tei-minated by two very distinct spurs ; the tarsi long, and more 
slender towards the extremity *. 
Eubrxa, Zieg. Dej. 
The antennae slightly serrated, the second joint very small, the 
two following ones largest of all, and the last somewhat emarginate 
at the end, and tapering to a point ; spurs of the tibiae very small, or 
nearly null ; tarsi filiform f. 
The second tribe of the Malacodermi, or that of the Lampybides, 
is distinguished from the first by the enlarged termination of the 
palpi, or at least those of the maxillae, by their always soft, straight, 
depressed, or but slightly convex body, and by the thorax, sometimes 
semicircular, and at others nearly square or trapezoidal, that projects 
over the head, which it cither entirely or partially covers. The 
mandibles are usually small, and terminate in a slender, arcuated, very 
acute point, that is generally entire. The ixenultimate joint of the 
tarsi is always bilobate, and the crotchets of the last have neither 
dentations nor appendages. 
The females of some are apterous, or have but very short elytra. 
When seized, these Insects irress their feet and antennce against 
their body, and remain as motionless as if they were dead. Several, 
thus situated, curve their abdomen underneath. They comprise the 
genus 
Lampyris, Lin. 
Antennae closely approximated at base, the head either exposed and 
prolonged anteriorly in the manner of a snout, or for the greater 
part, or entirely, concealed under the thorax ; eyes of the males large 
and globular ; mouth small. Such are the characters of a first 
division of this tribe, which we will subdivide into those in which 
neither sex is phosphorescent, and those in which the females at least 
are possessed of that faculty. Both sexes of the former are provided 
Avith wings, have their head exposed, and frequently narrower and 
extended anteriorly, or in the form of a snout, and the thorax widened 
posteriorly with pointed lateral angles. The two or three ultimate 
annuli of their abdomen are destitute of that pale yellowish or whitish 
tint that is always found on this part of the body in the true Lampy- 
rides, and which announces their phosphorescence. The elytra, in 
several, widen behind, and are sometimes strongly dilated and rounded 
posteriorly, in the females particularly. They are densely punctured, 
and frequently reticulated. 
Lycus, Fab. Oliv. — Cantharis, Lin. 
We restrict this subgenus to those species of Fabricius, in which 
the snout is as long as the portion of the head that precedes it, or
