119. Tricentra flavimarginata sp. no v. 



Forewings : deep vinous red, dusted with, darker ; blackish along basal half of 

 costal area and along hindmargiu ; a blackish line at one-fourth of costa to oue- 

 fourth of inner margin, angnlated outwards in cell ; a blackish crenulated line 

 outcurved from two-thirds of costa to snbmedian fold, then vertical to inner margin 

 at three-fourths ; a subdentate blackish submarginal line parallel to the last ; hind- 

 margin with the fringe bright j'ellow, except at extreme apex and at the bend at 

 vein 3, where the blackish scales extend across the fringe ; two small white cell-dots 

 on the discocellular. 



Hindwings : simOar, but the yellow margin hardly interrupted, the edge of the 

 dark marginal area irregularly creunlate ; cell-dots as in forewings. 



Underside paler and duller ; a i)ale streak on discocellular. Thorax and 

 abdomen duU vinous red ; shoulders blackish ; head damaged, but apparently black ; 

 antennae red. 



Expanse of wings : 19 mm. 



One <? from Paramba, Ecuador, Jan. to May 1897. 



Superficially somewhat recalling a Chrysocraspeda. 



Xenostigma gen nov. 



Like Anisodes in shape and markings of wings, but the palpi more like those 

 of Hetcrephgra ; second joint long, squamous, obli({nely porrect in front of face, 

 third joint minute, hardly visible ; antennae of S subserrate, with regular cilia ; 

 hind-tibiae and tarsi of S aborted, a long pencil of hair from the femoro-tibial joint. 



Neuration : forewings, cell abont half as long as wing ; discocellular somewhat 

 inangulated ; first median nervnle at four-fifths, second at seven-eighths ; radials 

 normal ; 7, 8, 9 stalked from well before end of cell, 10 a little before them, 1 1 from 

 one-half; 10 anastomosing with 11, and again with 8, 9, forming a double areole. 

 Hindwings with veins 3 and 7 close before angles of cell. 



Type : A', peiftisaria Wlk. {Ephyra, ?'). 



120. Xenostigma perfusaria. 



Ephgra ? perfusaria Wlk. xxii., p. 634. 



Walker's type is without head, and otherwise not in perfect condition. I have 

 therefore thought it useful to redescribe the species shortly from a fresh i , from 

 Ciudad Bolivar, Venezuela, May 18!I8 (Klages). 



Forewings : pale wood-colour, dusted with darker, and suffused towards hind- 

 margin with rufous ; first line at one-fourth, much outcurved, indicated by three 

 blackish dots on subcostal, median, and snbmedian veins respectively ; second line 

 from just beyond middle of costa to beyond middle of inner margin, also strongly 

 outcurved, jiarallel to first line, lunulate outwards ; third line at three-fourths, 

 marked by distinct black vein-spots, which represent the teeth of the deuticulations ; 

 submarginal line very obscure, preceded by a dark clond on costa, three confluent 

 blackish blotches between veins 4 and 7, and another at anal angle; an oblique 

 blackish triangular streak from apex to the subcostal blotches ; marginal lunules 

 distinct, black, with slightly paler edging; fringe concolorous, with black dots 

 beyond the veins ; cell-spot small, whitish, edged with rufous. 



Hindwings : cell-spot largo, oval, black-brown, with a few pale scales at centre,
