OP PHILADELPHIA. 21 



impressed lines which are abbreviated by a submarginal im- 

 pressed line, two abbreviated lines before ; head, posterior edge 

 transversely rectilinear, angles extended backward abruptly, and 

 subacute ; rostrum rather short ; palpi oval-orbicular. 



Found in the Southern States ; the color is reddish or ferru- 

 ginous, with acute black lines. 



5. I. VARIABILIS. — Body oblong-ovate, gradually attenuated 

 before; sides hardly arquated ; a few remote, deeply impressed 

 punctures not more numerous behind ; posterior margin with 

 about twelve impressed, abbreviated lines ; a lateral, impressed, 

 punctured, submarginal line, obsolete behind ; two deeply in- 

 dented, abbreviated lines before ; head, hind edge rectilinear, 

 angles abruptly a little extended backwards," acute ; rostrum 

 rather short ; palpi ovate j color reddish or ferruginous varied 

 with white, incisures of the feet white. 



Very much resembles the preceding in form ; the white of the 

 back is more or less reticulated, and the [78] feet arc white 

 above, or only their joints. May not this be /. Ihieatus, if so, 

 my name must of course be rejected. 



6. 1. PUNCTULATUS. — Body oblong-ovate, gradually attenuated 

 before, sides hardly arquated, crowded with impressed confluent 

 punctures ; thorax destitute of punctures, but with two impressed 

 undulated lines ; abbreviated lines of the posterior margin not 

 deeply impressed, almost obsolete ; lateral submarginal line 

 deeply impressed, obsolete behind ; head, hind edge rectilinear, 

 angles abruptly a little projected backward, acute; rostrum rather 

 short; palpi oval; eyes distinct, impressed: color ferruginous, 

 thorax white lineated or varied with ferruginous, incisures of the 

 feet white. 



Considerably like the preceding.

 thorax blackish-oval, well defined, with numerous punctures; ter- 

 gum, punctures sparsate, and four or five blackish, obsolete, di- 

 lated radii on the disk ; a deeply indented .submarginal line ; no
