68 LEPIDOPTERA HETEROCERA 
apex not pronounced, termen (except in discolor) rounded. tornal area more or less produced, inner 
margin sometimes concave near tornus, leaving a conspicuous rounded tornal lobe, cell rather short, 
DC? and DC? usually separately incurved, resulting in an angle at origin of R?, C approximated or 
parallel to cell to almost one-half, then rapidly diverging, SC? separate, R? from considerably above 
middle, M! separate. c genitalia with uncus bifid, widely separate at the base, gnathos with long blunt 
tip. harpe simple with sacculus, penis pestillate, coremata present (rafflesii). 
Early stages unknown. 
"This has always been accepted as a natural genus, but it is doubtful whether. upon a survey of all 
the material, it should not rather be treated as a section of Hiffarchus. The shape, which is the most 
obvious distinction in the typical sections, is inconstant; thus species no. 6 to 8 of Tanaorhinus (Mixo- 
chlora, Warren, indescr.) have the forewing scarcely more falcate than Hfparchus (Loxochila) smaragdus. 
'The palpus, though typically longer in Tazaorhinus, is in like case; some species of Hifparchus (Megalo- 
chlora) approach the less extreme species of Tanaorlinus. The exact extent of the antennal pectinations, 
though it has been used by Meyrick as generic, in separating 7/ipfarclus 1) from Megalochlora, seems to 
us much too slight a distinction; moreover, the pectinations reach somewhat further (to almost two- 
thirds) in the Mixochlora-section than in typical TanaorAimus, and less far in most sections of Hifparchus 
than in the tvplcal one.
