; harpe 

 (PI. XXXI. f. 6) with a broad and rather high submesial ridge {pm) wiiich inclines 

 distad, the distal process (pi:) very feeble, scarcely separated from the clasper. 

 Penis-sheath (PI. XXX. f 20) resembling that of Amjili/pfcfUfi, the carina terminally 

 fused with the membrane of the duct. 



?. Vaginal plate not strongly chitinised, Ijroadly rounded distally, no special 

 armature at orifice.
