122 MR. F. WALKER ON HETHROCEROUS LEPIDOPTERA 
oblique; 4th superior vein very far from the others, which are ap- 
proximate; 3rd inferior vein about twice as far from the 4th as from 
the 2nd; 2nd a little nearer to the Ist than to the 3rd. Hind mE 
with one superior vein. 
This genus has a very peculiar structure ; it has some resemblance to Nu- 
daria, but its affinities are uncertain. Type C. trichopteroides. 
131, CHAMAITA TRICHOPTEROIDES, n.s. Mas. Cinerea, antennis 
albidis, alis fere hyalinis vix pubescentibus.

and very short pubescence ; veins pale. Fore wings with the costa

132. CHAMAITA CRASSICORNIS, n.s. Mas. Alba, palpis porrectis 
brevissimis, antennis robustis subsetulosis basi crassis, alis fere hya- 
linis vix pubescentibus. 
‘ Male. White. Palpi porrect, very short. Antenne stout, minutely 
setulose; basal joint thick, rather long. Abdomen with two long

Inhabits also Hindostan and Java. 
Gen. Numenes, Walk. 
This genus has perhaps more affinities with the Drepanulide and with 
the Bombycide than with the Arctiide, but hardly accords with any of the 
families of the Bombycites. 
135. NUMENES CONTRAHENS, n.s. Mas. Testacea, capite thorace 
pedibusque anterioribus fuscis, alis anticis vitta postica fasciisque dua- 
bus fuscis, posticis luteis fascia marginali fusca. 
Male. Testaceous. Head, thorax, and anterior legs brown, hirsute. 
Proboscis obsolete. Palpi porrect, stout, short, pilose. Antenne 
short, very deeply pectinated. Abdomen, hind legs, and hind wings 
pale luteous. Wings ample. Fore wings slightly acuminated, with 
a brown stripe along the interior border, and with two brown parallel 
and nearly upright bands ; 2nd band irregularly double except in front. 
Hind wings with a brown marginal band, which is irregularly exca- 
vated in front. Length of the body 7 lines; of the wings 18 lines. 
This is quite distinct from the typical species, N. Siletti, which it much 
resembles in colouring and in markings,
