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

 slightly crenated, interstitial lines nearly flat. External edges 



of the tibiaa (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 robust, and has some resemblance to the figure 

 of HarpaluB dubius in Palisot de Beauvois. Can it be a 

 Morio ? 



The three following are ElateridcB, which, with two smaller 

 American species and the European E. unguliserris 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 

 antennas simple and the nails pectinated. 



Notlwra 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 with an impressed line, 

 obsolete before. Elytra punctato-striate, punctures distinct; 

 interstitial lines minutely punctured. Length about -^ inch. 

 To this very common species you returned me the name of 

 Elater dispar ? 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. elongatus Beauv., both of which Schon- 

 herr makes synonymous with the dispar of Herbst. Is it not 

 rather the cinereus of Weber ? 



Nothora 2. Dark castaneous, antennae and feet paler ; body 

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

 the preceding; head and thorax with dilated punctures, the 

 latter with an abbreviated, dorsal line at base, obsolete on the 

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

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