84 ORDER COLEOPTERA. 



the largest, is an undulating band extending nearly across the elytrum, and the last 



is a spot near the apex : the spots are surrounded with a black glossy border. The 



apex has a steel-blue reflexion, and is bidentate. 



This is one of the finest beetles belonging to this family : it varies in length from four 



to six-tenths of an inch. The bands are variable in number : they are found some with 



three, others with two, which is the most common, and still another variety, has only one. 



[ I have observed, in some of the plates, the color of the figure is too black, and the 



green too indistinct.] 



BuPREsTis . (Plate xxxi, fig. 11.) 



Slightly depressed, widened posteriorly and punctured. Mandibles naiTow, black ; beneath 

 purplish green : eyes black : antennae green : head and thorax green, cupreous and 

 metallic. Elytra bordered with metallic purple ; disk green, forming a middle lon- 

 gitudinal band ; also marked with four elevated lines, truncate, jnd terminated at 

 the inner angle with a minute spine. 

 This Ijeautiful species was found at Albany : its elytra are finely bordered with purple ; 

 the sutural line is divided into two near the base, and is dotted between. It appears to be 

 rare, as it is the only one I have seen in any of our collections. 



BupRESTis (Chrysobothris) dentipes (Germar). ( Plate v, fig. 2.) 



Depressed or flattened, oblong oval, purplish copper-color above ; beneath copper-colored, 



finely punctured. Surface covered in patches with a kind of shagreen. Thorax maiked 



with two elevated lines : elytra rounded behind. 



This species is still less convex than the divaricata : its metallic hues are less distinct, 



it is destitute of denticles at the apex of the wing-covers, its eyes are much smaller, and 



its mouth differently constructed. It inhabits the different species of oaks, and is not found 



about our fruit orchards or gardens. It is the B. characteristica of Harris ( New-England 



Farmer, Vol. viii, p. 2 ). 



BupRESTis (Chrysobothris) femorata (Fab.). (Plate V, fig. 3.) 



Rather depressed. Color black and bronzed above, glossy and metallic beneath : upper 



side the abdomen is green, punctured above and underneath. Eyes gray. Head is 



marked with an elevated line, and covered with short whitish hairs in fiont. Elytra 



rounded ; the posterior edge subserrate, or scarcely serrated. 



This species is smaller than the dentipes. It has a well marked tooth inside of the thigh 



of the forelegs. The elytra are rather shorter than the abdomen, and have an approach to 



three pair of impressed gray transverse spots. It varies in size ; not exceeding, however, 



half an inch in length. 



I took many individuals of this species in Canandaigua several years since, in June, 

 upon a black oak. The foregoing species appear to be widely distributed.
