a strong sharp sulcus, but no distinct row of punctures 
mesad of it; disc with eight strong striz, beset with 
small round rather weak punctures throughout, about 
7 punctures to a mm. On middle of elytron three striz, 
with two intervals, go in 2 mm. transversely. The two 
outer discal striz run to the apex, converging near it, as also 
do the two inner, but the four middle ones unite in two 
pairs, thus terminating, the outer pair 3 mm. and the inner 
pair 2 mm., before the apex. There is no basal incomplete 
stria, nor any sign of specialised discal punctures. The 
strie, with their punctures, resemble those of Morio, but the 
fossil is easily separated from that genus by the absence of 
specialised submarginal and discal punctures.

The type of Carabites, Heer, is an elytron 3:5 mm. long, 
from the Lower Lias of Switzerland. Our insect is of course 
not congeneric, but Scudder used Carabites in a general 
sense for Carabide not referable to a known genus, and I 
follow him in this usage, to avoid giving a new generic name. 
T do not know a living genus to which C. gardneri may be 
referred, but I am not familiar with more than a small 
fraction of the numerous genera. 
Elateride. 
Elaterites murchisoni (Giebel). 
Elytron as preserved 14 mm. long, the actual length was 
probably at least 15 mm.; width 45 mm.; nine longitudinal 
lines of small round punctures ; near the apex 10 punctures 
in 2 mm. of length, and three rows in 1 mm. transversely ; 
on middle of elytron two rowsin 1 mm. The shape of the 
elytron is about as in Agriotes, the apex forming a large 
angle. The punctures are about as in Pyrophorus, but those 
in the apical field are stronger, although the insect is not so 
large.

This is the type-specimen of Elatertum murchisoni, Giebel, 
1856, based on Westwood, Proc. Geol. Soc. London, 1854, 
p. 395, plate 16. f. 34. It has quite typical Hlaterid sculp- 
ture ; but the type of Elaterium is E.proneus, Westw., from 
the Purbeck, which has elongated punctures and, as Hand- 
lirsch remarks, is surely not congeneric. Hlaterites, Heer
