Fig. I. — Arenophilus bipimcticeps (Wood), dorsal view of the head with part 

 of the cephalic plate removed showing the cephalic nervous system. Note the 

 position of the cerebral glands (CGL) and the cerebral haemolymph vessel 

 (CBV). The latter is indicated by shading as emerging anterior to the crossed 

 tracheae (TR), which served as reference points in the reconstruction pro- 

 cedure. (Graphically reconstructed from transverse serial sections.)
