NEMOGNATHA IMMACULATA. 



SPECIFIC CHARACTER. 



Lemon-yellow, immaculate ; elytra pale yel- 

 lowish, with scattered punctures ; maxillae not 

 longer than the thorax, and, with the antennae 

 and palpi, black. 



DESCRIPTION. 



Jintennse black, basal joint pale testaceous; 

 eyes, maxillae, palpi, and tips of the tarsi, black ; 

 elytra irregularly punctured, naked, polished. 



OBSERVATIONS. 



It inhabits the plains of Missouri, and was 

 captured by Mr. Thomas Nuttall, on a species 

 of thistle (Carduus) ; I have since observed 

 it in some plenty in the same locality. It 

 seems to be allied to the Zonitis pallida of 

 Fabricius, judging by his description of that 

 insect.
