Euhomalocera, new genus 



Head with face smooth (vertex rubbed). Proboscis developed. 

 OceUus apparently absent. Antenna in male about 1, minutely 

 ciliate, flagellum strongly laterally compressed, ribbon-Uke, broad, 

 gradually narrowed toward extremities, scape normal, wdthout pecten. 

 Labial palpus rather short, curved, subascending, slender; median 

 segment sHghtly thickened with scales, roughish along lower edge, 

 terminal segment slender, smooth, acute, shorter than median. Maxil- 

 lary palpus minute, vestigial, appressed to proboscis. Posterior tibia 

 with slightly raised bristly hairs in middle above, tarsus with bristly 

 hairs above. 



Forewing lanceolate, aU veins present, lb very short-furcate at base, 



2 and 3 stalked from angle, 7 and 8 stalked, stalk 1/3, 7 to costa, 11 

 from beyond middle of cell. 



Hindwing sublanceolate, pointed, termen straight above, gently 

 rounded below; about 1, cilia under 1. Vein 2 from well before angle, 



3 and 4 stalked from angle, 5 parallel, median discoidal obhterate, 6 

 and 7 long-stalked. 



Male genitaUa of the type of Promalactis Meyrick; as described 

 under the species below. 



Type species: Euhomalocera heliosema, new species. 



Seemingly a near relative of Narthecoceras Meyrick from India, 

 which has similarly flattened and ribbon-lilce antennae. The dif- 

 ferences of external structiu'e are much shorter palpi, and the semioval- 

 lanceolate hindwing with veins 3 and 4 stalked (in Narthecoceras 

 connate). In addition the type species has a rather different facies — 

 that, in fact, of a HeUodinid. 



The genitalia certainly suggest a relationship either with Xylory- 

 ctidae or with Oecophoridae.
