EUCOSMA MELANAULA, MEYR. (PLATE X, FIG. 1; anp PLATE XI.) 
Eucosma melanaula, Meyr., Exot. Micr., II, 17-18 (Oct. 1916)(’). 
Described from the Khasi Hills, Pusa and Coimbatore, and doubtfully 
from Java. “ Bred from larve feeding in flowers or pods of Cajanus indicus 
and Phaseolus mungo (Leguminose)’’('). We have it from Pusa, Chapra 
and Coimbatore. 
Eucosma melanaula, although only recently distinguished, is of common 
occurrence, probably throughout India, on various leguminous crop-plants. 
It has been found at Pusa on arhar (Cajanus indicus), wrid (Phaseolus radiatus), 
mung (P. mungo), moth (P. aconitifolius) and Florida beggar-weed, the larva 
boring into flower-buds, flowers, top-shoots and seed-pods. In the case of 
pods, the seeds are eaten, and, when top-shoots are attacked, the larva tunnels 
to some distance even in the case of thick stems, the stem being killed back 
and the top leaves also being webbed over and eaten. In the case of flowers, 
they are spun together with silk and the larva lives concealed amongst the 
spun-up flowers. It is at times a decided pest and seems to occur at any suit- 
able time of the year but in greatest numbers from August to October. 
The full-grown larva is about 11 or 12 mm. long and 1°5 to 2 mm. broad, 
moderately stout, somewhat compressed dorso-ventrally, sides of body nearly 
parallel, uniformly yellow, occasionally greenish; head shiny yellow, yellow- 
brown or occasionally blackish ; prothoracic shield unicolorous with head 
or paler ; body segments distinct ; tubercles show as somewhat shiny spots 
carrying thin hairs ; legs and prolegs normal, unicolorous with body, hooklets 
on prolegs brown and arranged in a complete circle.
