very different in form, which is much more like that of a true 

 jBuprestts ; and the color is also different, though that of the 

 head and thorax probably deceived hiui, bein_i; coppery in each, 

 thougli much more obscure in our insect. I have taken a variety 

 in this State differing greatly in color, so much so, that it might 

 lead to error unless actually compared. 



The color is bright green ; thorax on the disc tinged with 

 coppery, with a common green triangle extending from the 

 humerus to beyond the middle; beneath the green color is less 

 brilliant. Another variety lias the cupreous color of the thorax 

 confined to the lateral margin, the remainder being of the color 

 of the elytra. 



I may add to the specific description that the head has an or- 

 bicular indentation between the eyes, and a slightly indented 

 line on the vertex ; the scutel is altogether destitute of a trans- 

 verse elevated line; it is convex, and widely triangular; the 

 elytra are minutely serrate at tip. 



This species has characters in common with Buprrsth and 

 Agrilus, and it may perhaps belong to the latter.

 is ^1. que/rata, the other a variety of ^I. riridicuniis. — Lec]

1. A. RUFICOLLIS F. — We may add to the Fabrician charac- 

 ters that the head is profoundly indented on the vertex ; the in- 

 dented line is continued down the front ; the elytra are scabrous, 

 and at tip, as well as that of the abdomen, serrate. 



Var. a. Thorax obscure green. [ 162] 



Var. b. Thorax color of the elytra. 



The great indentation of the vertex distinguishes this species 

 from others of this country. Ilerbst's figure only tends to mis- 

 lead, if indeed it can be intended for this insect at all. It is too 

 robust, the thorax is not represented as indented, and the elytra 

 are punctured in striae, with large punctures. 



2. A. (;eminatus nob. — A numerous species ; the color of thu 

 head and thorax often resembling those of the preceding species, 

 but the acute, arcuated elevated line at the posterior angles, ia
