OF riirLADKT.rnrA. 147 



IJdilv blackish or dark rcddish-lirown, tinprod with brassy, punc- 

 tured : niaiulibk'S as Kjiij; as the head ; inner side witli a robust 

 emari^inate todth at base; an unarmed excavated interval in the 

 middle, and a dilated somewhat securiform tip, armed with about 

 six small teeth ; exterior ed^e with a rounded lobe at base, and 

 elevated angle near the tip : thorax margined, not distinctly sinu- 

 ous before the posterior angles : elytra punctured ; striae almost 

 obsolete and punctured : anterior tibia with more than ten inequal 

 very acute teeth. 



jjcngth two-fifths of an inch. 



^'cry clo.sely allied to LuriinnA luirahoidrs, and may pctssibly 

 prove to be only a variety of that species j but as far as I have 

 had an opportunity of comparing specimens, it differs from riira- 

 bouhs in color, in being rather more robust, and in being desti- 

 tute of the obtuse sinus or truncation near the posterior angles 

 of the thorax, which is observabK^ in that species. The mandi- 

 bles of the fciiiale are sliorter tlian those of the male, the inner 

 edge sometimes merely dilated and rectilinear, [250] terminating 

 in an angle near the tip j the lobe on the exterior edge, also, is 

 not apparent. 



Tt inhabits as far west as the Rocky Mountains. 



[Previously described by Weber as P. qutrcus. — Lec] 



ZOPHOSIS Latr. 



Z. RETICULATA. — Black ; posterior angles of the thorax elon- 

 gated ; elytra irregularly reticulate. 



Inhabits near the Rocky Mountains. 



Clypeus emarginate before : antennEB a little larger towards the 

 three exterior joints not rounded but truncated at tip, the ulti- 

 mate one subacute at tip, precisely resembling the corresponding 

 joint of Eun/chont as represented by Ilerbst, (pi. 5.) and not 

 larger than the preceding joint: palpi, terminal joint a little 

 larger than the preceding one : nientum widely emarginate, nar- 

 rower at ba.xe. not concealing the base of the maxilla3 so much as 

 that of Pim'lid blpnnctatn : thorax curvilinearly emar<Mnated 

 before for the reception of the head ; punctures very minute, 

 distant; anterior angles obtuse, s(Uiiewhat prominent; marijined 

 each side; posterior angles elongated, acute, closely embracing 

 the humeral angles: scutel none: elytra with obtuse, elevated, 

 irregular, somewhat reticulated lines.
