Fonte Boa, Upper Amazon, May 1906 (S. M. Klages) ; type 3 and an- 

 other in coll. Tring Museum. St. Jean de Maroni, French Guiana, July; a <? 

 in coU. L. B. Prout. 



30. Ptychopoda combinata spec. nov. 



1^ ?, 20-26 mm. Face red-brown, mixed (except below) with blackish. 

 Palpus ochreous, on outer side mixed with red-brown and black. CrowTi creamy 

 white, narrowly edged behind with black. Antennal shaft ochreous, the first 

 few joints white ; ciUation even, scarcely longer than diameter of shaft. Collar 

 orange. Front of thorax vinaceous, mixed with orange-buff ; thorax and 

 abdomen otlienvi.se concolorous with \\ings, the abdomen v,ith two or three 

 blackish medic-dorsal spots, on the middle segments. Hindtibia in S rela- 

 tively long, dilated, with long hair-pencil from base ; tarsus strongly abbreviated. 



Foreunng with areole rather small, all the subcostals well- or long-stalked 

 from its apex ; dirty white, with salmon-buff and sparse vinaceous and black 

 irroration ; costal edge narrowly orange-buff ; markings salmon-buff, almost 

 entirely overlaid with black, consisting of large spots much as in Pt. complexaria 

 Schaus {Tr. Amer. Ent. Soc. xxvii. 257) ; antemedian spot in cell rather small, 

 that behind it large, somewhat crescentic, but broad, its convex side turned 

 towards the base, that at hindmargin .small, obhque ; median series similar, 

 but the first two larger, the one in (at end of) cell posteriorly confluent with a 

 narrower extracellular mark, behind which (at base of R' — M' and between the 

 medians) stand two small lunules ; postmedian fomied abovit as in complexaria, 

 with rather marked proximal thickening between the radials and between M' 

 and SM', sUghter thickening between R' and M' and a thick dot or dash at 

 hindmargin ; beyond (leaving free a rather thick, sinuous pale hne) stands an 

 irregular row of elongate interncural dark marks between R' and hindmargin, 

 the first two and last three wedge-shaped, those between R' and M^ larger and 

 broader ; subterminal line zigzag, white, rather thick, bounded proximally by 

 these spots ; a rather thick lavender Une at termen ; fringe pinkish proximally, 



yellow distally. Hinclwing ample, with termen evenly rounded ; 8C' — R' 



quite shortly stalked ; to bej'ond the postmedian Hne white, with rather sparse 

 irroration, distally more buff, with strong irroration ; a minute but distinct 

 cell-dot ; Hnes very fine and indistinct, shaped as in fervens Butl. {Tr. Ent. Soc. 

 Land. 1881, p. 340) ; subterminal line weak and interrupted anteriorly ; terminal 

 and fringe as on forewing. 



Underside whitish, with more or less strongly ochreous veins, costal and 

 distal margins and fringes, the costal margin of forewing rather broad, more 

 reddish proximally ; forewing wth the spots showing through in grey and with 

 the anterior part of an ochreous postmedian Une. 



Surinam : Aroewarwa Creek, Maroewym Valley, July 1905 (type), March 

 and April 1905 (S. M. Klages) ; French Guiana : St. Jean de Maroni; Upper 

 Amazon : Fonte Boa, May and July 1906, Codajas, April 1906 (S. M. Klages) ; 

 aU in coll. Tring Museum. 



Strongly recalls complexaria Schaus, in which, however, the termen of the 

 hindwing is irregularly bent, whereas in the present species it is at least as regular 

 as in fervens Butl.
