Massachusetts to Maryland, nol common. It is the Elater suturalis, Harris' Cat., ac- 

 cording to a specimen communicated to me by Dr. Harris. Dr. Mclsheimer describes his 

 specimen as having black tarsi, hut mi examination I find thai they arc only fuscous: in 

 mosl specimens they are no darker than the tibia, [n his specimen, as in Dr. Harris', 

 there is an oblong fovea at the apex of the <■ 1 \ j >* 1 1 ~. which, however, is wanting in my 

 I can be no doubl aboul the generic position of this species; it only 



differs from the neighbourin a in having the carina of the posterior thoracic angles

One specimen, Oregon. Although having the aame structure of antenna?, and the same 

 sculpture of thorax, as the preceding, this species, bj its form, approaches very closelj t" 

 the species of a subsequent division, containing C. pyrrhos: the triangular joints ol the 

 antennse, and the slightly convex front, require it to be placed in this division.
