A rather small genus, ranging through the Indo- 

 Malayan region, Australia, and the Pacific Islands ; one 

 species extends into Eastern Siberia. I have given it 

 previously the name of Semioceros, but now recognise 

 that Walker's name should be adopted. The genus is 

 one of a small group, all having tufted antennae in the 

 S , and originating probably from Metasia. 

 fenestralis, Christ. (Agrotera). 



36. DiASEMiA, Hb. 

 Face rounded ; ocelli distinct ; tongue developed. Antennae 

 three-fourths, in g- filiform, ciliated with fascicles (1^ — 2). Labial 

 palpi moderately long, porrected, second joint with dense pro- 

 jecting scales, terminal joint moderate, exposed, tolerably cylin- 

 drical, pointed. Maxillary palpi moderate, porrected, apex loosely 

 penicillate. Abdomen in (^ with slender anal tuft. Posterior 

 tibiae with oiiter spurs one-half to two-thirds of inner. Fore wings 

 with vein 7 from near 9, 8 and 9 stalked, 10 closely approximated 

 to 9 towards base. Hind wings over 1 ; veins 3, 4, 5 approxim- 

 ated at base, 7 out of 6 near origin, anastomosing with 8 to one- 

 third. 



A very small but quite c osmopolitan genus, allied to 

 Metasia.

37. DUPONCHELIA, Z. 

 Face rounded ; ocelli distinct ; tongue developed. Antennae 

 three-fourths, in ^ filiform, shortly ciliated {^). Labial palpi 

 moderate, ascending, second joint with dense projecting scales 

 beneath, terminal joint rather short, cylindrical, exposed. Maxil- 

 lary palpi short, apex loosely penicillate. Abdomen in ^ very 

 long, anal segment elongate, with exsertible genital tuft. Posterior 

 tibiae with outer middle-spur in ^ one-fourth, in 5 one-half inner. 

 Fore wings with an upward-tui'ned ridge of scales from vein 1 near 

 base beneath, 7 from near 8, 9 and 10 out of 8 ; in ^ with a naked 

 irregular indentation in cell beneath, and a small indentation 

 between 7 and 8 at base, 2 almost from angle or out of 4, 3 and 4 

 stalked. Hind wings 1 ; veins 3, 4, 5 closely approximated at base, 

 7 out of C near origin, anastomosing with 8 to two-fifths. 



Allied to Diasemia ; the single species is South 

 European. Zeller's genus was published in 1847, and
