June 13, 1910.] Description of Indian Micro-Lepidoptera, 167 
beyond second ; a more or less developed sometimes interrupted similar streak 
along posterior half of submedian fold ; a somewhat darker curved subterminal 
line, on which the veins are indicated by scattered dark fuscous scales ; a series 
of cloudy dots of dark fuscous irroration round apex and termen: cilia light 
brownish sprinkled with darker, towards tips sprinkled with whitish, Hind- 
wings pale fuscous, darker posteriorly ; cilia pale fuscous, with darker subbasal 
line. 
Simla ; in August, three specimens. Lerhaps nearest veneficella, 
~ Tonica, Walk. 
This generic name supersedes Binsiita, Walk. 
Tonica niviferana, Walk. 
Peradeniya, Ceylon ; Karwar, Bombay, Calcutta, Sikkim, The pupa of this 
and the next species stands erect on its tail, and imitates the head of a small 
snake (Maxwell). 
Tonica teratella, Walk. 
(Tonica terasella (prav. form.), Walk., Cat. XXIX,, 788,) 
Karwar (Maxwell) ; Sikkim ; in July. Also from Borneo, 
Tonica zizypht, Staint. 
(Depressaria zizyphi, Staint, Trans. Ent. Soc., Lond, (n.s.), V., 115 ; D. angusta 
Wals., Moore, Lep. Ceyl. III., 508, pl. 209, 5. 
Maskeliya, Kegalle, Puttalam, Ceylon ; Palni Hills ; in October, Stainton’s 
type was from Calcutta ; it was bred from Zizyphus jujuba. 
Protonostoma, n. g. 
Head with appressed hairs; ocelli present ; tongue developed. Antenne j, 
in @ serrate, minutely ciliated, basal joint moderate, without pecten. Labial 
palpi very long, recurved, second joint with dense appressed scales, terminal 
joint shorter than second, moderate, acute. Maxillary palpi short, distinct 
porrected. Posterior tibie shortly rough-scaled above, Forewings with 2 
from angle, 7 and 8 stalked, 7 to termen,11 from middle. Hindwings 1, ovate, 
cilia } ; 3 and 4 connate, 5-7 parallel. 
I consider this genus must approach very near the primitive form of the 
Gcophoride, from which the whole of the remainder could theoretically be 
derived. It has also marked affinity with the Plutellidw,and indicates their 
probable origin from that family. The labial palpi, neuration, and superficial 
characters are of clear @cophorid type, On the other hand the maxillary palpi 
are distinctly of Plutellid type,and I have not observed any similar in the 
Ocecophoride ; the shortness of the cilia of hindwings, and apparent absence of 
long hairs ‘on posterior tibie (these last are more or less damaged, and the 
structure is not quite clear) are also Plutellid characters, Superficially the 
species is very similar to Hypercallia pyrarcha described above. If the genus 
is regarded as primitive, then it might have given rise through Cryptolechca to 
the Depressariad subfamily, and through Hypercallia to the Oecophorid sub= 
family. This solution would apparently satisfy all conditions of the problem 
known to me at present,
