The above figures show the very great variation in size to be found 

 in both sexes. 



Neither larva nor pupa appear to have been previously described. 

 Larva (almost half-grown). — General tint, a dark flesh colour 

 with brown head, yellow prothoracic segment edged in front with black 

 with a few black specks behind ; canary-yellow mesothorax and flesh- 

 coloured metathorax. Following eight segments are flesh-coloured, 

 lighter at junction of segments. Last segment is canary-yellow, becom- 

 ing orange-yellow at extremity. 



The head is dark chestnut-brown anteriorly, shining, chitinous, 

 ovate, and large ; mouth parts black, antennae short, 3- jointed, yellow- 

 brown. Posteriorly head shades off into pale-brown and yellow. It is 

 followed by a large prothoracic shield which is hard and chitinous and 

 shining, slightly convex. The chitin terminates at the sides, the under- 

 surface of prothorax being canary-yellow in colour and soft. The large 

 chitinous shield is ovate, anterior margin straight, posterior ovate » 

 elliptical. At the posterior edge of the thoracic plate is an elliptical 

 circle of small raised spikes or spade-like protruberances, doubtless used 

 to shovel out of the way wood refuse and perhaps for scraping purposes* 

 They are set backwards and are club-shaped. Behind these are a num- 

 ber of minute black spots placed in a crescent-shaped manner on the 

 mesothorax, the angles pointing forwards. The mesothorax is much 

 narrower and smaller and with a quite soft skin. The following seg- 

 ments are equal in size, about a third less in diameter than the prothorax, 

 and have a few scattered black tubercles on them, each bearing a thin 

 white hair. The last segment tapers to a blunt point. 



Mouth parts pale-yellow beneath. Thorax beneath dark canary- 

 yellow and rest of segments dark-yellow. Thoracic legs canary-yellow, 

 pro-legs dark-yellow, flat and thick. Length Ij inch. 



Fujpa. — Sub-cylindrical, stout. Dark chestnut-brown to almost 

 black. Black ventrally. Segmental bands orange, as also is front of 

 thorax. Wing covers, eyes, antennae and legs well marked on outeJ
