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 l)lack tubercles from the apex of some of 

 which there projects a hyaline 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 bristlj^ 

 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. cii.) 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.
