Not previously recorded from Ceylon. The specimen differs 
from Cameron’s description in having the head finely and sparsely 
punctured ; the tibize, as well as the tarsi, are testaceous, also the 
mandibles and the six basal joints of the antenne. The thorax 
is distinctly more slender than in Cameron’s figure, especially the 
median segment ; but this may be an error in the figure. The size 
as in Cameron’s description is 5 mm. 
This seems to be the first authentic record of Methoca from Ceylon, 
for M. rugosa, Cam.. does not belong to the genus. ;

Male specimens from Colombo taken in June are rather smaller 
than the type, measuring only 9 mm. in length. The female varies 
much both in the closeness of the puncturation and the colour of the 
wings, and there is also much difference in the comparative length 
of the abscisse of the radius. It is quite possible that two species 
are represented in the series, but I can find no constant distinguish- 
ing character. Some of the specimens are almost identical with 
Myzne claripennis, Bingh. The differences do not appear to be 
seasonal.
