base with distinct, deep punctures. Elytra glabrous, strijE deep, 

 slightly crenated, interstitial lines nearly flat. External edges 



of the tibia3 (except the superior portion 



of the anterior) spinous, inner edges with 



strong bristles or elongated, slender spines ; 



tarsi spinous, nails simple. Specimen, a 



female sent me from Philadelphia, in which 



'^' ^ ■ vicinity it is said to be not uncommon. It 



is remarkably robusf, and has some resemblance to the figure 



of Harpalus diibius in Palisot de Beauvois. Can it be a 



Morio ? 



The three folloAving are Elateridce^ which, with tAvo smaller 

 American species and the European E. unguUserris and fusci- 

 pes Schonh., I propose to include in a subgenus denominated 

 Nothora, distinguished by having the thorax and coleoptra 

 equally broad at base, and attenuated at the extremities, the 

 antenna simple and the nails pectinated. 



Notliora 1. Pale reddish brown, densely covered with de- 

 pressed, pale, ochreous hairs. Antennae with simple, elongated, 

 obconic joints in both sexes. Head and thorax with distinct, 

 dilated punctures, the disk of the latter Avith an impressed line, 

 obsolete before. Elytra punctato-striate, punctures distinct; 

 interstitial lines minutely punctured. Length about -.j^^ inch. 

 To this very common species you returned me the name of 

 Elater dhpar? Herbst. It is certainly specifically distinct from 

 the next, and to neither of them can we apply the name of E. 

 lividus DeGeer, and E. elongatns Beau\"., both of which Schon- 

 herr makes synonymous v<'\X\\ the dlspar of Herbst. Is it not 

 rather the cinereus of Weber ? 



Notliora 2. Dark castaneous, antenna^ and feet ])aler ; body 

 covered with sliort, depressed, yellowish hairs. Antennas as in 

 the preceding ; head ond thorax with dilated j)unctures, the 

 latter Avith an abbreviated, dorsnl line at base, obsolete on the 

 middle ; elytra punctato-striate, Avith small, setiferous punctures 

 on the interstitial lines. Length nearly ^ inch. Can this be
