SPOLTA ZEYLANICA. 
IV. and V. very near together below the same, and VI. with two 
hairs directly under these. On the base of the prolegs stand also 
two warts, one exterior (VII.) and one interior (VIII.). 
“ On the ninth abdominal segment I could only make out four 
warts on each side : two dorsal ones one behind the other, and two 
lateral ones one above the other. On the second and third thoracic 
segments warts I. and II. stand one above the other, each composed 
of two small single-haired tubercles on a single somewhat large flat 
chitinous shield (l.a and 1.6, Il.a and II.6, according to Dyar); then 
follow more distantly below and anteriorly (in the case of grammo- 
dactyla), 111. and IV. likewise one above the other, and still further 
down comes VI. Wart V. seems to be absent. In Orn. 
hexadactyla III. and IV. stand horizontally riear one another, V. is 
wanting or is extremely rudimentary. 
“ The first thoracic and the tenth abdominal segments are pro¬ 
vided with weak circular chitinous plates (thoracic shield and anal 
shield), and are furnished with numerous small-haired warts.

OtneocUcL larva. 
“ The thoracic legs are of the usual pattern, generally weakly 
chitinized. The prolegs are completely developed circle-feet; on 
the anal claspers the hooks form a semicircle open posteriorly. It 
is very noteworthy that in very young larvae the prolegs and anal 
legs are wholly without hooks. 
“ The larvae are unicolorous, yellowish or reddish-white, without 
markings; before pupation they often assume a reddish colora¬ 
tion.” 
The accompanying sketch (Fig. 2), which must be taken to give a 
general idea of an Orneodid larva rather than that of any particular 
species, has been drawn partly from descriptions, partly from pre¬ 
served larvae received from Herr A. Bang-Haas, and partly from 
microscopic preparations of larvae of 0. hexadactyla kindly lent by 
Dr. T. A. Chapman. 
Pupa. 
In their pupal state especially the Orneodidae are seen to be 
strikingly distinct from the Pterophoridae, with which group, as
