LEGS IN THE CARABID^. 



By Howard Notman, 

 Brooklyn, N. Y. 



The coxae of the anterior and intermediate legs are globular in 

 form and exhibit the same structure throughout the Carabidse. The 

 apex or upper end of the joint, viewing the beetle as it lies on its 

 back, contains a circular cavity which holds the condyle of the tro- 

 chanter. Adjoining this cavity on the outer side is another cavity 

 or depression in the outer face of the coxa. This second cavity 

 reaches the outer edge of the joint and is bounded by a more or less 

 carinate edge except at the outer end where the carina is obliterated. 

 Where the two adjoin, the wall of the central cavity is deeply emar- 

 ginate. This structure gives the leg a greater radius of transverse 

 motion and allows it to be drawn closer to the body in repose. 



The anterior and posterior edges of the outer depression are not 

 similar in form. The former, viewed from the front, is straight and 

 continuous with the edge of the central cavity. The latter, viewed 

 from the opposite direction, is strongly concave and elevated in a 

 prominent blunt-pointed tooth where it joins the edge of the central 

 cavity. This tooth is bent slightly over the condyle and strengthens 

 the hold on the latter at the point where the emargination between 

 the cavities tends to weaken it. Considering this to be a description 

 of the anterior coxae, the arrangement in the intermediate is exactly 

 the reverse; that is, the tooth is on the anterior edge and the poste- 

 rior edge is straight. When it is considered that the anterior legs 

 are used chiefly to pull the beetle forward and the intermediate to 

 push it in the same direction, the reason for the opposite arrange- 

 ment is explained and it seems probable that the tooth not only
