GENUS NOTASPIS. 349 



the undermentioned spine, gives off a single similar 

 spike, but smaller, just as is the case in the nymph of 

 T. dentatus. From the central lobe of each projection 

 springs a very long and large spine ; those on the first 

 (or central) pair of projections on the progaster are 

 deeply serrated, or slightly spinulated, and curve 

 forward and somewhat outward ; those on the second 

 pair are straight, slightly spinulated, and directed 

 obliquely forward and inward ; those on the antero- 

 lateral angles are directed forward and outward, and 

 bear numerous pairs or whorls of long sharp spinules, 

 which diminish gradually in size ; those near the 

 proximal end of the principal spine being much longer 

 than those at the distal end ; the former have a decided 

 tendency to be recurved. The spines on the projections 

 further back are mostly doubly curved (line-of-beauty- 

 shaped), are directed backward and outward, and have 

 spinules similar to those last described. The posterior 

 pair of spines curve backward. The ventral surface 

 is rough and lined, the genital and anal plates almost 

 touch. 



Distribution. — This species has hitherto only been 

 found (by myself) at the New Forest, near Lyndhurst, 

 on oak-trees.
