Explanation of Plate XXVII. 



(To be bound facing Plate XXVII.) 

 Fig. 1. Spiracular area of 5th and 6th abdominal segment x 75. To the 

 left are various spiculate hairs, not very different from the "fungus" hairs of 

 Chrysophanids. 



Fig. 2. Third abdominal spiracle x 150, shows the abundant lenticles, and 

 how these and the hairs are not in line with the reticulations, whilst the "rosettes " 

 are at the angles of the reticulations, there are only one or two rosettes in this 

 figure ; there are more in Fig. 1.
