Sp. Char. — Larva : Elongate, narrow ; head narrowed in front, small, 
evidently corneous, with two longitudinal sulci; antennae minute, jointed, 
inserted near the anterior angle of the head; thoracic and abdominal seg- 
ments similar in form, the latter nine in number ; the terminal segment 
furnished with a bifid tail. Length, 26-28 mm. ; greatest width. If mm. 
Ohs . — The possession of a corneous head with jointed apjiendagcs, a 
bifid tail, and uniform thoracic and body segments, through which the 
alimentary canal can he plainly seen, mark these remains as those of some 
Coleopterous insect, and there seems every probability of their near affinity 
to the genus Lycus, to the larvae of which they hear a striking resemblance. 
The frequency with which this larva occurs on the pieces of sliale 
from Vegetable Creek renders more than a passing recognition necessary. 
Acting on this belief, we venture to propose the above name for its reception, 
both as an index to the formation in which it occurs, and with the view of 
calling the attention of collectors to it. By this means, perhaps, other speci- 
mens may be obtained, throwing a further light on its affinities. 
Lampyridas are known from the Lias, and, according to Scudder, the 
family is moderately abundant in the Tertiarics.
