of the body it is clearly evident that these appendages are dorsal 
and not ventral as one might naturally suppose from analogy 
with other insect larvae. Laterally nine small circular spiracles 
form a continuous series from the mesothorax to the seventh 
abdominal segment. Scattered over the body are a number of 
very minute spiniform black tubercles from the apex of some of 
which there projects a h}^aline seta. Most likely all the spines 
bear setae in perfect specimens; they are arranged as follows: 
prothorax with a transverse ring of twelve; meso and meta- 
thorax with a ring of ten, interrupted above; first abdominal 
segment with one above the spiracle and a series of three below; 
second to sixth with one above and two below; seventh and 
eighth with only two on each side although the eighth bears sev- 
eral other round chitinized dots; apical segment with a ring of 
about ten. In addition the head bears a seta, without tuber- 
cle, at each side of the front and one on each cheek. 
The pupa is similar in general form to the imago and the 
body, including the head, bears a few scattered long bristly 
hairs. It is nowhere noticeably tuberculate except that behind 
each antenna there is a lanceolate projection that represents in 
exaggerated form the carina behind the eye of the adult. Above, 
the head is bilobed, due to a deep median impression, but the 
surface of each lobe is evenly convex and shows no trace of the 
spiniform porcesses of the imago. The anterior margin of the 
pronotum has a median tubercle which is crowned at apex with 
a tuft of sparse, short bristly hairs. This no doubt is a functional 
pupal organ, the vestige of which persists in the imago as the 
median pronotal projection or tooth described on a previous 
page. Seven pairs of abdominal spiracles are visible, each 
deeply pigmented, entering the tracheal trunks by more weakly 
pigmented funnels. 
So far as I can ascertain, the only reference to any larva 
similar to the one just described, relates to Axima which is said 
by Howard ( loc . cit.) to have “six or more strong dorsal tuber- 
cles. ” According to the same author the pupa of Axima has 
the head strongly tuberculate which is not the case in Conoaxima, 
except for the lamelliform projections on the temples.
