Campylarchis, new genus 

 Valva not thus 2 



2. Valva with base soldered to vinculum, cucuUus with a strong lateral clasping

3. Forewing with veins 8 and 9 separate Heterogymna 



Forewing with veins 8 and 9 stalked Meridarchis 



Campylarchis, new genus 



Head with appressed scales. Ocellus absent. Proboscis developed. 

 Antenna in male 3/4, filiform, ciliated, cihations over 1 ; scape elongate, 

 clavate. Labial palpus moderate, subascending, median segment 

 spindle-shaped, with closely appressed short scales, roughish below, 

 terminal segment about 1/3, spindle-shaped, subacute, slightly rough 

 (thorax rubbed). Posterior tibia with very long, fine hairs above. 



Forewing elongate-sublanceolate, dilated, pointed, 2 from toward 

 angle, 3 from angle, 4 and 5 connate, 6 remote, 7 separate, to apex, 

 8 and 9 stalked, 11 from 3/4 of cell. Hindwing semioval-lanceolate, 

 pointed, over 1, cilia 1/2. Vein 2 from 1/2, 3 and 4 stalked, from

Male genitaha. Tegumen small, rounded. Saccus developed, 3x 

 as long as tegumen. Valva strong, very short, sclerotized, sacculus 

 extended; cucullus small, hairy, with an additional, distal lobe. 



Type species: Campylarchis acuta, new species. 



The genus is very characteristic by reason of the male genitalia. 

 It is aUied to Xyloides Diakonoff and Metacosmesis Diakonoff, closer 

 to the latter but not very near. 



The following earlier described species also belong here judging 

 from Clarke's illustrations of their male genitaha.
