OF PHILADELPHIA, 178 



This species very mucli resembles the preceding, but is larger, 

 black, and tbe thoracic scales are orbicular, exactly closing the 

 dilated punctures like opercula.

FALCIGER Meg. Dej. 



1. F. ACEPHALUS. — Blackish, spotted with cinereous; thorax 

 with an impressed line, an obtuse tubercle on each side.

 spotted and varied with cinereous, imbricate : head, when at rest,

The variety occurs in Pennsylvania. A diflferent species, 

 which I have named 4:-spmosus, inhabits this State, remarkable 

 for its similarity to the acephalm, but it may be immediately dis- 

 tinguished by the armature of two upright spines on the anterior 

 edge of the thorax.
