Additional localities —Canara District, on the Goa frontier, 
India (E. H. Aitken); Kuala Lumpor, Malay States (Dr. 
Durham). 
Observations.—In some specimens the legs seem quite as 
described by Van der Wulp—“testaceous.” The prothoracic 
lobes, I find, have dense tufts of large black scales projecting 
forwards. The abdomen has a dense tuft of black scales on the 
apex of the venter. The apical costal spot is to some extent 
carried across the apex of the wings as a pale band. 
The larva and its habits —The larva differs from M. sinensis 
only in the shape of the frontal hair-tufts, and it has also a 
branched lateral antennal hair. The frontal hair-tufts are more 
regular than in sinensis, and are composed of a number of radi- 
ating hairs (fig. 4, f) on each outer side and a median single pair. 
It is usually dark in colour, with a light collar and a light band 
at the third abdominal segment, most prominent in the young. 
Sometimes there is a broad silvery dorsal stripe. 
‘‘ But colour is a very unsafe guide,” writes Mr. Aitken of 
this larva; “form and habitual attitude can be trusted, and, in 
the case of barbirostris, serve to distinguish it almost at a glance 
from all the larvae of Rossii type. The thorax is small, scarcely 
exceeding the head in breadth, the head is elongated, and the 
abdominal segments are nearly equal, so that the insect looks 
long and worm-like when compared with the larvae of Rossii. 
This appearance is enhanced by its attitudes, which are less 
rigid even when it is floating at rest. When browsing on 
confervae, which appear to be its principal food, it les like a 
snake. It appears to feed very little on the surface. I found 
this species in a rocky pool in one stream, and amongst dense 
grass and weeds in another.” 
The palmate hairs are shown in fig. 25, 1, p. 47.
