CONTRIBUTIONS TO A KNOWLEDGE OF THE SUB- 

 FAMILIES OENOCEBOMINAE AND EEMITEEINAE 

 OF. GEOMETBIDAE. 



By LOUIS B. PROUT, F.E.S. 



''r^HE Geomotrid snlifarnilies treated of iu this j)aper have already undergone 

 •L a preliiuiiiar}- revision at my hands {Genera Iiifertonim, fasc. 104, lOln, and 

 129, 1912), but insufficiency of material, lack of time or occasion for real mono- 

 jj;raphic work, and various other circumstances made it impossible to avoid a 

 number of uncertainties and even errors in matters of detail. Moreover, manv 

 new species and forms have recently been discovered, in ])articular among a rich 

 collection made at Mt. Goliath, SiJOO — T^OO ft., Central Untch New Guinea (about 

 139° E. long.), by Mr. A. S. Meek. I therefore take this opportunity not only to 

 describe the novelties but also to introduce various notes and corrections concerning 

 earlier work. 



As I hope shortly to publish a catalogue of the lleinitlieinae in the " Lepi- 

 dopterorum Catalogus," it is not necessary here to refer to discoveries of synonymy 

 which need no particular comment, nor to give a list of the new .sjiecies wliicli have 

 been published since the api)earance of my work on the " (xenera Insectorum" ; but, 

 with these exceptions, I shall endeavour to bring our knowledge us nearly as 

 possible up to date in all essentials, deeming it a manifest advantage to have the 

 whole within the same covers rather than spread over a number of detached notes. 

 For this reason no fannistic limits have been prescribed, althougli tlie New Guinea 

 (icometrids claim by far the largest share of attention. 



SuMFAMiLV OENOCHROMINAE. 

 1. Dichromodes semicanescens spec nov. 



?, 18 mm. Head, with face, fuscous sprinkled with grey. Palpus fuscous, 

 whitish at base. Thorax and abdomen concolorous with wings. Fore and middle 

 legs and hiudtarsus fuscous on upper side, narrowly pale-belted. 



Foreu'iiuj rather short and broad, apex not acute, termen bowed, not stnnigly 

 oblique ; mostly grey in basal jiart, cell and entire area posterior to M and M-, 

 with coarse fuscous irroration ; basal part of coll and of costal area slightly mi.xed 

 with light ferrnginous-ochreons ; stronger longitudinal patches of the same distally 

 to cell, placed between SC' and R- and between R^ and M", reaching as far as a 

 dark fuscous border, which runs from costa to tornus, abont 2 mm. wide anteriorly 

 lint narrowing to a point at tornus ; first line fine, dark fnscous, indistinct, from 

 a thick black spot at one-fourth costa ; a thick black costal spot proximally to 

 cell-spot, another distally to it ; cell-spot black, continued with fuscous posteriorly 



along DC ; postmedian line scarcely traceable. Hindwing uniform fu,scons, only 



the inner margin slightly ])aler, with indications of beginnings of lines. 



Underside shining greyish fnscous, forewing only with somewhat darker border, 

 hindwing with rather more brown tinge, rather less shiny, a dark discal spot and
