differences are more than can be expected between varieties; and the 

 two {tdleana and ochreicostana) must be held as distinct species. 



The type of taleana (or what remains of it, two detached fore wings 

 on card mounts) is in the Fernald collection of the United States 

 National Museum, and not in the British Museum as I had written.*

The acquisition by the United States National Museum of the 

 Fernald collection has enabled me to make a genitalia slide of the 

 type and only available specimen of this species, and to place it 

 where it properly belongs, in Hystricopliora rather than Ancylis. In 

 pattern and coloration it fits nicely with taleana, ochreicostana and 

 decorosa, the four forming a compact group of similarly marked but 

 very distinct and easily recognized species. 



HYSTRICOPHORA DECOROSA, new species 



Figures 25, 28 



Similar to the foregoing but much darker, with more restricted 

 orange-yellow costal marking, differently shaped unspined tergite of 

 eighth abdominal segment (compare figs. 26, 28), and differently 

 shaped harpes. In loricana they are symmetrical and the ventral 

 element of the divided harpe is very broad (roughly triangular) while 

 in decorosa they are asymmetrical and the ventral element is very nar- 

 row and elongate (compare figs. 24, 25). 



Antenna with basal joint black; ocherous beyond. Palpus sordid 

 ocherous, shading to fuscous at apex. Head, thorax, and fore wing 

 semilustrous blackish fuscous; on costa of fore wing near apex a 

 conspicuous triangular orange colored spot, bordered inwardly by a 

 narrow dull metallic band extending from outer fourth of costa to 

 termen below apex and broken by three pale costal dashes inter- 

 spaced with black; the two inner dashes sordid whitish ocherous and 

 the apical dash clear white; a somewhat larger orange blotch occupy- 

 ing area between ocelloid patch and termen; ocelloid patch consisting 

 of two short black dashes between two short obscure metallic vertical 

 bars; termen edged by a fine black line; cilia lustrous, dark, nearly 

 concolorous with ground color of wing. Hind wdng concolorous with 

 fore wing; cilia but very little paler. 



Harpes of male genitalia and tergite of eighth abdominal segment 

 figured from type.
