canal system with strong cuticular walls, or a mass of trabecular cuticular bars leaving openings between 

 themselves. In the figures this mass is indicated as the proximal part of the root system. From this 

 proximal part of the root system a large branch extends to the left (to the right in the figure), and

at its end this branch divides into smaller roots which in the section of the figure show their cuticular 

 walls only. Another branch of the proximal root system is to be seen directly under the main mass. 

 This branch consists of cuticular matter with very small openings. A third branch of the proximal root 

 system, is visible in the lower part of the figure. In this branch the openings are large in comparison to 

 the cuticular matter. The figure further shows some roots with thin walls (though drawn with rather 

 heavy lines) in the vicinity of the antennal gland, at each side of the median plane.
