inhabitant of the United States; I have found it in Missouri, 

 Arkansa, and the North West Territory, as well as in Pennsyl- 

 vania. 



Lower right figure : the line represents the natural size, with 

 a lateral enlarged view of the head. 



Calandra tredecim-punctata, Var. Desc. Body punc- 

 tured; beneath black, with a cinereous shade in a particular 

 light, and with numerous large punctures ; head black ; rostrum, 

 dilated portion longer than broad, but more dilated at tip, and 

 with a deeply impressed puncture at its base above : thorax san- 

 guineous, with five black spots, of which two are placed on each 

 side, the posterior one larger and generally oblique, and one is 

 central fusiform: scutel black: elytra sanguineous, with punc- 

 tured striae; interstitial lines flat, with dilated punctures; two 

 small marginal spots; a large common transverse spot on the 

 middle, and a common tip consisting of about one-third of the 

 length of the elytra, black. 



The spots of the elytra appear at first view to be formed and 

 located differently in this from those of the preceding, yet by 

 dilating the two central elytral spots of the preceding insect trans- 

 versely, and enlarging the posterior spots in a posterior and 

 transverse direction, we shall be able to exhibit an arrangement 

 precisely comforable to that of the present variety. 



The spots of the elytra in this variety are subject to some 

 variations; the transverse spot on the middle of the elytra is 

 divided into two on one of my specimens ; the posterior common 

 spot is subcordate, being much narrowed behind in another, and 

 in' a third is a black spot on each elytrum, insulated from the com- 

 mon terminal spot which is much narrowed. 



This insect is a native of Missouri and Arkansa, as well as of 

 the Atlantic States. 



The lower left figure ; the natural size is represented by a line, 

 above which is an enlarged view of the head. 



Calandra quinqtje-punctata. — Specific character. Black ; 

 thorax sanguineous, with five black spots ; elytra with a sanguine- 

 ous exterior submargin. 



Desc. Body punctured, beneath black, with a very slight 

 cincereous reflection in a particular light: rostrum, dilated por- 

 tion longer thim broad, but wider at tip, and with a deeply im-
