2SS APPENDIX. 



slightly excurved ; elytra nearly rectilinear, not dilated at 

 the posterior curvature ; punctures dense, profound, rather 

 large ; beneath blackish-grcen; tarsi dark testaceous. 



Length from two-fifths to nine-twentieths of an inch. 



This is not the Lagria aenea, Fabr. Ent. Syst. Suppl. 

 as the late Mr. F. V. Melsheimer supposed it to be, fw in- 

 dependently of the different specific characters in the des- 

 cription of that insect, it has since been referred by that 

 author to the genus Dasytes, and must therefore be a Pen- 

 tamerous insect. The circumstance of that species being 

 removed from the genus Lagria enables me to retain the 

 specific name given by Mr. Melsheimer. We obtained a 

 specimen on Red river. 



LYTTA, Fabr. 



L. aenea, nob. varies in being green, with black tarsi. 

 The antennae of this species resemble very much those of 

 the genus Mylabris. 



COCCINELLA. 



C. labiculata, nob. This species varies considerably in 

 colour, but not, as I believe, in the number or arrangement 

 of its spots. 



Var. oi. Spots of the elytra ocellate, being surrounded by 

 a yellowish areola. 



Var. /3. Elytra yellowish-white, with the black spots as 

 in the species. 



RYNCHITES, Herbst. Latr. 



R. rubricollis. Blued-black; thorax and feet rufous; 

 elytra striate, hairy. 

 Inhabits United States.
